[Event Report] Non-partisan Diet Member Briefing – 30-minute Health Policy Update: “Integrating Climate Change Measures and Health Promotion Measures: The Need to Formulate a National Strategy for Climate Change and Health” (May 16, 2024)
date : 6/6/2024
Health and Global Policy Institute (HGPI) held an installment of 30-minute Health Policy Update, a series of briefings for Diet members on key health policy issues. This installment was titled, “Integrating Climate Change Measures and Health Promotion Measures: The Need to Formulate a National Strategy for Climate Change and Health”.
This briefing featured a lecture from Masahiro Hashizume, Professor of Global Health Policy at the Graduate School of Medicine, University of Tokyo, and Keisuke Nansai, Director of Material Cycles Division, National Institute for Environmental Studies (NIES), on the policy challenges and necessary efforts in formulating and implementing a “National Strategy for Climate Change and Health” by integrating existing climate change measures and health promotion measures in Japan.
Sharing many questions and insights, Diet Members took the opportunity to engage in a robust exchange of opinions during the Q&A session following the lecture.
■Key Points
Health Impacts of Climate Change
- Due to the effects of climate change, the number of emergency transports due to heat stroke is expected to reach 1.7 times (compared to 1981-2000) by the middle of this century, even if strict measures against global warming are implemented. In addition, deaths due to heat stress are expected to increase 2.4 times by the middle of this century.
- There are concerns about the potential risk of infectious diseases (such as dengue fever) spreading, non-communicable diseases (NCDs), and the impact on mental health. For example, with regard to NCDs, patients with obesity and diabetes are more vulnerable to heat.
Decarbonization of the healthcare sector
- Greenhouse gas (GHG) emissions (approximately 73 million tons of CO2 equivalent in 2015) have not changed significantly in the supply chain of healthcare services in Japan, but their ratio to Japan’s total GHG emissions rose to about 6% in 2020.
- In addition, healthcare services have many emissions other than on-site emissions and electricity consumption, so decarbonization cannot be achieved by on-site actions and the introduction of renewable energy alone.
- If Japan is to achieve a carbon-neutral society by 2050, the GHG emissions (carbon footprint) of healthcare services as a whole must be reduced to net zero. With only 26 years left, it is essential to have a clear decarbonization roadmap for healthcare services, promotion and support measures, and progress monitoring, as in the UK and Australia.
