Instead of sequestering or storing CO2 underground so it won’t be emitted, biofuel manufacturers are using it as a feedstock to grow algae. This most definitely a win-win situation. The algae is then used to create biofuel.
The cement industry is also using CO2 as a feedstock.
With carbon-capture industries like these gaining ground, it’s not hard to envision a future where CO2 is treated less as the enemy and more as an integral ingredient in the global economy. While a zero-carbon future is “hard to imagine,” Zenk said, “I think you’ll find [a] low-carbon [future.] We can win the war on climate if we think about it in those terms, at least in my lifetime.
