Over 60 nations including Japan commit to reduce cooling sector greenhouse gas emissions by 68% from 2022 to 2050


7th December 2023 – (Hong Kong) Japan has joined over 60 nations in pledging to cut 68% of greenhouse gas emissions from the cooling sector by 2050, compared to 2022 levels. The pledge was made at the 28th U.N. climate change conference, known as COP28, held in the United Arab Emirates.

The cooling sector, which includes air conditioning and refrigeration, accounts for approximately 20% of the world’s total electricity consumption. This percentage is expected to increase significantly by 2050 due to rising demand for cooling appliances, driven by global warming and population growth.

The pledge aims to address the growing concern about the impact of the cooling sector on the environment. The use of hydrofluorocarbons, a potent greenhouse gas, in cooling appliances has been identified as a major contributor to greenhouse gas emissions.

By signing the pledge, Japan has demonstrated its commitment to reducing its carbon footprint and promoting sustainable development. The country has already made significant strides in reducing greenhouse gas emissions, including a commitment to cut emissions by 80% by 2050 compared to 2005 levels.

The pledge signed at COP28 is an important step towards achieving the goals of the Paris Agreement, which aims to limit global warming to well below 2 degrees Celsius and pursue efforts to limit it to 1.5 degrees above pre-industrial levels.

Japan’s participation in the pledge highlights the country’s leadership in addressing the pressing issue of climate change. The country’s expertise in technology and innovation will be crucial in developing energy-efficient and environmentally friendly cooling solutions that can be adopted globally.
