Through the GCCA and geographical programmes, the EU provides assistance for climate change across the world with a special focus on LDCs and SIDs. The EU is thriving to make climate change support effective, helping government partners to integrate climate change into national development planning and budgeting and piloting budget support. In doing so, it ensures full alignment with country's strategies and systems and long-term institutional strengthening. Through this focus, the EU is also helping countries increasing their absorptive capacities and preparing to receive long-term climate change finance, paving the way for long-term climate compatible development. It also serves as catalyst to further integrate climate change into EU regular development aid, thereby creating a multiplier effect. As the future of the GCCA is being shaped, the side event will bring to the table voices from developing countries on early results, lessons learned and priorities for the next years.
