Mexico could follow the UK’s example and become the second country in the world to introduce national climate change laws.

The environmental charity WWF is urging Mexico’s Congress to adopt the first version of the Mexican Climate Change Law at a vote expected to take place tomorrow.

Some companies in the country’s steel and coal sectors are opposing the law but WWF is appealing to Mexican politicians to back the proposed legislation.

The charity said in a statement: “On 29th March the final word is in the hands of the members of Congress from all political parties who need to demonstrate Mexicans and the world their conviction and determination through the approval of an ambitious Law.”
