BSI PAS 2060
The British Standards Institution announced the development of the PAS 2060 Standard for Carbon Neutrality in October 2009  with the objective of increasing transparency of carbon neutrality claims by providing a common definition and recognized method of achieving carbon neutral status.
The steering group was made up of a number of public and private organisations and associations, including the Association of British Certification Bodies, Aviva, BREEAM (BRE Environmental Assessment Method), Carbon Clear, The Carbon Neutral Company, EcoAct, The Carbon Trust, The Co-operative Group, Department of Energy and Climate Change, Eurostar, Future Conversations (Concrete Centre), Good Energy, Institute of Environmental Management and Assessment, Marks and Spencer, Oxford Brookes University and UPM-Kymmene.
PAS 2060 Specification for the demonstration of carbon neutrality was launched in June 2010.
Compliance with PAS 2060
The specification defines a consistent set of measures and requirements for entities (e.g. organisations, governments, communities, families, individuals) to demonstrate carbon neutrality for a product, service, organisation, community, event or building.
The carbon footprint measurements should include 100% of Scope 1 and Scope 2 emissions, plus all Scope 3 emissions that contribute more than 1% of the total footprint.
The entity must develop a Carbon Management Plan which contains a public commitment to carbon neutrality and outlines the following major aspects of the reduction strategy: a time scale, specific targets for reductions, the planned means of achieving reductions and how residual emissions will be offset.
• Genuinely additional (i.e. reductions that would not have happened anyway)
• Verified by an independent third party to ensure that emission reductions are permanent, avoid leakage (so that emissions are not increased in another area as a result of the project reductions) and are not double counted
• Retired after a maximum of 12 months to a credible registry.
Documentation and verification
PAS 2060 requires a standard-compliant declaration of achievement of neutrality through a set of Qualifying Explanatory Statements and public disclosure of all the documentation that supports the carbon neutrality claim.
The standard stipulates three types of validation of the achievement of neutrality: self validation, other party validation and third party independent validation. Other party validation occurs when the methodology and data has been audited and verified by an external organisation; third party independent validation occurs when it is verification is by an agent registered with UKAS.
