Bill Summary · SB 99

Legislative bill overview

SB 99 would prohibit the sale or use of fuels with a carbon intensity rating below zero in New Mexico. The bill targets negative carbon intensity fuels—those that remove more carbon from the atmosphere than they emit during production and use. This represents a significant restriction on certain low-carbon fuel technologies and carbon-neutral energy solutions.

Why is this important

Carbon intensity metrics are increasingly used in state and federal climate policies to incentivize cleaner fuels. Restricting negative-carbon fuels could undermine climate goals by eliminating incentives for advanced renewable fuels, hydrogen production, and biofuels with carbon capture. This decision affects New Mexico's energy market competitiveness and its ability to meet climate commitments while potentially impacting fuel innovation and investment.

Potential points of contention

  • Climate policy conflict: The bill contradicts most state and federal climate initiatives that actively promote negative-carbon fuels as essential climate solutions
  • Technology limitation: Restricts emerging fuel technologies (sustainable aviation fuel with carbon capture, advanced biofuels, green hydrogen) that major industries are adopting
  • Economic impact: May reduce investment in clean fuel development and related jobs in New Mexico's energy sector
  • Regulatory clarity: Unclear rationale for why negative-carbon fuels pose problems compared to merely low-carbon alternatives
