Sustainability is no longer a future ambition, it’s a business imperative. At Lubrizol, we are committed to delivering high-performance solutions while actively reducing our environmental footprint. A key focus of this journey is the decarbonization of our Carbopol® and Pemulen™ polymers powder production, manufactured at our strategic sites in Kallo, Belgium and Calvert City, USA.

Through targeted initiatives, industry partnerships, and continuous data optimization, we are making measurable progress toward lowering Product Carbon Footprint (PCF)* and supporting our customers in meeting their Scope 3 emissions reduction goals.

Transforming Steam Usage in Kallo, Belgium

Our Kallo site is a vital production hub for Carbopol® and Pemulen™ polymers powder, and a focal point for impactful decarbonization efforts.

One of the most significant levers for emissions reduction at this site is steam consumption. To address this, we implemented a major shift on how steam is sourced and generated.

Key Highlights:

Transition to Waste-to-Energy Steam:
Historically, steam supplied to Kallo was generated using conventional natural gas boilers. In 2025, our supplier fully transitioned to the ECLUSE** waste-to-energy network, which captures residual heat from waste incineration and converts it into usable steam.
Major Shift in Energy Mix:
Today, more than 90% of Kallo’s steam demand is met through the ECLUSE network, significantly reducing reliance on fossil fuels.
Substantial Emissions Reduction:
This transition is expected to reduce annual CO₂e emissions by approximately 7,000 metric tons, while also contributing to lower local NOₓ emissions.
Direct Impact on Product Carbon Footprint:
These improvements translate into a 20% reduction in PCF for Carbopol® and Pemulen™ polymers powder produced at the Kallo facility.

Enhancing Data Accuracy and Supplier Collaboration in Calvert City, USA

At our Calvert City site, decarbonization efforts have begun with a strong foundation: improving the accuracy and quality of emissions data. This critical step ensures we can identify the most effective opportunities for reduction.

Key Progress Areas:

Updated Electricity Emission Factors:
By switching to more accurate emission factors for electricity usage, we achieved a 3.6% reduction in Carbopol® polymer PCF.
Primary Data Integration from Suppliers:
Collaborating with key feedstock suppliers to access primary emissions data has unlocked an additional 3% reduction in Carbopol® polymer PCF.
Pipeline of Future Initiatives:
Looking ahead, initiatives such as transitioning to Renewable Energy Certificates (RECs) and expanding primary data sourcing across more suppliers are expected to drive further PCF reductions.

Delivering Measurable Impact, Now and in the Future

The combined impact of these initiatives across both Kallo and Calvert City is substantial. By 2026, customers can expect significant reductions in PCF for Carbopol® and Pemulen™ polymers powder, with updated PCF data available by August.

Our journey doesn’t stop here. Additional programs are already underway, with new reductions anticipated in 2027 as we continue to optimize energy sourcing, manufacturing processes, and supply chain transparency.

Building a More Sustainable Future Together

At Lubrizol, decarbonization is not just about operating responsibly, it’s about creating value for our customers. By lowering the environmental impact of our products, we empower our partners to achieve Scope 3 emissions reduction targets, enhance the sustainability credentials of their formulations, and align with evolving regulatory and consumer expectations.

Lubrizol remains fully engaged in the decarbonization of its major manufacturing facilities, strengthening the sustainability profile of our polymer portfolio while maintaining the high performance and quality our customers expect. Together, we are building a future where innovation and sustainability go hand in hand.
