Fighting climate change

For us, fighting climate change is of the utmost importance
In our Group’s roadmap 2017-2021, we have set ourselves 13 objectives for climate

Protect the climate

SUEZ’s 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 wastewater reuse, and develop climate-responsible models.

What is climate change?

Climate change results from an increase in the temperatures of most of the earth's oceans and atmosphere. Water is the most impacted area:

  • 40% of the world's population will live in water-stressed regions by 2035 (source: UN)
  • 40% reduction in water reserves by 2030 compared with current levels (source: World Bank)

Adhere to the 2-degree target by mitigating the causes of climate change

At the Group level, SUEZ has signed up to achieve the 2-degree target. The Group is equally committed to limiting the carbon footprint of its activities in India.

In India, the company is committed to use energy in the most efficient, cost-effective, and environmentally responsible manner. SUEZ has a robust energy-management policy in India which will play a key role in maximizing profitability, strengthening its competitive position, providing value for customers with the highest service quality, and also, support its commitment towards the community.


Design and build facilities that can be run in complete safety for people and for the environment. Identify partners and contractors who can contribute to continuous improvement actions and processes must be in place to select them on the basis of their commitment to do so.


To manage energy consumption, maximize energy performance, optimize operating expenses.


Demonstrate our commitment to stakeholders and leadership in our industry by reducing environmental impacts associated with energy use.


Increasing energy efficiency and optimizing cost for our customers

  • Comply with all energy management laws of land, regulations and Codes of Practice in existing operations, upgradation and new developments .
  • Operating practices that seek to minimize impacts through works and management practices, continual improvement, training, innovation and use of new technology.
  • Increase awareness among employees and encouraging the sharing of good practices, return of experiences (REX) and international expertise
  • Prepare, monitor and review of plant-specific energy objectives and targets
  • Communication of the policy
  • Consultation with experts of SUEZ group, the supply chain, with other agencies, groups of community about energy management matters of common concern

Promote responsible behaviour and develop environmental friendly processes

Every one of SUEZ’s employees is working for the Resource Revolution. Within their area of responsibility, each manager has the duty to ensure the protection of property and the environment. Each manager is responsible for the communication and application of the rules and commitments and ensuring that messages and practices are consistent.

Each employee is aware of his / her personal role in protecting the environment and in preventing accidents. Employees are expected to deploy responsible behavior to their benefit and their co-worker.

The Sustainable Development and Risk Prevention Department establishes and ensures the deployment and continuous improvement of all Safety, Health and Environment related processes in our Omega Management system. It oversees its implementation and its effectiveness.


Making wastewater treatment plants substantially energy sufficient

SUEZ runs wastewater treatment plants in India which are substantially energy self-sufficient. To cut down on its Operation & Maintenance costs and add to the power availability in the city, these plants meet a majority of its power demand by captive biogas-based power generation engines, thus running on clean energy and reducing air pollution caused due to the discharge of Methane in the environment.

Recycling, making wastewater out of water treatment plant potable

The Wazirabad Recycling Water Treatment Plant, in New Delhi, inaugurated in 2010, uses advanced technologies to treat the wastewater of the sludge, produced by another drinking water production plant and make it fit for human consumption. Because of this, an additional 50 000 m3 per day of water, is pumped into Delhi's distribution system, benefiting more than half a million people, especially residents of the Burari area in North Delhi.


  • First of its kind plant in the country to directly produce potable water from wastewater of a water treatment plant.
  • The optimum land usage due to the use of compact technologies allowed us to save more than 30% of the land
  • Recovers greater than 90% of WTP Wastewater (Filter backwash and Clarifier Sludge) for potable use, from a nearby existing drinking water treatment plant, provides substantial savings to Delhi Jal Board (investments recovery in three years)
  • Easy maintenance with no underwater moving parts in the main clarification units
  • Fully automated SCADA-enabled plant
  • Minimized use of chemicals in the treatment plant
  • Production of Reduced Sludge Volumes (in truckable cake form) through Mechanical Dewatering using Centrifuges
