It would be cool if this were true

Carbon dioxide emissions fell by 13% in the past five years, because of new energy-saving technologies and a doubling in the take-up of renewable energy, the report compiled by Bloomberg New Energy Finance (BNEF) for the Business Council for Sustainable Energy (BCSE) said.

Nah. It’s because we’re driving less. Look at the VMT chart. The drop in emissions is mainly due to the bad economy, not renewable energy.



Tar sands mining: peatland destroyed and stored carbon released

They also say that the peatlands under consideration are currently holding on to 11-47 million metric tons of carbon that will be released into the atmosphere as part of the mining process. And then, because the mining companies plan to return the land to dry forest instead of the original peatlands, the area will lose the ability to sequester carbon in the future; this they say will add up to about 5,700-7,200 mt of carbon each year, which they say should be looked at as a net gain of carbon emissions each year.

Abstract:

Oil sands mining and reclamation cause massive loss of peatland and stored carbon.



“Green cars” will not solve the whole greenhouse gas thing

The impossibility of “green cars” must be apparent at this point. EVen to people at websites called “Green Car Congress:” http://www.greencarcongress.com/2012/02/mashayekh-20120212.html

After considering a wide range of possible strategies to reduce light-duty vehicle greenhouse gas emissions, a team from Carnegie Mellon University, RAND Corporation and the University of Toronto has concluded that no one strategy will be sufficient to meet GHG emissions reduction goals to avoid climate change. Strategies considered included fuel and vehicle options; low-carbon and renewable power; travel demand management; and land use changes.

However, they also found that many of these changes have positive combinatorial effects, “so the best strategy is to pursue combinations of transportation GHG reduction strategies to meet reduction goals.” As a result, they recommended that agencies need to broaden their agendas to incorporate such combinations in their planning. Their policy paper is published in the ACS journal Environmental Science & Technology.

So, if we still want to drive around everywhere , we’re left with all these non-effective strategies for reducing emissions. Solution? Implement all these non-effective strategies at the same time!
