Mexico : Currently Mexico is working on a low carbon development model to reduce their CO2 emissions. Mexico has designed the Special Climate Change Program, which is the countries agenda to deal with climate change and adaptation. Companies in Mexico are willingly inventorying their greenhouse gas emissions. At COP13 Mexico ranked fourth on the Climate Change Performance Index (whereas the US ranked 55 out of 56.) Mexico is currently increasing renewable energy sources, energy efficiency, as well as planting forests. This “will reduce the country's greenhouse-gas emissions by 110 million tons by the year 2020.” Mexico is very interested in solving the climate change issue and is working very hard to reach very reasonable goals; they are more than just talk, but a lot of action too. Mexico is helping to lead the Americas and Least Developed Countries.
