...underwhelming arguments. First, advocates point out that the technology reduces emissions of certain air pollutants such as mercury, nitrogen oxides, and sulfur dioxide. Yet this apparent concern for environmental consequences obscures a lesser-known fact: Unless coal is replaced by significant amounts of biomass, gasification plants emit as much CO2 as traditional plants. To combat high emissions, Massachusetts’s Senate bill requires that gasification emissions match those of natural gas. What looks like a step in the right direction remains problematic: Ultimately, incentivizing the burning of any fossil fuel, coal or natural gas, is not environmentally sound...
...decline primarily because of decreasing rates of Amazon rain-forest deforestation, which is the main source of carbon emissions in Brazil, and increasing use of ethanol fuel. Furthermore, from 1970 to 2005 the use of ethanol in our energy mix has averted the emission of 644 million tons of CO2, the equivalent of Canada's annual emissions. When compared with the unsustainable energy patterns used in major developed countries, the Brazilian experience can be considered a model. Contrary to what the article claims, ethanol has been a central part of the solution. Antonio de Aguiar Patriota, Ambassador of Brazil...
...This means that the 50,000 gallons of 20 percent biodiesel used by campus vehicles yearly cut total emissions of CO2 78,000 pounds—the equivalent of taking about eight average American cars off the road. That isn’t bad for one relatively small college. Moreover, soy-derived biodiesel is a byproduct of soybean processing, and its production does not decrease the food supply as greatly as that of corn or sugarcane ethanol...
...coal industry would prefer not to go out of business, and it is trying to delay big emissions cuts for a decade or two, until it perfects the technology to capture and store the CO2 its power plants emit. Lieberman and Warner won't delay those cuts (Clinton, Obama and McCain don't want to either), but they want coal to survive, so their bill gives the industry $235 billion for R&D over the next 20 years. Even so, politicians who represent what's left of America's coal-fired industrial heartland aren't rushing to support the bill...
...first U.S. publisher to measure the carbon footprint of our entire supply-and-disposal chain, from logging operations to landfill. We have increased the percentage of our paper that comes from sustainably managed forests, from 25% to 69%. We have asked our paper companies to reduce CO2 emissions at least 20% by the year 2012. And we're co-sponsoring a campaign called Remix to promote the recycling of our magazines. These efforts have been led by Time Inc. CEO Ann Moore and engineered by David Refkin, our director of sustainable development. We are also pleased to work with...
