This report summarizes the results of an international trend survey on scientific evidence for climate change mitigation conducted by the Ministry of Economy, Trade and Industry in FY 2024.
For policy formulation of climate change measures, objective evidence based on the latest scientific knowledge is essential. It is important to continuously understand and analyze reports from international organizations including the IPCC (Intergovernmental Panel on Climate Change) and the latest research results from research institutions in various countries.
This survey conducted detailed analysis of the latest scientific knowledge on climate change mitigation, international research trends, and the utilization status of scientific evidence in policies of various countries. The basis for setting greenhouse gas reduction targets, evaluation methods for mitigation technologies, and measurement and verification methods for policy effects were examined.
Survey results confirmed that while advances in climate science have enabled more precise impact prediction and countermeasure evaluation, the importance of appropriate handling of uncertainties and analysis considering regional characteristics has increased.
Additionally, it was pointed out that effective reflection of scientific knowledge in policies requires strengthening cooperation between researchers and policymakers, easy-to-understand dissemination of scientific information, and promotion of international knowledge sharing.
The survey results are expected to be utilized as important reference materials for strengthening the scientific foundation of Japan's future climate change policies and international policy coordination.
