Regarding carbon footprint management, the Ministry of Ecology and Environment released the "Methods and Requirements for Quantifying the Carbon Footprint of Greenhouse Gas Products - Flat Glass (Draft for Public Comment)" on March 20, 2025, soliciting public opinions. This standard clarifies the scope of application, terminology definitions, and quantification methods for carbon footprint quantification of flat glass products, providing a detailed data collection list and default values ​​for carbon footprint factors. The standard requires that the carbon footprint calculation for flat glass products include all units involved in the raw material and energy acquisition stages and the raw glass production stage.

The release of the draft for comments is an important measure to implement the tasks outlined in the "Work Plan for Accelerating the Construction of a Dual Control System for Carbon Emissions" and the "Implementation Plan for Establishing a Carbon Footprint Management System," aiming to accelerate the development of carbon footprint accounting standards for key products and further improve the national ecological and environmental standards system.

5.1.2 EU and US Policy Trends

The EU continues to advance its ambitious Green New Deal in 2025, imposing stricter environmental requirements on the glass industry. Regarding the EU Emissions Trading System (EU ETS), the flat glass industry is not on the indirect emissions offset list, therefore no member state provides incentives for the industry to adopt electrification. This policy environment compels companies to achieve emission reduction targets through technological innovation.

The EU's Carbon Border Adjustment Mechanism (CBAM) also has a significant impact on the glass industry. From 2025, CBAM will only allow the use of the EU accounting method, with direct emissions calculated based on default values ​​not exceeding 20% ​​of the total product emissions. Glass Alliance Europe, in its contribution to the CBAM evidence collection, pointed out that indirect emissions from electricity use should be based on the manufacturer's verified actual electricity consumption multiplied by the verified CO2 intensity of the facility's electricity supply provided by the energy supplier.

In the United States, while federal-level uniform carbon policies are relatively limited, state and local governments, as well as businesses, are very active in emissions reduction efforts. O-I Glass's 100% biofuel trial at its Harlow factory in the UK is part of the UK government's "Net Zero Innovation Portfolio" program. This project demonstrates a model for companies to advance sustainability by participating in government-supported innovation projects in the absence of a unified federal policy.

The development of this standard will encourage companies to establish comprehensive carbon emission monitoring, reporting, and verification systems, promoting carbon reduction actions across the industry.

From an international perspective, the EU's carbon footprint management system is relatively mature. Glass Alliance Europe, in its position paper, emphasized the importance of accurately calculating indirect emissions, particularly those generated from electricity use, which should be based on actual consumption and emission factors provided by suppliers. This approach provides an important reference for the development of Chinese standards.

Corporate carbon footprint management practices are also deepening. Saint-Gobain, in its "Lead & Grow" strategy, has set clear carbon reduction targets, planning to achieve carbon neutrality by 2030, and supporting this goal through an investment of approximately €12 billion in innovation and sustainable development. AGC, through innovative initiatives such as the Volta project, is committed to significantly reducing CO2 emissions and improving energy efficiency in production.

The promotion of carbon footprint management also requires collaboration across the entire industry chain. From raw material procurement and manufacturing to product use and recycling, carbon emissions at each stage need accurate accounting and effective management. The success of LionGlass™ technology lies not only in the decarbonization of the production process but also in the lightweight design of its products, which reduces carbon emissions during transportation and use.

In the future, with the improvement of carbon footprint management standards and the development of the international carbon market, carbon footprint management in the glass industry will shift from voluntary action to mandatory requirements. Enterprises need to plan ahead and establish a comprehensive carbon management system through technological innovation, process optimization, and recycling.

Using various methods, carbon emission reductions can be achieved throughout the entire life cycle to adapt to increasingly stringent environmental requirements and market competition.
