Within the United Nations Framework Convention on Climate Change, UNFCCC, efforts are underway to reduce greenhouse gas emissions and to increase the ability to adjust society to climate changes. International efforts to reduce emissions within the framework of the Kyoto Protocol are well known, but UN efforts regarding climate adaptation are not as visible. This report presents an overview of how the adaptation work efforts have been organised. In 2005, the Nairobi Working Programme (NWP) was started. This is a five-year programme under the UNFCCC that is intended to increase understanding about the effects of climate changes and spread information on how society can lessen its vulnerability by making adaptation measures. Ultimately, the NWP strives to help developing countries to make well informed, scientifically based decisions regarding climate related adaptation. There are nine sub areas within the framework of the NWP. One of these areas has to do with methods and tools that can be used to evaluate climate effects and vulnerability as well as making plans to adaptation. This report covers the work that has been done within this sub aea during the first half of the NWP, along with activities that are planned during the second half of the programme (until 2010). There is also a report from the UNFCCC expert meeting that was held in Mexico City, 3-7 March 2008, in the sub area methods and tools.
