A group of the world’s leading architecture companies have come together to develop the first global sustainability standard for the glass industry
The initiative is being led by ResponsibleGlass, a non-profit organisation established in 2025 to create a common framework for responsible glass production.
Key members include Bovis, Morgan Sindall and Waugh Thistleton Architects.
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.
Francis Sullivan, Chair of ResponsibleGlass, said: “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.”
The crucial role of glass in building design
Glass plays a vital role in building design; however, despite the industry’s importance, glass production generates around 95 million tonnes of CO₂ emissions globally each year and, unlike sectors such as steel and forestry, has never had a unified international sustainability framework.
The draft ResponsibleGlass Standard is designed to create a clear, independently verifiable framework for responsible glassmaking. It covers the entire glass value chain, from the sourcing of raw materials and energy through to glass production, product design and recycling.
Under the proposals, glassmakers seeking ResponsibleGlass certification would be independently assessed against requirements covering governance, responsible sourcing, environmental performance, worker welfare, community impacts and circularity.
Six core areas make up the glass sustainability standard
The draft standard 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.
Sustainability performance of glass will be measured from the design stage
The standard also proposes common rules for measuring and reporting sustainability performance.
Glassmakers would be required to use consistent definitions and reporting methodologies for issues such as 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.
ResponsibleGlass is now seeking feedback
ResponsibleGlass says the consultation period will play a critical role in ensuring the final draft standard reflects the views of the wider glass ecosystem.
Feedback is being sought from businesses, customers, recyclers, policymakers, NGOs and other stakeholders before the framework is ratified.
Feedback received over the next 60 days will be used to inform an updated version, which is expected to be published at the start of 2027.
Sullivan concluded: “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.”
