Lidl's Climate Paradox: How Cutting Operational Emissions by 45% Still Left Its Footprint Rising

There is a number in Lidl's Sustainability Report 2025 that looks like an unambiguous success, and another, a few pages later, that quietly undoes the celebration. The first is 45.6 percent — the reduction in operational greenhouse gas emissions, covering Scopes 1 and 2, that the discounter has achieved since 2019. The second is 153,971,514 tonnes of CO₂ equivalent: the company's total carbon footprint for 2025, a figure that has not fallen in step with the operational gains but has instead climbed higher than in any previous year the report tracks. Read together, the two numbers describe the defining tension of climate action in food retail. A company can do almost everything right inside its own four walls and still watch its overall emissions rise, because the overwhelming majority of them were never inside those walls to begin with.

This is the Scope 3 paradox, and Lidl — part of the privately held Schwarz Group and one of the largest food retailers in Europe, with more than 13,000 locations across 32 countries and over 386,000 employees — is an unusually clear illustration of it. The Sustainability Report 2025 does not hide the arithmetic. It lays out, in a detailed carbon-footprint table prepared according to the GHG Protocol, exactly where the company's emissions come from, how they have moved over time, and why the operational progress that dominates the headlines accounts for a vanishingly small share of the whole.

The report frames all of this not as charity but as risk management, and that framing matters for understanding why the numbers are disclosed at all. Citing the World Economic Forum's Global Risks Report 2025, Lidl notes that extreme weather events rank among the most significant global risks of the century, and it draws an explicit line from a warming, acidifying ocean and more frequent flooding to the stability of the food chains its business depends on. The company points out that climate change is a social as well as an environmental threat — referencing the World Health Organization's estimate that preventable environmental risk factors are associated with some 1.4 million deaths a year in the EU alone — and that farming and fishing communities in the Global South, often the source of the goods on Lidl's shelves, are among the most exposed to lost income and food insecurity. For a retailer whose entire model rests on reliable, affordable supply, a destabilised agricultural base is not an abstract concern but a direct commercial one, and it is that self-interest, as much as principle, that runs through the report's climate chapter.

The operational story is real — and small

It is worth being fair to what Lidl has done, because the operational achievements are genuine and hard-won. Direct emissions from the company's own activities (Scope 1) and the indirect emissions from the energy it buys (Scope 2) came to roughly 915,000 tonnes of CO₂e in 2025 — about 900,911 tonnes of Scope 1 and just 14,476 tonnes of market-based Scope 2. That Scope 2 figure is the clearest evidence of what a determined procurement strategy can do. As recently as 2019 the same market-based measure stood at 878,042 tonnes; by 2025 it had collapsed to a fraction of that, because since 2022 Lidl has procured almost exclusively renewable electricity and generated a growing slice of its own.

The report puts the renewable share of total energy consumption at almost 100 percent for 2025, split between 93.7 percent purchased renewable energy and 6.2 percent self-generated, largely from photovoltaics. Lidl has installed PV systems on 4,090 of its properties, with a total installed capacity of 586,105 kilowatts-peak, and has been building out solar internationally since 2016. Total energy consumption actually fell year on year, from around 10,142 gigawatt-hours in the 2024 fiscal year to about 9,998 gigawatt-hours in 2025, while energy intensity dropped from roughly 717 to 691 kilowatt-hours per square metre of sales area.

The efficiency measures behind those figures are the sort of unglamorous engineering that rarely makes news but genuinely moves emissions. Heat pumps are now fitted in more than 7,700 buildings — 59 percent of the estate, including 7,650 stores, 86 logistics centres and 25 national headquarters. Some 4,591 buildings, or 35 percent of the portfolio, carry recognised green-building certification such as EDGE, BREEAM, LEED or DGNB, with 128 added in the reporting year alone. Natural refrigerants like ammonia, CO₂ and propane now account for 64.4 percent of refrigerant refill volume, and are used in 71 percent of logistics centres, helping cut volatile refrigerant gases by 21 percent since 2019. On the road, Lidl ran 100 battery-electric trucks across 18 countries during the reporting year, with Lidl Netherlands operating more than 80 and Lidl Sweden reporting fossil-free store deliveries since February 2025.

None of this is trivial, and taken on its own it would tell a flattering story. But here is the uncomfortable proportion the report makes unavoidable: those combined Scope 1 and 2 emissions of around 915,000 tonnes represent roughly six-tenths of one percent of Lidl's total footprint. Strip out everything the company most likes to talk about — the solar panels, the heat pumps, the electric trucks — and you have addressed less than one percent of the problem.

Where the other 99 percent lives

The rest sits in Scope 3, the emissions embedded in Lidl's value chain rather than its own operations. In 2025 that came to 153,056,127 tonnes of CO₂e, or about 99.4 percent of the company's entire carbon footprint. And unlike the operational line, Scope 3 has been moving in the wrong direction. The report sets a Scope 3 base year of 2022 — earlier figures are only partially comparable because of a methodological overhaul — and against that baseline of 127.8 million tonnes, the 2025 total represents an increase of nearly 20 percent in three years.

The report is candid about where the weight lies. By far the largest single category is purchased goods and services, at 116,348,832 tonnes in 2025 — roughly 76 percent of all Scope 3 emissions and about three-quarters of Lidl's entire footprint. This is the carbon of the assortment itself: the meat, dairy, produce, packaged food and non-food articles that fill the shelves, together with everything it took to grow, raise, process and package them. Lidl notes that within its product range, animal products such as meat and dairy are among the most emission-intensive food categories, with agricultural processes and animal husbandry the main drivers, while non-food and electronic goods carry their own heavy burdens from manufacturing and, in the case of electronics, the energy consumed during use.

That use-phase category is where the 2025 figures contain their most striking single movement. Emissions from the use phase of sold products (Scope 3 category 3.11) more than doubled, jumping from 10,446,777 tonnes in 2024 to 22,230,330 tonnes in 2025. The report attributes this largely to an increase in activity data and to methodological refinement — Lidl divides its products into 30 groups to estimate lifespan and average energy consumption — and specifically flags that improvements in the electricity mix have not yet been reflected in the calculation because of delayed data availability. In other words, part of the jump is Lidl seeing its own emissions more accurately rather than emitting dramatically more. But that nuance cuts both ways: it is a reminder that Scope 3 figures are estimates built on assumptions and databases, and that as the measurement improves, the number can move sharply in either direction.

This is also where the choice of accounting method quietly shapes the story. Lidl reports Scope 2 on both a market-based and a location-based basis, and the gap between them is instructive. On the market-based approach — which credits the company for the renewable electricity contracts it actually buys — its 2025 electricity emissions all but vanish. On the location-based approach, which applies the average emission factor of each grid Lidl operates on regardless of contracts, the same electricity consumption carried 1,506,921 tonnes of CO₂e in 2025. The difference is not a rounding error; it is larger than Lidl's entire Scope 1 footprint, and it reflects the fact that the grids the company draws from are still far from clean even where its own contracts are green. Lidl uses the market-based figure for its headline totals, as the GHG Protocol permits, but the location-based number is a useful reminder that "almost 100 percent renewable" describes a procurement achievement more than a physically decarbonised power supply.

The remaining Scope 3 categories fill in the picture. Upstream transportation accounted for 6,849,831 tonnes, disposal and recovery of sold products for 4,656,855 tonnes, and capital goods for 1,356,303 tonnes, with smaller contributions from fuel- and energy-related activities, employee commuting, waste, business travel and downstream transport. Notably, some of Lidl's operational decisions deliberately shift emissions between scopes rather than eliminate them: when the company founded its own shipping line, TAILWIND Shipping Lines, in 2022, it moved certain transport emissions out of Scope 3 and into its own Scope 1, precisely so it could exert direct control and drive efficiency measures such as weather routing, more efficient propellers and low-friction hull coatings. It is a revealing detail — evidence that the boundary between "our emissions" and "someone else's" is partly an accounting choice, and that the honest way to read a retailer's footprint is to look at the total.

Decarbonisation by leverage

If nearly all of Lidl's emissions are created by other companies — the thousands of suppliers who grow and manufacture what it sells — then the company cannot reach its climate targets by acting alone. The Sustainability Report 2025 is essentially an admission of this, and its most consequential commitments are therefore about influence rather than direct action. The headline supplier target is precise: by the end of the 2026 fiscal year, Lidl wants the suppliers responsible for 75 percent of its product-related Scope 3 emissions to be required to set their own climate targets in line with SBTi criteria. This is decarbonisation by leverage — a single buyer using its purchasing power to push science-based targets outward across its supply base, on the logic that thousands of individual supplier decisions will ultimately matter far more than anything Lidl does to its own roofs and refrigerators.

To make that plausible, the report describes an "empowerment concept" built around three mechanisms. There is a digital supplier platform offering webinars, training materials and FAQs on calculating emissions and setting targets, and used to track suppliers' annual progress. There are live training sessions run in partnership with the WWF Climate Business Network, offered twice a year since October 2024, covering science-based target-setting and greenhouse-gas accounting. And there is the Supplier Leadership on Climate Transition (Supplier LOCT) programme, a "digital climate school" that ran six-month courses for more than 100 suppliers in a pilot between October 2024 and January 2025 and continued at the same capacity through the 2025 fiscal year. Underpinning all of it are the Schwarz Group companies' own science-based targets, which were first approved by the SBTi in September 2021 and re-approved with updated ambition in spring 2025, aligned to the 1.5°C pathway.

There is also a demand-side lever that speaks directly to the composition of the footprint. Because plant-based products are, on average, less emission-intensive to produce than animal-based ones, Lidl has set a target to raise the share of plant-sourced proteins in its range to 20 percent by 2030 — an attempt to bend the purchased-goods category downward by changing what shoppers put in their baskets, not just how it is transported. Alongside this sit smaller, place-based experiments: a "Carbon Farmers" pilot in Belgium working with ten farmers over five years on soil carbon sequestration, and a Bavarian regional-brand programme in Germany aiming to cut emissions per kilogram of milk by at least 25 percent by the end of 2026 against a 2021 baseline, with farmer bonuses tied to hitting the measures.

It is also worth understanding what is driving this level of disclosure in the first place, because it shapes how the figures should be read. The report notes repeatedly that key performance indicators for the reporting year had to be collected before the year was out in order to meet the reporting obligations arising under the EU's Corporate Sustainability Reporting Directive, and that "appropriate projection methods" were therefore used to fill the remaining period. In other words, Lidl is not disclosing a rising 154-million-tonne footprint purely out of goodwill; it is building the data machinery that European regulation increasingly demands, and some of the 2025 figures are part-projected rather than fully measured. This is not a reason to dismiss the numbers — projection is standard practice and the report is unusually explicit about it — but it does mean the year-on-year movements should be read as the output of a maturing measurement system, not a precision instrument. The sharp rise in the use-phase category is the clearest example: a company that measures its supply chain more thoroughly will, at least initially, tend to report more emissions, not fewer, and that is a pattern likely to recur across the sector as CSRD-driven disclosure beds in.

These are serious, structured interventions. But it is worth being clear-eyed about the gap between the ambition and the arithmetic. The supplier target is about coverage — getting suppliers to set targets — not yet about delivered reductions, and the timeline for those reductions to show up in Lidl's own reported Scope 3 total stretches years beyond the 2026 fiscal-year milestone. Meanwhile the absolute number keeps climbing. The report's own five-year table shows total emissions rising every year from 108.3 million tonnes in 2019 to nearly 154 million in 2025. Some of that reflects a growing business and better measurement rather than worsening performance, and Lidl is transparent about those caveats. But transparency about why a number is rising is not the same as the number falling, and on the metric that ultimately matters — total tonnes of CO₂e released into the atmosphere — the trend line in this report still points up.

Why It Matters

For a food retailer, the meaningful climate fight was never in the car park or on the store roof; it's in the supply chain. Lidl's own numbers show operational wins matter, but they're a rounding error next to the 99 percent that comes from what's on the shelves. That is the real test the Sustainability Report 2025 sets — not whether a discounter can put solar panels on its warehouses, which it plainly can, but whether it can reach back into thousands of farms and factories it does not own and change how they produce. The honest reading of this report is that Lidl has proved the first and only started the second. The supplier-engagement machinery is real, but the payoff lives in future reporting years, and until the 116-million-tonne purchased-goods line starts to bend, the headline 45.6 percent operational cut is a story about the easy 1 percent. What makes Lidl worth watching is that, as a privately held group under no shareholder obligation to publish any of this, it has chosen to show the hard 99 percent going the wrong way — and that kind of candour is exactly what the rest of the sector should be measured against.

The bottom line

Lidl's Sustainability Report 2025 is, in the end, a more useful document precisely because it refuses to let the operational good news stand alone. It shows a company that has genuinely decarbonised the part of its footprint it controls directly — nearly 100 percent renewable energy, a 45.6 percent operational cut, a Scope 2 line reduced to almost nothing — while being unflinching about the fact that this part was always the smallest. The 154-million-tonne total, and the 116-million-tonne purchased-goods line inside it, are the real measure of the task ahead. Whether Lidl's supplier-leverage strategy can turn that trend around is the question the next few reports will answer. For now, the discounter has done the honest thing that many of its larger, listed rivals still avoid: it has published the number that makes it look worse, and dared its industry to do the same.
