Companies and professionals looking to manage sustainability goals and ESG risks have grappled with a variety of regulatory and policy changes in 2025. Regional fragmentation has emerged as U.S. states introduce their own climate disclosure rules while the Securities and Exchange Commission looks to reverse course on climate risk disclosures at the federal level, and the European Union works to simplify its landmark corporate sustainability disclosures.
Sustainability executives navigating this uncertainty will continue to look to their peers and industry leaders to share insights that can aid decision-making at their own organizations. As the calendar of events for 2026 begins to take shape, early agendas focus on navigating policy turbulence and the ongoing energy transition, as well as focusing on advancing circularity and decarbonization. Artificial intelligence — both in terms of its energy resource needs and potential sustainability applications — also remains a hot topic.
Here are some of the notable ESG and sustainability conferences that are already scheduled for 2026.

UN 2026 Climate Change Conference (COP31)
November
Australia or Turkey
The United Nations’ annual climate change conference for 2025, COP30, has yet to take place in Brazil, and it’s still up in the air where global policymakers will convene in 2026. Australia and Turkey have both been bidding to hold the conference, and there’s been recent reports of a potential compromise co-hosting bid. Regardless of where COP31 takes place, it is likely to happen without the United States’ involvement, as President Donald Trump pulled the U.S. from the Paris Agreement and several international cooperation initiatives on climate change broadly.
