PAS 2060 Carbon Neutrality

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.[4]

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.
