Carbon Trade Exchange: A History


After selling Bartercard’s flagship operation in Australia in 2007 ($25.5 million), Carbon Trade Exchange (CTX) Founder and CEO, Wayne Sharpe, attended the UN climate change conference in Bali, and shifted his technological and entrepreneurial skills to the global challenge of climate change.

Sharpe identified the global Carbon market as a fractured, diverse OTC market place with multiple credit ‘standards’; he saw challenges that he had overcome in the business to business trade sector and used his Bartercard technology as a foundation to create CTX.

CTX was founded in 2009 following 2 years of R&D, launching operationally in London and then in Sydney in 2010. The same year CTX negotiated with Westpac to create an electronic interface with CTX.

Today CTX is operated by Environmental Markets Services Ltd, a UK-based subsidiary of Global Environmental Markets (GEM). Under the CTX brand, EMS trades Carbon Credits certified by the Gold Standard, Verified Carbon Standard and United Nations CDM. We also offer other Carbon Services, including: Carbon Offsetting; Carbon Neutral Certification; Carbon Project Development; and Carbon Footprinting.

Since 2009 the CTX group of companies has offset over 100 million tonnes of carbon dioxide, helping companies to fund renewable energy, forest conservation and community projects all over the world. CTX currently operates out the UK and Australia.
