Climate change

Climate change is the biggest environmental challenge for the world. Long-term success in the food business and the success of the supply chain depend on the quality of the environment. At Tesco, we are aware of our responsibility in caring for people and the planet.

Therefore, Tesco was the first business to set a goal of being carbon neutral by 2050. To date, we have managed to reduce CO2 emissions by 32% in Slovakia. We evaluate the progress in fulfilling our obligations according to the initial situation in 2015.

In meeting our goals, we focus on those that produce the highest volume of CO2 - electricity, cooling, distribution and heating.

Electricity and heating

  • Since 2006, we have invested in improving energy and refrigeration efficiency. We started using LED lighting, refrigerator doors, technologies to reduce the leakage of cold air from refrigerators, and we are also educating our colleagues. These initiatives have contributed to annual savings of 200,000 tonnes of CO2.
  • In 2017, we committed ourselves that by 2030, the Tesco Group will draw 100% of its electricity from renewable sources. In Central Europe, we are well on our way to achieving this goal, and in Hungary and Slovakia, certificates already confirm today that 100% of the electricity used in our stores and distribution centers comes from renewable sources. We have similar plans for Poland and the Czech Republic. Our next goal is to ensure that our demand helps increase the amount of energy produced from renewable sources.

Thanks to the transition to renewable energy sources, we will be able to decarbonise our electric heating, one of the four places where the most emissions occur.


  • In Slovakia, to this day we have managed to reduce the amount of refrigerants by 43.6%. This is the largest reduction in Central Europe.
  • In 400 plants in Central Europe, we switched to natural refrigerant gases and other gases with low global warming potential (GWP).


  • We focused on reducing the emissions produced by trucks, making maximum use of their capacity (fuller cages, fuller vehicles), reducing driving distances (fewer kilometers, route optimization), increasing fuel efficiency and testing alternative fuels (eg liquefied natural gas).
  • We use our own logistics services throughout our distribution network to minimize the number of empty vehicles on the road. These services optimize the size of the routes so that trucks can pick up the products from the suppliers and thus save them the cost of transporting the goods to our distribution centers. In 2019, we saved up to 2.1 million kilometers without cargo in this way, which represents a saving of 1.6 million kg of CO2 emissions.

We will continue to work tirelessly in our fight against climate change to ensure not only a future for our business, but also to bring about a broader positive change in working with the government to promote the sustainability principles of the industry as a whole.
