Fueling Alternative Transportation with a Carbon Aviation Tax Act of 2025

# Fueling Alternative Transportation with a Carbon Aviation Tax Act of 2025 This bill would place a new tax on aviation fuel (jet fuel) to help reduce carbon emissions from flights and encourage the development of cleaner aviation alternatives. The tax would apply to commercial and private aviation operations. Revenue generated from the tax would be directed into a trust fund to support research and development of sustainable aviation fuels and other clean transportation technologies. The bill would primarily affect airlines, private aircraft operators, and ultimately airline passengers through potentially higher ticket prices.

The revenue could also fund programs aimed at environmental health, research into alternative fuels, and possibly transportation infrastructure improvements. According to the bill's subjects, it may also include provisions addressing how revenue is distributed, with potential consideration for low- and moderate-income communities. **Current Status:** The bill (S 173) is currently in committee, meaning it has been introduced but has not yet been debated or voted on by the full Senate. It was sponsored by Senator Edward Markey (D-MA) in the 119th Congress.
