Through the successful application of Green Public Procurement (GPP), Shenzhen has greatly reduced the use of products that contain Ozone Depleting Substances (ODS). When emitted, ODS cause the thinning of the ozone layer, reducing the protection it offers against harmful ultraviolet (UV) radiation from the Sun. 90% of the world’s ODS are currently produced in China. Although the Chinese central government has been taking steps to phase out ODS, local governments can help accelerate the process.

The Shenzhen Municipal Government introduced more stringent regulations on public purchases and promoted newer, more environmentally friendly technology, providing a model for other cities to emulate in combating ozone depletion and climate change.

Since Shenzhen began implementing GPP in 2006, the city has eliminated 150.9 tons of ODS, as well as greenhouse gases equivalent to 1,360,863 tons of CO2. Another benefit is that the increased spending on ODS alternatives prompts more goods and services providers to stock such products, growing the market for ODS alternatives.

The case of Shenzhen showcases the significance of adopting a green public procurement approach with regards sustainable development. ICLEI (e.g. ICLEI Europe, ICLEI East Asia) offers a wealth of resources to learn more about the topic, connect public procurers, and exchange experiences through participation in networks such as Procura+.
