World's first global sustainability standard for glass launched for consultation

ResponsibleGlass has published the first draft of its International Standard for Glassmaking, marking a major step towards creating what it says will be the world's first global sustainability standard, certification and labelling system for the glass industry.

The draft standard is now open for a 60-day public consultation, allowing businesses, suppliers, customers, policymakers, NGOs and other stakeholders to provide feedback before the framework is finalised.

ResponsibleGlass is a not-for-profit organisation established in 2025 to maximise the contribution of glass to a sustainable society. It brings together organisations from across the global glass value chain, including manufacturers, raw material suppliers, recyclers, brands, sustainability experts and civil society organisations.

Since launching in December 2025, the initiative has grown to include 23 founding members and supporters, including glass manufacturers alongside organisations from the automotive, retail, construction and luxury goods sectors. Collectively, members employ more than 150,000 people across the glass industry and generate around $90 billion in annual revenue.

Glass is used across a wide range of industries, including packaging, construction, automotive and renewable energy. ResponsibleGlass notes that while global glass production generates around 95 million tonnes of CO₂ emissions each year, the sector has not previously had a unified international sustainability framework.

The proposed standard is intended to create an independently verifiable framework for responsible glassmaking, covering the entire value chain from raw material sourcing and energy use through to production, product design and recycling.

Glassmakers seeking ResponsibleGlass certification would undergo independent audits against requirements covering governance, responsible sourcing, environmental performance, worker welfare, community impacts and circularity.

The draft standard is built around six core areas:

• Management systems
• Responsible business practices
• Responsible sourcing
• Environmental performance
• People and communities
• Circularity and sustainable product design

Under the proposals, certified facilities would also be required to use consistent methodologies for measuring and reporting sustainability performance, including greenhouse gas emissions, recycled content and responsible sourcing. ResponsibleGlass says this would improve transparency and make it easier for customers and stakeholders to compare performance across the industry.

Glass is fundamental to modern life, from buildings and vehicles to solar technology and packaging, yet the sector has never operated under a unified, independent global sustainability framework. The publication of this first ResponsibleGlass Draft Standard is an important milestone in changing that.

ResponsibleGlass brings together the entire value chain, from raw material producers and glassmakers to customers, sustainability experts and civil society organisations, to develop a shared definition of what responsible glassmaking should look like. But a standard is only as strong as the consensus behind it. why we're now inviting the wider industry, customers, policymakers and civil society to help us build a trusted global benchmark for responsible glassmaking.

Our ambition is to create a trusted benchmark for the industry that accelerates progress on sustainability, drives transparency and helps maximise the positive contribution glass can make to a more sustainable society.

Francis Sullivan, Chair of ResponsibleGlass.

The draft framework has been developed over the past six months through collaboration between ResponsibleGlass members, technical experts and civil society organisations. Working groups focused on responsible sourcing, greenhouse gas emissions, circularity, and downstream certification and claims have helped shape the proposals.

Following the 60-day consultation, feedback will be used to refine the framework before an updated version of the standard is published, which is expected at the beginning of 2027.
