Mexico, the world's 11th largest CO2 emitter, legally committed to emissions reductions yesterday:
The limits are rather severe: a mandate to reduce CO2 emissions by 30% below business-as-usual levels by 2020, and by 50% below 2000 levels by 2050.
It also requires "that 35% of the country's energy should come from renewable sources by 2024, and requires mandatory emissions reporting by the country's largest polluters."
The bill passed Mexico's lower house by 128-10, and passed unanimously in their Senate.
According to the 2011 IEA report CO2 Emissions from Fuel Consumption, here are the comparisons for 2009:
per capita emissions (t CO2/yr):
emissions per GDP (PPP basis) (t CO2/$1000):
Total emissions as percent of world total (2009: 28,999.4 Mt CO2):
Energy supplied per capita:
World: 2.4 kW
USA: 9.3 kW
Mexico: 2.2 kW
Note: this only counts emissions from fuel consumption, not land use changes. And only CO2, not the other GHGs.
So Mexico is making a pretty big commitment, given their already-low per capita emissions.... In essence, the skinny people are dieting to reduce the world's obesity.
