New Law Buoys U.S. Efforts to Make Ocean-Going Ships Cleaner

U.S. agencies have taken another step forward in implementing a key international agreement to reduce air pollution from large ships. Yesterday, President Bush signed into law the Maritime Pollution Protection Act of 2008, which clears the way for U.S. ratification of the international treaty regulating emissions – known as MARPOL Annex VI - from large diesel-powered, ocean-going vessels.

Under MARPOL Annex VI, container ships, tankers, cruise ships and bulk carriers must limit NOx emissions from their category three diesel engines. It also sets a cap on the sulfur content of the fuel they burn and includes a program for designating areas where more stringent fuel controls apply, such as near coastlines that have more severe air quality concerns.

According to the EPA, MARPOL stakeholders will work to strengthen NOx and SO2 standards and the sulfur requirements in fuel this October. If adopted, these stronger international standards have the potential to yield significant environmental and public health benefits in the U.S. and around the world (Read more about reigning-in the pollution caused by oceangoing vessels at the EPA’s website.)

Canadian Groups Battle Large-Scale Hydropower Bound for U.S. Electricity Markets

As part of electricity restructuring efforts in the last few years, 25 states have adopted a Renewables Portfolio Standard (RPS). This new policy promotes renewable energy sources that are consistent and compatible with competitive electricity markets and if efficiently implemented can develop 3,800 MW of new renewable energy capacity…North of the border in La Belle Province, Quebec, the public utility Hydro-Quebec is eager to capitalize on rising energy prices and high demand from the Northeastern and New York sates.

That Old Wilderness Magic Is Still Alive

Just as the authors of the Wilderness Act intended, protecting the Wild Sky Wilderness was a great American cause beyond the dividing lines that crisscross American society.

Not that it was easy to accomplish. For wilderness, it never is. From the day that local activists first drew the Wild Sky’s lines on maps until the day that President Bush signed his name to the authorizing legislation, nine years elapsed.
