Environment

Greenhouse gas (GHG) emissions are continuing to rise globally and in the region. GHGs come in a number of different forms and from multiple sources. Fossil fuel use is responsible for most global carbon dioxide (CO2) emissions, and a large part of global anthropogenic GHG emissions overall. Other GHGs – such as methane (CH4) – that also have significant potential to contribute to the overall challenges associated with climate change are mainly associated with agricultural activities and related land use changes. With average global CO2 concentrations in the atmosphere nearing 400 parts per million (ppm) and increasing by 2 ppm per year, urgent action is required to reverse the dangerous trend of rising GHG emissions of all types and sources.
