Former Vice President Joe Biden’s climate plan appears to have used nearly identical language from other sources in at least five different passages.

Josh Nelson, co-director of environmentalist group CREDO Action, highlighted two instances where Biden’s campaign used the exact same language as left-wing nonprofits, without citations.

A subsequent review of Biden’s plan by The Daily Caller News Foundation identified three other examples of similarly phrased excerpts.

Biden: “Biden’s goal is to make CCUS a widely available, cost-effective, and rapidly scalable solution to reduce carbon emissions to meet mid-century climate goals.”

Carbon Capture Coalition: “Its goal is to make carbon capture, use and storage (CCUS) a widely available, cost-effective, and rapidly scalable solution to reduce carbon emissions to meet mid-century climate goals.”

Biden: “carbon capture, use, and storage (CCUS) is a rapidly growing technology that has the potential to create economic benefits for multiple industries while significantly reducing carbon dioxide emissions.”

Blue Green Alliance 2017 Senate letter: “Carbon capture and sequestration (CCS) is a rapidly growing technology that has potential to create economic benefits for multiple industries while significantly reducing carbon dioxide (CO2) emissions.”

Biden: “Aviation accounts for nearly 2% of global greenhouse gas emissions, and that portion is expected to increase. Unfortunately today, few low-carbon technologies or fuels have been developed to tackle this challenge.”

Vox: “Aviation accounts for about 2 percent of global greenhouse gas emissions, and that share is poised to grow… few low-carbon technologies or fuels have been developed so far.”

Biden: “The average American sewage pipe is 33 years old, with many pipes dating back 50 or even 100 years.”

American Rivers: “[T]he average American sewage pipe is 33 years old, with many pipes dating back 50 or even 100 years.”

Biden: “40% of the 567 federally recognized tribes in U.S. live in Alaska where the rapid pace of rising temperatures and melting sea ice and glaciers threaten the critical infrastructure and traditional livelihoods in the state.”

Climate.gov: “Of the 567 federally recognized tribes in the United States, 40 percent (229 tribes) live in Alaska Native communities. The rapid pace of rising temperatures, melting sea ice and glaciers, and thawing permafrost in Alaska is having a significant negative impact on critical infrastructure and traditional livelihoods in the state.”

Biden’s first campaign for president in 1988 was derailed after he was caught plagiarizing on multiple occasions. (RELATED: Artist Featured In Joe Biden’s ‘America’ Ad Actually From Denmark)

The Biden campaign did not immediately return TheDCNF’s request for comment.

After this article was published, the Biden campaign told Business Insider that the missing citations were “inadvertently” excluded.

“Several citations were inadvertently left out of the final version of the 22-page document. As soon as we were made aware of it, we updated to include the proper citations,” the campaign told BI.
