Climate change is a global environmental threat that will have increasingly undesirable effects around the world in our lifetimes. International negotiations to limit the emissions of long-lived greenhouse gases (GHG) have stalled. There is a very real possibility that current emissions of GHG have already committed the world to “dangerous anthropogenic interference with the climate system”. There are, however, cooperative initiatives to reduce methane. Methane is a powerful short-lived greenhouse gas (approximately 20 (50) times as potent as carbon dioxide over 100 (20) years with lifetime of about 12 years) that also contributes to the formation of surface ozone that harms human health, agriculture and ecosystems. The Global Methane Initiative (GMI, http://www.globalmethane.org/index.aspx) is a partnership of over 40 countries, including the US, China and India, that are high emitters of methane. The partners work together to facilitate methane capture and use projects primarily in five areas: agricultural sources, municipal solid waste (landfills), coal mines, oil and natural gas systems, and municipal wastewater systems. In addition, a new international initiative called the Climate and Clean Air Coalition to Reduce ShortLived Climate Pollutants (CCAC, http://www.unep.org/ccac/) currently has 17 country partners including the US. The goal of CCAC is “to protect human health and the environment, and slow the rate of near-term climate change, by catalyzing rapid reductions in [methane, black carbon and HFCs]”. The workshop’s task is to develop creative yet realistic, well-reasoned and supported policy recommendations that describe feasible domestic and international actions that will rapidly and cost-effectively reduce methane emissions both at present and in the future.
