…battalions of companies, cities and regions promising to deliver deep emissions reductions are expanding fast…a new report released today by the Yale University's Data Driven Environmental Solutions initiative…attempts to add up the emission reduction commitments submitted to the UN by businesses, cities and regional governments...It calculates that promised emission reductions from over 10,000 non-national government organisations are now equivalent to the global emissions of the iron and steel sectors…However, it added that "the total mitigation potential of all of NAZCA's private sector actions…could be 10 times greater than that, since the Global 500 companies make up approximately one tenth of NAZCA's private sector commitments". The report underlined how businesses and regional governments could deliver globally significant emissions reductions, alongside the promised national emissions reductions contained in the INDC action plans that have been submitted by governments…The new report followed the launch yesterday of an online comparison tool by the ECIU think tank that provides a portal for businesses and policy makers to assess countries' progress and pledges on climate change.
