NEW YORK

International climate leaders converge in New York from Sept. 20 to 27 for the United Nations General Assembly, marking a stark shift in priorities: affordability now rivals climate ambition on the agenda.

The timing is no accident. An escalating war in Iran has spiked energy costs globally. The artificial intelligence boom is driving massive spikes in power demand. And with midterm elections approaching, U.S. policymakers face a political reality—voters won't accept climate action that empties their wallets.

ICLEI, the international coalition of local governments driving climate policy on the ground, is bringing more than 15 mayors and officials from the United States, Brazil, Kenya, the Philippines, Albania and Mexico. Their mandate: reshape the climate agenda for next year's COP31 conference in Turkey and accelerate transitions at home.

A Sept. 19 session titled "Urban planning for a changing climate" will feature municipal leaders discussing how to relocate people and critical infrastructure away from high-risk areas—and how to pay for it. The event, hosted at The Penn Club by ICF, ICLEI USA and the National League of Cities, will confront the hard questions communities face in funding these programs.

Former Vice President Al Gore will anchor the week with a Sept. 20 discussion, "An Inconvenient Truth: Then and Now," reflecting on two decades of climate policy and the obstacles ahead.

The California Climate Leadership Forum, also running this week, will drill down on how to integrate emissions cuts with economic growth and community resilience—acknowledging that climate policy cannot be divorced from pocketbook concerns.

New York City's approach to climate budgeting offers one model: distributing costs across multiple city departments to spread the financial burden while advancing emissions reductions. The strategy recognizes a political truth: climate action embedded into routine municipal operations faces less resistance than standalone initiatives.
