CCSA supported and participated in a number of events across London Climate Action Week 2026. This page brings together the key sessions and activities we were involved in throughout the week.
Please note: This page serves as a recap of our CCSA Activities only.
London Climate Action Week 2026 took place from 20 June to 28 June.
CCSA was involved in several events across the week, including:
Tuesday 23 June
Reset Connect: Rebuilding Trust in Carbon Markets: Scaling Credible Offsets for Businesses
Olivia Powis, CEO, spoke on the Reset Connect panel “Rebuilding Trust in Carbon Markets: Scaling Credible Offsets for Businesses.” This session explored how businesses can scale credible carbon offsets and rebuild trust in carbon markets.
Corporate climate commitments are accelerating, but so is the scrutiny on the carbon markets meant to support them. Done right, high-integrity carbon credits can mobilise serious capital towards real climate action.
Olivia Powis, on a panel with Sotora Global, Cool Effect and Mitti Labs, set out how the voluntary carbon market is growing up, moving towards the governance, measurement and transparency that turn offsets into a credible tool for decarbonisation, not a reputational risk. This discussion explored stronger governance, better measurement nad verification, clearer claims frameworks and the emerging technologies bring fresh confidence to the market.

Ten years on: the future of UK-EU relations
As the postponement of the UK-EU summit was confirmed this week, Harry McWilliams, Senior UK External Affairs Officer, attended a recent UK in a Changing Europe and Flint Global event where Nick Thomas-Symonds MP, Minister for the Constitution and European Union Relations, reaffirmed that the next Prime Minister is expected to remain committed to Labour’s 2024 manifesto pledge for closer EU alignment, with ETS linkage continuing to be a stated priority area for delivery this year. We expect the Summit to be arranged for September.

Evening reception: ‘Resourcing the Future – Decarbonising the UK Waste Management Sector’
This private event brought key figures in the UK waste and resources sector together to chart a new course for cutting the carbon impact of managing the UK’s waste.
The event included discussion of the forthcoming Waste Sector Net Zero Transition Plan.

UK Green Business Awards
The CCSA team attended the UK Green Business Awards, where we were delighted to be shortlisted for Small Business of the Year. This recognition is testament to the hard work of the team and our members in supporting the commercial deployment of CCUS in the UK.

Super Pollutant Reception
Olivia Powis attended St James’s Palace on Wednesday for a Super Pollutant Reception as part of London Climate Action Week and the UK’s role as Co-Chair of the Climate and Clean Air Coalition.
The reception brought together international leaders from government, business, finance, philanthropy, academia and civil society around a shared message: tackling super pollutants is one of the fastest and most effective ways to slow near-term warming, while also strengthening economies, improving public health and protecting food systems.
Action on methane and other super pollutants could avoid up to 0.6°C of warming by 2050 while delivering immediate benefits for people and communities around the world.
Reflecting on London’s unusually high temperatures, Secretary of State Ed Miliband highlighted the urgency of action and the importance of collaborative action, including through the initiative to drastically reduce methane in the fossil fuel sector.
Building on the UN Secretary-General’s Call to Action on Methane launched the previous day, António Guterres described methane as the world’s “super super-pollutant” and called for faster implementation across fossil fuels, agriculture and waste.
Prime Minister Mia Mottley, Barbados reminded us that cutting super pollutants is one of the quickest ways to slow warming and noted the importance of targeting fossil fuel companies on this (and protecting vulnerable communities), whilst emissions reductions technologies are developed at scale protect vulnerable communities, President Murat Kurum – COP31 President – reaffirmed that methane reduction, zero waste and the circular economy will be central to an implementation-focused COP31.
In a conversation with the King, Olivia outlined the important role of CCUS and the progress that has been made in the UK to date – with the first two clusters in East Coast Cluster and HyNet – he was very supportive and also noted the important role of Utilisation of CO2, particularly in fertilisers.

Climate Crisis Advisory Group and UCL, with Sir David King – Carbon Removals in the Overshoot Era: Scale, Energy and the Path Forward
Mark Sommerfeld, UK Director, joined this closed-door roundtable exploring the role of carbon dioxide removals (CDR) in the overshoot era, with discussion focused on scale, energy requirements and the pathway for responsible deployment. Sir David King presented evidence on the volume of CDR needed to help limit global warming to around 1.6–1.7°C, estimated at 400–700 GtCO2 by 2100, while emphasising that removals must be delivered alongside rapid emissions reductions. The discussion considered how carbon removal technologies could scale, with Mark highlighting the importance of strong, predictable demand markets for CDR and the development of supportive CCUS infrastructure.

DAC to the Future 2026: Mission Zero
The event included an update on Mission Zero’s latest DAC technology developments, a lab tour featuring DAC in action, and a discussion on the future of DAC in the UK, including its role in supporting resilience in CO₂ supply chains. Mission Zero presented a new generation of its product and scalability priorities, including deployment in the UK through projects such as UnionDAC, alongside Progressive Energy and Airhive, and e-SAF Project Starling, alongside Carbon Neutral Fuels. Overall, critical opportunities for DAC to support the UK’s significantly constrained CO₂ supply were explored to utilise in low-carbon fuels production as well as the food, drinks and medical gases industries.
