What is Climate Diplomacy?

The climate crisis is one of the greatest challenges of the 21st century – the geopolitical consequences are substantial. As things stand, we are on course for a much warmer world. The repercussions for our foreign policy agenda are significant and therefore a stronger role for foreign policy in international climate policy is called for – namely through climate diplomacy.

Who we are

adelphi and the German Federal Foreign Office first formed an alliance over a decade ago and have since been playing a central role in the process of analysing the international debates on climate diplomacy and security, while developing key narratives, contributing to awareness raising and capacity building efforts, and supporting international and regional dialogues on this topic around the world.

Policy Analysis and Reseach

Conducting policy analysis and research, and compiling concise policy briefs to inform key policy actors, lies at the heart of the Climate Diplomacy Initiative. Discover a series of climate diplomacy policy briefs, flagship reports and climate security and fragilty risk assessments.

Expert Dialogues and Consulations

The security consequences of climate change will be different in each continent and will interact with social, political and economic processes and capabilities that are unique to each region. Regional dialogues provide a forum for local partners and experts to exchange views and network.

Capacity Building

In order to formulate appropriate policies and sound long-term strategies, as well as to conduct climate outreach, a thorough grasp of climate diplomacy, and an understanding of the characteristics of climate impacts and politics in each region are necessary. Discover our trainings and briefings.

Knowledge Management and Outreach

One key strategic objective of the Climate Diplomacy Initiative is to engage the wider public in the debate around climate diplomacy. To that end, adelphi and the German Federal Foreign Office have devised an integrated communication concept for multiple target groups.
