COP30

Bringing citizens to the
heart of climate negotiations

The power to drive climate action lies with all of us

In 2025 the Brazilian government is placing the Global Citizens’ Assembly (GCA) at the heart of COP30.

Designed to mobilise millions of people to influence climate negotiations, hold leaders accountable, and build a permanent legacy

With trust in governments at an all-time low—only 39% of people across G20 countries
believe their leaders will act in their best interests—citizen participation has never been more
urgent.
