Sustainable Wine Roundtable adds five new signatories to Bottle Weight Accord

Ellis Wines, Bodega Beronia, Domaine Bousquet, SAQ and Guy Anderson Wines have joined the agreement as it reviews progress towards its 2026 target.

The Sustainable Wine Roundtable (SWR) has welcomed five new members to its Bottle Weight Accord (BWA), as it publishes a progress review ahead of the 2026 target to reach an average bottle weight of 420g per 75cl bottle.

Distributors Ellis Wines and Guy Anderson Wines have signed up alongside Spain’s Bodega Beronia, Argentina’s Domaine Bousquet and the Quebec alcohol monopoly, Société des alcools du Québec (SAQ).

With these additions, the Bottle Weight Accord now covers more than 2.5 billion bottles of wine produced annually.

Progress on cutting carbon

The BWA was launched in November 2023 with the aim of reducing the carbon footprint of the wine industry by lowering bottle weights. According to SWR, the expansion of membership has significantly increased its impact.

As Research Director at SWR, Dr Peter Stanbury, said: “The central aim of the BWA was to reduce the carbon footprint of the wine industry. It has been extremely successful in achieving this. In its first year, the carbon saving was more than 144,000 tonnes. In the past year, the expansion of the Accord membership means that the carbon mitigated in 2025 was nearly 294,000 tonnes.”

The latest signings also underline the role of distributors and intermediaries in reducing bottle weights across global supply chains.

Bodega Beronia, part of González Byass, said the commitment aligns closely with its existing sustainability strategy. Victoria González-Gordon, Chief Sustainability Officer at González Byass, said: “We are fully aligned with the Bottle Weight Accord commitment, as more than 90% of our production at Bodegas Beronia uses lightweight glass. We continue to make progress in lightening our bottles, as we are aware that this is a key step in our decarbonization roadmap.”

Ellis Wines highlighted the importance of collaboration with suppliers. Ben Webb, wine buyer at Ellis Wines, said: “Our priority has been working with suppliers to reduce their environmental impact by managing their packaging weights, which directly limits CO2 emissions in manufacturing and transport. Only by working together with our partners will we reduce our environmental impact across the supply chain.”

What happens after 2026?

The SWR report also looks beyond the current 420g target. Stanbury confirmed that further research will take place next year to assess whether lighter bottles could become the new norm.

“During 2026, SWR will undertake renewed research into still wine bottle weights to understand whether a lower target figure might now be realistic,” he said. “We know already that many of our members’ wines are sold in bottles in the 350–370g range, and bottles as light as 300g are now increasingly widely in circulation.”

In March 2026, SWR will also launch a Sparkling Bottle Weight Accord. This will set weight benchmarks with an increased focus on safety, reflecting the different pressures involved across sparkling wine styles.

SAQ said joining the Accord reflects a long-standing commitment to collective action on sustainability. Marie-Hélène Lagacé, Vice President, Public Affairs, Communications and Corporate Social Responsibility at SAQ, said: “We are pleased to join this agreement, as it reaffirms our commitment to working collaboratively toward reducing our industry’s environmental footprint. We remain steadfast in our ongoing dialogue and cooperation with industry partners in pursuit of shared objectives—objectives to which we have been committed for many years.”

The Bottle Weight Accord is one of several initiatives led by the Sustainable Wine Roundtable, which has more than 130 members across the global wine supply chain and also works on sustainable viticulture, labour standards and comparative tools for packaging sustainability.
