The Sustana COOL™ Index is a proprietary financial index comprising publicly traded companies that, based on Sustana’s analysis, contribute significantly to cooling efficiency and the infrastructure required to meet rapidly growing cooling demand. The index spans sectors including artificial intelligence, data centers, food and healthcare cold chains, energy, logistics, real estate, and transportation.

Sustana Cooling Partners uses the index to benchmark private cooling-technology companies and monitor the market valuation and financial performance of potential strategic partners and acquirers. Sustana’s investment thesis holds that private-company valuations are influenced by public companies capable of acquiring private innovators—as illustrated by Ecolab’s acquisition of CoolIT Systems. Such acquisitions enable global commercialization of technologies developed by private companies.
