## Chapô
**10 Years after the Paris Agreement, watch this in-depth discussion on the legacy of COP21 and the Paris Agreement with Todd Stern, Laurence Tubiana and Sébastien Treyer, chaired by Charlotte Halpern. This debate highlighted both the successes and challenges of multilateral climate action. While the Paris Agreement remains a historic achievement, its implementation faces political, financial, and geopolitical hurdles. Future progress will depend on public engagement, political pressure, and creative approaches to finance and diplomacy.**

## Corps du texte
**Key Takeaways:**

*   **The Need for Public Buy-In:** Winning public support is as important as winning policy debates. Disinformation and political polarisation must be countered, and climate policies must be framed as benefiting all citizens and not just an elite agenda;
*   **Governments Must Feel the Pressure:** History shows that political leaders act when they believe inaction will cost them politically. Climate movements must increase pressure on governments;
*   **Brazil’s Key Role in COP30:** With Brazil hosting COP30 in 2025, the country has a unique opportunity to restore trust between developed and developing nations. Climate finance will be central, and Brazil must start negotiations early to ensure meaningful outcomes;
*   **Reforming Climate Finance Is Crucial:** Both Todd Stern and Laurence Tubiana stressed that today’s international finance system is insufficient. They pointed to proposals such as reforming multilateral development banks to unlock large-scale funding, introducing global levies on shipping or fossil fuels, and phasing out fossil fuel subsidies — still worth nearly $1 trillion a year.
