QAS-Certified Carbon Offsets
Clear is on a mission - to make it easy for everyone to take action on climate change.
#JoinOurMission #QAS-Certified
Clear ranked in top 5% worldwide
Clear is proud not only to be a Certified B Corp since 2021 but also to have been selected as one of the Best for the World™ B Corps in the Environment category the following year!
To be #BestForTheWorld, B Corps must have scores in the top 5% globally for one or more of the five impact areas assessed towards the certification.
As all #BCorps are already businesses that meet high standards of verified social and environmental performance, public transparency, and legal accountability to balance profit and purpose, this is an important additional recognition.
You can find Clear’s BCorp listing here.

2 Our calculators are the most accurate available and are updated every year
The carbon emissions calculators on this site provide live AJAX updating and are based on the most up-to-date understanding of carbon dioxide emissions possible, continually updated to be the most accurate available and successfully audited by the Quality Assurance Standard every year since 2011. We include several sources of climate warming that most other online calculators miss out – such as getting fuel from the point of extraction to the point of access, and non-CO2 greenhouse gases. Our methodology document is here.
3 Our climate mitigation projects are the very highest grade
Like our calculators, the climate projects we use all meet the demanding specification of the Quality Assurance Standard. Clear.eco has been audited successfully every year since its inception in 2011.
4 Clear is efficient and trades ethically
Clear is extremely efficient, with carefully minimised overheads and all profits reinvested in the company. We provide a free carbon audit tool for any organisation in the world, updated every year with new emissions factors. We also provide a free hour of consultancy to help organisations started on their journey to net zero. Our sole aim is to tackle climate change. Our prices are competitive, and we can usually negotiate discount for large volume sales.
5 Our pricing is fair and affordable
Clear charges a flat fee per tonne of carbon emission achieved, which includes all the checks and balances that come with a Quality Assurance Standard audited product. You can check our current price per tCO2e by checking any of our carbon offset pages.
6 We listen to people!
Clear prides itself as a flexible, forward-thinking organisation. The ideas for several of our products came from people we work with.
How do climate contributions work?
1. MEASURE, REDUCE, CONTRIBUTE
Climate change is a challenge facing every one of us. Our responsibility starts with measuring our harmful emissions, or carbon footprint. There’s lots of advice available on how to reduce our footprint, but until the world decarbonises, there’s always some residual emissions left. That’s where climate contributions can help.
2. WHAT IS A CLIMATE CONTRIBUTION?
A good climate project mitigates harmful emissions by reducing carbon emissions somewhere else, for example replacing a coal-fire electricity plant with wind turbines. Unavoidable emissions are still harmful, but investing in projects which reduce emissions elsewhere helps gets finance to where its needed to allow the world to decarbonise.
3. HOW CAN I BE SURE ABOUT MY CLIMATE CONTRIBUTION?
Many climate companies fail to meet the stringent standards expected by businesses and consumers that are mandated by the Quality Assurance Standard.
4. CLEAR’S APPROACH
Clear is different. We only use the highest quality projects which meet the standards set by the Quality Assurance Standard. This ensures that every kilogram of carbon reduction you pay for is real and verifiable.
What is the Quality Assurance Standard?
The Quality Assurance Standard (QAS) has been benchmarking climate firms against the most rigorous quality standards in the world for voluntary climate contributions since 2011. The aim is to allow consumers and businesses to mitigate their carbon emissions with complete confidence. The QAS is the only climate contribution standard which is independently audited – this makes it independent from both carbon credit providers and the organisations which run the carbon credit verification programmes.
Clear is the only carbon offset provider to have achieved Quality Assurance Standard (QAS) Certification for all of its climate contribution products – this includes all our online products and our offline carbon audit tool for small business. Our base price is always displayed on our homepage, in tCO2e (tonnes of greenhouse gas reduction equivalent to CO2). Our most recent audit was 2025 and we are scheduled to be audited again in 2026.
The following are key criteria for compliance:
- Highest levels of accuracy available for online carbon calculators
- QAS-certified credits retired within six months of the end of each QAS audit period with double counting checks by an independent auditor
- Clear & transparent online pricing
- Must provide information on climate change, the role of climate contributions and how to reduce your carbon footprint
Our online carbon calculators and our free downloadable Carbon Audit Tool meet all these requirements and use the latest calculation factors updated every year. We also use total emissions of CO2, CH4 and N2O (in CO2e), rather than CO2 emissions only.
