Carlsberg Adjusts Climate Targets After Britvic Acquisition

Carlsberg pushes key climate targets back by two years

Carlsberg Group has announced a two-year delay to its major climate milestones, shifting critical deadlines from 2030 to 2032. The decision follows the brewing giant’s acquisition of Britvic in 2025, which added nearly one million tonnes of carbon dioxide equivalent to its value chain. This represents a 16% jump in total emissions at a stroke.

The company revealed the changes on 5 March 2026 as part of “Brewing Tomorrow,” a revised environmental, social and governance programme replacing its previous “Together Towards ZERO and Beyond” framework. Despite the delay, Carlsberg maintains it has raised its ambition by switching from relative emissions reductions per hectolitre to absolute cuts across its entire footprint.

For businesses tracking corporate climate commitments, this move illustrates a tension many face. Growth through acquisition can derail carefully calibrated carbon plans. The question becomes whether to absorb the setback and adjust timelines, or push ahead regardless of commercial reality.

Britvic deal transforms Carlsberg’s emissions profile

Britvic entered Carlsberg’s portfolio as the brewer’s second-largest acquisition in its history. The soft drinks manufacturer brought established brands and production facilities, but also substantial carbon liabilities. Soft drinks now account for roughly 30% of Carlsberg’s product mix, fundamentally changing the business profile.

Before the deal, Carlsberg had made notable progress. Between 2015 and 2022, the company reduced relative value chain emissions per hectolitre from 56 kg to 47 kg of CO2 equivalent, a 16% improvement. Absolute emissions held steady at around 5.5 million tonnes despite business expansion, demonstrating effective decoupling of growth from carbon output.

The original framework targeted zero carbon emissions at breweries by 2030 and a 30% relative reduction across the value chain. Net zero across all operations was scheduled for 2040. Britvic arrived with its own science-based targets, including a 50% cut in operational emissions by 2025 and carbon neutrality by 2050. By 2023, the company sourced 59% of its manufacturing energy from renewable sources.

However, integrating Britvic’s footprint meant absorbing its carbon burden. The one million tonne addition pushed Carlsberg’s total value chain emissions up sharply. This created an immediate challenge: maintain the original 2030 deadlines and risk missing them publicly, or acknowledge the changed circumstances and reset expectations.

New programme retains net zero commitment but shifts interim goals

The revised “Brewing Tomorrow” programme keeps the 2040 net zero target unchanged. Carlsberg has realigned its approach around four pillars: Cutting Carbon, Protecting Nature, Empowering People, and Inspiring Choice. The shift from relative to absolute emissions targets represents a more stringent test, removing the ability to hide growing emissions behind improved efficiency ratios.

Absolute targets require total emissions to fall, regardless of production volumes. Relative targets, by contrast, measure emissions per unit of output. A company can hit relative targets while still increasing overall emissions if it grows fast enough. The Science Based Targets initiative, which validates corporate climate plans against Paris Agreement goals, increasingly favours absolute metrics for transparency.

Carlsberg’s 2024 baseline shows the scale of the task. Scope 1 emissions, from direct operations, totalled 331,000 tonnes of CO2 equivalent. Scope 3 emissions, from the value chain, reached 7.832 million tonnes. That puts 85% of the footprint upstream, in areas like raw materials, packaging, and logistics. Total emissions stood at 8.463 million tonnes, significantly higher than 2023 due to improved reporting methods as much as actual increases.

Consequently, the company faces pressure on multiple fronts. Brewery emissions must reach zero by 2032 instead of 2030. Value chain cuts must meet Science Based Targets initiative thresholds in absolute terms. Meanwhile, Carlsberg has added commitments on regenerative agriculture, recycled materials, sugar reduction, and employee inclusion.

Organic progress continues despite acquisition headwinds

Stripped of the Britvic effect, Carlsberg’s 2025 performance shows momentum. Production site emissions fell 12% in absolute terms, bringing the total reduction since 2015 to 63%. Value chain emissions dropped 8% year on year on an organic basis, excluding the acquisition impact.

Recycled content in bottles and cans reached 51%, surpassing the original 2030 target of 50% ahead of schedule. Renewable electricity now powers 90% of operations, up from minimal levels before recent asset additions. A new biomass facility in Laos cuts 15,000 tonnes of CO2 equivalent annually, delivering an 84% reduction at that site.

These gains matter because they demonstrate underlying capability. The company has not stalled or reversed its decarbonisation work. Instead, it has absorbed a large, emissions-heavy acquisition and continued to drive down carbon intensity elsewhere. This pattern may offer a template for other firms navigating mergers while maintaining climate credibility.

Nevertheless, the delay invites scrutiny. Stakeholders including investors, regulators, and customers increasingly expect companies to hit stated targets. Moving goalposts, even for defensible reasons, risks undermining trust. Carlsberg’s argument rests on the claim that absolute targets represent higher ambition than the relative metrics it previously used.

What this means for UK businesses and supply chains

Carlsberg’s experience holds lessons for UK companies, particularly those in manufacturing, food and drink, or other carbon-intensive sectors. Acquisitions complicate carbon accounting and can derail carefully planned reduction pathways. Firms must decide whether to absorb and integrate acquired emissions or treat them separately for reporting purposes.

Moreover, the shift to absolute targets aligns with emerging regulatory expectations. The UK government’s sustainability disclosure requirements and the European Union’s Corporate Sustainability Reporting Directive both push companies toward comprehensive, absolute emissions accounting. Relative metrics remain useful for tracking efficiency, but they no longer suffice for demonstrating genuine decarbonisation.

Supply chain emissions dominate most companies’ footprints, just as Scope 3 accounts for 85% of Carlsberg’s total. This creates dependency on upstream suppliers and downstream distributors. Businesses cannot reach net zero alone. They must collaborate with partners, often including smaller firms with less capacity to measure and reduce emissions.

For SMEs supplying large corporates, this translates into growing pressure to report emissions data and demonstrate reduction plans. Procurement teams increasingly request carbon information as part of tender processes. Companies without credible answers risk losing contracts or facing exclusion from supply chains. This trend will accelerate as major buyers like Carlsberg work toward their 2032 and 2040 targets.

Packaging presents both a challenge and an opportunity. Carlsberg’s progress on recycled content shows that circular economy approaches can deliver measurable gains. UK businesses in the drinks sector face similar pressures around single-use packaging, deposit return schemes, and extended producer responsibility. Early investment in recycled materials and lightweighting can reduce both emissions and regulatory risk.

Additionally, the two-year delay highlights the importance of realistic target-setting. Overly ambitious deadlines that later require adjustment can damage credibility more than modest initial commitments that are consistently met. Businesses should model scenarios that account for growth, including potential acquisitions, rather than assuming static operations.

Five key points to note

• Carlsberg has delayed major climate milestones from 2030 to 2032 following its 2025 acquisition of Britvic, which added nearly one million tonnes of CO2 equivalent to its value chain and increased total emissions by 16%.
• The company has switched from relative emissions intensity targets to absolute reduction commitments aligned with Science Based Targets initiative standards, covering Scope 1, 2, and 3 emissions across its expanded portfolio.
• Organic performance in 2025 showed continued progress, with production site emissions down 12% and value chain emissions falling 8% excluding the acquisition impact, while recycled content in packaging exceeded the original 2030 target early.
• Scope 3 emissions, primarily from upstream raw materials and packaging, account for 85% of Carlsberg’s total footprint, highlighting the critical role of supply chain decarbonisation in achieving net zero by 2040.
• The revision demonstrates the practical challenge of maintaining climate commitments during major acquisitions, particularly for UK businesses facing similar growth and decarbonisation pressures in supply chains and procurement.

Consider how acquisitions affect your carbon baseline

UK businesses planning growth through acquisition need to assess carbon implications early in the deal process. Due diligence should include detailed emissions analysis, not just financial and operational review. Understanding a target company’s footprint before completion allows for realistic integration planning and avoids post-deal surprises.

Companies with existing climate commitments should model how acquisitions affect their ability to meet targets. A significant purchase may require baseline recalculation or, as Carlsberg found, timeline adjustments. Transparency matters here. Stakeholders generally accept honest reassessment more readily than missed targets explained retroactively.

Furthermore, businesses should evaluate whether to pursue Science Based Targets initiative validation for their climate plans. The initiative provides external credibility and ensures alignment with climate science. However, it also locks companies into rigorous reporting and limited flexibility. For firms expecting significant structural changes, this trade-off requires careful consideration.

Supply chain engagement becomes non-negotiable for companies with substantial Scope 3 emissions. Sustainable procurement programmes that work with suppliers on emissions measurement and reduction can deliver material footprint cuts while strengthening business relationships. Many suppliers welcome support with carbon accounting, which they lack capacity to do alone.

Packaging innovation offers relatively accessible wins. Carlsberg’s success with recycled content shows that circular approaches can deliver both emissions reductions and positive visibility. UK businesses should explore partnerships with packaging suppliers and waste processors to increase recycled input and design for recyclability. Extended producer responsibility regulations make this increasingly essential, not optional.

For businesses seeking structured support with carbon reporting and reduction, ESG compliance services can help navigate the complex landscape of frameworks, standards, and disclosure requirements. Getting the baseline right from the start makes subsequent target-setting and progress tracking far more manageable.
