For the past two years, the Chicago metro chapter of the Climate Reality Project has been urging the CTA to pursue electrification of its fixed route bus fleet more aggressively.
Even though the CTA has promised to operate a 100% zero-emission bus fleet by 2040, it continues to order new diesel buses. In 2021, CTA signed a contract for 600 new diesel buses, and these buses will continue to be delivered through 2025. CTA buses have an operating lifespan of 14 years, so these new diesel buses will continue to emit dangerous greenhouse gases for almost the entire decade of the 2030s.
