After releasing a report on the issue on Monday, yesterday the EPA finalized rules that require the nation’s largest polluters to report on carbon emissions. The program is similar to the established Toxics Release Inventory (TRI) program, which has been an immensely useful tool for researchers and watchdog groups, and also demonstrated to reduce emissions without further regulation. However, the picture is of course not as simple as that, some feel that the regulations have too many loopholes.

Meanwhile, NewScientist recently noted that if we shared more, we’d need less stuff and that this would dramatically decrease our impact on the environment; economies of scale, et cetera.
