Wine Bottle (750ml Glass)

Product Profile

The 750ml wine bottle is the global standard unit for still and sparkling wine, with approximately 20 billion bottles produced annually. A standard Bordeaux-style bottle (the most common shape) weighs 400–550g depending on wine type and regional convention — premium wines and Champagne bottles often exceed 900g. This profile uses a 400g reference weight representing a modern lightweight design.

At 0.9 kgCO2e per bottle, glass packaging sits at the heavier end of single-serve beverage containers. Aluminum cans (approximately 0.17 kgCO2e for a 330ml can) and PET bottles (0.06–0.12 kgCO2e) carry significantly lower per-unit footprints — though glass’s recyclability, taste neutrality, and consumer perception make it the dominant format for wine globally.

Why the Score Is What It Is

Glass manufacturing is fundamentally an energy-intensive melting process, and the carbon profile reflects that:

• The furnace is the dominant emission source. Glass melting requires sustained temperatures of 1,450–1,600°C. In EU glassworks, this heat is predominantly supplied by natural gas combustion in regenerative furnaces, which recover waste heat but still emit ~0.25–0.35 kgCO2/kg of glass as direct Scope 1 emissions.
• Batch chemistry contributes significant process CO2. The decomposition of soda ash (Na2CO3 → Na2O + CO2) during melting releases CO2 chemically, independent of energy source. Even a fully electrified furnace would still produce ~0.15–0.20 kgCO2e/kg from batch decomposition.
• Cullet (recycled glass) dramatically reduces both. Each 10% increase in cullet rate reduces melting energy by approximately 2.5% and eliminates the batch decomposition emissions for that fraction. EU average cullet rates (~76% for green glass, ~42% for flint/clear) are among the highest globally; US rates (~33%) and China rates (~20%) result in materially higher per-bottle footprints.
• Bottle weight is a primary lever. Moving from a 550g premium bottle to a 400g standard bottle reduces per-bottle emissions by roughly 27% proportionally.

Scope Breakdown Detail

Scope	kgCO2e	% of Total	Key Drivers
Scope 1	0.35	39%	Natural gas furnace combustion, batch decomposition CO2
Scope 2	0.18	20%	Forming machines, annealing lehr, compressed air, IS machine
Scope 3	0.37	41%	Silica, soda ash, limestone supply; transport of batch materials and finished bottles
Total	0.90	100%

Scope 1’s elevated share (39%) is unusual relative to most manufactured goods and reflects glass manufacturing’s fundamental reliance on direct combustion for process heat. Electrification of furnaces — now commercially piloting at facilities in the EU — would shift this into Scope 2 and enable decarbonization via renewable electricity.

Geographic Sensitivity

Manufacturing location has a pronounced effect on Scope 2 emissions and modestly affects Scope 3 (transport of batch materials):

Region	Approx. kgCO2e/bottle	Notes
EU (average)	0.85–0.95	High cullet rates, cleaner grid, efficient furnaces
USA	1.0–1.2	Lower cullet rate, mixed grid, older furnace stock
China	1.1–1.4	Low cullet rate, coal-heavy grid
EU (100% recycled glass)	0.55–0.65	Maximum cullet scenario

Reduction Pathways

• Lightweighting: Each 10g reduction in bottle weight saves approximately 0.02 kgCO2e. Many wine regions have moved to 400g standard bottles from legacy 550g designs.
• Cullet maximization: Closed-loop glass collection (deposit systems) enables cullet rates above 90%, substantially cutting furnace energy and batch decomposition.
• Furnace electrification: Hybrid electric-gas and fully electric furnaces are now commercially available. On a renewable grid, this could reduce per-bottle emissions by 60–70%.
• Alternative formats: Bag-in-box wine (3L format) reduces packaging carbon per liter of wine by 80–90% compared to glass bottles.

Provenance Override

FEVE publishes verified EPDs for European container glass manufacturers including Ardagh, Verallia, and Owens-Illinois EU operations. These EPDs are ISO 14040/14044 compliant and verified by Bureau Veritas and SGS, and qualify as provenance overrides for EU-sourced glass. US and China sourcing lacks comparable public EPD coverage as of 2026.
