Global and Regional Energy Challenges to 2050 and Beyond: Experiences from Assessing Energy Pathways for Europe

چکیده
Climate modeling, such as reported by the Intergovernmental Panel on Climate Change (IPCC), suggests that reductions of 50-85% in global emissions of CO2 (relative to the emission levels in 2000) are required to enable the stabilization of atmospheric levels of greenhouse gases (GHGs) at 440-490 ppm (~350-400 ppm CO2), corresponding to a global temperature increase in equilibrium of 2.0oC to 2.4oC (IPCC, 2007). It is urgent to make these cuts in emissions. The emission levels should peak no later than 2015 with 50% to 70% reductions in GHG emissions required to limit the global temperature increase to 2oC. For this target to be met with >66% probability, further reductions are required after 2050 (Fee et al. 2010).

متن کاملA Comparative Review of Global Transportation Energy Outlook
In 2010, the global transport sector consumed about 2,200 million tons of oil equivalent. About 96% of this amount came from oil. It shows that more than 60% of the oil consumed globally goes to the transportation sector. Road transport accounts for the bulk of the transportation energy consumption. The light-duty vehicles (LDVs), including light trucks, light commercial vehicles, and minibuses...
