ResponsibleGlass has published the first draft of what it says is the world’s first global sustainability standard for glassmaking, opening a 60-day public consultation on the framework.
The not-for-profit organisation was established in 2025 to create an international sustainability standard, certification scheme and labelling system for the glass sector. It brings together glass manufacturers, suppliers, recyclers, customers, sustainability experts and civil society organisations.
Since launching in December 2025, ResponsibleGlass has grown to include 23 founding members and supporters. Collectively, they employ more than 150,000 people and generate around $90 billion in annual revenue.
The proposed standard covers the entire glass value chain, from raw material sourcing and energy use to manufacturing, product design and recycling. It aims to create a consistent and independently verifiable framework for responsible glassmaking.
Glass production is estimated to generate around 95 million tonnes of CO₂ emissions globally each year. ResponsibleGlass says the sector has lacked a unified international sustainability framework despite its role in construction, transport, packaging, solar energy and advanced technologies.
The draft standard is built around six core areas: management systems, responsible business practices, responsible sourcing, environmental performance, people and communities, and circularity and sustainable product design.
Under the proposals, glassmaking facilities would undergo independent audits and be assessed on criteria including responsible sourcing, environmental performance, worker welfare, transparency and circularity.
The framework also introduces common rules for measuring and reporting sustainability performance, including carbon emissions, recycled content and responsible sourcing.
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.”
Feedback from businesses, policymakers, recyclers, NGOs and other stakeholders will be used to refine the standard before an updated version is published in early 2027.
