Workshop on common metrics to calculate the CO2 equivalence of anthropogenic greenhouse gas emissions by sources and removals by sinks


01:00 - 00:59


UN Campus, Langer Eugen





3 – 4 April 2012
UN Campus, Langer Eugen (Room 1916), Hermann-Ehlers-Str. 10
Bonn, Germany


The Subsidiary Body for Scientific and Technological Advice (SBSTA), at its thirtieth session (2009), initiated its consideration of common metrics to calculate the carbon dioxide equivalence of anthropogenic greenhouse gas emissions by sources and removals by sinks.

The SBSTA at its thirty-fourth session (2011) requested, the secretariat to organize, subject to the availability of resources, a workshop on common metrics, to be held in the first half of 2012, with a focus on four major areas: i) uncertainties; ii) new and refined areas or metrics; iii) policy goals; and iv) relationship between policy frameworks and metrics, with the purpose of providing information for further consideration of the SBSTA at its thirty-sixth session (2012).
