Climate change models are in general developed to assess the future environmental impact of different policy scenarios. Greenhouse gases emission indicators encompass a variety of measurements on the emission and concentration of Greenhouse gases. Greenhouse gases are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of thermal infrared radiation emitted by the Earth‘s surface, the atmosphere itself, and by clouds. This property causes the greenhouse effect. This indicator measures the emissions of the six main GHGs which have a direct impact on climate change. 13 13 14 -This indicator aim to quantify the amount of greenhouse gases (GHG) avoided as a result of implementation of NBS. GHG emissions through NBS can be avoided through reduced consumption of heating and cooling energy demands at building scale for instance. The extend of GHG emissions is one of the most widely used life cycle impact assessment indicators and the amount avoided is usually employed during scenario comparisons. 15 - 16 -CO2-equivalent emission is the amount of CO2 emission that would cause the same time-integrated radiative forcing, over a given time horizon, as an emitted amount of a long-lived GHG or a mixture of GHGs. 14 +This indicator aim to quantify the amount of greenhouse gases (GHG) avoided as a result of implementation of NBS.
