Our development

Our development in Greater China

Sustainable resource management is important everywhere. But in China, it is critical. SUEZ was one of the first foreign enterprises to invest in China. Our presence in China for more than 45 years makes SUEZ a preferred partner in helping authorities and industrial clients develop innovative solutions for climate change and sustainable resource management.


Today SUEZ has more than 70 projects based on partnerships with local authorities and companies spanning Mainland China, Hong Kong, Macau and Taiwan, with over 32 million people benefiting from our water and waste services. We are recognized as one of the most influential and benchmarking environmental companies in the industry.


Moreover, China’s environmental resource concerns are unique, and we cannot rely on imported technologies from abroad to address them all. Since 2003, SUEZ has developed four R&D centres in Shanghai and Chongqing designed to develop solutions that are tailor-made for local needs.
