Fighting climate change

In response to the challenge of climate change, one of the four priorities in the SUEZ roadmap for sustainable development consists of taking action for the climate and shaping a resource-rich future. How? By developing new growth models that consume fewer resources and emit less CO2.
Our commitments

Ambitious new commitments to be in line with the IPCC 1.5°C trajectory

There is an urgent need to step up the mobilization against climate change. That is why, in September 2019, SUEZ strengthened its commitments to comply with the 1.5°C trajectory recommended by the IPCC.

Our commitments

  • Reduce CO2 emissions by 45% by 2030
  • Save our industrial and city authority customers 20 million tonnes of CO2 per year in 2030
  • Propose 100% sustainable solutions to our customers by 2030, i.e. solutions with a positive environmental footprint in terms of CO2, water and biodiversity.
Our solutions

Protect the climate

SUEZ solutions aim to further the efforts to reduce the carbon footprint of the Group and its clients, adapt to the consequences of climate change on water, promote material recycling, recovery and reuse, and develop climate-responsible models.

Adapt to the effects of climate change on water

By 2035, 40% of the world's population will live in water-stressed regions, including countries and cities in Asia. This is one of the main consequences of climate change. Without water, there can be no development, food, agriculture or health. SUEZ is committed to saving water through the improved control of leaks and consumption, and to maximizing the offer by increasing the available volumes of alternative water (re-use of wastewater, desalination).
SUEZ provides industry with solutions to limit its water footprint
and is working to raise awareness of the consequences of climate change on water through the Business Alliance for Water and the Climate. Preventing is as important as adapting. SUEZ develops predictive tools to prevent the risk of flooding for local authorities, irrespective of their size.

  • Systematically offer to our customer plans of resilience to the effects of climate change
  • Promote the different usages of water by multiplying by 3 our alternative water production capacity by 2030
  • Save the equivalent of the water consumption of a city of more than 2 million inhabitants


In Asia, we contribute to these objectives through our Sustainable Development Targets for 2021. As of 2019, we have saved the equivalent of water consumption of more than 640,000 inhabitants.

We also optimize our water supply efficiency through various means to lower our non-revenue water rate. Our subsidiary, Macao Water, has been providing drinking water services to Macau, and applied our patented AQUADVANCED® Smart Network performance system to monitor water supply flow, hydraulic pressure, water quality and energy consumption, predict operational risks as well as improve the water supply system.  Together with operational measures, enhanced leakage inspection, renovation of networks and meters and valves upgrades in place, Macao Water has significantly reduced the non-revenue water rate from 18.1% in 1985 to 7.5% today.

Promote material recycling, recovery and reuse

Every one of SUEZ’s employees is working to shape a sustainable environment. Shifting the Group’s activities towards the circular economy is the most effective means of achieving this end.
The circular economy disconnects growth from the consumption of natural resources while also reducing GHG emissions. The Group is renewing its goal to increase the proportion of waste turned into secondary raw materials and is making this goal worldwide in scope.

  • Increase the production of secondary raw materials by 20%
  • Achieve a ratio of 2 tonnes of waste for reuse, for every tonne of waste that is disposed of


In Asia, we have produced over 360,000 tonnes of secondary raw materials for reuse in 2019.  These include managing sorting, crushing and sifting construction and demolition waste for integrated use in Changshu, Mainland China, as well as operating a glass crushing facility where the recycled glass sand is an input in roads in Macau.

Building climate-responsible models

The fight against climate change and the large-scale deployment of the circular economy both demand the creation of a new economic model structured to take external environmental and social impacts into consideration.
SUEZ is working to develop this model by adopting an internal carbon price,
by systematically proposing a remuneration of operators indexed to global performance, by participating in efforts to develop material circularity indicators that will make the measurement of the impacts of the new model more robust.

  • Introduce a directive carbon price in 60% of the annual expenditure committed to new projects
  • Introduce a harmonised global circularity indicator for goods and services
  • Systematically offer pay packages partially index-linked to our global performance
  • Raise employee awareness and promote training in emerging models (carbon accounting, new business models, etc.)
Our projects in Asia
Our Kaohsiung Renwu Waste-to-Energy Plant treats municipal waste and generates energy from waste while meeting the world’s most stringent emission standards.  The plant effectively turns 1,350 tons of waste every day into a valuable source of 808MWh of energy whilst reducing 168,000 tons of greenhouse gas emissions per year.
We also operate Hong Kong’s first Organic Resources Recovery Centre (O·Park1), with a capacity to treat 73,000 tonnes of food waste annually. When running in full capacity, about 14 million kWh of electricity can be exported to the grid per year, which is equivalent to the power consumption by some 3,000 households. The facility can generate about 20 tonnes of compost per day as a by-product.
Our hazardous waste treatment facility in the Shanghai Chemical Industry Park (SCIP) has been providing hazardous waste incineration treatment services since 2006.  Equipped with energy recovery devices, heat generated from incineration is used to produce steam and supply to industrial companies in the park and saved 55,000 tonnes of standard coal per year.
In Suzhou Industrial Park, our sludge treatment plant is the first of its kind in Jiangsu, mainland China that implements a circular and zero discharge model.  The sludge treatment plant can achieve optimal energy recovery, water savings, material recovery and energy efficiency while converting sludge into resource.  The dry sludge is used as an alternative fuel in power generation plant that helps avoid 24,000 tonnes of standard coal per year.
