LONDON: Half of the world’s 2,000 biggest listed companies have set a target to get to net-zero emissions by mid-century, but just a fraction meet tough United Nations guidelines for what constitutes a quality pledge, a report on Monday showed.

Net Zero Tracker, an independent data consortium including Oxford University, said corporate targets from Forbes 2000 index companies had jumped 40% to 1,003 in October 2023, from 702 in June 2022, covering two-thirds of revenues, some $27 trillion.

However, just 4% of the targets meet the criteria laid down by the UN’s Race to Zero campaign, for example by covering all emissions, starting to cut them immediately, and including an annual progress update on interim and longer term targets.

Of those to set a target, just 37% had one that covered their Scope 3 emissions, or those tied to a company’s value chain. Just 13% had a quality threshold for the use of carbon offsets.

The pace of change among governments and corporates is set to form a central part of the COP28 climate talks in Dubai starting in late November.
