This PAS specifies requirements for the assessment
of the life cycle GHG emissions of goods and services
(collectively referred to as “products”) based on key
life cycle assessment techniques and principles. This
PAS is applicable to organizations assessing the GHG
emissions of products across their life cycle, and to
organizations assessing the cradle-to-gate GHG
emissions of products.
Requirements are specified for identifying the system
boundary, the sources of GHG emissions associated
with products that fall inside the system boundary,
the data requirements for carrying out the analysis,
and the calculation of the results.
This PAS addresses the single impact category of global
warming, and does not assess other potential social,
economic and environmental impacts arising from
the provision of products, such as non-greenhouse
gas emissions, acidification, eutrophication, toxicity,
biodiversity, labour standards or other social, economic
and environmental impacts that may be associated
with the life cycle of products. The life cycle GHG
emissions of products, calculated using this PAS, do
not provide an indicator of the overall environmental
impact of these products, such as may result from
other types of life cycle assessment.
This PAS does not include product category-specific
rules for goods and services; however, it is intended
that selected product category-specific rules for goods
and services, developed in accordance with BS ISO
14025, will be adopted where available, as specified
in this PAS.
It is one of the intentions of this PAS to allow for the
comparison of GHG emissions between products, and
to enable the communication of this information.
However, this PAS does not specify requirements for
communication.
