In 2003, the Casino Group set out its commitments to combat climate change, reduce pollution, and preserve natural resources and biodiversity. It reaffirmed its commitments by signing the United Nations Global Compact in 2009 and by launching a CSR continuous improvement programme, which lays down the Group’s environmental priorities.
In order to further this process, in 2012 the Group strengthened its organisational structure with the creation within the CSR department of an Environment department in charge of coordinating the Group’s environmental priorities, sharing good practices and monitoring action plans.
Each Group entity is responsible for implementing the organisational structure and action plans necessary at local level to achieve the predefined objectives.
The stores’ environmental priorities are to:
- reduce greenhouse gas emissions;
- improve energy efficiency;
- reduce and recover waste.
A low-carbon strategy against global warming
In 2012, the Casino Group undertook to reduce its greenhouse gas emissions (Scopes 1 and 2) per square metre of retail space by 20% by 2020.
Measuring greenhouse gas emissions
The Group has standardised carbon-reporting practices since 2012, to compare the subsidiaries’ inventories and to identify the most efficient practices.
The main sources of emissions in the Group’s operating scope are:
- fugitive emissions from refrigeration systems, which account for more than 50% of Scope 1 and Scope 2 emissions;
- emissions related to the production of the energy consumed by stores;
- emissions from the combustion of fuel needed to transport goods.
The Group’s subsidiaries carry out a greenhouse gas emission inventory for Scopes 1 and 2 every year to check that their reduction plans are in line with the Group’s emissions reduction objectives.
Reducing fugitive emissions of réfrigérants
The Group’s top priority is to reduce emissions resulting from refrigerant leaks, which contribute significantly to the global warming generated by commercial refrigeration units. In partnership with ADEME, the Group published a guide to low-carbon commercial refrigeration for its technical teams in 2015.
The main initiatives implemented serve to:
- strengthen containment systems of existing facilities. The goal is to reduce leakage through improved prevention and the implementation of facilities with better sealing;
- increase the proportion of fluids with low global warming potential (hydrocarbons, CO2, NH3) in new facilities. The Group promotes solutions that do not contain HFC. In France, six Casino supermarkets and 15 Monoprix stores use CO2 as a refrigerant for frozen storage (subcritical facilities). These banners also commissioned facilities for refrigerated and frozen storage using CO2 (transcritical facilities). In Brazil, GPA has begun the process on subcritical facilities.
In 2016, web seminars were organised with the technical teams to define the terms governing transfers to low-carbon technologies for commercial refrigeration, and a forum was organised by GPA in Brazil with low-carbon refrigeration experts, retailers and the Brazilian government, with support from the Consumer Goods Forum.
Reducing emissions generated by the transport of goods
The Group’s second priority is to reduce emissions from goods transport.
The main levers are:
- reducing kilometres travelled;
- increasing loads carried per delivery;
- promoting means of transport other than road with lower greenhouse gas emissions (rail, inland waterways);
- improving the fleet of vehicles (CNG, hybrid, Euro VI);
- training in eco-driving.
In France, Franprix has increased the proportion of goods it delivers to stores located in the Paris city centre via the Seine by 42%. It is also continuing work to modernise its fleet of lorries in compliance with the Euro VI directive. Monoprix is gradually upgrading its fleet of natural gas vehicles to bio NGVs to reduce the carbon footprint of deliveries in Paris. Casino makes 98% of its deliveries in the city centre with lorries complying with the latest air pollution standards (Euro V and VI) and equipped with silent cooling systems. In 2016, Casino announced the deployment of a fleet of natural gas vehicles for store deliveries. The new vehicles will emit less CO2 and cut particulate emissions by 85%. The aim is to have about 400 vehicles operating by 2020. To increase lorry-loading capacity, Casino whenever possible provides stores with stackable handling solutions to load lorries on two levels, avoiding the use of double deck lorries.
Outside France, GPA remains committed to its backhauling programme and its policy of upgrading transport vehicles to lorries emitting less CO2 and fine particles, as well as testing the use of double-deck trailers to increase delivery loads and reduce mileage to deliver stores.
In Colombia, Éxito has reduced its mileage by increasing the load capacity of its vehicles, and has centralised the coordination of import flows to optimise container fill rates.
