AirCarbon Exchange wins “Best Carbon Exchange” in Environmental Finance’s 2021 Voluntary Carbon Market Rankings



AirCarbon Exchange (ACX) is extremely proud to have been recognised as the Best Carbon Exchange in Environmental Finance's prestigious Voluntary Carbon Market Rankings 2021 - the largest and most closely watched survey of the world's Voluntary Carbon market. ACX was launched in 2019 with a vision of bringing transparency, efficiency and liquidity to the voluntary carbon markets, and this award is an affirmation by industry participants worldwide of our innovation and the impact we have made.

“We have seen an exponential increase in interest in the Voluntary Carbon Markets from the private sector. Clients from around the world have been looking for the most efficient and transparent way to trade voluntary credits. We are proud to be the one they have chosen,” said Thomas McMahon, Co-Founder and CEO of ACX.


William Pazos, Co-Founder and Managing Director of ACX, added, “We are becoming a truly global exchange. Our existing presence in Abu Dhabi, covering the MENA region, is being followed by an active presence in the UK, Canada, Brazil, and soon South Africa. We will continue to push innovation.”


Transaction volumes on ACX have increased rapidly, with 2,101,175 tCO2e transacted in the last two months compared to 3,603,284 tCO2e in the first six months of 2021. With the increasing interest in the voluntary carbon markets as well as ACX’s expanding footprint, we fully expect this growth to continue.
