The Task Force on Short-Lived Climate Forcers produced the "Progress Report and Recommendations for Ministers", which was a mayor deliverable during the Danish Chairmanship and approved by ministers at the Nuuk Ministerial Meeting on 12 May 2011. In addition the task force produced a supporting technical document. The technical report contains some technical changes that have been made since the Nuuk Ministerial. The task force was established with the 2009 Tromsø Declaration and focused initially on black carbon. The Task Force was requested to continue its work on short lived climate forcers and focused on methane and tropospheric ozone, as well as further black carbon work where necessary and provided a report to the Kiruna Ministerial Meeting in 2013.
