Development and Climate Days 2025 (D&C Days 2025) is an annual event that bridges the issues of climate change and development. Held annually alongside the UNFCCC conference, it fosters dialogue and knowledge sharing between the climate change and development communities, providing a platform for leaders and practitioners to discuss strategies for a more sustainable and resilient future.  

On Thursday 30 October we invite you to join us for a day of online dialogue, interaction, difficult conversations and solution-focused sessions, bringing together climate thought leaders to discuss the real issues that we should be tackling at COP30.

D&C Days will bring everyone together online in advance of the climate negotiations to create a set of key messages and asks which can be taken to COP30 to help influence climate decisions – recognising the most vulnerable people and Parties at the front lines of climate change.  

This digital approach ensures that D&C Days is accessible to practitioners, negotiators, scientists and policymakers worldwide – even those who are unable to attend COP30 in person. 

Following the online event, we will host an in-person reception at The Resilience Hub on 15 November during COP30 in Belém, Brazil to highlight these messages with UNFCCC experts and negotiators. More information coming soon. 

D&C Days 2025 will concentrate on climate actions across three key areas: 

• Scaling locally led approaches to climate action
• Financing resilience
• Innovation for transformation 

D&C Days isn't just another COP event – it's a powerful catalyst for change. By bringing together voices from around the globe ahead of COP30, we're creating a unique opportunity to unite, collaborate, and amplify the urgent needs of those on the climate frontlines.

This year’s event is organised in partnership by the International Institute for Environment and Development (IIED), the Red Cross Red Crescent Climate Centre (RCCC), DanChurchAid, the Global Resilience Partnership (GRP) and the Wellcome Trust, with additional support from the Ministry of Foreign Affairs of the Netherlands via the Generating Ambition for Locally-led Adaptation (GALLA) programme.
