Global glass sustainability standard opens for consultation
ResponsibleGlass has published the first draft of its International Standard for Glassmaking.
The proposed standard aims to do for glass what organisations such as FSC have done for forestry and ResponsibleSteel has done for steel - creating a globally recognised framework that allows glassmakers to demonstrate independently verified sustainability performance.
Under the proposals, glassmaking facilities would undergo independent audits, with certified companies able to demonstrate compliance against a single internationally recognised benchmark for responsible glassmaking.
The standard also proposes common rules for measuring and reporting sustainability performance. Glassmakers would be required to use consistent definitions and reporting methodologies for carbon emissions, recycled content and responsible sourcing, making it easier for customers and stakeholders to compare performance across the industry. These requirements would form the basis of a certification and labelling system for responsibly produced glass.
The draft standard is now open for a 60-day public consultation, giving businesses, suppliers, customers, policymakers, NGOs and other stakeholders the opportunity to help shape its development.
It is structured around six core areas:
- Management systems – ensuring companies have the policies, and reporting systems needed to manage sustainability performance effectively.
- Responsible business practices – including legal compliance, anti-corruption measures, stakeholder engagement, transparency and public reporting of sustainability data.
- Responsible sourcing – requiring companies to understand and assess the environmental and social impacts of key raw materials, recycled materials and energy sources used in glass production, while promoting greater supply chain transparency. This includes everything from silica sand and soda ash through to recovered glass and energy inputs.
- Environmental performance – covering greenhouse gas emissions, energy use, water stewardship, biodiversity, waste management, air emissions and pollution, with companies expected to measure, manage and disclose performance against key sustainability metrics.
- People and communities – including worker health and safety, labour rights, human rights and engagement with local communities affected by glassmaking operations.
- Circularity and sustainable product design – encouraging greater use of recycled materials, improved recycling and recovery rates, and the development of glass products designed to reduce environmental impacts both during use and at the end of life.
Despite glass being one of the world's most important industrial materials, the sector is responsible for around 95Mt of CO₂ emissions each year, yet has never operated under a unified global sustainability framework.
ResponsibleGlass is a not-for-profit organisation established in 2025 to maximise the contribution of glass to a sustainable society. The initiative brings together organisations from across the glass value chain, including glass manufacturers, raw material suppliers, recyclers, brands, sustainability experts and civil society organisations.
The consultation is open until 18 September 2026.
