To reach net-zero by 2050, the International Energy Agency (IEA) has announced that no new fossil fuel boilers should be sold from 2025.

This comes as one of the 400 steps to delivering net-zero proposed by the IEA in their report, alongside stopping the sale of new petrol and diesel cards around the world by 2035.
Other methods of home-heating will be implemented, such as the switch to burn hydrogen, despite hydrogen being in limited supply. The obvious substitute for the gas boiler will be heat pumps, which extract warmth from the air, ground or water.
To meet this step, the number of wind and solar energy installations would need to increase four-fold, creating 14 million jobs worldwide by 2030, according to the IEA.
Faith Birol, the IEA's Executive Director, said:
"The scale and speed of the efforts demanded by this critical and formidable goal - our best chance of tackling climate change and limiting global warming to 1.5C - make this perhaps the greatest challenge humankind has ever faced."
"The IEA's pathway to this brighter future brings a historic surge in clean energy investment that creates millions of new jobs and lifts global economic growth. Moving the world on to that pathway requires strong and credible policy actions from governments, underpinned by much greater international co-operation."
