Defined as the biggest challenge of our century, climate change is and will increasingly affect the work of National Red Cross and Red Crescent Societies and other humanitarian organizations. Amongst others, some of its most direct impact are reflected in increased climate variability (already experienced in several parts of the world) and in the rising number and intensity of hydro-meteorological hazards. These trends, together with a worldwide rise in vulnerability levels call for greater investments in addressing current and future risks, enhancing community resilience and their coping capacities. At a time when current resources are already stretched, National Red Cross and Red Crescent Societies have expressed the need to gain better understanding of how to access existing climate funds that will enable them to mainstream climate change in their programmes. This document aims at providing National Red Cross and Red Crescent Societies with an overview of some dedicated funding sources for climate change. The guide also provides some basic information on how to access these funds.Published in 2013.
