Executive Summary

Climate Week NYC will return September 20–27, 2026, bringing more than 1,000 events to New York City alongside the United Nations General Assembly. Organized by Climate Group, the eight-day gathering will connect business executives, government officials, investors, community leaders, and climate specialists across 12 program themes. The Opening Ceremony is scheduled for Monday, September 21, followed by two days of flagship programming at The Hub Live. Under the organizing message “Energy. Impact. Action.,” this year’s event will emphasize implementation, economic competitiveness, resilient infrastructure, and the transition to cleaner energy systems.

Rising Electricity Demand Moves to Center Stage

The 2026 agenda arrives as electrification, artificial intelligence, data centers, industry, and extreme heat place increasing pressure on electricity systems. Organizers are positioning energy security and grid modernization as central business and policy challenges, with discussions expected to examine permitting delays, infrastructure constraints, supply-chain pressures, clean-technology costs, and access to affordable and reliable power. Featured programming includes sessions on how AI-related demand affects grid capacity and how sustainable infrastructure can support technological growth without slowing climate progress.

Twelve Themes Expand the Implementation Agenda

The official Events Program is organized around Buildings and Infrastructure; Climate and Health; Energy and Electrification; Environmental Justice; Finance and Clean Growth; Food and Agriculture; Industry and Supply Chains; Nature, Land and Oceans; Policy, Governance and Leadership; Sustainable Living, Cities and Communities; Technology and AI; and Transport and Travel. Adaptation and resilience, education, youth leadership, and the just transition will run across the 12 themes. This structure broadens the week beyond emissions reduction to include physical climate impacts, public health, resilient housing, water infrastructure, food security, insurance, community preparedness, and sustainable finance.

Flagship Sessions Connect Policy, Capital, and Delivery

The September 21 Opening Ceremony will feature senior leaders discussing how to accelerate climate and economic progress. The Hub Live will continue on September 21 and 22 with three flagship plenary sessions and dozens of breakouts, side events, and executive roundtables. The wider calendar includes public and private events delivered in person, online, and through hybrid formats. For organizations applying Climate Business Intelligence™, sessions covering infrastructure, finance, cities, supply chains, health, and adaptation provide opportunities to connect forward-looking physical hazard analysis with investment, capital planning, operational resilience, and public policy.
