From AI regulation to new nature funds: Key announcements from LCAW 2026

London Climate Action Week 2026 brings new finance tools and AI frameworks

London Climate Action Week wrapped up on 28 June 2026 after eight days of sessions, announcements and policy debates. Now in its eighth year, the event has become Europe’s largest independent climate gathering. This year brought over 150 speakers and more than 40 sessions focused on moving climate work from planning into practice.

The week covered four main areas: building the clean economy, making climate transitions fair, growing professional networks, and scaling finance for nature projects. Bloomberg Philanthropies and Bloomberg L.P. anchored the event, while the London Stock Exchange Group hosted several major launches. Organisations including C40 Cities and the Climate Innovation Forum ran sessions throughout the week.

For UK businesses, the week offered concrete examples of how companies are tackling emissions in supply chains, using new credit risk models, and funding nature restoration. Several announcements directly affect how businesses approach carbon reporting, procurement decisions, and financial planning. The timing was notable: the Met Office issued an extreme heat warning for London during the event, adding immediate context to discussions about climate resilience.

Major sessions covered AI regulation and supply chain emissions

On 24 June, a panel examined how artificial intelligence can support electrification programmes. The session looked at regulatory approaches for AI systems in energy infrastructure. This matters because businesses investing in electric fleets or building upgrades need to understand how AI tools will be governed and how that affects procurement decisions.

The same day, Lindsay Hooper delivered a keynote on UK retail sector collaboration to address Scope 3 emissions through to 2030. Scope 3 covers indirect emissions in a company’s value chain, typically the largest portion of a business’s carbon footprint. For retailers, this includes everything from product manufacturing to customer use and disposal. The session outlined how competitors are sharing data and methods to tackle these emissions collectively.

On 25 June, HSBC ran a session on resilience-adjusted credit risk. The bank presented methods for incorporating climate risks into lending decisions. This development affects businesses seeking finance, particularly those in sectors exposed to physical climate risks or transition costs. Lenders are increasingly factoring climate resilience into creditworthiness assessments.

Also on 25 June, Jie Zhou presented on scaling transition and nature finance. The session moved from theoretical frameworks to actual deployment of capital into nature-based projects. Nature finance typically funds activities like habitat restoration, sustainable forestry, or marine conservation. These projects can generate carbon credits or biodiversity net gain units that businesses need for compliance or voluntary commitments.

The London Stock Exchange Group hosted the launch of model guidance on climate transition plans from the United Nations Sustainable Stock Exchanges Initiative. The guidance provides listed companies with a framework for developing and disclosing transition plans. In addition, LSEG hosted the World Climate Investment Summit, which brought together institutional investors to discuss climate-related investment strategies.

Extreme heat warning reinforced discussions on climate adaptation

The Met Office issued an extreme heat warning for London during the event week. Temperatures reached levels that disrupted transport and affected outdoor activities. This provided immediate evidence of the climate impacts being discussed in sessions about resilience and adaptation.

Businesses operating in London faced practical decisions about employee safety, building cooling, and service continuity. The heat event demonstrated why resilience planning matters for operations, not just long-term strategy. Companies without adequate cooling systems or flexible working arrangements experienced direct impacts on productivity.

The timing highlighted a gap many UK businesses still face: climate strategy documents often focus on emissions reduction but lack detail on adapting to physical climate risks. Heat events, flooding, and supply chain disruptions from extreme weather require different responses than carbon reduction programmes. Several sessions during the week addressed this gap, examining how businesses can build resilience into infrastructure, supply chains, and financial planning.

What UK businesses should understand from the week’s announcements

The retail sector’s collaborative approach to Scope 3 emissions offers a model for other industries. Many businesses struggle with supply chain emissions because they lack direct control over suppliers or customer behaviour. However, the retail sessions showed how sharing methodologies, engaging suppliers collectively, and setting common standards can reduce costs and improve data quality. This approach may spread to other sectors where Scope 3 emissions dominate carbon footprints.

HSBC’s work on resilience-adjusted credit risk signals a shift in how banks assess loans. Businesses in high-risk sectors or locations may face higher borrowing costs or stricter lending terms. Consequently, companies should consider climate risks when planning capital investments or refinancing. Properties in flood zones, facilities dependent on water-intensive processes, or supply chains exposed to extreme weather all affect credit assessments.

The nature finance sessions revealed growing availability of funding for projects that combine carbon sequestration with biodiversity benefits. UK businesses with land holdings or those developing offsetting strategies should understand how nature-based solutions fit into their carbon plans. Furthermore, companies bidding for public sector contracts may find that nature-positive commitments become a differentiator as procurement policies evolve.

AI regulation in the energy sector will affect businesses investing in smart building systems, electric vehicle charging infrastructure, or renewable energy. As regulatory frameworks develop, companies need clarity on data governance, liability for AI decisions, and interoperability standards. The LCAW sessions indicated that regulators are working on these frameworks now, which means businesses should engage with consultations rather than waiting for final rules.

The focus on fair transitions carries commercial implications. Policies that support workforce retraining, regional development, or consumer affordability often come with business obligations. Companies may face requirements to report on social impacts, engage with affected communities, or contribute to transition funds. Understanding these expectations early helps businesses plan budgets and stakeholder engagement.

How these developments affect business planning and procurement

Businesses preparing carbon reduction plans should examine the retail sector’s collaborative approach to Scope 3. Instead of trying to tackle supply chain emissions alone, companies can join industry initiatives that share data and engage suppliers collectively. This reduces costs and improves the quality of emissions data. For procurement teams, this means seeking out sector collaborations and understanding which suppliers participate in shared reporting frameworks.

Companies seeking finance need to assess how climate risks affect their creditworthiness. HSBC’s work on resilience-adjusted credit risk shows that lenders are developing sophisticated models to factor physical and transition risks into lending decisions. Businesses should conduct their own climate risk assessments before approaching lenders, identifying vulnerabilities in facilities, supply chains, and markets. This preparation can help secure better terms and demonstrates management competence to investors.

The nature finance sessions revealed opportunities for businesses with land holdings or those developing offsetting strategies. Projects that restore habitats, improve soil health, or protect water sources can generate revenue through carbon credits or biodiversity net gain units. However, these projects require long-term commitments and verification processes. Businesses should investigate which nature-based solutions align with their carbon targets and whether they have suitable land or partnerships to pursue these projects.

AI regulation in the energy sector will affect procurement decisions for businesses investing in building management systems, electric vehicle infrastructure, or renewable energy installations. As frameworks develop, companies should prioritise systems that comply with emerging data governance standards and interoperability requirements. Working with suppliers who engage in regulatory consultations reduces the risk of choosing systems that become non-compliant.

The emphasis on fair transitions means businesses should consider social impacts alongside environmental targets. This includes workforce planning for changing skill requirements, engagement with communities affected by facility closures or expansions, and affordability considerations for customers. Public sector procurement increasingly values these factors, so businesses bidding for contracts should document their approach to fair transitions.

For companies preparing transition plans following the UN guidance launched at LSEG, the key elements include clear targets, credible pathways to achieve them, governance structures, and disclosure of progress. Transition plans increasingly affect access to capital markets, major contracts, and investor confidence. Therefore, businesses should treat transition planning as a core strategic exercise rather than a compliance task.

Where to find authoritative guidance and updates

The United Nations Sustainable Development website provides access to the model guidance on climate transition plans launched during LCAW. This includes frameworks for developing credible transition plans and disclosure recommendations.

The Met Office publishes climate projections and extreme weather warnings relevant to UK businesses assessing physical climate risks. Their guidance helps companies understand regional vulnerabilities and plan appropriate adaptations.

The Department for Energy Security and Net Zero sets policy on energy regulation, including frameworks that will govern AI applications in energy systems. Businesses can access consultations and policy updates through the department’s website.

The C40 Cities network ran several Action Agenda initiatives during LCAW and provides resources on urban climate action. Companies operating in cities should understand municipal climate policies through C40 resources and local authority climate action plans.

What this means for UK businesses over the next 12 months

The announcements and frameworks presented at LCAW 2026 will shape business requirements through 2027. Companies should review their carbon reporting to ensure Scope 3 emissions receive adequate attention, particularly in supply chains. Joining or monitoring industry collaborations on Scope 3 can reduce costs and improve data quality compared to isolated efforts.

Businesses planning capital investments should conduct climate risk assessments before approaching lenders. Understanding how resilience-adjusted credit risk affects borrowing terms allows better financial planning. Similarly, companies should assess which assets or operations face the highest physical climate risks and prioritise adaptation measures for those areas.

For organisations developing transition plans, the UN guidance launched at LSEG provides a credible framework. Investors, customers, and regulators increasingly expect detailed transition plans with clear targets and governance. Starting this work now gives businesses time to engage stakeholders and develop credible pathways before disclosure requirements tighten.

Nature-based solutions are moving from niche projects to mainstream carbon strategies. Businesses should investigate whether nature finance aligns with their emissions reduction targets and whether they can access suitable projects through land holdings or partnerships. Early movers in nature finance may secure better project opportunities and pricing.

AI regulation in the energy sector will develop rapidly over the next year. Companies investing in electrification or smart energy systems should monitor regulatory consultations and choose suppliers who demonstrate compliance readiness. Waiting for final regulations before considering these issues may leave businesses with non-compliant systems requiring costly retrofits.

Climate resilience planning deserves equal attention to emissions reduction. The extreme heat during LCAW demonstrated that physical climate risks affect operations immediately, not just in future scenarios. Businesses should assess vulnerabilities in facilities, supply chains, and workforce arrangements, then develop practical adaptation measures.
