A Qunatitative Assessment of their Emission Reduction Impact

image of Climate Commitments of Subnational Actors and Business

This report present a quantitative assessment of the total greenhouse gas (GHG) emissions mitigation impact in 2020 of current non-state climate action. Its focus is initiatives with the potential to be large scale. The report predicts that over the next few years, new targets for the post 2020 period will be agreed by existing and new members of initiatives. Thus any quantification now for post 2020 would likely lead to an underestimate of the contribution from initiatives. The total calculated impact represents the GHG emission reduction and takes into account overlaps between initiatives. It also estimates to what extent the emission reductions are additional to those achieved through climate action of national governments.



Company initiatives

The corporate sector plays a crucial role in the combat against climate change. The top 1,000 largest greenhouse gas (GHG) emitting companies are responsible for the annual emission of 10 GtCO2e, or about 20% of the world’s annual GHG emissions. Various initiatives exist trying to catalyse emission reductions in this sector, with almost a quarter of the top 1,000 emitting companies participating in one or more initiatives (Wouters, 2013).
