Our take
The market for carbon offset and RECs is growing fast, with firms and businesses looking to trade in order to meet sustainability requirements and ESG goals. With the market currently fractured and somewhat murky, however, a wave of startups are emerging to establish a dominant exchange that’s both centralized and transparent. Xpansiv is one of them - and it’s gotten a strong headstart on the competition.
Xpansiv allows companies to trade environmental commodities including offsets, RECs, and differentiated fuels. The platform offers a range of marketplaces, alongside signal data, portfolio management capabilities, and global registries.
So it’s a comprehensive combination of exchanges, analytics, and tools. Its edge, however, comes from its extensive backing. It’s struck a long term and hefty financing arrangement with Blackstone, the world’s largest private equity firm, and among its equity investors are BP, British Oil, Goldman Sachs and the Bank of America. This in total recently gave it a pre-IPO evaluation of over $1B.
With this top-tier industry involvement, Xpansiv looks set to net some major players. This will help Xpansiv establish itself as a leader in the emerging environmental and commodities exchange market.
