What is carbon footprint certification? What is the carbon footprint certification process?

Regarding standards for carbon footprint verification, we have compiled a report outlining the documentation enterprises need to prepare in advance—feel free to contact us to obtain it. Let me now elaborate further. Product carbon footprint certification (verification) follows three major standards: 1. PAS 2050: The earliest standard (launched in 2008), functioning like a foundational template. It divides a product’s life cycle into two pathways: “cradle-to-gate” for business-to-business (B2B) products (covering emissions only up to factory gate), and “cradle-to-grave” for business-to-consumer (B2C) products (accounting for emissions through end-of-life disposal). Many current standards still adopt this conceptual framework. 2. GHG Protocol: This protocol classifies greenhouse gas emissions into three “scopes”: Scope 1 (direct emissions from on-site combustion or industrial processes), Scope 2 (indirect emissions from purchased electricity, steam, heating, or cooling), and Scope 3—the most critical and complex category—encompassing all other indirect emissions across the upstream and downstream value chain. It is especially well-suited for managing emissions across an entire supply chain. 3. ISO 14067: Considered the “culmination” of the first two standards, ISO 14067 is today’s internationally recognized gold standard. It unifies quantification methodologies and reporting requirements, placing strong emphasis on data transparency and global mutual recognition. Certificates issued under this standard are widely accepted in international markets. ICAS Intertek’s certification services are fundamentally built upon ISO 14067. Certification Process Demystified: Not So Mysterious—But Full of Nuance The process is actually quite straightforward; here’s a breakdown of the key steps: 1. Initiation & Preparation: Enterprises must first decide which product(s) or product category(ies) they wish to certify, then sign a contract with a qualified certification body like ours. Internally, they form a dedicated team and begin collecting and organizing relevant data—a step that often consumes the most time and is prone to errors. Raw material data comes from suppliers; production energy consumption is drawn from electricity and gas meters; logistics and transportation records are sourced from internal logs. 2. Calculation & Modeling: Our expert team conducts on-site visits—or provides remote guidance—to quantify carbon footprint values using professional models and methodology aligned with the selected standard (e.g., ISO 14067). This stage involves iterative communication and validation to ensure no data gaps or calculation errors exist. 3. Independent Audit: The pivotal phase—akin to an “exam.” An independent audit team visits the enterprise’s site to conduct forensic-level verification: Are the data authentic? Were collection methods appropriate? Is the calculation process compliant? Are any emissions being concealed? Any nonconformities identified (e.g., missing source documentation for a particular data point) require corrective action. 4. Certification & Ongoing Compliance: Upon successful audit, congratulations! We issue a product carbon footprint certificate bearing internationally recognized accreditation marks. However, certification is not the finish line. Certificates typically carry validity periods (e.g., three years), during which surveillance audits may occur—and enterprises must continuously monitor and update their data.

Yield exceeds 90%, carbon footprint plummets! Five industry giants bet big on PMMA chemical recycling—regenerated acrylic market surges.

Röhm’s published data is highly impressive: depolymerization yield exceeds 90%. Sumitomo Chemical’s test results are even more direct: chemically recycled PMMA exhibits performance virtually identical to virgin material. This is precisely what the industry giants truly value—not environmental sentimentality, but tangible commercial value. The Giant Sprint: A Race Defined by Timing Globally, only five players have reached the “commercial-scale production” finish line in the PMMA chemical recycling arena: Röhm In March 2026, Röhm Group announced the industrial deployment of its PMMA chemical recycling technology at its Worms plant in Germany—marking the formal establishment of Europe’s closed-loop PMMA circular system. Leveraging its proprietary depolymerization–in-line purification technology, Röhm converts waste PMMA into electronic-grade recycled methyl methacrylate (MMA) at over 90% yield, seamlessly integrating the output into existing MMA production lines. This reduces carbon footprint by over 90%. The technology features high integration, ultra-high purity, and low-cost scalability. In collaboration with the European PMMA Recycling Alliance, Röhm has established an annual processing capacity of 5,000 tons of recycled PMMA. Starting in 2027, recycled MMA will be fully deployed across Röhm’s proTerra eco-series—used in automotive tail lights, medical devices, and architectural panels. As the lead organizer of the European PMMA Recycling Alliance, Röhm sets a benchmark for regional chemical circular economy via full-value-chain integration. Sumitomo Chemical In February 2026, Sumitomo Chemical, in partnership with U.S.-based Lummus Technology, commercialized its PMMA chemical recycling technology (PMMA-CR). This collaboration began in May 2024, combining Sumitomo’s materials innovation expertise with Lummus’ process engineering strengths. The technology efficiently converts PMMA waste into high-purity MMA monomer, with regenerated product quality matching fossil-based feedstock. Its full lifecycle carbon emissions are reduced by approximately 50%. Validated at Sumitomo’s pilot plant in Japan, the technology delivers high yield, high purity, and ready scalability. Its modular design supports capacities ranging from 10,000 to over 50,000 tons per year—ideal for high-value applications including automotive lighting, electronics, and medical devices. Lummus serves as the exclusive global technology licensor and EPC provider. This breakthrough effectively resolves PMMA waste disposal challenges and delivers a scalable solution for petrochemical circular economy and carbon neutrality.

Initial trials were conducted in collaboration with Agilyx at its Tigard, Oregon facility—successfully demonstrating technical feasibility. Subsequently, Mitsubishi expanded partnerships across multiple sectors, notably focusing on end-of-life vehicles, including collaborations with Tokyo Marine & Fire Insurance, ABT, Honda Motor, and Microwave Chemical. The company plans to officially launch its commercial-scale PMMA recycling plant in fiscal year 2025, targeting electronics and automotive customers across Japan and Asia. Figure source: Shunqi Network Chi Mei Corporation As Taiwan’s leading chemical enterprise, Chi Mei holds globally leading PMMA chemical recycling technology. In April 2022, it launched the world’s first optically grade light guide plate made from chemically recycled MMA. By Q3 2023, it achieved mass production of optical-grade recycled PMMA. In March 2024, it unveiled its ECOLOGUE eco-series MS resins, entering consumer electronics supply chains comprehensively. Utilizing its proprietary pyrolysis–distillation purification technology, Chi Mei transforms waste PMMA into high-purity recycled MMA—matching virgin material in performance and delivering ~40% overall carbon reduction. The technology excels in purity, low energy consumption, and suitability for optical-grade applications. With manufacturing bases in Tainan (Taiwan) and Zhenjiang (Jiangsu Province, China), Chi Mei achieves large-scale production. Its recycled materials are already applied in high-end optical components—including display light guide plates and backlight modules.
