Presidential candidate Joe Biden says that candidates campaigning to eliminate carbon emissions by 2030 do not understand climate change science.
"Anybody who tells you they can eliminate carbon in the air by the year 2030 has no notion of the science," Biden said during an NPR interview released Monday. "Find me one scientist in the world. You guys, you guys know better than this."
NPR host Rachel Martin questioned whether Biden’s "Clean Energy Revolution and Environmental Justice" climate plan, which aims to eliminate carbon emissions by 2050, is progressive enough for Democratic voters.
"There are a lot of people who want a revolution on that front," Martin said. "It's not good enough to say it's a priority."
The former vice president pushed back, saying his plan is the most progressive within the Democratic presidential field.
Biden seemed to take aim at Rep. Alexandria Ocasio-Cortez (D., N.Y.) and Sen. Ed Markey’s (D., Mass.) Green New Deal proposal to reach zero-net carbon by 2030. Presidential candidate Sen. Bernie Sanders (I., Vt.) supports the Green New Deal and his own climate plan echoes its policies.
