The climate crisis is not in the future; it is already here, hitting the most vulnerable: poor countries, forest peoples, river communities, slum dwellers, and rural populations who suffer from floods, droughts, and extreme temperatures. These people, who contributed the least to the problem, are paying the highest price. While the planet collapses, the richest continue to accumulate their fortunes, shielded in their bubbles. This proposal is based on the studies of Esther Duflo and Gabriel Zucman, economists whom the Brazilian government has taken as a reference to move forward in the G20 debate. It is absurd that this hasn’t advanced yet. A 2% wealth tax on 3,000 billionaires could fund much of the climate adaptation for over half of the world's population! The urgency is real, and the G20 will be the perfect stage for this change, with the world's most powerful leaders gathered. But we have little time because negotiations for the final meeting text began on 22 October 2024! That's why we need to be many voices. Together, let’s pressure the 20 global leaders and demand that the climate crisis be addressed in a fair and just way. What is the G20? The G20, also known as The Group Of Twenty, is the premier forum for international economic cooperation comprised of 19 countries ((Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Türkiye, United Kingdom and United States) and two regional bodies: the European Union and the African Union (as of 2023). It plays an important role in shaping and strengthening global architecture and governance on all major international economic issues [1]. Currently, Brazil holds the G20 Presidency. Previously, India held the Presidency from 1 December 2022 to 30 November 2023. On 1 December 2024, South Africa will officially take over the G20 Presidency until November 2025, making it the last country in the Global South to hold the presidency.
