The International Carbon Reduction and Offset Alliance (ICROA) is a non-profit professional industry body hosting a membership of businesses that deliver carbon reduction and offset services. ICROA members operate globally and are managed by an independent secretariat housed within IETA. The primary aim of ICROA is to promote best practices in carbon management and offsetting to support voluntary climate mitigation efforts. ICROA keeps abreast of the latest developments within carbon management and the carbon markets to ensure its members adhere to the best possible practices in the industry. 

ICROA provides consumer protection for parties wishing to voluntarily manage and offset their carbon emissions by ensuring its member companies follow and publically report against the ICROA Code of Best Practice, which provides specific requirements for the manner in which ICROA members provide their carbon footprinting, greenhouse gas reduction advice and offset services. ICROA members are 3rd party audited to assure the quality of their services.

ICROA also works with Governments and other key stakeholders to:

Support fast, global emissions reductions through the promotion a responsible “reduce and offset” approach to carbon management by businesses and individuals. Promote credibility and high standards across the voluntary carbon market, through widespread adherence to and promotion of the ICROA Code of Best Practice. Provide a credible, influential and uniform voice on carbon reduction strategies, products and services and raise the profile of the voluntary carbon market. Enable bold carbon management strategies to be integrated profitably into business. Commit to shared learning, transparency and continuous improvement. Engage with Governments and other key stakeholders on voluntary carbon market issues to help ensure that best practice becomes the norm in the voluntary carbon market.

Quality Assurance for Carbon Management and Offset Providers: 

More and more organisations, businesses and individuals are aware of the impact they have on climate change and understand they have to act and reduce global carbon emissions. Carbon offsetting can play a part in a coordinated strategy to reduce your impact on the environment and in many cases provide support for sustainable projects and communities in developing countries. Organisations that participate in offsetting as part of a broader carbon management strategy allow for deep cuts in GHG emissions, thus reducing their environmental impact and enhancing their CSR contributions.

Developing a robust and credible offset-inclusive carbon management plan requires knowing where to find the highest quality carbon management and offsetting services. This is where the International Carbon Reduction and Offset Alliance (ICROA) guides and advises.
