​30 Years, One Planet: A Pre-COP Dialogue on the Road to Belém

​As the world prepares for COP30 in Belém, Brazil, this year marks 30 years since the first UN Conference on Environment and Development (the Rio Earth Summit) — a pivotal moment that shaped the global climate agenda.

​Three decades later, the urgency of climate action has only deepened, while the frameworks, institutions, and public expectations around climate governance have evolved in complex ways.

​“30 Years, One Planet” invites participants into an open and engaging pre-COP dialogue to explore where we’ve come from and where we’re headed next.

​Through this session, we’ll look back at 30 years of international climate negotiations and look forward to what’s at stake in COP30 — the first COP to be hosted in the Amazon region.

​Join us for this dialogue hosted by Sustainability Community Finland, as we reflect on thirty years of global climate action and look ahead on the road to Belém.
