IEA: Global CO2 emissions up by 1.0 Gt (3.2%) in 2011 to record high

Green Car Congress

However, China’s carbon intensity—the amount of CO 2 emitted per unit of GDP—fell by 15% between 2005 and 2011. China made the largest contribution to the global increase, with its emissions rising by 720 million tonnes (Mt), or 9.3%, primarily due to higher coal consumption. Gt, the IEA said.

Study Finds That CO2 Standards for Vehicles Can Reduce Price of Oil

Green Car Congress

A new study by the French institute Enerdata, commissioned by the European Federation for Transport & Environment (T&E), suggests that the European CO 2 standards for new vehicles due to come into effect in 2012 will lead not only to a European savings on oil (mainly via lower oil import volumes) but also to slightly lower global oil prices.

Annual Increase in Global CO2 Emissions Halved in 2008; Decrease in Fossil Oil Consumption, Increase in Renewables Share

Green Car Congress

In addition to high oil prices and the financial crisis, the increased use of new renewable energy sources, such as biofuels for road transport and wind energy for electricity generation, had a noticeable and mitigating impact on CO 2 emissions. Global CO2 emissions increased from 15.3 Source: PBL. Click to enlarge.

Study finds that dry-feed gasification for coal-to-liquids is more efficient, lower-emitting and cheaper than slurry-feed; CCS cost-effective for reduction of CO2

Green Car Congress

Even with CCS, the liquid product costs are comparable to recent crude oil prices. For a liquids-only configuration, CCS is a cheaper option when the CO 2 price exceeds $12/tonne. Plant-level CO 2 emissions can be greatly reduced by using the CCS technology, the study found, without much increase in capital cost.

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

At the same time, oil—and gas—import dependency in the US is likely to fall to levels not seen since the 1990s, because of improved fuel efficiency and the increased share of biofuels. Global consumption growth is also impacted by higher oil prices in recent years and a gradual reduction of subsidies in oil-importing countries.
