Measuring Climate-related Aid


OECD-DAC is gathering statistical data on climate change-related aid. This is done through "Climate Mitigation Marker" and "Climate Adaptation Marker". This is a unique statistics that tells how much climate-related ODA is spent on what activities, by what country, and to what country.


In general, the data becomes available at the end of next year. For example, the data on 2011 normally becomes available at the end of 2012 or early 2013.  Also note that data on climate adaptation is available only from 2010 flow.
