Lots of greenhouse gas and carbon trading news last Friday.

The Bush Administration’s major air pollution initiative, regulating the emission of sulfur dioxide, nitrogen oxide and other major pollutants, was struck down by a federal appeals court. The ruling came as a bit of a surprise, as many utilities had been planning on entering the cap-and-trade market that the initiative would have created.

Ironically, a spokeswoman for North Carolina Attorney General Roy Cooper, who filed the suit, stated that Cooper did not agree with the ruling. When he first filed the suit, Cooper said that loopholes in the rule would actually allow emissions from neighboring states’ power plants to pollute North Carolina’s air.

In addition, on the same day the head of the EPA said the Clean Air Act was the wrong tool for regulating greenhouse gas emissions, and that Congress needed to be responsible for passing such regulations.

Also on Friday the ten Northeast and Mid-Atlantic States participating in the Regional Greenhouse Gas Initiative (RGGI) issued a preliminary release of technical materials for market participants interested in bidding in their first-in-the nation auction of carbon dioxide (CO2) allowances this September.

And earlier in the week the EU reached a provisional agreement to include airlines in their Emission Trading Scheme (ETS), beginning in 2012. Currently only 3 percent of all carbon dioxide emissions in the EU are generated by aviation. However, without new carbon emission regulations this percentage should increase over the next decade, as power producers lower their carbon emissions and air travel in the region increases.

The Globe and Mail looks at how Wall Street is gearing up for a US carbon market that could potentially rival the European market. Banks are choosing to invest in energy projects based on its potential to lower greenhouse gas emissions, as seen with Credit Suisse’s recent deal with state-owned China Huadian Group to provide financing for wind farms in Inner Mongolia in exchange for CERs. The credits make the project more attractive as an investment, as selling of the credits increases the investment’s return.

Japan’s largest utility, Tokyo Electric Power Co (TEPCO), announced that it is building its first wind farm, according to Reuters. The 11 wind turbines, total capacity of 18.37 megawatts, are scheduled to start commercial operations in October 2011, and are projected to reduce carbon emissions by 12,000 tonnes per year.

Financial News discusses the increase in the European Union carbon emissions trading from $24.4 billion in 2006 to $50 billion in 2007. Increased investing and a better market infrastructure have continually helped the market to grow, along with a rise in permit prices after the European Commission, which issues carbon dioxide quotas, allocated fewer permits.
