Energy & Emissions in Our Operations
We are committed to the continuous reduction of our greenhouse gas emissions. Our Sustainability Strategy includes the reduction of our energy consumption and emissions by using renewable energy, low-carbon HGV fuels, less harmful refrigerant gases and making our store designs as energy efficient as possible.

Targets
For our own operations, Aldi UK & Ireland are aiming to achieve net zero for Scope 1 emissions (refrigeration gas, transport fuel, natural gas use in our operations) by 2035 and for Scope 2 emissions (the electricity we buy & use in our stores, distribution centres and offices) by 2030.
To track our progress to net zero, we have an interim target which has been approved by the Science Based Target Initiative:
- Aldi South Group to reduce operational greenhouse gas emissions by 26% by end of 2025 (vs 2016 baseline).
We know these are ambitious targets and we have a long way to go but we’ve started our journey and are working hard to be Better Everyday!
Our Operational Emissions (Scope 1 & 2)
2025 CO2 Emissions
(Scope 1 & 2 Market Based)
In 2025 our Scope 1 & 2 emissions were 81,900 tCO2e, this was a 29% reduction vs 2021.
What We’re Doing
These are some of the activities we’ve been working on to reduce our energy and emissions from our own operations:
Electricity & Renewables
- 100% of the electricity we directly purchase is green, generated by renewable sources via the REGO certification method.
- Installing doors on our store fridges in all new and refurbished stores to reduce the amount of electricity used by up to 20% compared to fridges with no doors, keeping our products cool and our customers a bit warmer at the same time.
- Installing solar panels on all new stores. We already have solar panels on over 400 stores and all 11 UK distribution centres, that’s a total of over 100,000 panels!
- All new and refurbished stores have LED lighting throughout the sales area including in chillers and chest freezers. LED lighting uses up to 60% less energy than older traditional lighting.
- 9 of our UK distribution centres are part of the Climate Change Agreement scheme which sets us energy reduction targets for refrigeration.
Gas
- Replacing gas heating where possible with electric, such as Air Source Heat Pumps.
- Converting our existing store refrigeration systems from HFC refrigerant gases such as R407f, which have a higher global warming potential (c.1,800) to CO₂, which has a global warming potential of 1.
Fuel
- Transitioning our company cars to electric; over 70% of our Regional company car fleet is now electric!
- Making the switch from diesel to lower-carbon alternative fuels like CNG and HVO for our HGVs, these fuels emit up to 80% less CO₂ than diesel.
Water
- Since launching our Water Strategy in 2022, we’ve implemented a range of initiatives to reduce water use across the business. These include site audits, leak detection, and repair inspections.
- Along with all our UK distribution centres, we have also rolled out Automatic Meter Readers across over 70% of our stores, giving us real-time data and insight into our usage, allowing us to gain a better understanding of consumption patterns and to quickly identify opportunities for reduction.
- All new distribution centres are equipped with rainwater harvesting and truck-wash recycling systems as standard. Currently five sites have rainwater harvesting in place, and nine use recycled water for vehicle washes.
- These efforts have so far contributed to a 7% reduction in water per m2 (2025 vs 2022 Baseline)
Colleague Engagement
Encouraging our colleagues to be as energy-efficient as possible in the key areas we use energy (refrigeration, lighting, heating, fleet diesel and electrical appliances) via our ‘Greener Everyday’ engagement programme and our ISO 50001 energy management system.
