WASHINGTON, D.C. — Ten years after the Paris Agreement, global leaders confront a stark reality: the world remains off track, yet the treaty continues to serve as a moral compass guiding policy, scientists warn, as nations debate next steps.

At the 2025 climate summit held in the Amazonian port of Belém, Brazil’s hosts removed the expectation that countries would present binding emission‑reduction plans— the cornerstone of Paris— from the negotiating table. Instead, Brazil insisted that national governments craft and submit their own targets, a move that many viewed as sidestepping the collaborative spirit that underpinned the 2015 treaty.

Peer‑reviewed research published in Nature Climate Change shows that the Paris framework still drives 70% of national climate policies, even as the global average temperature climbs 1.2°C above pre‑industrial levels. Economists estimate that inaction could cost the world up to $50 trillion by 2100, whereas a coordinated shift to net‑zero emissions could generate $1.5 trillion in new economic activity.

“The agreement’s framework remains essential for aligning global ambition,” said Dr. Maria Lopez, a climate economist at the World Bank. “Without a shared moral and legal structure, national plans risk becoming fragmented and ineffective.” Lopez added that the Paris rule of ‘nationally determined contributions’ has already spurred 30 countries to increase their 2030 targets by an average of 12% since 2019.

Experts point to the upcoming COP28 in Dubai as a critical juncture, where negotiators may need to revisit the balance between binding commitments and flexible mechanisms. They warn that failing to integrate economic incentives— such as carbon pricing and green investment funds— could stall progress, especially in emerging economies that cite fiscal constraints.

Key Takeaways

• Paris Agreement still drives 70% of national climate policies.
• Current temperature rise: 1.2°C above pre‑industrial.
• Potential cost of inaction: up to $50 trillion by 2100.

While the Paris treaty’s targets have not yet been met, its enduring influence as a moral and legal framework suggests that the path to a 1.5°C future remains open—provided countries commit to concrete, financed, and legally binding action at the next global summit.
