From ambition to implementation: five takeaways from New York Climate Week 2026
Last week policymakers, leaders and activists met in New York for this year’s Climate Week (NYCW). Now recognised as a key marker in the climate policy calendar, this NYCW saw new projects announced, partnerships, and coalitions set up over the 1500 events which took place.
This year, the conversation moved from target-setting and ambitions, to planning the concrete delivery of action and the practical systems needed to scale solutions. It marks a crucial discussion opportunity in the build up to COP31 in November, which has been framed as the ‘Implementation COP’. Across reoccurring themes; resilience, energy efficiency, collaboration, electrification and AI, the message remained that the time for talking is over, we must now set out a plan of action.
Ambition to Action
This year’s NYCW saw city, regional and national leaders speaking about adaptation, resilience and action, with a key message. The time for debating the direction of climate action and raising ambition has passed. The solutions exist, and they must be turned into delivery, at speed and at scale.
During the week, there were several announcements of practical action. Nigeria set out plans for a $300 million clean energy fund, while New York Mayor Zohran Mamdani announced a greener homes plan and secured funding for cooling points to protect outdoor workers from extreme heat.
Meanwhile, Catalonia joined the sub-national methane coalition (SMAC), becoming the 37th state or regional government to commit to cutting methane emissions. Methane is responsible for a third of the rise in global temperatures and reducing emission is one of the most immediate opportunities to slow temperature rise.
These announcements demonstrate how climate ambition can translate into action across different sectors and levels of government. The challenge will be to turn individual commitments into sustained progress.
Electrification and scaling energy solutions
Electrification was another recurring theme, with discussions highlighting the need to accelerate the transition towards cleaner energy. The International Energy Agency’s Fatih Birol described the world as “entering the age of electricity”, while emphasising that the pace of progress must increase.
Business leaders made the case for electrification as more than simply an environmental responsibility. On a panel discussion about efficiency and electrification, Hannah Hislop, Head of Sustainability at Unilever, said the business case for climate action is now impossible to ignore. Energy efficiency and decarbonisation are already making real impacts on emissions reduction but can also help companies build market resilience by foreseeing consumer demands.
Within transport and industry, this is clear with the case of electric cars. Ethiopia banned combustion engine imports two years ago, thereby mitigating transport emissions by creating a spike in demand for electric vehicles and reducing the need for fossil fuel imports.
AI dominated discussions
However, in energy technology, and increasingly with AI, the issue of regulations and safeguards became apparent. Artificial intelligence was prominent throughout the week, with discussions exploring both its limited potential to support climate action and the risks associated with its rapid expansion.
AI can help organisations improve data quality, identify climate risks, optimise buildings and fleets, and make sustainability reporting more efficient. However, these benefits must be weighed against the environmental pressures created by growing demand for data centres.
Globally, the International Energy Agency estimates that data centres consume over 560bn litres of water annually, placing further strain on what the UN termed earlier this year an ‘era of global water bankruptcy’. As with ‘big tech’ owners, it is understood that COP31 will be inundated with AI lobbyists and apologists, which may cause conflicting interests to delay progress despite a strong message for transparency from the Turkish President and COP organisers.
While accountability for the AI sector is good considering the extreme growth during the past few years, the way AI is drawing attention is concerning to CAFA. Every time AI is the topic of a conversation, it diverts attention away from the bigger issues: fossil fuel use and livestock, responsible for more than 80% and 12-19.6% of global greenhouse gas emissions, respectively. Even when it’s mentioned as a solution, it risks diverting attention from electrification, low carbon energy, nature restoration and conservation, dietary change, and circular practices avoiding primary production.
That said, companies falling behind on their net zero targets need to be held to account. Companies driving new gas-fired generation or increasing their emissions include Meta, xAI, Google and Microsoft. Some have committed to cutting data centre emissions in the future, but their emissions continue to rise. Such pledges – words on paper - don’t compensate for missed targets, increased physical emissions and fossil fuel lock-in. Real action is expected instead of pledges, as pressure mounts to move from commitments to actual emission cuts.
Resilience as a theme among positive actions
An underlying theme across the week was building resilience. Extreme heat featured prominently, particularly in conversations about urban resilience. City leaders who form part of the C40 Cities for Climate Leadership explored measures that would decrease the impacts of climate risks, on citizens and the workforce.
The Boston Mayor Michelle Wu led by example, rolling out training placements for 4500 green jobs to build a resilient workforce. In Miami, plans for new heat sensors were announced, which would trigger a week before extreme temperatures hit, giving time to lay out a range of measures and contingency plans. Evidence suggests that countries with robust early warning systems experience nearly six times fewer disaster-related deaths. These examples highlight the importance of preparing for climate impacts that are already being experienced. For businesses, resilience means looking beyond emissions reduction to also consider how locked-in or likely extreme weather will affect employees, supply chains, infrastructure and operations.
Collaboration leads to action
The most consistent message throughout Climate Week was that no organisation can deliver the transition alone. Speaking in the opening address last Monday, UK Foreign Secretary (previously Energy Secretary) Ed Miliband stated that: "No country can tackle the climate crisis alone. We can only solve it together.”
Mithika Mwenda, Pan African Climate Alliance Leader, also made an important speech on collaboration. He said “nobody can work in isolation, rich or poor, leader or community member, and trust has to be built first to allow action”. It is now the time to look to our community, including suppliers, peers, and networks to continue learning and coordinate action. New York Climate Week has offered new and exciting examples of real action which can help lead the way
CAFA events during NYCW
During the week CAFA and the Science Based Targets initiative (SBTi) came together for a deep dive into the Corporate Net-Zero Standard V2.0, helping organisations understand the standard for setting credible climate targets and answering questions about implementation. This was followed by a roundtable discussion, organised with the Can Manufacturers Institute, the Recycled Materials Association, and The Recycling Partnership on how circular economy principles can begin to shape actions for member organisations. We discussed the role of the consumer, and how communications can be an important part of a sustainability message.
On Thursday 24th, we organised two sessions of our Member Meetups – a monthly event for associations around the world, member to the CAFA collective, to connect with peers and learn from experts. We welcomed the Insurance Council of Australia, Climate Trunk, the Recycled Materials Association, and the Cosmetic, Toiletry and Perfumery Association for insights on sector sustainability and engagement strategies - join CAFA to attend the next sessions in October.
As the focus shifts from ambition to implementation, associations are uniquely positioned to turn shared ambition into collective action. By bringing members together, sharing practical knowledge and showcasing what is already working, they can help businesses move from setting targets to meeting them.
