Via Wonkbook, a World Bank description of all the carbon pricing schemes in place or that have passed some level of approval at national or subnational levels. More than you'd think, and somewhat cheering when you remember that pricing is only one part of efforts to restrict emissions for many of the listed programs.
I need to really sit down with the part on the regional-level projects in China, but the first thing I wanted to check was Mexico. I had been excited to see a climate change law passed in the country, but according World Bank, not much has happened yet on the national level for a pricing scheme (see page 74). Other things are happening at regional levels in cooperation with California's program.
Hopefully the World Bank's descriptions will become incomplete soon.
