Product Carbon Footprint

How much greenhouse gas emissions are associated with a product along its life cycle? This question has become increasingly important over the past years and a Product Carbon Footprint (PCF) can help to find answers.

The PCF sums up the total greenhouse gas emissions generated by a product over the different stages of its life cycle. For example, a cradle-to-gate (partial) PCF considers all the processes from extraction of resources through manufacturing of precursors and the making of the final product itself up to the point where it leaves the company gate. A cradle-to-grave PCF covers the complete life cycle of the product, including the emissions from the use phase and end-of-life of the product.

While BASF is continuously working to achieve net zero CO2 emissions by 2050, more and more customers are making environmentally conscious purchasing decisions. Therefore, BASF has developed a digital application to calculate the cradle-to-gate PCFs for its 45,000 sales products. By the end of 2021, BASF will be able to provide PCFs for its global portfolio. Customers thus will receive valuable information about the extent to which BASF materials contribute to the carbon footprint of their business activities and their own final products.

BASF's PCF calculation is based on GHG emissions from its own plants and high-quality average data for purchased raw materials as well as purchased energy.


Options for reducing PCFs

PCFs provide our customers with valuable information on levers for avoiding greenhouse gas emissions. Already today we offer them added value through the use of alternative raw materials. In this way, we help our customers reduce the carbon footprint of their products.

One example is BASF's biomass balance approach, in which fossil resources are replaced by renewable raw materials from organic waste and vegetable oils in the production Verbund and mathematically allocated to the sales product. Another example of the application of the mass balance approach is the ChemCyclingTM project. Since 2020, BASF offered its customers the first commercial quantities of products that are manufactured using chemically recycled plastic waste at the start of production. The BASF sales products from both approaches have the same properties as products based on purely fossil raw materials – but with a lower carbon footprint.

Promotion of international standards and rules

BASF’s PCFs are calculated following general standards for life cycle assessment (ISO 14044) and carbon footprints of products (ISO 14067), as well as the Greenhouse Gas Protocol Product Standard.

These standards do not, however, include concrete specifications as to how exactly the PCF is to be determined for individual products. In the absence of such rules, PCFs of the same products from different companies cannot yet be fully compared. In order to create a level playing field, BASF is committed to the introduction of product-specific guidelines for the calculation of PCFs in the chemical industry to create an industry-wide level playing field and comparability of products. 

How to get a more holistic sustainability assessment

PCFs create transparency about greenhouse gas emissions associated with our products. At the same time, they are only one piece of a bigger sustainability picture. Comprehensive sustainability assessments of products include environmental, economic and social criteria. If customers want to get a more holistic picture, we recommend multi-criteria assessment tools like our Eco-Efficiency Analysis.
