Life cycle assessments

Life Cycle Assessments (LCA) are a method to determine the carbon footprint and environmental impact of products during their lifetime. We calculate LCAs so that we have a greater understanding of our carbon absorptions and emissions that results from the manufacture of our products. This helps is to identify where we offer intrinsic or in-use sustainability benefits and where we should focus on improvements. The results of our calculations can be used by our customers in their own scope 3 carbon emission calculations and we are happy to share this data with customers where possible.

The first ever LCA was conducted by Coca Cola in 1969 when they wanted to understand more about the environmental footprint of their products. The method used by Coca Cola is considered to be the foundation of the methodology used by many companies today. The growing pressure to reduce our carbon footprint makes product LCA more relevant than ever.

LCA - What do we measure?

We have implemented an LCA methodology to confirm the carbon footprint of our products. This is done using SimaPro software and follows technical specification ISO 14067. Our calculations are independently verified by external sustainability consultants to ensure total reliability and transparency of data.

Cradle to gate LCA benefits

Cradle to Gate calculations

Our calculations are Cradle to Gate, meaning that they take into account the raw materials and their processing, transport, production and packing of the product until the point it leaves our factory gates. Through our ambitions to be Climate, Land and People Positive we are committed to optimising the cradle to gate LCA process and collaborating within the value chain to contribute to the overall product lifespan carbon footprint.

A low to negative carbon footprint

Over 80% of our global Smart Materials product portfolio offers a low to negative carbon footprint whilst also meeting your product performance requirements. Our polymer additives, bio-based building blocks and ECO-surfactants are largely based on bio-based raw materials with a negative carbon footprint. That is the Cradle to Gate footprint, before even considering the in-use benefits when using our raw materials in your application, such as reduced energy consumption or an extended product lifetime.

The LCA results we have calculated play an important role, not only for our environmental impact assessments but also for those of our customers. We use these results to help assess the carbon footprint of our operations and to understand where we are with respect to our commitment to be climate positive by 2050. Our customers can also benefit from our low and negative carbon footprint products by incorporating our data in their own scope 3 emissions calculations, thereby saving on their CO2 emissions.

Bio-based versus fossil fuel-based products

We are committed to continuously improving the LCAs of our products. Furthering our sustainable sourcing practices, product development and innovation, and improving our processing are all critical elements that we are working on to achieve this.
