IIASA: removing fossil fuel subsidies will not reduce CO2 emissions as much as hoped

Green Car Congress

Removing fossil fuel subsidies would have only a small effect on CO 2 emissions and renewable energy use, according to a new study led by the International Institute for Applied Systems Analysis (IIASA) and published in the journal Nature. First, these subsidies generally apply only to oil, gas, and electricity. This equates to 0.5-2

CFR Report Says Energy Security and Climate Change Concerns With Oil Sands Can be Reconciled

Green Car Congress

A new report from the Council on Foreign Relations (CFR)— The Canadian Oil Sands: Energy Security vs Climate Change — claims that prudent greenhouse gas regulations can limit emissions from Canadian oil sands while still enabling robust development of the energy resource. Levi, CFR’s David M.

Global CO2 emissions up 3% in 2011; per capita CO2 emissions in China reach EU levels

Green Car Congress

CO 2 per capita emissions from fossil fuel use and cement production from the top 5 emitting regions. Global emissions of CO 2 increased by 3% last year, according to the annual report “Trends in global CO 2 emissions”, released by the EC Joint Research Centre (JRC) and the Netherlands Environmental Assessment Agency (PBL).

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. However, both cases result in global CO 2 emissions well above the IEA 450 scenario—a back-cast which illustrates what is required to stabilize greenhouse gas concentrations at 450 ppm.

Examples of emerging oil sands related technologies and trade-offs. The paper is an examination of how various choices about the scale of the life cycle analysis applied to oil sands (i.e., However, this only accounts for the processing that occurs in Canada and therefore excludes much of the refining and transport emissions.
