British Prime Minister Theresa May has committed the UK to reach net zero carbon emissions by 2050, becoming the first major economy to do so.

Mrs May says reaching net zero emissions by 2050 is an ambitious target, but it is crucial to ensure the planet is protected for future generations.

Chief scientist for Greenpeace UK, Doug Parr, welcomed the target but says loopholes allowing the use of international carbon credits will shift the burden to developing nations.
