Climate change

A decarbonated home

Faced with the climate challenge, Saint-Gobain, which is committed to achieving net zero carbon emissions by 2050, aims to foster the emergence of a low-carbon economy in all the countries where it operates. In concrete terms, the objective is to help customers reduce their CO₂ emissions through the use of the Group’s products and solutions, while also reducing the carbon footprint of its own production. We are working to decarbonize both construction and industry by minimizing our footprint and maximizing our contribution.

Strategy

An Ambition Built on a Dual Contribution

Buildings and construction account for nearly 40% of global CO₂ emissions. To support the transition to a low-carbon economy, Saint-Gobain acts across its entire value chain by reducing the carbon footprint of its operations and developing solutions that help customers reduce emissions and adapt to climate change, with the ambition of reaching net zero carbon by 2050.

Since September 2019, Saint-Gobain has supported the United Nations Global Compact’s Business Ambition for 1.5°C and is committed to limiting global temperature rise to 1.5°C above pre-industrial levels. Its 2030 emissions reduction targets have been validated by the Science Based Targets initiative (SBTi) and are aligned with the Paris Agreement.

Saint-Gobain’s climate strategy is structured around three major pillars: a carbon roadmap for operations (Scope 1, 2 and 3), an adaptation plan addressing physical and transition climate risks, and a portfolio of sustainable solutions that support the decarbonization of markets.

Carbon Roadmap

Ambitious Interim Targets Through 2050

The success of the net zero ambition relies on interim targets for 2030 and 2035, before achieving full carbon neutrality by 2050. These targets are expressed in absolute emissions, not emission intensity.

2030 TARGET · SCOPE 1 & 2

−33%

Reduction in absolute direct and indirect emissions compared with 2017.

2030 TARGET · SCOPE 3

-16%

Reduction in upstream and downstream value-chain emissions compared with 2017.

2035 TARGET · SCOPE 1 & 2

−40% to −45%

New target under the "Lead & Grow" strategic plan.

2050 HORIZON

Net Zero

Net zero emissions across Scope 1, 2 and 3.

Four Decarbonization Levers to Achieve Our Scope 1 & 2 Targets

The 2030 roadmap is based on four key levers to reduce direct and indirect emissions:

Product optimization and eco-design: lightweight products, reduced packaging and increased incorporation of recycled materials.
Industrial excellence and energy efficiency: process improvement, deployment of digital tools and energy audits.
Innovation and new technologies: low-carbon glass, hydrogen.
Procurement of decarbonized energy: transition to renewable electricity and biogas.

Internal Carbon Pricing: A Strategic Steering Tool

Since 2016, Saint-Gobain has implemented two internal carbon price levels, regularly updated to reflect market developments:

€100/tCO₂ for industrial and energy-related investments.
€200/tCO₂ for breakthrough R&D projects.

This internal carbon price guides investment decisions, informs capital allocation and strengthens low-carbon innovation projects. Emissions reduction is also integrated into both the short- and long-term remuneration criteria for Group executives.

Acting Across the Entire Value Chain

Saint-Gobain’s Scope 3 emissions are concentrated in three main areas: raw materials and energy purchases (Categories 1 and 3), transportation and logistics (Categories 4 and 9), and purchases related to distribution activities (Category 1). The action plan focuses on three areas:

Product reformulation: replacing the most carbon-intensive raw materials with recycled inputs or low-carbon alternatives.
Innovation and logistics performance: multimodal optimization of the supply chain.
Procurement decarbonization: collection of verified LCAs, integration of climate maturity criteria into supplier assessments and deployment of joint action plans.

Maximizing Our Contribution

Solutions for Decarbonizing Construction

Beyond reducing its own footprint, Saint-Gobain develops and markets solutions that enable customers to significantly reduce their CO₂ emissions, particularly during the use phase of buildings.

~979 Mt

of CO₂ Emissions avoided
over the full lifetime of the solutions
(based on 2025 sales).

Saint-Gobain estimates that nearly 979 million tonnes of CO₂ emissions will be avoided through the solutions produced and sold in 2025, measured across their full life cycle. This assessment, independently verified by a third party, covers residential and non-residential buildings as well as technical insulation and piping activities.

Methodology aligned with the latest international recommendations (GHG Protocol, World Resources Institute) and regularly updated since 2015.

Driving the Construction Sector Transition

Saint-Gobain is a founding member of the Global Alliance for Buildings and Construction (GlobalABC) and actively contributes to the Buildings Breakthrough initiative. The Group participated in COP30 in Belém in November 2025, contributing to the organization of the first ministerial meeting dedicated to buildings and climate.

Saint-Gobain is also a partner of the global network of Green Building Councils (GBCs), a member of more than half of local GBC organizations worldwide, and participates in both the Energy Transitions Commission (ETC) and the World Business Council for Sustainable Development (WBCSD).

The 2025 Sustainable Construction Barometer, published by the Saint-Gobain Sustainable Construction Observatory, highlights significant global progress in the understanding of sustainable construction.

Just Transition

An Inclusive and Socially Responsible Decarbonization Pathway

The transition to sustainable construction cannot succeed without a strong social and inclusive dimension. Saint-Gobain explicitly integrates just transition considerations into its climate roadmap.

Tackling Energy Poverty

Building renovation programs that improve energy efficiency have a direct and positive impact on household energy bills, particularly for people experiencing financial hardship. The Build Change program, launched in 2022, identifies and promotes initiatives undertaken by countries in support of social housing. The Saint-Gobain Foundation supports projects that improve access to decent housing for vulnerable and excluded populations.

Creating Jobs in the Circular Economy

Achieving net zero objectives requires increasing the use of low-impact raw materials, particularly recycled materials. This involves developing new construction waste collection and recycling streams. In several countries, these emerging value chains create employment opportunities for disadvantaged and marginalized populations. In France, the social and solidarity economy plays an active role in glass and wood recycling. The Saint-Gobain Foundation supports integration and employment initiatives linked to the development of more circular ecosystems.

Addressing Housing Needs in Emerging Economies

Rapid urbanization and population growth are driving increasing demand for housing, particularly in emerging countries. Lightweight construction solutions provide an efficient and lower-impact response to these challenges. Saint-Gobain is committed to steering the construction sector toward a low-carbon pathway through its country platforms and local partnerships.

Adaptation Plan

Preparing for the Impacts of Climate Change

Saint-Gobain is committed to understanding and anticipating the impacts of climate change on its activities. Its assessment is based on three climate scenarios looking to 2050 (ranging from +1.5°C to +4.5°C above pre-industrial levels) and drawing on the latest IPCC science. These scenarios consider:

Acute physical risks: adaptation of sites to flood risks, seismic hazards and water stress.
Heat-related risks: deployment of prevention measures and adaptation of working conditions to address extreme weather events.
Transition risks: anticipation of regulatory developments and support for the pathway to net zero emissions by 2050.
Adaptation opportunities: development of solutions meeting growing demand for renovation, energy efficiency and building resilience.
