You might have heard the news today that the Obama Administration released its final version of a rule called the Clean Power Plan. Years in the making, this rule from the Environmental Protection Agency aims to reduce emissions from power plants – the biggest emitters of carbon pollution – by 32 percent from 2005 levels by 2030. We hear a lot about how carbon pollution causes our planet’s atmosphere to warm, and as a result, droughts, wildfires, and extreme weather events, are becoming more frequent, dangerous and costly to Americans and many others around the world. But what does carbon pollution mean for the ocean?
Today, Environmental Protection Agency (EPA) Administrator Gina McCarthy announced that the agency is proposing new rules to dramatically reduce carbon dioxide emissions from existing power plants. The new rules, which the EPA is calling their “Clean Power Plan,” would reduce carbon emission from existing power plants by 30 percent from 2005 levels by 2030, an amount equal to the pollution emitted by more than 150 million cars. But what does all of this mean for the ocean? Many people may not realize it, but by proposing the Clean Power Plan, the United States took a significant step towards addressing ocean acidification. Reducing carbon pollution from power plants means there will be less carbon pollution in the atmosphere. And less carbon pollution in the atmosphere means less carbon pollution that is absorbed by the ocean, turning it more acidic.
