Our commitments to nature and preserving biodiversity

As of today, our ecosystems are vulnerable. In this context, the preservation of biodiversity is essential for climate regulation, with an economic impact on the ecosystem services it provides. The Nature pillar is a key component of our Roadmap. The Group plays a pivotal role in preserving water resources and managing recycling and reuse. Responding to the nature emergency will be a difficult journey, but we are 100% committed to it.
Our commitments

Preserve biodiversity and natural resources wherever we operate

Our "Nature" approach is based on 3 levers and 10 commitments:

Preserving resources




Limit our impact on fresh water

Number of water contracts with a water  efficiency program / total number of drinking water services

Systematically propose (100%), for all drinking water service contracts, a water savings program up to 10% of the volume over 5 years by 2027

Number of water distribution contracts in water stress areas covered by a water savings program

Propose a water savings program for 100% of our water distribution contracts in water stress areas by 2027

Support recycling and reuse

Sorting efficiency (1)
Tons recovered

Improve SUEZ sorting efficiency (1) by 2027

Growing nature regeneration capacities of SUEZ




Grow nature regeneration capacities of SUEZ

Turnover generated by solutions identified as regenerating and number of new solutions created

Create and develop existing and new SUEZ business models and solutions to accelerate natural environment regeneration and preservation by 2027

Addressing the pressures on biodiversity




Roll out Nature action plans at all priority sites managed by SUEZ

% of priority sites where biodiversity action plans are deployed and implemented

Roll out Nature action plans at 100% of priority sites managed by SUEZ by 2027

% of commercial proposals (in Nature priority zones) that include an offer towards biodiversity preservation and biomonitoring (3)

Systematically propose an offer (1) regarding biodiversity preservation when the site is in a biodiversity priority zone (3) from 2023

Prevent the development:
a) of microplastics
b) of micropollutants in natural environments

Number of proposals with microplastics and
micropollutants removing commitments / total number of WWTP proposals

Include solutions to remove microplastics and micropollutants in 100% of commercial proposals for sanitation infrastructure construction (2) (3) by 2027

Reach zero phytosanitary products used on sites managed by SUEZ

% of sites covered by the phytosanitary-free policy (Waste activities)
% of management contracts including a phytosanitary-free policy (Water activities)

Implement a phytosanitary-free policy on 100% sites operated by and owned by SUEZ with approval by the customer by 2027

Contribute to reduce the land artificialization pace

Number of hectars renatured

Annually double restored areas by 2027

Contain invasive non-native species

% of renaturation and landscaping operations using local species

Systematically use local species in renaturation or landscaping operations from 2025

Drastically reduce light pollution of installations at stake for the black corridor

% of priority sites where there is a light reduction policy deployed

Deploy the light pollution reduction
policy in 100% on priority sites (4) by 2027

Our commitments are aligned with the United Nations Sustainable Development Goals

Our actions

We are already taking actions!

Our target – 10% waste reduction in Greater Montauban

Thanks to this household and similar waste performance contract (CPDMA) in Greater Montauban, we are developing a new environmentally responsible waste prevention model, based on use rather than consumption. Supported by the French Agency for Ecological Transition (ADEME), this initiative provides multiple services: citizenawareness campaigns on waste production, creation of a recycling facility, collection and recovery of biowaste as well as the collection of illegal waste dumping.

This new business model also recognizes stakeholders and allocates the profit, factoring in:

  • the impact of performance on the overall cost of waste management (beyond the market);
  • a bonus paid or penalty applied according to whether minimum performance standards are met;
  • a proportion of the bonus allocated to the partners involved in CPDMA.

In São Paulo, we are saving water through smart networks

With its partner SABESP, SUEZ optimizes drinking water distribution by operating throughout the value chain from diagnosis and effective leak detection management to infrastructure operational capabilities, particularly through pressure and active leak monitoring as well as infrastructure renovations. The Group will also deploy a hydraulic simulation system aimed at studying and optimizing the city’s water supply.

saved in the city of São Paulo in 5 years, the equivalent of annual consumption for more than 368,000 Brazilians

In Denmark, we are innovating to recover phosphorus from wastewater

Mineral phosphorus is becoming scarce. The European Commission has now listed this resource as one of 20 “critical raw materials”. Reuse aside, it is expected to disappear in the next century. In Aarhus, Denmark, our Phosphogreen™ process extracts phosphorus from wastewater, using the struvite produced to make fertilizer. A cutting-edge technology, we estimate that Phosphogreen™ covers 20% of current global demand for phosphorus, through its recovery of wastewater. This process also reduces pipe scaling caused by struvite deposits and eliminates sand in digesters.
