Contributing through our water and waste businesses

Preserving nature lies at the heart of our business. For more than 160 years, we have helped to preserve natural environments by treating wastewater, and to prevent pollution by collecting and upgrading waste.

At a time when climate change is increasing water stress in many communities, we are offering solutions to help people use water more efficiently and to create alternative water resources.

We are helping communities reduce their carbon emissions and achieve energy independence by producing partially renewable local energy from waste and sewage sludge.

Promoting and implementing practices that reduce consumption, more efficient technologies and circular solutions to reuse and make the best possible use of the Earth’s finite resources is central to our purpose.

Our commitment to making further progress regarding the climate, nature and society

In response to climate change, the depletion of natural resources and biodiversity loss, along with growing pressure on water resources, we want our business activities to make a greater contribution to sustainability.

This is the objective of our 2023-2027 sustainable development roadmap, which sets ambitious targets as regards fighting climate change, preserving biodiversity and acting in a socially responsible way. A year after its launch, we have already achieved tangible results, such as becoming self-sufficient in terms of our electricity consumption in Europe.

We are taking action all along our value chain. When choosing our suppliers and subcontractors – of which we have more than 43,000 worldwide – we favour those taking action to reduce their environmental footprint and increase inclusion. Specifically, we are committed to implementing action plans with our strategic suppliers to reduce greenhouse gas emissions in our value chain (Scope 3).

Our external recognitions

Our commitments were recognised in 2024 by two leading organisations in terms of assessing corporate ESG policies1: EcoVadis and CDP. In January 2024, we were awarded the EcoVadis Gold Medal – with a score of 77/100 – and a double A- rating from CDP for our climate and water stewardship commitments.

Sustainable performance through committed governance

We assess progress towards our sustainability targets according to a strict timetable, using quantitative performance indicators. Indicators are monitored by our executive management and CSR Committee.

Our CSR Committee, which is made up of Board members, validates sustainability targets, ensures that adequate resources have been allocated to achieving them, and assesses how those resources are used. It reviews progress towards the Group’s commitments several times a year. Our Executive Committee monitors that progress, performs budget oversight and approves transformative projects that will help us achieve our targets. Throughout the year, an operational steering committee meets to monitor the progress of our commitments and their implementation within our various entities.
In addition, 20% of SUEZ executives’ long-term compensation is linked to the attainment of these targets, with a focus on health and safety, reductions in greenhouse gas emissions and equal opportunities.
This approach to assessing progress forms part of a broader governance arrangement that aims to ensure that issues relating to sustainability, ethics and risk management are taken into account at all levels of the Group, and that we report on them to all our stakeholders. Our Non-Financial Performance Statement, Ethics Charter, Human Rights Policy and Vigilance Plan constitute our key reporting documents on these matters.
