William Chandler’s recommendations on how we can cooperate to lower emissions

William Chandler, director of the Carnegie Energy and Climate Program, has borrowed my phrase for the title of his new study: "Breaking the Suicide Pact: U.S.-China Cooperation on Climate Change." It begins:

Together, China and the United States produce 40 percent of global greenhouse gas emissions. Their actions to curb or expand energy consumption will determine whether efforts to stop global climate change succeed or fail. If these two nations act to curb emissions, the rest of the world can more easily coalesce on a global plan. If either fails to act, the mitigation strategies adopted by the rest of the world will fall far short of averting disaster for large parts of the earth.

These two nations are now joined in what energy analyst Joe Romm has aptly called "a mutual suicide pact." American leaders point to emissions growth in China and demand that Chinese leaders take responsibility for climate change. Chinese leaders counter that American per capita greenhouse gas emissions are five times theirs and say, "You created this problem, you do something about it."

New report on massive growth of renewables last year

Climate Progress is the title of my blog posts' main home, as much as the "progress" part strains credulity at times. I only see two major quantitative areas of sustained progress: clean energy deployment (especially in Europe) and private sector clean-tech funding.

Those folk at Clean Edge, who wrote the best 2007 book on clean tech, The Clean Tech Revolution, have quantified these gains -- and made predictions about the future -- in a new report you can read here. Some interesting factoids:

Please don’t use incandescent bulbs for heating

Please.

As Andrew Leonard writes in his "How the World Works" blog, this all began with a column by ...

Toronto Star energy reporter Tyler Hamilton that itself had summarized the conclusions of a study raising questions about whether it always makes sense to replace incandescent light bulbs with CFLs. The nub of the argument was that in some cases the heat generated by the incandescent light bulbs could be useful.

Tyler is a friend of mine and a great reporter, so I sent him an email explaining why this is not true, which was not written for publication. Then Leonard himself summarized the column on his blog. So, as Leonard explains:

A factor of 3.67 makes a big difference when discussing climate

The biggest source of confusion and errors in climate discussions probably concerns "carbon" versus "carbon dioxide." I was reminded of this last week when I saw an analysis done for a major environmental group that confused the two and hence was wrong by a large factor (3.67). The paragraph I usually include in my writing:

Some people use carbon rather than carbon dioxide as a metric. The fraction of carbon in carbon dioxide is the ratio of their weights. The atomic weight of carbon is 12 atomic mass units, while the weight of carbon dioxide is 44, because it includes two oxygen atoms that each weigh 16. So, to switch from one to the other, use the formula: One ton of carbon equals 44/12 = 11/3 = 3.67 tons of carbon dioxide. Thus 11 tons of carbon dioxide equals 3 tons of carbon, and a price of $30 per ton of carbon dioxide equals a price of $110 per ton of carbon.
