The Role of Climate Tech in Decarbonising the Public Sector

Fuel Type Breakdown Britain’s electricity generation in August 2025 was led by wind, which supplied 26% of the mix. While this marked a strong showing, it was notably down from 32% in August 2024. Despite the decline, it represented the second-highest August wind share in the past five years, underscoring the technology’s continued importance. Gas accounted for 23%, a sharp decline from August 2021 (36%), 2022 (48%), and 2023 (35%), though still above its 17% share in August 2024. These fluctuations reflect both progress in reducing dependence on fossil fuels and the current limitations of grid storage, underscoring gas’s continued role as a flexible backup source. Electricity imports accounted for 19%, their highest August share in the past five years and 5 percentage points higher than in August 2024. This growing dependence raises concerns about energy security and highlights the importance of strengthening domestic generation capacity and storage. Nuclear output fell to 11%, its lowest August contribution in the past five years, down 7 percentage points from August 2024 and 4 points below its levels in August 2021–2023. Biomass provided 8%, up from 7% in August 2024 and higher than its contributions in August 2021–2023, confirming its role as a reliable renewable source. Solar reached 10%, its highest August share in the past five years and 2 percentage points above August 2024, reflecting favourable summer conditions and incremental growth in installed capacity. Hydropower contributed 1%, broadly consistent with previous August levels. Storage matched its joint-highest August contribution at 2%, equalling 2024 and demonstrating the growing role of flexibility solutions in balancing the grid. Zero-Carbon Sources & Carbon Intensity Zero-carbon sources; wind, solar, nuclear, and hydro, accounted for 62% of Britain’s electricity in August 2025, the highest share for any August in the past five years. This milestone reflects steady structural progress in decarbonising the grid. Despite the strong zero-carbon contribution, carbon intensity rose to 123 gCO₂/kWh. While this was the second-lowest August value in the past five years, it was 48% higher than the record-low 83 gCO₂/kWh achieved in August 2024. The increase was driven by reduced nuclear and wind contributions alongside higher gas and import reliance. Looking at broader trends, the 12-month rolling average for zero-carbon generation declined slightly to 51%, down 1 percentage point from the previous 12-month period. This plateau indicates a temporary slowdown in renewable integration. Meanwhile, the rolling average carbon intensity rose by 6% to 134 gCO₂/kWh, emphasising the need to accelerate clean energy deployment. Concluding Remarks August 2025 saw wind retain its lead as the largest generation source, though its share dipped below 2024’s record levels. Gas rebounded from its unusually low contribution last year, while imports reached a five-year August high, highlighting ongoing vulnerabilities in energy security. Nuclear’s decline to its weakest August performance in five years further compounded these challenges. Nevertheless, the record-high share of zero-carbon sources for August, alongside growth in solar, biomass, and storage, demonstrates resilience and long-term progress in decarbonisation. Sustaining momentum will require renewed investment in renewables, reinforcement of grid infrastructure, and policies that strengthen domestic supply to ensure both cleaner and more secure electricity in the years ahead.

Scene Setting: A world on fire, a business community looking away In the wake of stark warnings from the Intergovernmental Panel on Climate Change (IPCC), the imperative for global nations and the businesses that operate within them to expedite climate action has never been more urgent. Yet, 2024 offered a sobering backdrop. More than 60 countries went to the polls, including major players like the US, UK, India, South Africa, Pakistan, and Russia, but climate concerns scarcely featured in manifestos. Global temperatures soared, making 2024 the hottest year on record, breaching the Paris Agreement’s critical 1.5°C threshold with an average global rise of 1.6°C. Instead of urgency, we saw political backtracking on commitments and rising public scepticism, as nationalist politics across the US, UK, and Europe reshaped climate discourse. The second Trump Administration has already reversed U.S. environmental policies put in place by the Biden Administration, Russia’s approach was deemed “critically insufficient” by the Climate Action Tracker, and developing nations like India and Pakistan are prioritising growth over emissions reduction. Against this political backdrop, businesses are increasingly echoing the same short-termism. Today in 2025, the focus has shifted toward low-value investments, short-term paybacks and high percentage RoIs, rather than the long-term investments required to align with net zero. The reality is clear: governments and businesses alike are kicking the climate can down the road at the very moment when decisive action is most needed. In our experience, this is a big mistake. Taking a long-term view on sustainability and particularly on decarbonisation offers significant long-term benefits for organisations, increases asset and company valuation and supports growth. The Rise of Short-Term Thinking in Business Business leaders have long understood that shareholder expectations and competitive pressures drive decision-making. However, what we are now seeing is a dangerous narrowing of focus. Instead of aligning investment and strategy with the multi-decade challenge of decarbonisation, many firms are prioritising projects with immediate financial returns, often within a 2-3 year window. This shift is particularly troubling because: The carbon reporting landscape is becoming more complex. Regulations such as the EU’s Corporate Sustainability Reporting Directive (CSRD), the UK’s Transition Plan Taskforce (TPT) framework, and the growing alignment with the International Sustainability Standards Board (ISSB) are forcing businesses to measure and disclose with greater transparency. Yet, disclosure does not equal action. The window for effective transition is closing. Science shows that emissions must peak before 2030 and fall by nearly half by 2035 to stand a chance of limiting warming. A short-term financial focus is incompatible with this timeline. Competitive positioning is at risk. While some businesses see sustainability as an “extra cost,” those that fail to transition risk stranded assets, supply chain disruption and reputational decline as customers and investors demand evidence of resilience. The Shift Away from Net Zero: Sentiment vs. Reality Across boardrooms in 2025, there is a noticeable cooling of enthusiasm toward net zero. Where once CEOs boasted about ambitious targets, today there is a recalibration, or in some cases, a retreat. Several factors underpin this shift: Economic volatility. Inflationary pressures, higher interest rates, national insurance increases and supply chain disruptions have led many firms to re-evaluate capital deployment. Long-term sustainability projects are being deferred in favour of “business continuity”. Investor pressure for short-term returns. Despite growing ESG funds and sustainable finance frameworks, mainstream investors remain focused on quarterly earnings. Executives are rewarded for near-term profit, not 2040 climate goals. Perceived political cover. With governments themselves slowing climate ambition, businesses feel less exposed when reducing or delaying their own commitments. This sentiment shift is dangerous. Net zero is not a PR exercise but a structural economic transition. Those companies stepping back today risk not only missing climate targets but also creating vulnerabilities within their operations and missing out on significant financial benefits. The Inadequacies of Short-Term Planning 1. Misaligned Investment Horizons Sustainability, by its very nature, requires investments that yield benefits over decades. Renewable energy infrastructure, enhanced electrical supply infrastructure, electrification of fleets, electrification of heat, circular economy design, or large-scale efficiency retrofits often require 7–15 years to fully deliver ROI. A focus on 2-3 year payback periods screens out precisely the projects needed to build resilience and future profitability. 2. Greenwashing Over Governance Short-termism often leads to “optics over outcomes.” Companies spend on branding, marginal improvements, or low-cost offsets instead of transforming business models. This erodes trust among investors, employees, and consumers alike. 3. Regulatory Lag Becomes Risk Exposure The complexity of carbon reporting and disclosure requirements is accelerating, not slowing. Businesses that fail to prepare for robust compliance regimes will face mounting costs, penalties, and reputational damage. 4. Failure to Secure Financing Sustainable finance is evolving. Lenders and investors increasingly evaluate climate transition plans and exposure to transition risks as part of their risk models. Companies unable to demonstrate credible long-term planning will face higher financing costs or lose access to capital entirely. The Case for Long-Term Sustainable Investment Insight from investment research consistently shows that sustainability and profitability are not mutually exclusive. In fact: Firms with strong ESG performance often deliver higher risk-adjusted returns. Studies by MSCI and Morningstar suggest ESG-aligned portfolios have outperformed benchmarks over the past decade . Company Valuation. Investing in on-site technology and infrastructure that will support carbon reduction and energy efficiency will increase asset values which in turn will support valuation multiples. Resilience pays. Companies that invested early in renewable energy and efficiency are now benefiting from reduced exposure to volatile fossil fuel prices. Investor sentiment is shifting. Even though short-term profit dominates headlines, global frameworks such as the UN COP26 initiated Glasgow Financial Alliance for Net Zero (GFANZ) are embedding climate criteria into long-term capital allocation. The lesson is clear: businesses that look beyond the immediate payback horizon will be better positioned to attract capital, manage risk, and capture growth opportunities. What Businesses Need to do to Reframe Their Approach To break away from short-termism, businesses need to embrace three core principles: 1. Transition Planning as Strategy Carbon disclosures should not be viewed as a box-ticking exercise. Instead, businesses should integrate them into strategic planning, aligning investment horizons, operational transformation and risk management around a clear net zero pathway. 2. Investment Criteria Must Evolve Payback periods need to be redefined. Businesses should apply broader lenses, incorporating avoided carbon costs, resilience benefits, brand equity, and future financing conditions. A total value return approach, not just a financial one. 3. Align Incentives with Long-Term Outcomes Boards and investors should tie executive compensation not just to annual returns but to delivery against long-term climate and sustainability targets.  The edenseven View: From Short-Term Gains to Lasting Value At its heart, the danger of short-termism is not just the failure to reduce emissions; it is the erosion of business competitiveness, resilience, and relevance. The narrative of “we cannot afford sustainability” is inverted. In reality, businesses cannot afford inaction. Our advice is clear: Set credible financial and environmental targets align ed with net zero. Reframe investment decisions with a long-term lens that includes financial, environmental, and reputational dimensions. Engage proactively with regulators and stakeholders to shape and anticipate compliance requirements. Embed sustainability into corporate culture, governance, an d reporting. Ensure that your data capture and reporting processes are robust, consistent, compliant and assured. By doing so, companies move beyond compliance and optics into a position of leadership, attracting capital, customers, and talent while securing long-term viability Conclusion: A Call to Leadership The world in 2025 is defined by contradiction. On one hand, the climate crisis accelerates, with record-breaking temperatures and increasingly complex carbon reporting frameworks. On the other hand, business sentiment retreats, focusing narrowly on short-term paybacks. This is unsustainable. Businesses that prioritise immediate returns over long-term resilience are missing an opportunity for long-term growth. By contrast, those that embrace sustainable investment as a core strategy will not only meet compliance requirements but also unlock profitable growth, resilience, and trust. Kicking the climate can down the road only makes the future more expensive and challenging for businesses, investors, and society alike. The choice is clear: chase shadows in pursuit of short-term gains, or invest in the foundations of lasting value .

Fuel Type Breakdown Britain’s electricity generation in July 2025 was led by gas, which accounted for 25% of the energy mix. While this marks a continuation of gas as a primary source, it represents its second-lowest July share in the past five years, signalling gradual progress in reducing reliance on fossil fuels. Electricity imports contributed 20% of the mix, their highest July share in the past five years. This increase, which placed imports ahead of wind generation, raises concerns about energy security and highlights the importance of bolstering domestic supply. Wind contributed 19% to the electricity mix, a 2-percentage point decline from July 2024 and 10 points below its July 2023 share, underscoring seasonal variability and the need for continued investment in grid flexibility. Nuclear provided 15%, down 1 percentage point year-on-year but consistent with its average July performance over the past five years, maintaining its role as a stable baseload low-carbon source. Solar generation rose by 2 percentage points year-on-year to reach 11%, its highest July contribution in the last five years. Biomass and storage also saw modest increases of 1 percentage point each, reaching 8% and 2%, respectively, both their highest July shares in the past five years. Hydropower remained stable at 1%, in line with its contribution in July 2024. Coal remained absent from the generation mix, continuing its phase-out completed at the end of 2024. Zero-Carbon Sources & Carbon Intensity Zero-carbon sources, including wind, solar, nuclear, and hydro, provided 48% of Britain’s electricity in July 2025. While up from 34% in July 2021, this figure was slightly below July 2023’s 52% and only a marginal improvement over the 47% recorded in July 2024, reflecting limited year-on-year progress. Carbon intensity rose to 129 gCO₂/kWh, a 13% increase compared to July 2024, driven by lower wind output and increased gas and import use. Looking at broader trends, the 12-month rolling average for zero-carbon generation held steady at 51%, unchanged from the previous 12-month period. This plateau suggests that the pace of renewable integration has temporarily slowed. The rolling average carbon intensity rose slightly to 131 gCO₂/kWh, up from 129 gCO₂/kWh in June, reinforcing the need for continued decarbonisation efforts. Despite these short-term challenges, the rolling carbon intensity remains the lowest seen in the past five years, reflecting sustained long-term progress. Concluding Remarks July 2025 saw gas return as the leading fuel source, while wind’s contribution fell below recent seasonal norms. Rising imports and a modest increase in carbon intensity signal emerging challenges around energy security and clean generation. Nevertheless, gains in solar, biomass, and storage demonstrate resilience within the zero-carbon segment. The continued absence of coal and stable nuclear output reinforces the structural transition underway. To maintain momentum, renewed focus is needed on accelerating renewable deployment, strengthening grid flexibility, and supporting domestic capacity. These are critical steps to ensure consistent progress toward a low-carbon energy future. Britain's Electricity Summary Charts

Fuel Type Breakdown Britain’s electricity generation in June 2025 was led by wind, which contributed 31% of the energy mix, its highest June share in the past five years. This marked a 6-percentage point increase compared to June 2024 and was double the share recorded in June 2021, reinforcing wind’s growing dominance in the summer energy mix. Gas accounted for just 17% of electricity generation, its lowest June share in the past five years. This represented a 2-percentage point decline from June 2024, and a 50% drop compared to June 2021, highlighting continued progress in reducing reliance on fossil fuels. Solar generation rose by 2 percentage points year-on-year to reach 12%, its highest June contribution in the last five years. Biomass and storage also saw modest increases of 1 percentage point each compared to June 2024, contributing 8% and 2%, respectively, indicating incremental gains in both dispatchable renewable supply and energy flexibility. Nuclear contributed 15% to the mix, down 2 percentage points from June 2024 but consistent with its average performance over the past five years, maintaining its role as a stable, low-carbon baseload source. Hydropower remained steady at 1%, while coal remained absent from the generation mix for the second consecutive June, following its full phase-out. Electricity imports fell to 15%, a 4-percentage point decline from June 2024. While still notable, this decrease points to an improving balance between domestic generation and external supply. Zero-Carbon Sources & Carbon Intensity Zero-carbon sources, including wind, solar, nuclear, and hydro, delivered 61% of Britain’s electricity in June 2025, the highest June share in recent years and an 11-percentage point increase from June 2024. This increase in clean generation contributed to a further decline in carbon intensity, which fell to 98 gCO₂/kWh, 1% lower than the same month last year. Looking at broader trends, the 12-month rolling average for zero-carbon generation held steady at 51%, consistent with the previous 12-month period. Meanwhile, the rolling average carbon intensity dropped to 129 gCO₂/kWh, its lowest level in the past five years and 4% below the level recorded a year earlier, signaling sustained, long-term progress in grid decarbonisation despite short-term variability. Concluding Remarks June 2025 marked a significant step forward in Britain’s clean energy transition, with wind reaching its highest June share in five years and solar achieving a new seasonal peak. These gains, alongside growth in storage and biomass, pushed zero-carbon sources to a five-year high for the month and drove carbon intensity to one of its lowest recorded levels. The continued decline in gas and the absence of coal underscore the pace of decarbonisation. However, the slight drop in nuclear output, modest hydro performance, and the ongoing reliance on imports highlight areas where further progress is needed to strengthen domestic energy resilience. Sustained investment in renewable generation, grid flexibility, and energy storage will be key to building on this momentum and ensuring continued reductions in carbon intensity across all seasons.

edenseven are following trends in the renewable energy sector closely, as decarbonising the energy sector is vital for ensuring a sustainable future and achieving Net Zero. Considering the recent DESNZ quarterly update of the renewable energy planning database, we have produced a consolidated summary of projects in the United Kingdom that have received planning permission. We will continue to release updates each quarter. INSIGHT Over the past 12 months, the UK approved 690 solar PV projects, 19% lower than the previous 12-month period. Despite the decline in project numbers, the total approved energy capacity rose by 16%, reaching the highest level for solar PV granted planning permission in any 12-month period over the last 16 years. Onshore wind approvals increased, with 46 projects granted permission, up by 28% year-on-year. However, the total energy capacity from these projects fell by 33%, and the average capacity per project dropped by 47%, reflecting a shift toward smaller-scale onshore developments in the last 12-months. Offshore wind saw a 67% increase in project approvals, with five projects granted permission. Yet, total energy capacity fell by 61%, and the average capacity per project declined by 77%, marking a significant reduction in project scale. In total, the combined approved energy capacity from solar PV, onshore wind, and offshore wind over the last 12 months reached 6,745 MW, ranking fourth-highest across the past 16 years.

In today's rapidly evolving business landscape, Environmental, Social, and Governance (ESG) factors have moved from niche considerations to critical drivers of long-term value, investor confidence, and societal impact. Companies are increasingly recognising the imperative to address their environmental footprint, foster positive social contributions, and uphold robust governance standards. However, despite this growing awareness and investment, a significant hurdle remains for many organisations: the common misconception that ESG can simply be an add-on . Too often, we see ESG treated as a separate department, a compliance checklist, or merely a side project tacked onto existing operations. This "bolt-on" approach , while seemingly an easy entry point, is a primary reason why even well-intentioned ESG initiatives ultimately fail to deliver meaningful, transformative impact. When ESG isn't woven into the very fabric of a company's strategy, culture, and decision-making processes, it becomes just another isolated function, lacking the power and resources to drive real change and unlock genuine value. This article will delve into why this approach falls short and, more importantly, outline how a strategic, integrated approach to ESG can lead to tangible business outcomes and sustainable growth. The Challenge "We have a sustainability team of 3 people trying to transform a company of 10,000." This candid observation highlights the fundamental flaw in many organisations' approach to ESG. When ESG is treated as an isolated function, disconnected from the core business, it struggles to gain traction and deliver real transformation. Uncovering the Shortcomings of This Approach ESG treated as a separate function rather than core business strategy Sustainability goals disconnected from business objectives and KPIs Executive teams struggle to weave ESG into existing strategic planning processes ESG initiatives compete against business priorities instead of enabling them Lack of integration creates silos and limits transformation impact Solution Framework: Making ESG a Strategic Enabler What's The Solution? To move beyond the bolt-on approach, ESG must be strategically integrated into every facet of the business. This shift transforms ESG from a compliance burden into a powerful driver of competitive advantage and sustainable growth. This means businesses need to: Embed ESG considerations into annual strategic planning and budget cycles Align ESG materiality assessments with business risk and opportunity mapping Integrate sustainability metrics into core business dashboards and board reporting Make ESG performance criteria part of business unit strategy reviews Connect ESG goals to market expansion, operational efficiency, and innovation pipelines Train leadership teams on ESG as competitive advantage, not a compliance burden How edenseven Helps: Enabling Integrated ESG Strategies Are your ESG efforts feeling disconnected and underperforming? edenseven closes the gap between ambition and execution. We combine deep technology understanding with real-world market experience to empower companies to not just meet climate goals, but to achieve sustainable, profitable growth . We design bespoke, data-driven sustainability strategies that are fully integrated into your core business, turning ESG into a powerful strategic enabler that unlocks new opportunities and mitigates risk, rather than a costly, isolated add-on.

Fuel Type Breakdown Britain’s electricity generation in May 2025 was led by wind, which contributed 27% of the energy mix, its highest May share in the past five years. This marked an 8 percentage point increase compared to May 2024, reinforcing wind’s role as the backbone of Britain’s clean energy supply. Gas, on the other hand, accounted for just 20% of the electricity mix, down 5 percentage points from May 2024 and its lowest May contribution in five years. Notably, gas generation in May 2025 was half of that in May 2021, signalling measurable progress in reducing reliance on fossil fuels. Nuclear power contributed 15% to the mix, a figure that has remained relatively stable in recent years. While slightly below the 17% share seen in May 2022 and 2024, it matches contributions in May 2021 and 2023, reflecting a continued but stagnant role in the generation mix. Solar generation rose significantly, climbing 4 percentage points year-on-year to reach 12%, its highest May contribution in the last five years. This growth underscores solar’s expanding role in supporting seasonal energy demand. Biomass remained consistent, supplying 7% of Britain's electricity in May 2025, in line with its contribution in May 2024. Hydropower also maintained a consistent presence at 1%, though this was below the 2% observed in May 2022. Electricity imports fell slightly to 17%, down from 19% in May 2024, but still substantially above the 2% recorded in May 2022. Meanwhile, storage technologies contributed 2%, marking their highest May share in the last five years and reflecting incremental progress in energy flexibility. Coal remained absent from the generation mix in May 2025, following its complete phase-out from the grid. Zero-Carbon Sources & Carbon Intensity Zero-carbon sources, including wind, solar, nuclear, and hydro, delivered 57% of Britain’s electricity in May 2025, the highest May share in recent years and a 12 percentage point increase from May 2024. This boost in clean generation contributed to a notable reduction in carbon intensity, which fell to 106 gCO₂/kWh, 15% lower than the previous year. In longer terms, the 12-month rolling average for zero-carbon generation reached 50%, up 1% from April’s update but still 1% below the level seen one year earlier. In contrast, the rolling average carbon intensity sits at 129 gCO₂/kWh, the lowest level of the past five years, indicating gradual improvement despite short-term fluctuations. Concluding Remarks May 2025 saw a strong rebound in wind and solar generation, helping to push zero-carbon sources to their highest May share in recent years and driving carbon intensity to new lows. The continued decline in gas and the absence of coal signal real progress, although the stability of nuclear, combined with limited hydro output and a marginal decline in the 12-month rolling average energy generation from zero-carbon sources, highlight the importance of accelerating renewable deployment to maintain momentum. With imports still high and storage only beginning to scale, the data points to both achievements and remaining vulnerabilities. To ensure long-term resilience and carbon reduction, sustained investment in domestic renewables and flexible technologies will be essential. Britain's Electricity Summary Charts

As energy prices climb, staff costs rise, and local authority budgets tighten, leisure centres across the UK are navigating choppy waters. Nowhere is this pressure felt more acutely than in facilities with swimming pools. These highly valued public assets are also among the most energy-intensive parts of any leisure operation, with heating, ventilation, water treatment, pumps and lighting systems operating almost constantly. According to a Lords report, between 2021 and 2024, 77 local authority managed leisure centres across the UK closed, many citing increases in utility costs as a contributing factor. In 2023, a medium sized operator of public leisure centres announced that it's utility costs had increased from £8m in 2021 to an estimated £24m in 2024. Yet, despite these pressures, swimming pools remain a vital part of the health and wellbeing infrastructure in our communities. The challenge is to safeguard their future by reducing operational costs and environmental impact while maintaining, or ideally improving, comfort and safety for bathers. This is where a focused, evidence-led approach to energy efficiency becomes not just a sustainability initiative, but a financial and operational necessity. Understanding the Challenges Operators of swimming pools in the public and private sectors are facing a perfect storm: Rising utility costs : Volatile energy markets and increasing wholesale prices mean that the cost of running a pool is often the single largest line item in an operator's budget. Ageing infrastructure : Many leisure centres were built decades ago, with plant and building fabric now well beyond their optimal design life. Staffing pressures : Increased employer National Insurance contributions, inflationary wage growth, and recruitment challenges in technical and operations roles strain budgets further. Local authority cuts : For council-run sites or those operated under local authority contracts, budget reductions mean less funding for capital improvements, making it harder to invest in long-term savings. In this environment, energy efficiency isn't just about sustainability; it is core to financial survival. Ten Focus Areas for Energy Efficiency in Swimming Pool Operations edenseven have worked with a wide range of leisure operators across the UK, from large national chains, local authority and privately run leisure centres and single-site independents. While every facility is unique, there are ten consistent focus areas that can help reduce costs and improve user experience.  1. Pool Hall Air Handling Systems Air handling units (AHUs) that serve the pool hall are often some of the most energy-intensive pieces of equipment in a leisure centre. Retrofitting systems with high-efficiency heat recovery, variable speed fans, and improved controls can yield significant savings. Maintaining optimal humidity and air temperature also reduces condensation and improves comfort and reduces building degradation. 2. Pool Water Heating and Temperature Management Upgrading boiler systems or integrating renewable sources such as heat pumps can drastically reduce energy usage. Modern controls, temperature stratification management, and insulation of pipework all contribute to system efficiency. Managing water temperatures to an optimal level reduces the need for backwashing. Higher pool water temperatures lead to increased microbiological growth and a higher need for backwashing and chemical dosing. 3. Lighting Efficiency LED lighting retrofits, particularly in pool halls and plant rooms, provide rapid returns on investment. Coupled with intelligent lighting controls (e.g., occupancy sensors in changing villages and toilets, and daylight dimming), this can lower costs while enhancing visibility and safety. 4. Building Fabric and Insulation Improved insulation of walls, roofs, and glazing can reduce heat loss, especially in pool halls where thermal demand is constant. Draught-proofing and maintenance of seals around windows and doors are low-cost measures that can have a noticeable impact. 5. Water Treatment System and Backwash Optimisation Advancements in filtration and chemical water treatment technologies, such as glass-media filtration and UV treatment, can reduce the need for chemical dosing and water changes. Smart controls help optimise chemical usage, water balance, and backwash schedules, lowering energy and water consumption. 6. Pool Covers and Evaporation Management Heat loss due to evaporation is one of the largest energy drains in any pool. High-quality, well-fitted pool covers can reduce overnight losses dramatically. Automatic covers also improve usability and safety. Consideration should be given to using surplus heat from other parts of the operation or other local businesses if possible - data centres or industrial processes could prove to be ideal partners. 7. Smart Controls and Building Management Systems (BMS) Many leisure centres are under-utilising their existing BMS or lack one altogether. Integrating systems and enabling real-time monitoring and automated control can unlock both energy and operational efficiencies. 8. Renewable and Low Carbon Technologies On-site solar PV, air or ground source heat pumps, and battery storage can help offset rising energy prices. While capital intensive, these measures may qualify for grant support or financing options that align with local authority decarbonisation plans. 9. Staff Training and Customer Engagement Empowering staff with energy awareness training and involving them in optimisation routines often leads to behavioural changes that enhance the impact of technical interventions. From plant operators to lifeguards, everyone has a role to play. Engaging with customers to shower before using the pool reduces biological loading and the need for chemicals and backwashing, saving water, energy and chemicals. 10. Data Monitoring and Continuous Improvement You can't manage what you don't measure. Installing sub-metering, using analytics platforms like cero.earth, and setting performance benchmarks allows leisure centre operators to track progress and target interventions more precisely. This data-led approach drives accountability and long-term success. Planning the Journey: From Audit to Action There is no one-size fits all solution, but there is a process. Most successful transformations start with a detailed energy and plant condition audit, tailored to the unique operational profile of the site. From here, a prioritised action plan can be developed, balancing short-term wins with longer-term investments. Understanding funding routes for public sector managed facilities is also critical. Many operators overlook opportunities for central government or local authority-backed capital funding. Our team has supported clients in identifying and securing funding through schemes such as the Public Sector Decarbonisation Scheme and local net-zero initiatives. Crucially, implementation must be done in a way that minimises disruption to operations and maintains health and safety standards. That means working closely with operational staff, technical teams, and supply chains. A Sustainable Future for Swimming At edenseven we believe that every leisure centre and swimming pool in the UK can be part of a more sustainable future, one where communities continue to benefit from the physical and mental wellbeing that swimming pools and leisure centre facilities offer, without shouldering unsustainable costs. Our role as a sustainability consultancy is not to offer off-the-shelf solutions, but to partner with clients to understand their context, build the right roadmap, and support delivery at every stage. From strategic advice and audits, through to technical specification and project management, our credibility is built on a track record of helping leisure operators navigate these exact challenges. If you are responsible for a facility that includes a swimming pool, now is the time to act, come and talk to us . Rising costs are unlikely to reverse themselves, but with the right expertise and a structured approach, they can be managed and even turned into opportunities to improve performance and bather comfort, engage with you customers and improve your leisure centre’s environmental impact.

Managing Partner, Pete Nisbet, explains more: Over 80% of consumers say they're willing to pay more for sustainable products. But here’s the catch: trust is fragile . Too many claims are vague, inconsistent, or unverifiable. And consumers are noticing. Greenwashing isn’t just a PR problem, it’s a business risk. Transparency and accountability are no longer optional. Credible data, third-party verification, and measurable outcomes are essential. They don’t just protect you, they future-proof your business. Because once trust is broken, it’s hard to rebuild. Over half of consumers say they’d stop buying from brands they believe mislead on sustainability. That’s not just reputational damage, it’s lost customers, investment, and talent. Why does this matter? For People: When companies walk the talk, people benefit through better working conditions, local job creation, and access to more ethical, healthier products. Trust builds loyalty. Transparent, credible action forges stronger relationships between businesses and the people they serve. For Profit: Sustainability isn’t a cost, it’s a growth strategy. Sustainable products grew 2.7x faster than conventional ones between 2015 & 2019. Over $30 trillion is now invested in ESG assets, and is expected to reach $40 trillion by 2030. For the Planet: The climate crisis is happening now. We need bold, credible action, not just pledges. Science-based targets, circular design, and effective net-zero strategies are essential. Turning Ambition into Action: At edenseven, we design, build, and implement sustainability strategies that deliver.
