John McDonnell, the shadow chancellor, pledged his government would ensure firms are “pulling their weight” to tackle the “existential threat” to the planet.
And he warned: “For those companies not taking adequate steps under Labour they will be delisted from the London Stock Exchange.”
Vowing to “rewrite the rules” of the economy to benefit workers, Mr McDonnell also insisted curbing the climate crisis would be “Labour’s overriding priority” if it wins the general election.
The Corporate Governance Code would be beefed up to “set out a minimum standard for listing related to evidencing the action being taken to tackle climate change”.
“If we are meet the climate change target to keep global warming to 1.5 degrees above pre-industrial levels, we need to ensure that companies are pulling their weight alongside government,” he told an event in London.
And, claiming some support from the corporate world, he added: “Business bodies are calling for companies to improve climate related financial reporting and for all companies to bring forward decarbonisation plans.”
Earlier, the Green Party lashed out at Labour for dropping plans to achieve net zero carbon emissions by 2030, as a shadow cabinet minister revealed on Monday.
It said the decision proved only the Greens are willing to wage “a war” on climate change, with a £100bn pledge to end emissions by that date.
