Thank you for the question.
There's a lot of interest in offsets, as I mentioned earlier, as a cost containment mechanism. I'm looking at some in front of me, and many of them, such as the Bingaman bill, the bill from Senators Feinstein and Carper--which is more focused on the utilities sector--the McCain and Lieberman bill I mentioned before, and others allow for the use of emissions offsets as a cost-savings mechanism. Some have criteria already set up in certain categories in which people feel the emissions are more credibly verifiable. There is biological sequestration; industrial offsets that aren't covered, for example, in the first program, so you can go to non-coverage sectors; certain forced-management practices; and even international credits through a mechanism like the CDM itself or through a comparable mechanism that would allow people to verify what's coming in. Many people are considering them because they are a tool for cost containment. Certainly businesses of the kind we work with on the Business Environmental Leadership Council like to see the use of emissions offsets.
