In order to achieve the Paris Agreement goal of holding the increase in global mean temperature at well below 2 °C, relative to pre-industrial levels, and pursue efforts to limit warming to 1.5 °C, every single effort resulting in GHG emission reduction or contribution to SDGs should be measured/monitored and reported. While a number of efforts will take place at national level, led mainly by the government, a number of emission reduction activities take place currently at micro or small scale by private or non-state initiatives.
