Global emissions hit record highs in 2022.
A report from the International Energy Agency shows the total was still lower than originally expected.
The increase has been put down to increased air travel, while emissions from coal grew with many countries forced to use more of it due to the ongoing Russian invasion of Ukraine.
Most years since 1900 have seen an increase of emissions - one exception being 2020 when travel fell due to the pandemic.
There are global targets to limit warming to 1.5 degrees, and one main way to do that is limit the earth's carbon emissions.
2022's emissions were lower than expected due to an increase in renewable energy use.
Environment journalist and Last Word contributor John Gibbons says says despite the lower than expected numbers, it's still not good:
"Making progress slowly is the same as failure.
"We have hard targets we have to avoid if we continue on.
"This trajectory takes us straight past 1.5, two degrees, 2.5, even three degrees centigrade.
"So this is a trajectory for global climate disaster."
