"Fossil-fuel carbon dioxide emissions from Mexico grew exponentially at a rate of 6.5% per year from 1891 to 1982. Since 1982, total fossil-fuel CO2emissions have slowly grown and now stand at 130 million metric tons of carbon. Emissions growth over time has been due to increasing oil production and in 2008, 59.8% of emissions were from petroleum products, the highest fraction of crude oil dependence of the major CO2-emitting countries."
