Product carbon footprint accounting quantifies the greenhouse gas emissions associated with a product's production, transportation, use, and disposal

What is product carbon footprint accounting?

Product carbon footprint accounting quantifies the greenhouse gas emissions associated with a product’s production, transportation, use, and disposal.
With the development of big data and the update of the global environmental outlook, product carbon footprint review has become a powerful proof, which can provide effective information and help enterprises to optimize their product manufacturing supply chain.

1. What is the carbon footprint of a product?

The carbon footprint of a product refers to the assessment of the greenhouse gas emissions generated in the whole life cycle of a product or service, from the exploitation, manufacturing, transportation and distribution of raw materials, use to the final disposal or recycling of raw materials, “cradle to grave”.

2. International standard of product carbon footprint accounting

PAS 2050

This specification was the first carbon footprint accounting of products proposed in 2008.

GHG Protocol

Based on PAS2050, this standard adds supplementary clauses and requirements to strengthen the concept elaboration.

ISO 14067

This standard is the calculation and identification of the carbon footprint. It is based on the ISO14040/14044 life cycle assessment framework and is prepared according to the PAS2050 and GHG Protocol standards. It has a strong universality and greatly improves the global influence of product carbon footprint accounting after its introduction.

3. Product carbon footprint accounting process

The processes are divided into three stages: the start-up stage, the carbon footprint calculation of the product and the subsequent certification. ​The first stage requires setting goals, selecting products, and engaging upstream and downstream suppliers. The second phase maps the process, checks boundaries and data collection to calculate the carbon footprint, and checks for uncertainty. The third phase of certification results in carbon footprint and emission reduction reporting.
