This week's edition of Environment weekly highlights includes: news analysis on publication by the Competition and Markets Authority (CMA) of guidance on environmental claims for fashion brands, the implications of a recently published report highlighting the extent of the PFAS contamination problem in England, the decision in Weston Homes v SSHULC, where the High Court granted an application for statutory review of an inspector’s decision refusing Weston Homes plc’s planning application on grounds related to consideration of biodoversity net gain (BNG), consistency in decision-making, failure to take into account an obviously material consideration and a failure to provide legally adequate reasons, and claims from a US paper lobby that EU Deforestation Regulation compliance is ‘not possible’. In addition, this week the Department of Agriculture, Environment and Rural Affairs (DAERA) has published Northern Ireland’s first Environmental Improvement Plan (EIP), a pilot version of the UK Net Zero Carbon Buildings Standard has been launched and the Department Environment, Food and Rural Affairs (Defra) has published the updated illustrative base fees for the first year of the extended producer responsibility (EPR) for packaging, and has announced new legislation, aimed at supporting precision breeding technology to boost food security.
