Carbon Footprint of a Soft Drink 750ml: LCA Benchmark (10,000 Simulations)
Last updated: 2026-05-06
Based on 10,000 Monte Carlo simulations using the Ecoinvent 3.9.1 database and aligned with ISO 14040/44, a 750ml bottle of soft drink has a median carbon footprint of 2.1 kg CO₂e, with a mean of 2.2 kg CO₂e. The analysis draws on multiple authoritative data sources including DEFRA 2025, the Carbon Trust, and AGRIBALYSE/ADEME, and is benchmarked against 23 published Environmental Product Declarations (EPDs). Results reflect variability across production geographies, ingredient sourcing, and packaging material choices.

Key Findings
- The median carbon footprint of a 750ml soft drink is 2.1 kg CO₂e per bottle, with a mean of 2.2 kg CO₂e across 10,000 simulations.
- There is meaningful variability in outcomes: the P10 estimate is 1.5 kg CO₂e and the P90 is 2.8 kg CO₂e, indicating a spread of approximately 1.2 kg CO₂e between lower and higher-impact scenarios.
- The standard deviation of 0.5 kg CO₂e reflects significant uncertainty driven by differences in packaging material (glass, PET, aluminum), sugar sourcing (cane vs. beet), and regional energy grids.
- This benchmark is consistent with 23 published EPDs for soft drinks, lending strong external validity to the simulation range reported here.

Methodology: ISO 14040 Monte Carlo Simulation
This benchmark is derived from 10,000 Monte Carlo simulations using the Ecoinvent 3.9.1 life cycle inventory database, following ISO 14040/44 guidelines for life cycle assessment. Uncertainty ranges reflect variability in input parameters across geographies, packaging types, and ingredient supply chains, aggregated into the reported median, mean, P10, and P90 statistics.
Frequently Asked Questions
What is the carbon footprint of a soft drink 750ml?
Based on our benchmark, a 750ml soft drink has a median carbon footprint of 2.1 kg CO₂e per bottle. The range across 10,000 simulations spans from 1.5 kg CO₂e (P10) to 2.8 kg CO₂e (P90), depending on factors such as packaging material, ingredient sourcing, and the energy mix used in production and distribution.
How is this benchmark calculated?
We run 10,000 Monte Carlo simulations using the Ecoinvent 3.9.1 life cycle inventory database, in accordance with ISO 14040/44 methodology. Input parameters — including packaging material properties, sugar sourcing, energy use, and transport distances — are varied probabilistically across their uncertainty ranges. The resulting distribution yields robust aggregate statistics including the median, mean, and P10/P90 percentiles reported here. The benchmark is further validated against 23 published EPDs.
Which life cycle phase contributes the most?
Detailed phase-level breakdown data is not available in aggregate form for this benchmark. However, based on established LCA literature for soft drinks — including sources such as Amienyo et al. 2013 and the Beverage Industry Environmental Roundtable (BIER) — packaging production (particularly glass, PET, or aluminum containers) and ingredient manufacturing (notably sugar production) are typically the dominant contributors to the carbon footprint, followed by distribution and refrigeration at point of sale.
How can I reduce the carbon footprint of my soft drink 750ml?
The most impactful levers for reducing the carbon footprint of a 750ml soft drink include: switching to lower-impact packaging formats (e.g., lightweight PET or recycled aluminum over virgin glass), increasing the use of recycled content in packaging, sourcing sugar from suppliers with lower agricultural emissions, transitioning manufacturing operations to renewable energy, and optimising distribution logistics. Improving end-of-life recycling rates for packaging — aligned with EU Packaging & Packaging Waste Directive benchmarks — can also meaningfully reduce the overall footprint.
