Beverage Carbon Footprint: LCA Guide for Brands (2026)

The beverage industry is under mounting pressure to quantify what it emits, not just describe what it aspires to. Major drinks companies have published net-zero pledges, yet regulators and buyers increasingly demand verified numbers behind those commitments. This guide explains how life cycle assessment (LCA) and ISO 14067 work together to produce credible beverage carbon footprint data, what the benchmarks look like, and what CSRD means for your reporting obligations.

Why the Beverage Sector Is a Priority for Carbon Accounting

Beverages touch almost every stage of the supply chain: agriculture, processing, packaging, refrigeration, and last-mile logistics. Food and beverage companies typically find that more than 70% of their emissions sit in Scope 3, making upstream ingredient sourcing and downstream packaging the dominant drivers of a product’s carbon footprint. Packaging innovation and upcycled ingredients have become two of the most active areas of reduction effort, and the rising cost of carbonation gas has turned carbon sourcing into a commercial question as well as an environmental one.

What Is a Beverage Carbon Footprint?

A beverage carbon footprint is the total greenhouse gas (GHG) emissions, expressed in kg CO₂-equivalent (CO₂e), associated with one unit of a drink across its full life cycle. That life cycle spans:

Raw material extraction and agriculture
Ingredient processing and blending
Packaging manufacture
Manufacturing and filling
Distribution and refrigeration
Retail and consumer use
End-of-life disposal or recycling

Calculating this figure requires a life cycle assessment conducted according to ISO 14040/44, with the product carbon footprint then quantified and communicated under ISO 14067.

The LCA Methodology in Brief

Life cycle assessment in the food and beverage sector has evolved considerably since its early applications, moving from simple energy audits to full cradle-to-grave models that capture water use, land use, and toxicity alongside climate impact. A standard beverage LCA follows four phases:

Goal and scope definition: decide the functional unit (typically 1 litre of finished drink), system boundary, and intended audience.
Life cycle inventory (LCI): collect primary data from suppliers and operations, supplemented by secondary databases such as ecoinvent.
Life cycle impact assessment (LCIA): convert inventory flows into impact categories, with global warming potential (GWP100) as the headline metric for carbon footprints.
Interpretation: identify hotspots, test sensitivity, and draw conclusions for product design or procurement decisions.

ISO 14067 and Product Carbon Footprints

ISO 14067 specifies the principles, requirements, and guidelines for quantifying and communicating the carbon footprint of a product (CFP). It is built on the LCA framework of ISO 14040/44 but adds specific rules for:

Allocation of co-product emissions
Treatment of biogenic carbon
Partial versus cradle-to-gate system boundaries
Third-party verification requirements

Allocation deserves particular attention: a brewery that also sells spent grain, or a winery that produces pomace, must decide how to split emissions between its main product and its by-products. And verification by an accredited third party is required before a CFP claim can be communicated externally, a step that is easy to overlook when internal estimates are already available.

Packaging: The Variable That Changes Everything

Packaging is often the single largest controllable driver of a beverage carbon footprint after the product formulation itself. A comparative LCA of PET and glass packaging demonstrates that the choice of material, combined with recycled content rates and end-of-life collection infrastructure, can shift the packaging contribution to total product emissions by a factor of three or more. The consistent finding across container types is that increasing recycled content in aluminium cans and PET bottles delivers the largest near-term reductions, while comparisons between materials hinge on contested methodological choices around recycling-credit allocation.

An analysis of LCA in food and beverage packaging published by the Life Cycle Initiative identifies data quality and comparability as the main barriers to using packaging LCAs for procurement decisions, which is why standardised methodologies matter so much.

Benchmark Data: Where Beverage Emissions Concentrate

Devera’s benchmark for a carbonated soft drink puts the median footprint of a 750 ml unit at 2.12 kg CO₂e, with packaging responsible for 42.4% of the total and raw materials (sweeteners, concentrates, water treatment) for 39.9%. The filling and distribution stages, the parts a producer most often focuses on, are a minority of the impact. For most packaged drinks the container and the ingredients, not the filling line, are where the carbon concentrates.

The dominant hotspot shifts by drink type, which is why a category average is a poor substitute for a product-specific LCA. Peer-reviewed research on brewing shows malting and packaging drive beer’s footprint, with brewhouse energy a secondary but highly actionable lever.

Drink category	Dominant carbon hotspot
Carbonated soft drink	Packaging and sweetener/ingredient production
Beer	Malting and packaging; brewhouse energy secondary
Wine	Glass bottle production and viticulture
Bottled water	Packaging and transport
Juice (not from concentrate)	Agriculture and cold chain

Because the functional unit, packaging format, and system boundary vary so much between studies, absolute per-litre figures from different sources are rarely comparable. The reliable signal is the hotspot pattern, and that is what a properly scoped LCA pins down for a specific product.

CSRD and Scope 3 Reporting Obligations

The EU Corporate Sustainability Reporting Directive (CSRD) is the most significant regulatory driver pushing beverage brands toward rigorous carbon accounting. Under the European Sustainability Reporting Standards (ESRS), in-scope companies must report Scope 1, 2, and 3 emissions, with the first wave of large public-interest entities reporting on 2024 data.

Scope 3 disclosure under ESRS E1 covers all 15 GHG Protocol value-chain categories. For a beverage brand, materiality almost always includes Category 1 (purchased goods, dominated by agricultural ingredients and packaging) and Category 11 (use of sold products, driven by the refrigeration energy of chilled drinks). ESRS E1 asks for more than an emissions total: a transition plan, reduction targets, and the calculation methodology behind each category. The recurring obstacle for food and beverage teams is agricultural Scope 3 data, where spend-based estimates have to give way to activity-based, supplier-specific figures before the numbers are defensible.

From Measurement to Reduction

A carbon footprint number is only useful if it informs action. Once hotspots are identified through LCA, the levers available to a beverage brand typically fall into four categories:

Reformulation and ingredient sourcing: switching to lower-carbon sweeteners, using regenerative agriculture-certified ingredients, or reducing water content in concentrates.

Packaging redesign: lightweighting, increasing recycled content, switching container material, or moving to refillable formats where logistics allow.

Manufacturing energy: electrifying thermal processes, procuring renewable electricity under credible power purchase agreements, and improving fill-line efficiency.

Logistics and cold chain: consolidating shipments, optimising routing, and reducing refrigerant leakage in transport and retail display units.

In practice, brands combining packaging innovation with ingredient reformulation tend to achieve the steepest absolute reductions, while those relying solely on renewable electricity procurement see more modest gains.

Frequently Asked Questions

What is a typical carbon footprint for a 330 ml can of beer? Based on published LCA studies, a 330 ml aluminium can of beer typically carries a carbon footprint of around 0.15 to 0.25 kg CO₂e, though figures vary with recycled content rates, brewery energy mix, and distribution distance.

Does CSRD require product-level carbon footprints? CSRD’s ESRS E1 standard requires company-level Scope 1, 2, and 3 disclosures rather than product-level CFPs. However, product LCAs are the most reliable way to build the Category 1 and Category 11 Scope 3 data that CSRD demands, and some downstream customers and retailers are already requesting product-level figures as part of their own CSRD compliance.

What is the difference between ISO 14067 and an LCA? An LCA conducted under ISO 14040/44 covers multiple environmental impact categories (climate, water, land use, toxicity, and more). ISO 14067 uses the same LCA methodology but focuses specifically on the climate impact, i.e. the carbon footprint, and sets additional rules for communicating that figure externally, including verification requirements.

How long does a beverage LCA take? A streamlined screening LCA using secondary data can be completed in two to four weeks. A full, verification-ready LCA with primary supplier data typically takes two to four months depending on supply chain complexity and data availability.

Can I use a cradle-to-gate LCA for CSRD reporting? A cradle-to-gate boundary excludes use-phase and end-of-life emissions. For CSRD, you need to account for all material Scope 3 categories, which for most beverages includes downstream logistics, refrigeration during use, and packaging end-of-life. A full cradle-to-grave or cradle-to-grave-with-recycling model is therefore required for complete compliance.
