High-quality carbon accounting is crucial to achieving net-zero emissions targets. In recent years, the proliferation of carbon accounting frameworks has created opportunities and challenges for companies, regulators, and stakeholders. This report systematically introduces the experiences of these carbon accounting frameworks in the EU and Germany, offering insights into their characteristics, applications and opportunities for improvement. It aims to inform policy makers, real economy actors and accounting consultants alike to learn from the existing ecosystem of carbon accounting in the real economy in Germany and the EU, and thus provide a reference for the further development of China’s carbon accounting framework. This report is an output of the Sino-German Cooperation on Climate Change – NDC Implementation Project.
