Well this surprised me and in some ways shows up their neighbours to the North (America & Canada)! Mexico set to become only second Country in the World, after the UK, to set long term climate targets into law.

The irony is, of course, that Mexico has traditionally been a younger and poorer cousin of the giant to its north, the United States, which has repeatedly declined to establish legislation of anything like this strength, citing impacts on economic growth. "Power for the US is based on the army and energy and oil," Mr Munoz Ledo said. Oh so true.
