In Japan, over 460 municipalities, so-called “Zero Carbon Cities” along with the national government have committed to reduce carbon dioxide emissions to net zero by 2050. It aims to create ”domino effect”, in which the best performing Zero Carbon Cities knock down other municipalities to turn the whole country to be carbon neutral. Goto City, a...

Hydrogen is a potentially transformative multi-functional fuel that could help many countries achieve ambitious decarbonisation targets. High concentrations of heavy industries and rising transport emissions make hydrogen’s potential particularly enticing in Asia. However, hydrogen’s widespread deployment requires assessing multiple dimensions of...

Few challenges pose a greater threat to a healthy planet and people than air pollution and climate change. Over the past three decades, research has demonstrated that integrated solutions to air pollution and climate change can yield co-benefits that support cost-effective, coherent policies. However, research on co-benefits has yet to generate...

The global trade of solar photovoltaic (PV) products substantially contributes to increases in solar power generation and carbon emissions reductions. This paper depicts global PV product trade patterns, explores emissions reduction potential, and evaluates the impeding effect of tariff barriers on global PV product trade and emissions reductions...

This case study reports on the development of a healthcare waste management (HCWM) system at Tribhuvan University Teaching Hospital (TUTH) in Nepal where the intervention began in 2014 with support from HECAF 360, a local NGO, and Health Care Without Harm (HCWH), an international NGO, and WHO Nepal.

Between the 1990s and early 2000s, large-scale illegal dumping and improper treatment of medical waste was a common occurrence in Japan, and became a serious social issue owing to the potential human health risk and environmental damage resulting from the waste itself, which could be infectious or contained sharps or chemical and toxic substances...

In this novel and integrated MAR approach, an offsetting scheme under the concept of payment for ecosystem services (PES) is used to enhance groundwater recharge along the Shirakawa River in Kumamoto Prefecture, Japan. The scheme gives a cash incentive to farmers who pond their abandoned rice fields for groundwater recharge. For a specified period...

For cities to meet the challenge of reaching carbon neutral by 2050, one option is to promote a renovation wave for buildings. A literature review of the initiatives, standards and regulations for energy savings and the renewable energy deployment in buildings in the EU, US and Asia shows the complexity of the effort, and the need to integrate...
