Today, the International Energy Agency put out a report saying that CO2 emissions in 2012 grew by 1.4%, or 31.6 gigatonnes. This increase means that the chances of constraining emissions to cap global warming at 2 degrees C are narrowing.
When I first started covering the cleantech/renewables space for C&EN back in 2008, there was a common belief among technologists and some policy makers that within a few short years, a price would be put on carbon with policies (such as cap and trade or a carbon tax) that would act like jet fuel, powering demand for renewable fuels and related industries.
But as IEA Executive Director Maria van der Hoeven points out, ““Climate change has quite frankly slipped to the back burner of policy priorities.” The good news in the report is that the growth in renewable energy production in the U.S. and Europe has helped those regions decrease carbon emissions. However, it was the switch to shale gas from coal that had the biggest impact on U.S. emissions. In contrast, growing energy demand from China and other developing nations has more than made up for those changes.

IEA is pushing four policies that are all outside of the renewables space. The organization’s plan would shave 8% off the carbon emissions compared to no further constraints by:
1. Making buildings, industry, and transportation more energy efficient, to get 50% of the cut.
2. Limiting construction of the least efficient types of coal-fired power plants, for 20% or more of the cut.
3. Halving methane emissions from upstream oil and gas operations (18% savings)
4. A partial phase-out of fossil fuel consumption subsidies (12%)
