Global Consultation Opens on First-Ever Sustainability Standard for Glass Industry

ResponsibleGlass has unveiled the initial draft of its International Standard for Glassmaking, a pioneering effort to establish the world’s first global sustainability certification and labelling system for the glass sector. The draft is now subject to a 60-day public consultation, inviting input from businesses, suppliers, policymakers, NGOs, and other stakeholders to refine the framework.

Formed in 2025 as a not-for-profit organisation, ResponsibleGlass unites key players across the glass value chain, including manufacturers, raw material suppliers, recyclers, brands, sustainability experts, and civil society groups. Since its inception in December 2025, the organisation has expanded to include 23 Founding Members and Supporters, encompassing some of the largest glass producers and global companies from automotive, retail, construction, and luxury goods industries. Collectively, these members employ over 150,000 people and generate approximately $90 billion in annual revenue.

Among the founding members are Jaguar Land Rover, ARUP, Belron, Ciner Glass, Climate Group, DSS+, IRMA, NSG Group, Stara Glass, WE Soda, ARM, Cary Group, and ERM CVS. The initiative is led by Francis Sullivan, former Head of Sustainability at HSBC, and Alan Knight, former board member of ResponsibleSteel, which successfully developed internationally recognised sustainability standards for the steel industry over the past decade.

Glass is integral to modern life, featuring in buildings, vehicles, food packaging, solar panels, and advanced technologies. However, the industry is responsible for approximately 95 million tonnes of CO₂ emissions annually worldwide and has lacked a unified international sustainability framework, unlike sectors such as steel and forestry. ResponsibleGlass aims to fill this gap.

The draft standard proposes an independently verifiable framework covering the entire glass value chain—from raw material sourcing and energy use to production, product design, and recycling. Glassmakers seeking certification would be assessed on governance, responsible sourcing, environmental performance, worker welfare, community impact, and circularity.

The framework is organised around six core areas:

• Management systems: Ensuring companies have policies and reporting mechanisms to manage sustainability effectively.
• Responsible business practices: Covering legal compliance, anti-corruption, stakeholder engagement, transparency, and public sustainability reporting.
• Responsible sourcing: Requiring assessment of environmental and social impacts of raw materials, recycled content, and energy sources, promoting supply chain transparency.
• Environmental performance: Addressing greenhouse gas emissions, energy use, water stewardship, biodiversity, waste management, air emissions, and pollution, with mandatory measurement and disclosure.
• People and communities: Focusing on worker health and safety, labour and human rights, and community engagement.
• Circularity and sustainable product design: Encouraging increased recycled material use, improved recycling rates, and product designs that reduce environmental impacts throughout their lifecycle.

Certification would require independent audits to verify compliance with these criteria. The standard also introduces common rules for measuring and reporting sustainability metrics such as carbon emissions and recycled content, facilitating easier comparison across the industry and forming the basis for a certification and labelling system.

The draft standard follows six months of collaborative development involving ResponsibleGlass members, supporters, and stakeholders. Feedback from earlier preliminary proposals informed the current draft, which was shaped by working groups focused on responsible sourcing, greenhouse gas emissions, circularity, and downstream certification and claims. These groups provided technical input and tested definitions to ensure the framework addresses key sustainability challenges.

The consultation period is critical to ensure the final standard reflects the broader glass ecosystem’s views. Responses from businesses, customers, recyclers, policymakers, NGOs, and others will inform an updated version expected in early 2027.

Francis Sullivan, Chair of ResponsibleGlass, commented: “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. That’s 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.”

Matthew Wenban-Smith, Standards Lead, added: “Having worked on global standards for decades, from the early days of the FSC for forestry to the establishment of ResponsibleSteel, I have seen first-hand how multi-stakeholder certification can create value for sustainability performance across an industrial sector. With ResponsibleGlass, we are applying that same proven rigour to glass production.

“While driving down carbon emissions is a critical priority, true sustainability cannot be defined by a single metric. This standard deliberately covers the full ESG spectrum, addressing sustainability data transparency, circularity, resource management, and social impact.

“This draft is our starting point, and we now look to the technical expertise and diverse perspectives of the global glass community during this 60-day consultation to ensure the final standard is robust, practical, and highly impactful.”

David Cast, Environment & Climate Change Director at NSG Group, said: “We make glass in dozens of plants across multiple continents, using processes that have to work reliably at enormous scale – so when we think about a standard for responsible glassmaking, our first question is always: can this actually be implemented on the factory floor, everywhere we operate, not just in a handful of best-case sites?

“That’s the perspective we’ve tried to bring as a founding member of ResponsibleGlass — pushing for a Standard that’s ambitious, but also grounded in what’s technically and operationally achievable across a genuinely global industry. Our technical teams have been closely involved in the working groups shaping this draft, stress-testing definitions and criteria against the realities of running furnaces, managing emissions and adapting production lines.

“Seeing Draft v1.0 published is the result of a huge amount of that kind of detailed, practical work, and we’d encourage manufacturers everywhere — large and small — to look closely at it and respond during the consultation.”

Alan Knight, Chief Sustainability Officer at WE Soda, stated: “Every piece of glass is only as sustainable as the raw materials that go into it. We are the world’s largest producer of soda ash, a key component of glass making, and we’ve always believed that responsible sourcing upstream matters just as much as what happens downstream.

“Soda ash is a critical raw material for glass, and so its sustainability credentials must be considered. Natural soda ash has a significantly lower carbon and water footprint than the synthetic alternatives. A global standard is a credible way for those credentials to be valued by the whole supply chain, right down to the end user. We were glad to be a founding member of ResponsibleGlass, and this first draft is a significant milestone for the glass industry.”
