Greenhouse gas (GHG) emissions are the major driver for climate change, the most important challenge facing society globally.
At the Paris Conference of Parties (COP) meeting in 2015, 196 countries agreed on measures to mitigate impacts from the globally observed temperature increase and resulting adverse impacts. The measurement of GHG emissions is therefore an important step in understanding how emissions affect climate change; identifying hot spots where significant GHG emissions occur; measuring efforts in reducing GHG emissions and their contribution to climate change mitigation.
