Ethanol industry questions EPA lifecycle GHG emissions analysis
Posted on 6 Nov 2008 by Thomas H. Clarke, Jr.

Using the classic Executive Branch backdoor/end-run around an agency [a common practice in all of the last Administrations stretching back to the 1970s], the ethanol industry has met with OMB to raise questions about EPA's proposed lifecycle emissions... Read More

California may get the award for energy efficiency, but it is the second largest emitter of CO2; Texas is first
Posted on 4 Nov 2008 by Thomas H. Clarke, Jr.

DOE's Energy Information Administration has released its statistics for energy-related CO2 emissions for the time period 1990 to 2005. The information is broken down by State. The data focuses just on CO2, not on all GHGs. However, as EIA notes: "Although... Read More

President directs EPA to review California waiver request to allow regulation of GHG emissions from cars
Posted on 28 Jan 2009 by Thomas H. Clarke, Jr.

As noted in a prior post, California has reapplied to EPA for a waiver from the Clean Air Act (CAA) which will enable California and 17 other States to regulate GHG emissions from automobiles under the CAA. President Obama has now ordered EPA to revisit... Read More

Solar Car Drives Home Message To Climate Conference Delegates
Posted on 4 Dec 2008 by Gregg Lawson

Maybe a globe-trotting solar car will drive home the message that we have the tools to fight global warming. The two-seater, the first of its kind to travel around the world without using a single drop of gasoline, arrived today at the U.N. climate... Read More

RGGI's second auction prices CO2 allowances at $3.38 per ton, up from $3.07
Posted on 14 Jan 2009 by Thomas H. Clarke, Jr.

Prior posts have described the Regional Greenhouse Gas Initiative and the pricing of carbon dioxide allowances sold at its first auction. The RGGI has now held its second auction of CO2 allowances; each allowance permitted its holder to emit one ton of... Read More

Posted on 20 Dec 2008 by Thomas H. Clarke, Jr.

There are a lot of quack fuel additives and mileage enhancers sold in today's market. See, for example, . Thus, it was with some interest that I read about a device that appears to have... Read More

Coal-to-liquid and oil-sand-extraction may become economically viable in the future, but they are unlikely to help the environment, says RAND Corp.
Posted on 8 Nov 2008 by Thomas H. Clarke, Jr.

Both high import payments for petroleum motor fuels and concerns regarding emissions of carbon dioxide (CO2) are motivating interest in possible fuel substitutes. Petroleum products derived from conventional crude oil constitute more than 50 percent of... Read More

Voluntary FAA program to reduce emissions at airports is very modestly successful
Posted on 24 Nov 2008 by Thomas H. Clarke, Jr.

In 2004, the Federal Aviation Administration established the Voluntary Airport Low Emissions (VALE) program. VALE allows airports to use federal money normally set aside for noise and air quality projects to be used for emissions reduction programs. Currently... Read More

Using rock formations, really, to reduce greenhouse gases
Posted on 19 Nov 2008 by Thomas H. Clarke, Jr.

In a prior post I noted that the IEA was pitching the construction of 10,000 carbon capture and storage projects in order to keep GHG emissions to a level that may limit the increase in global temperature to 3 degrees C or less over the next century.... Read More

Tailpipe Emissions Are Too Narrow A Focus For Assessing GHG Impacts From Various Transportation Modalities
Posted on 24 Jun 2009 by Thomas H. Clarke, Jr.

In a recent study, researchers argue that many analyses of the impact of GHG (greenhouse gas) emissions overlook those GHG's emitted in constructing and maintaining the transportation infrastructure. For example, based on passenger kilometers traveled... Read More

Air Resources Board considers alternative to GHG emission limits for vehicles
Posted on 22 Nov 2008 by Thomas H. Clarke, Jr.

Although the conventional wisdom is that the Obama Administration, unlike the Bush Administration, will approve California's request to be able to regulate GHG emissions from vehicles under the Clean Air Act (CAA), the California Air Resources Board... Read More

Midwest creates GHG monitoring and trading scheme, though some details are still being developed
Posted on 10 Nov 2008 by Thomas H. Clarke, Jr.

As noted in prior posts, California, some western States, and several Canadian provinces have created a GHG trading program; similarly, a number of northeastern States have created a GHG trading program, and begun the bidding process for allowances. Now... Read More

International Energy Agency claims that 10,000 large-scale carbon sequestration projects needed by 2050 to avoid major global warming
Posted on 19 Nov 2008 by Thomas H. Clarke, Jr.

According to the International Energy Agency, there are only four carbon capture and storage ("CCS") projects in operation today, and none involves capturing emissions from coal-fired power plants. There are two off-shore projects in Norway... Read More

Taxing carbon will have only a modest impact on emissions from the transportation sector, concludes CBO
Posted on 27 Oct 2008 by Thomas H. Clarke, Jr.

Although putting a price on carbon would increase fuel prices and curb vehicle use, the Congressional Budget Office concludes that price changes will be too small to have much of an impact. Contrary to the prattle from the media, CBO notes that the doubling... Read More

Substantial quantities of extractable methane hydrates identified in Alaska
Posted on 14 Nov 2008 by Thomas H. Clarke, Jr.

Methane hydrates (aka frozen gas, frozen methane, gas clathrates, gas hydrates, clathrate hydrates) are water ice that contain a large amount of methane (aka natural gas) within their crystalline structure [see Read More
