What is PAS 2050?

What is PAS 2050?

01 January 1970 by Roy Bidder

PAS (Publicly Available Specification) 2050 is a specification for assessing product life cycle Greenhouse Gas (GHG) emissions, prepared by British Standards Institution (BSI) and co-sponsored by the Carbon Trust and the Department for Environment, Food and Rural Affairs (Defra).

The original PAS 2050 standard, published in 2008, was the first of its kind. PAS 2050:2008 was written to create a reliable way of assessing the GHG emissions associated with the full life cycle of goods and services, from sourcing raw materials, through manufacture and distribution, to use and disposal. 

The new revised standard builds on its original methodology, while taking into account advances in knowledge and understanding in the field as well as the experiences gained through the use of PAS 2050:2008. According to the BSI, it also clarifies any ambiguities and is more in line with other international footprinting methods, particularly the GHG Protocol Product Life Cycle Accounting and Reporting Standard (WRI/WBCSD).

The assessment method has been tested by companies across a diverse range of product types, covering a wide range of sectors including:

  • Goods and services
  • Manufacturers, retailers and traders
  • Business-to-business (B2B) and business-to-consumer (B2C)
  • UK and international supply chains

PAS 2050 is intended to benefit organizations, businesses and other stakeholders by providing a clear and consistent method for the assessment of the life cycle GHG emissions associated with goods and services.

Benefits for companies include:

  • Internal assessment of product life cycle GHG emissions
  • Evaluation of alternative product configurations, operational and sourcing options, etc. on the basis of their impact on product GHG emissions
  • A benchmark for measuring and communicating emission reductions
  • Support for comparison of product GHG emissions using a common, recognised and standardised approach
  • Support for corporate responsibility

Benefits for consumers include:

  • Confidence that the life cycle GHG emissions being reported for products are based on a standardised, robust method
  • Greater understanding of how their purchasing decisions impact GHG emissions
