The Copenhagen Accord has proven beneficial to the efforts of achieving the target of limiting global warming to two degrees Celsius. Since the climate conference was held, countries have pledged to reduce their greenhouse gas emissions. These pledges could realise up to 70 per cent of the greenhouse gas reduction that is needed. However, the risk of the actual reductions being less, is substantial. Thus is the conclusion of the report Evaluation of the Copenhagen Accord: Chances and risks for the 2 °C climate goal, by the Netherlands Environmental Assessment Agency (PBL), conducted at the request of the Dutch Ministry of Housing, Spatial Planning and the Environment (VROM) and the European Commission.
