What type of buses is the CTA focusing on to meet environmental standards?

The CTA is focusing on hybrid and electric buses to meet environmental standards for several reasons. These types of buses significantly reduce greenhouse gas emissions compared to traditional diesel buses, which directly contributes to improved air quality in urban areas. Hybrid buses combine an internal combustion engine with an electric propulsion system, allowing for better fuel efficiency and lower emissions. Electric buses, on the other hand, produce zero tailpipe emissions and rely on electric power, which can be sourced from renewable energy. As cities increasingly prioritize sustainability and environmental responsibility, adopting hybrid and electric buses aligns with these goals and positions the CTA as a leader in environmentally friendly public transit solutions.

While standard diesel buses are common, they do not meet the same environmental standards as the more modern options. Compressed natural gas buses, while cleaner than diesel, do not offer the same level of emission reductions found with hybrid and electric models. Biogas-powered buses are also an alternative but are not as widely implemented or supported by the CTA's current strategies to transition to more sustainable transit solutions.
