BBC discusses a study that pours cold water on oil company net zero claims.
Claims by oil and gas companies that they are curbing their carbon emissions in line with net zero targets are overstated, according to a new review.
The independent analysis of six large European corporations acknowledges they have taken big steps on CO2 recently.
In April, Shell became the latest to announce ambitious plans to be at net zero for operational emissions by 2050.
But the authors say none of the companies are yet aligned with the 1.5C temperature goal.
Scientists argue that the global temperature must not rise by more than 1.5C by the end of the century if the world is to avoid the worst impacts of climate change.
The research has been carried out by the Transition Pathway Initiative (TPI), an investor-led group which investigates how companies are preparing for the move to a low-carbon economy.
