A report from the International Energy Agency has laid out a roadmap for countries to achieve net-zero carbon dioxide emissions by 2050, but it warns that governments must act fast to slow climate change.
Called Net Zero by 2050: a Roadmap for the Global Energy Sector, the report states that current climate pledges made by governments "fall well short" of what is required to achieve net-zero carbon dioxide emissions by 2050.
To reach net-zero, countries must add no more carbon dioxide to the atmosphere than they take out.
Suggestions from the report, which sets out over 400 milestones that need to be achieved to meet the target, include banning the sale of new fossil-fuel run vehicles, rapidly scaling up renewable energy projects and immediately stopping investment in new fossil fuel supplies. Net-zero by 2050 "still achievable"
The International Energy Agency (IEA) is an intergovernmental organisation based in Paris that advises its members, who are all signatories of the Paris Agreement, on how to manage their energy supplies.
The energy sector is responsible for around three-quarters of global greenhouse emissions, according to the IEA.

"Our Roadmap shows the priority actions that are needed today to ensure the opportunity of net-zero emissions by 2050 ? narrow but still achievable ? is not lost," said IEA executive director Fatih Birol.
"The scale and speed of the efforts demanded by this critical and formidable goal ? our best chance...
