Product Carbon Footprint Guideline by TfS

Gold standard for calculating PCFs in the chemical industry

Committed to making chemical supply chains more sustainable, TfS members and suppliers also share the responsibility to reduce greenhouse gas emissions in the chemical industry.

Scope 3 (upstream) greenhouse gas (GHG) emissions constitute a major share of a chemical company’s emissions. Calculating the carbon footprint of products provides the best product-level information for identification, tracking and reducing scope 3 GHG emissions in the industry.

Taking the lead for the chemical industry, in September TfS launched the Product Carbon Footprint Guideline for calculation for chemical materials which will enable suppliers and corporations to produce and later on share high-quality carbon footprint data.

November 2022 update: Launch of a more robust version of the PCF Guideline covering also Corporate Accounting

On November 8, TfS launched an even more robust version of the PCF Guideline covering also Corporate Accounting. The full open-source PCF Guideline allows suppliers and companies to calculate PCFs and Corporate Scope 3 Category 1 (Scope 3.1 – purchased goods and services) GHG emissions. The updated Guideline will be a vital instrument for working on real and meaningful emission reductions to help decarbonise the entire industry together.

PCF Guideline now available in different languages

You can now view and download the PCF Guideline including Corporate Accounting on this website also in Chinese, Japanese and Spanish (see section below).

What will the future hold?

At TfS we are preparing an IT solution, i.e.: a platform that will enable corporations and suppliers to share upstream product carbon footprints. This should make it easier for businesses to conduct cross-industry comparisons and compile and manage their emissions across all three scopes.

The PCF Guideline is available in different languages

On 9 November 2022, WBCSD and Together for Sustainability hosted a virtual panel discussion with three major chemical companies – BASF, Merck, Mitsibushi Chemical – that have begun using the PCF Guideline. During this interactive event, cross-sector sustainability leaders and chemical companies shared their experience with the PCF Guideline, including:

• What it is
• How suppliers and corporations can use it
• How it can be rolled out in your organisation
• Above all, why it matters.

The recording of the event is now available!
