This is a summary of the IFRC guide on climate-smart programmes and humanitarian operations (Climate Centre and IFRC, 2023). The guide supports National Red Cross and Red Crescent Societies and the IFRC in making their programmes and operations climate-smart. It is filled with examples, resources and tools that can be applied easily to make our work climate smart. This shorter version distils the key concepts, messages and components of the longer guide and refers to relevant sections where further ‘how to’ information can be found.
