COP28 deal backs global hydrogen scale-up

Agreement calls for acceleration of hydrogen production and other low-carbon technologies as global emissions trajectory falters

Nearly 200 governments have pledged to join a global effort to accelerate the scale-up of low-carbon hydrogen production as part of a green technology push aimed at achieving net zero by 2050, according to the final deal struck at the COP28 climate summit in Dubai.
