US: The Oregon Department of Environmental Quality is receiving public comment on its revised 2021 Climate Protection Program, under which natural gas users, including gypsum wallboard producers, will face tighter emissions regulations. The programme will enable plants to buy credits for emissions above regulation level, with the money raised primarily going to fund community-based projects. Local press has reported that the revised rules aim to help realise a 50% reduction in CO2 emissions by 2035 and a 90% reduction by 2050. The latest revision also shortens companies’ compliance period from three years to two.
