CDP (formerly the Carbon Disclosure Project) has been gathering environmental data from asset owners, companies, regions and municipalities for over two decades. In 2021 the non-profit organisation sought to include a range of forward-looking elements within its questionnaire with a view to evaluating the quality and viability of the CDP membership’s climate transition plans. The latest report shows overall results that are marginally worse than last year’s, but this is largely down to a strengthening of the science-based criteria used to define a credible transition plan.
