Assessing the lifecycle greenhouse gas emissions of goods and services
The PAS 2050 (Publicly Available Specification 2050) standard was published in 2008 as the result of collaboration by BSI British Standards, the Carbon Trust and Defra. It provides companies with the tools to analyse a product’s life cycle and assess embedded greenhouse gas emissions, from sourcing raw materials through packaging and distribution to consumer use and disposal impacts. It was anticipated that this could be a first step towards an internationally agreed standard for measuring greenhouse gas emissions.
