Humanity has been trying to cut down on the estimated 40bn metric tons of carbon dioxide produced each year for decades. Some countries have imposed carbon taxes. Many businesses are looking at using alternatives to fossil fuels to make their products. For example, Coca-Cola invested millions of dollars in creating its PlantBottle, which gets its plastic from plants instead of petroleum, and saved 315,000 metric tons of CO2 between 2009 and 2015.
But both public and private efforts haven’t stopped global temperatures from rising. Now, a growing number of scientists and innovators are arguing that we need to look at new ways to prevent more manmade CO2 from escaping into the atmosphere.
Brent Constantz, CEO of building materials company Blue Planet, says he has a good solution: sequestering waste carbon dioxide into manmade limestone.
