Karl Tomusk The UK Green Building Council has published “vital” guidance on ensuring that net-zero buildings and organisations in the UK are truly sustainable, setting out principles around high-quality renewable energy procurement and carbon offsets. The guidance seeks to ensure that organisations and buildings make credible net-zero claims and avoid “greenwashing” – giving the impression of being environmentally conscious without making a meaningful difference. Renewable energy is among the key themes in the report, which argues that the procurement of green energy in the UK has a limited impact and, in some cases, no impact at all on emissions reductions for the organisation or for the country.
