Energy & Climate

Saving energy and reducing greenhouse gas emissions are key objectives of the Migros Group. In 2017, it increased energy efficiency, replaced fossil fuels with renewable energy and built highly sustainable branches.

The Migros Group companies are steadily reducing their power consumption and greenhouse gas emissions. Most of the companies have agreed binding targets for CO2 reduction and energy efficiency with the state and cantons.

Reduction of energy consumption & greenhouse gas emissions

In order to achieve their objectives, the Migros Group companies focus primarily on saving energy. The second most important measure is the expansion of renewable energies. In addition, the companies use refrigerants with no or only very little global warming potential in their cooling systems, a measure that reduces greenhouse gas emissions from refrigerants.

Cooperative Retailing

As part of its climate and energy strategy 2020 (KES2020), Cooperative Retailing has set itself the ambitious target of using 10% less power and emitting 20% less greenhouse gases.

Cooperative Retailing

As part of its climate and energy strategy 2020 (KES2020), Cooperative Retailing has set itself the ambitious target of using 10% less power and emitting 20% less greenhouse gases between 2010 and 2020. Thus, it will save twice as much greenhouse gas emissions in this period as stipulated by the federal climate protection targets. The target of reducing energy consumption by 10% in absolute terms is also much more ambitious than the target set in the federal government's energy strategy 2050.

In 2017, Cooperative Retailing reduced power consumption in the branches and logistics enterprises since 2010 by 7.5% in absolute terms. In the same period, greenhouse gas emissions decreased by 21.2%. This reduction was due in particular to the use of LED lighting, CO2 cooling systems and building technology improvements in the branches.

Energy consumption and greenhouse gas emissions were as follows in Cooperative Retailing:

Cooperative Retailing was named a Green Cooling Leader by the Environmental Investigation Agency (EIA) for the fourth time. In 2017, Migros operated 61% of its cooperative retail stores with cooling systems using the natural refrigerant CO2, which made a considerable contribution twardso reducing greenhouse gas emissions from refrigerants.

M-Industry

As part of their overarching sustainability objectives, the M-Industry companies aim to further reduce energy consumption, cut their CO2 emissions by 20% before 2020.

M-Industry

As part of their overarching sustainability objectives, the M-Industry companies aim to further reduce energy consumption, by 6.3% before 2020 compared to 2010, and use only renewable energy sources by 2040.

This reduction was due mainly to the modernisation of cold water production and the decommissioning of a cooling system in the main cooling plant at Chocolat Frey in Buchs (AG). Thanks to compressor-free refrigeration and control improvements, power consumption can be cut by 25% or close to 1.1 GWh per year.

Promotion of renewable energy

Migros reduces its greenhouse gas emissions by improving energy efficiency; it also generates electricity using its own photovoltaic systems, and replaces fossil fuels with heat from renewable sources.

Migros uses solar energy

Migros is a pioneer and Switzerland's biggest producer of solar power. At the end of 2017, the Migros Group owned 280 photovoltaic plants with an installed output of 27'832 kWp.

M-Industry replaces fossil fuels

Since 2017, two M-Industry companies have been operating a wood-fired heating plant to generate heat.

M-Industry replaces fossil fuels

Since 2017, two M-Industry companies have been operating a wood-fired heating plant to generate heat.

The system at Jowa in Gränichen (AG) ensures a continuous supply of process heat in the two production buildings, and provides 66% of the energy needed by the entire site. Natural gas continues to be used for energy peaks. With the wood-fired heating plant, CO2 emissions can be reduced by close to 3'000 t in comparison with the use of fossil fuels.

At its Estavayer-le-Lac (FR) site, Elsa uses woodchip heating to generate steam to heat-treat milk; Switzerland's biggest wood-chip furnace for process heat cuts CO2 emissions by around 8'000 t per year. Both systems made a considerable contribution to achieving the overarching sustainability objectives of M-Industry.

Plus-energy branches

In 2017, Migros operated three supermarkets and specialist markets that produce more energy than they consume over the course of a year. These plus-energy branches, as they are known, are located in Zuzwil (SG), Pfungen (ZH) and Amriswil (TG). The concept is based on an intelligent combination of energy efficiency measures and the production of solar power by means of PV systems on the roofs.

In the reporting year, the newly opened Migros plus-energy branch at Aachtal, Amriswil (TG) received the PlusEnergieBau Diploma from the Swiss Solar Agency. The branch produces 39% more energy than it consumes over the course of a year. Cooperative Retailing is steadily transferring the concept of the plus-energy branch to more supermarkets and specialist markets.
