Developments in Accra
The Accra UN meeting kicked off with more discussion of sectoral targets. Under this kind of system, countries would commit to reducing emissions from particular part of the economy (cement production, for example), instead of committing to a country-wide cap on emissions.
This may help relieve an impasse between developed and developing countries, but it is unclear (and somewhat unlikely) whether sectoral targets alone will reduce emissions in time to get to 350.
For more of an inside scoop, our friends at Taking it Global are blogging the conference also.
