Climate Change

We invest in adopting a responsible and proactive stance, aiming to reduce the carbon footprint resulting from our activities.

We want to reduce our consumption of energy and scarce resources such as water and choose less polluting refrigerant gases, because we believe that only an efficient approach to natural resources can benefit the ecosystems.

 

ENERGY AND WATER CONSUMPTION

By being committed to efficient resource management, we are able not only to obtain savings but more importantly, to implement initiatives that aim to fight climate change.

An example of this is the project “Teams for Managing Water and Energy Consumption”, whose objective is to raise the awareness of over 30,000 employees working in our more than 450 stores in Portugal, regarding the fight against waste and the rational use of energy and water.

Between 2011 and 2016, we saved over 4 million euros, reflected in 373,393 m3 of water and 32,347,700 kWh of electricity.

In the office buildings in Portugal, we launched the project “Let’s Go Green”, aiming to encourage people to adopt more responsible best practices in their use of energy, water and paper. Between 2015 and 2016, we reduced our consumption of energy and water by 35% and 12%, respectively. We also prevented 205,000 plastic cups from being used and sent more than 30 tons of paper, 1.5 tons of used cooking oil and 2.7 tons of caps, corks and coffee pods for recovery.

 

RENEWABLE ENERGY

We invest in renewable energy systems, such as passive underground cooling/heating, the use of solar collectors for heating water, lamp posts powered by photovoltaic panels and tubular systems for transporting natural light.

These systems enabled us to save approximately 63,000 euros in 2016. This gain in efficiency meant we were able to prevent the emission of 636 tons of carbon into the atmosphere, an improvement of 26 tons compared to 2015.


LOGISTICS PROCESSES

As our core business is Distribution, we seek to reduce the environmental impacts linked to the logistics processes throughout our value chain, minimising the consumption of raw materials and energy resources and also reducing the amount of emissions and waste.

Through our backhauling programme, consisting of optimising delivery routes and maximising loads, during the return journeys, we collect empty pallets from our stores and goods from suppliers in Portugal and in Poland.

Between 2011 and 2016, we collected 6 million pallets, saving 38.2 million kilometres in journeys, the equivalent of 50 trips to the moon and back, and prevented the emission of 35.4 thousand tons of CO2.

In Portugal, 68% of the goods transport vehicles comply with the Euro 5 requirements (192 vehicles) and Euro 6 requirements (36 vehicles) proposed by the European Union. In Poland, 97% of the goods transport vehicles comply with the Euro 5 requirements (687 vehicles) and Euro 6 requirements (264 vehicles).


REFRIGERANT GASES

We believe that the effective use of refrigerant gases is essential for minimising their impact on climate change. That’s why we’ve been heightening the control of leaks in conjunction with our partners, by using more efficient technologies:

  • In Poland, we installed cooling systems with thermal roll-containers with CO2 snow in the 15 Distribution Centres (DCs). In Portugal, the same system is in operation in the Algoz DC;
  • We have installed cooling technologies (10 stores in Portugal and 2 stores and 2 DCs in Poland) which run exclusively on CO2;
  • We have 5 DCs with refrigerated warehouses (positive and/or negative cold) with systems running on ammonia combined with glycol;
  • We have 582 stores with freezers that use only propane;
  • In Poland, in the centralised cooling system of 700 stores, we replaced 404a refrigerant gas with R407f gas, giving rise to a reduction of more than 50% with regard to GWP – Global Warming Potential.
  • In Poland, we replaced the refrigerant gas in 264 lorries, giving rise to a reduction in GWP of almost 50%. 3 of our lorries already use CO2 as a refrigerant gas.


CARBON FOOTPRINT

In 2016, our carbon footprint stood at around 1.3 million equivalent tons of CO2, an increase of 17.2% compared to 2015, which can be justified mostly by the significant growth in the market-based* emission factors linked to electricity consumption. This reality was also reflected in the increase of carbon emissions calculated for every thousand euros of sales, notwithstanding the 1.6% reduction in the specific consumption of electricity.

*carbon emissions released by the electricity producer when generating energy. The greater the proportion of electricity produced through renewable sources, the lower the carbon content of the kWh supplied.
