Why It Exists
Why do we need ResponsibleGlass?
Sustainability claims in the glass industry are inconsistent and hard to compare today — a credibility gap that makes it difficult for customers, regulators and investors to tell genuine progress from marketing. ResponsibleGlass closes that gap with a shared, trusted benchmark the whole value chain can measure itself against. It’s not a new idea: multi-stakeholder sustainability standards already exist and work well in other sectors, such as forestry (FSC) and steel (ResponsibleSteel) — ResponsibleGlass brings that proven model to glass.
At the same time, the pressure to act is real and growing. Regulations like the EU’s Corporate Sustainability Reporting Directive are pushing companies to back up claims with verified data, not self-reporting. Major customers in automotive, construction and packaging have their own net zero targets and increasingly expect the same assurance from their supply chains.
What is ResponsibleGlass?
A global, sector-specific, multi-stakeholder sustainability standards programme for glass — bringing together the whole value chain: raw material suppliers, manufacturers, brands, automotive, construction, recycling and re-use, architects and specifiers, and civil society.
What will it achieve?
ResponsibleGlass will give the industry a credible, transparent standard for responsible production, use and recycling of glass — a clear, shared definition of what “responsible glassmaking” looks like across sourcing, production and beyond, with performance that’s measurable and verifiable. It will help companies demonstrate real progress, build trust with customers and regulators, and create a level playing field where genuine leaders are recognised for it.
How will it create value for my company?
It makes you part of a progressive community, debating and agreeing what good looks like on sustainability. It creates a market pull for higher standards, making it easier for you to get a return on your investment. It gives you a consistent, credible way to demonstrate performance to customers and regulators — instead of every company making its own claims that can’t be compared. That means staying ahead of where market and regulatory expectations are heading, not scrambling to catch up.
How will this work alongside existing frameworks (e.g. EPDs, sustainability reporting)?
It builds on what companies already have, rather than replacing it. Most companies already run reporting systems and environmental management processes — ResponsibleGlass adds consistency across the value chain on top of that, not a separate layer of requirements. Most schemes are based around the supply of data; ResponsibleGlass builds on that and sets out the standard you need to work to. It also explicitly covers all sustainability issues, not just carbon, including issues that are harder to measure, like human rights.
How is it different from other standards (e.g. FSC, ResponsibleSteel)?
It follows a proven model — multi-stakeholder standards have become the benchmark in forestry, steel and aluminium — tailored to glass and developed in line with the ISEAL Codes of Good Practice for credible standards-setting. The key difference is scope: ResponsibleGlass covers the full value chain, from raw materials through manufacturing to downstream use, rather than one link in the chain.
How will the standard be developed?
Through a multi-stakeholder process, with working groups already active on sourcing, emissions, circularity and claims/labelling. The process runs through drafting, consultation and pilot phases, so the standard is both credible and workable in practice.
Who is involved in / supports ResponsibleGlass?
Organisations from many countries and from across the value chain — raw materials, manufacturing, brands, automotive, construction, recycling and re-use, architects and specifiers, civil society. That breadth is what gives the standard its credibility: it’s being built with the industry, not done to it.
How much will it cost, and will customers pay?
ResponsibleGlass Founding Membership has a cost over the three-year period needed to develop the Standard and Assurance programme. Our members are at the heart of developing and approving the system that will benefit companies across the value chain, especially downstream glass buyers.
ResponsibleGlass is set up as a not-for-profit organisation, so 100% of the fees charged will be invested in the work of the organisation to provide value to the glass value chain and its stakeholders. Once the assurance programme is approved, glassmakers will pay a certification fee to ResponsibleGlass to cover the costs of maintaining the system, and — when available — a fee for use of the ResponsibleGlass brand and logo. The fee levels have not been agreed as yet. We believe that ResponsibleGlass certification will be valued along the glass value chain, and that customers will prefer and give preference to glass from sites that have been certified through our trusted processes.
How do you ensure ResponsibleGlass doesn't raise anti-trust concerns?
It’s focused on sustainability performance, not commercial decision-making. It’s a structured, transparent standard-setting process open to a wide range of stakeholders. The standard provides a common framework for measuring and demonstrating responsible practice. ResponsibleGlass is committed to complying with all relevant anti-trust and competition laws and regulations.
Getting Involved
Why is it important to get involved now?
The standard is being built right now, and the organisations involved at this stage have the greatest influence over what it contains and how it works.
When will the Standard be ready?
A first draft will be available for public consultation in July 2026, with the aim of a final Standard by the end of 2027/early 2028.
