The scientific community is now developing a new set of scenarios, referred to as Shared Socio-economic Pathways (SSPs) to replace the SRES scenarios. To be used to investigate adaptation and mitigation, SSPs need to be contrasted along two axes: challenges to mitigation, and challenges to...

In the absence of incontrovertible scientific evidence to forecast the consequences of global warming - or the costs of preventing it - the debate over emissions targets has often been driven by personal and political interests. Mark Bernstein, Scott Hassell, and Robert Lempert argue that...

The purpose of the study is to model scenarios of technological innovations in the global passenger vehicle fleet, i.e., improvements in the energy economy of average regional vehicle fleets and blending of alternative fuels. This is to quantify the potential CO2 emission reductions that may...
