China's green vision a good match for Suez

These policies mean great opportunities to companies like Suez, Clark said.

"I believe that in the next 10 to 15 years, China will become the largest environmental market. Our activities in China currently account for 10 percent of Suez's global portfolio. This number keeps growing,” he said.

"Throughout our time in China, we've been working together with our local partners in helping authorities and industrial clients develop innovative solutions for climate change and sustainable resource management," he said.

In January this year, Suez announced the acquisition of its partner NWS Holdings' non-controlling stakes in all their common businesses in China, as part of an effort for Suez to further expand its business in the country.

To date, Suez has managed 34 solid-waste projects and operated 39 water projects in China. Its smart and environmental solutions have been applied in places such as Shanghai, Chongqing, Macao, Hong Kong and Taiwan.
