The United Kingdom has adopted ambitious emissions reduction targets, making it the first major economy in the world aiming to end its contribution to global warming by 2050.
The country is preparing to phase out its last coal-fired power plants by 2025 to reduce carbon emissions.
The UK's National Grid, which supplies electricity to England, Scotland and Wales, says coal is "quickly becoming an irrelevance" in Britain.
While the UK's net zero target has been hailed as historic, critics say 2050 is too far away and more needs to be done now to protect the environment.
