Despite emissions falling in 2020 at the fastest rate for nearly a century, scientists are worried they will rebound in 2021 as lockdown restrictions ease and'normal life' resumes. Across the business community, growing concern about climate change is driving greater action: with the majority of UK business leaders planning to increase long-term investment in sustainability initiatives. This is a shift in the right direction, but the tricky next step is making sure such green efforts actually drive change. While over half of company leaders recognize this calls for better green measurement, achieving that is difficult with limited frameworks for green reporting available both globally and locally. Additionally, business leaders are now responsible for the sustainability efforts of their entire network of suppliers, which means clear oversight is key in holding partners accountable for'greenwashing' – where organizations claim to be green through use of renewable energy, but they do not have the necessary processes in place to offset their overall carbon footprint.
