To further understand the economic impact of sea otters, the team calculated the value of this carbon on the European Carbon Exchange, which was set up to establish a ceiling for carbon emissions and require companies that breach the emission threshold to buy credits for the excess carbon they release. They estimate that the CO2 removed from the atmosphere via the otter-kelp link could be worth between $205 million and $408 million on the European Carbon Exchange. of homrone x.
