BP Energy Outlook 2030 sees emerging economies leading energy growth to 2030; global CO2 emissions from energy well above IEA 450 scenario

Green Car Congress

In both the base-case and a scenario with more aggressive environmental policies, CO 2 emissions from energy use remain well above the IEA 450 scenario. Non-OECD countries are seen to rapidly increase their share of overall energy demand from just over half currently to two-thirds. Click to enlarge.
