The study finds that by 2020, the greenhouse gas
emissions intensity of electricity generation in
certain areas will have improved by as much as 30 percent over 2010 levels.
Instead of this top - down approach, Ritchie and colleague Hadi Dowlatabadi, also from the University of British Columbia, generated climate outlooks the other way around, mapping out all the combinations of carbon
intensity and energy use that could generate a
certain level of carbon
emissions as given by the RCPs.
