Saudi Arabia sets target of net zero greenhouse gas emissions by 2060

One of world's biggest oil exporters more than doubles its annual target to reduce carbon emissions

One of the world's largest oil producers, Saudi Arabia, has announced it aims to reach net zero greenhouse gas emissions by 2060 to curb manmade climate change.

Alongside the pledge made on Saturday the Saudis made no mention of reducing investment in oil and gas or moving away from the production of fossil fuels. Riyadh is forecast to make $150bn (109bn) in oil revenues this year alone.
