METRO aims to improve its environmental performance in several ways. Our priorities: reduce our greenhouse gas emissions, manage our waste and reduce food waste.
Our ambition is to reduce our greenhouse gas emissions to limit global warming by focusing our efforts on key sectors over which we have direct operational control. Through these actions, we aim to contribute to the collective effort to transition to a lower-carbon economy.
Objective
In November 2023, this objective was replaced with the following five objectives, aligned with the level of decarbonization required to limit global temperature rise to 1.5°C above pre-industrial levels:
For a comprehensive understanding of our strategy and performance related to reducing our GHG emissions, as well as our methodology, please refer to our GHG Emissions Infosheet and consult our Methodology for Reporting Our GHG Emissions.

Fighting climate change
METRO remains focused on reducing its GHG emissions in order to address climate change and build resilience. We have set short‑term GHG emissions reduction targets for the entire company, aligned with the level of decarbonization required to limit the increase in global temperature to 1.5°C above pre-industrial levels.
Our decarbonization plan outlines the key measures we implement to reduce our direct (Scopes 1 and 2) and indirect (Scope 3) GHG emissions.
Our new near‑term targets are the following:
1 Scope 3 FLAG emissions are generated by the activities of the forest, land and agriculture sectors. For METRO, this means any land-based emissions and other biogenic emissions from food production activities at the agricultural level. For more information on FLAG emissions, please refer to sciencebasedtargets.org.
2025 GHG emissions details are available in our GHG emissions infosheet.
Refrigerant leaks are the single largest contributor to our direct GHG emissions. That’s why we continue to invest in a range of measures to lower the climate impact of our refrigeration systems. Our teams have adopted a proactive approach to equipment maintenance and intensified their efforts to monitor refrigeration systems to reduce leaks and refrigerant losses. In 2025, we completed 54 projects to convert systems to lower global warming potential gases, such as CO₂, and to refurbish aging equipment.
METRO recognizes that biodiversity is facing a global decline, largely due to human activities. Changes in land use, pollution, climate change and population growth threaten biodiversity, which is essential to the functioning and resilience of ecosystems and therefore vital to human health and well-being.
Our Biodiversity Statement defines our criteria and recommended practices according to four priority environments where our operations can have an impact.
Our ambition is to avoid sending waste generated by our activities to landfill with the view to achieving zero waste at our locations, representing a diversion rate of at least 90%. We intend to enhance our performance by mobilizing our teams to optimize our operational practices.

Our waste management program aims to reduce the environmental impacts of eliminating residual materials, including GHG emissions, and facilitate their valorization.
The waste objectives related to diversion are divided into two targets: one for stores and one for distribution and production centres. We aim for all stores to achieve at least 50% diversion, 25% of stores to achieve 80 to 89% diversion, and 25% of stores to achieve zero waste. As for our distribution and production centres, we aim to achieve zero waste. Key to diversion are our recycling, recovery and source reduction programs.
In 2025, our overall store diversion rate reached 78.5%, reflecting an increase of more than 6% from 2024. Our distribution and production centres reached a diversion rate of 89% in 2025, an increase of 7% over 2024.

Our ambition is to ensure that food that is safe for consumption and food residue generated by our activities are not thrown away. By redistributing them to organizations or giving them a second life, we are helping to address food insecurity and reduce the GHG emissions caused by landfilled organic waste.
Objective
Since this objective came to an end in 2025, we have set ourselves a new target:

METRO adopts a new target, that applies to both our stores and distribution centres: increase the proportion of food rescued from waste by 30% by 2030 compared to 2024.
Rather than focusing on how much food is wasted, we will focus on how much can be saved before it turns into waste. This means recovering surplus food and redirecting it to its original purpose: feeding people.
Our approach is aligned with the Food Loss and Waste Accounting and Reporting Standard, which states that food is only considered to have been lost or wasted if humans do not consume it.
Through consistent efforts, we are rescuing more food from being wasted each year. We are multiplying initiatives to make the most of our food surpluses, including repurposing it in products and meals prepared in store, selling at a discount, partnerships with food rescue apps, and our food recovery program One More Bite, our flagship initiative in the fight against food waste.
