Last week’s Rio+20 conference failed to yield strong sustainability commitments from corporations. The gap between where we need to get to avoid climate change’s worst effects and the actions companies are willing to take to get us there have never been further apart.

Companies around the world are increasingly measuring and managing their greenhouse gas (GHG) emissions in response to drivers like consumer preference, purchaser demands, and sustainability goals.

GHG accounting is not a static field and the GHG Protocol is constantly reviewing its publications to ensure they properly reflect the science on climate change and continue to define best practices for GHG accounting and management. One area the GHG Protocol monitors is the best available scientific evidence regarding the importance of individual GHGs, as evaluated by the Intergovernmental Panel on Climate Change (IPCC) and as reflected in the guidelines of the United Nations Framework Convention on Climate Change (UNFCCC) for national GHG emissions reporting.
