A new chapter for climate action

In this decisive decade, governments, businesses, and communities from across the world have the opportunity to define a new chapter for climate action. With global temperatures expected to temporarily rise beyond 1.5°C in the next five years, amid worsening climate extremes, the COP 28 ‘Global Stocktake’ offers a critical chance to reset. The path forward must include radically strengthened efforts to reduce emissions, build resilience, address loss and damage, and mobilize climate finance. New partnerships, financing mechanisms and innovative approaches to harness public and private sector collaboration will be crucial to deliver on our global climate goals and protect biodiversity. We have the means to drive significant transformative change and we must now seize the moment to accelerate progress.

Ahead of COP 28, this annual conference will gather senior leaders and decision-makers from the business community, multilateral organizations, government agencies, policymakers, academia and non-governmental organizations. Two days of high-level panel dialogues, networking sessions and interactive workshops under the Chatham House Rule will focus on multi-stakeholder collaboration for increased ambition, action and impact.

This year’s conference will be convened in-person at Chatham House and simultaneously broadcast on our LIVE event virtual platform.

Why attend?

  • Understand the key themes of the COP 28 agenda and the geopolitical developments shaping the future of climate diplomacy and finance.

  • Discover innovative approaches, actionable steps and collaborative solutions to accelerate the climate transition.

  • Explore the growing role of nature-based solutions to tackle the climate crisis, resource scarcity, environmental degradation and biodiversity loss.
