The UK Government's Quality Assurance Scheme for Carbon Offsetting

The Quality Assurance Scheme for Carbon Offsetting (QAS) is a Government-led initiative aimed at increasing consumers’ understanding of the role of offsetting in tackling climate change and helping them to make informed purchases of good-quality offsets.


The Scheme’s Quality Mark can be used for offsets where it has been shown that they meet the specifications laid out in the Scheme's requirements and procedures document  and have been assessed by the Scheme's Approval Body - AEA Group plc.

In turn, individuals and businesses wishing to purchase offsets can use the Quality Mark to identify those offsets that meet key quality criteria and that provide the assurance that emissions are properly offset tonne-for-tonne. 

Approved offsets that have met the Scheme's requirements are listed here.


Background and purpose

The Government recognises the role that offsetting plays as part of a wider carbon management strategy. First of all, companies and individuals should take steps to measure and reduce their emissions where possible. Then, they should consider offsetting their remaining, unavoidable emissions. The Government helps people to easily identify quality offsets through the QAS. This falls within DECC's wider work on the ACT ON CO2 campaign. The Government's guidance on carbon neutrality and on how to measure and report greenhouse gas emissions complement the Scheme.

The main purpose of the QAS is to provide a straightforward route for those wishing to offset their emissions to identify quality offsets. By vouching for the quality of the offsets, the Scheme helps clear up the principle uncertainties involved in offsetting. In this way, it is hoped that the Scheme will address public confusion and mistrust of carbon offsetting. It is also hoped that the Scheme will help spread high quality standards and better information for customers across the carbon offsetting market.
