The Hangzhou 2022 Asian Games Organising Committee has pledged for a green environment at the event, creating "Zero Waste Asian Games Cells" to bring the solid waste emission of the event down.

It says it wants to bring emissions down "by over 10 per cent compared to other events", but none of these events have been listed.

Hangzhou 2022 has prepared a guideline for the implementation of the "zero-waste Asian Games" system during and afterwards in areas such as construction, catering, offices and accommodation.

These facilities are to be found across the city on the sorting of waste and helping reduce solid waste from source, plus resource utilisation and pollution-free disposal of waste in competition venues and reception hotels.

"Online data analysis enables effective early warning, timely and safe disposal of wastes, and precise evaluation of work results, and will greatly contribute to carbon neutrality during the Asian Games," said Hangzhou 2022 in a statement.

China is the biggest polluter in the world, emitting 10,065 million tonnes of carbon dioxide in 2019, nearly double that of second-highest, the United States.

The Hangzhou 2022 Asian Games are scheduled to take place from September 23 to October 8 2023, having been postponed by a year due to COVID-19 restrictions in China.
