Chapter 7, Development of Sustainable Goals Emissions Reduction Value to Measure Climate Change

The Sustainable Development Goals, or SDGs, goal indicators and the steps taken to slow down climate change have trade-offs and synergies. Although some research has evaluated these linkages, nothing is known about how much of an interaction there is. This section illustrates how reducing CO2 emissions relates to the SDGs. They created the “marginal SDG-emissions-reduction values (MSVs),” which show how a unit decrease in CO2 emissions affects certain SDG indicators on a marginal basis. This measure was utilised and may be used for national evaluations. They discovered significant correlations between rates of CO2 emission reduction and several SDG objectives. For example, a 1% reduction in CO2 may save 0.57% of premature deaths linked to air pollution (SDG3), whereas the same CO2 reduction can result in a 0.026% drop in mean species richness (SDG15) (excluding the effects of climate change). Our results help evaluate the implications of CO2 emissions reduction objectives for the SDGs, which will assist in informing national climate strategies.
