  • 250,000 tonnes of carbon removal credits from the world’s largest mangrove restoration project sold at USD $27.80 per tonne
  • 30 per cent of volume bid at $35.00 per tonne and above, signalling the premium for Respira’s high-quality and unique ‘blue carbon’ credit type with new 2021 vintage
  • Powered by CIX’s platform which enables flexible, customisable auctions with high price transparency for opaque new carbon markets

Singapore and London, 4 November 2022 Climate Impact X (CIX), a global marketplace and exchange for quality environmental credits, and Respira International, an impact-driven carbon finance business, have completed a landmark auction for high-quality nature-based blue carbon credits. The auction successfully sold 250,000 tonnes of vintage 2021 carbon credits from the Delta Blue Carbon Project in Pakistan, the world’s largest mangrove restoration project, at USD $27.80 per tonne. This is $10.00 per tonne, or close to 40 per cent premium to current spot prices for major REDD+ nature-based solutions of the same credit vintage.

To facilitate price transparency in carbon markets, CIX is publishing the auction demand curve which showcases the range of bid prices submitted. 30 per cent of the bid volume was priced at $35.00 per tonne or more, 27 per cent above the auction reserve price ($27.50 per tonne), signalling the premium at which some buyers were willing to pay for high-quality and unique credit types.

Drawing many buyers from around the world, concentrated in Asia, Europe and the United States, the success of the auction demonstrates strong international demand for quality carbon credits given rising corporate net-zero commitments and in the run up to the 27th UN Climate Change Conference (COP 27). Despite a backdrop of high inflation and global macro uncertainty weighing on the whole carbon market, this represents a strong signal of support for premium credits of high integrity.

“CIX’s core priority is to build trust and transparency in the carbon markets to unlock liquidity, and one of the ways we seek to do this is through the discovery of clear demand and price signals. This auction offers reassurance to the market that demand for quality carbon credits remains robust. We are proud to work with partners like Respira to deliver landmark auctions, and together help to scale the next wave of impactful carbon sequestration solutions,” said Mikkel Larsen, CEO of CIX.

“Our long-term offtake agreements with project developers offer them revenue certainty whilst our profit sharing mechanism ensures they share the upside as demand and prices grow. We strive for higher prices for high-quality carbon credits in the market so as to channel private capital into these much-needed climate solutions, and are delighted to see such a strong demand signal. CIX’s focus on telling the suppliers’ story and showcasing the good work of project developers makes them an ideal partner to catalyse finance for these solutions,” said Ana Haurie, Co-founder and CEO of Respira.

Mangroves are some of the most effective natural carbon sinks on earth, with the ability to store up to five times more carbon than upland tropical forests.[i] The Delta Blue Carbon Project is protecting and restoring 350,000 hectares of tidal river channels and creeks, low-lying sandy islands, mangrove forests and inter-tidal areas along the southeast coast of Sindh in Pakistan. Over its lifetime, the project is expected to sequester around 142 million tonnes of carbon dioxide. It will also drive broader biodiversity and socio-economic impacts, which includes benefiting more than 42,000 people in local communities.

“I am delighted that all our hard work to establish the world’s largest blue carbon project is paying off.  The sale of the first delivered credits from the Delta Blue Carbon-1 project will secure the project’s long-term future and will allow my team to significantly scale up activities and further deliver on our plans. The funds will be channelled directly into on-the-ground activities as we strive to deliver environmental and climate benefits at scale – as well as improve the well-being and livelihoods of our local communities. Projects such as Delta Blue Carbon-1 require large-scale financing. Private sector investment through the carbon market is unlocking this new frontier in conservation,” said Nadeem Khan, Founder of Indus Delta Capital, project developer of the Delta Blue Carbon Project.
