Sustainable aviation fuel is gaining momentum worldwide, but dedicated incentives alone are not enough. Clean Fuel Standards remain essential to scaling adoption and long-term investment.
Shouldn’t Every Day be Earth Day?
Today, heat-trapping pollution from over a century of combustion and emissions of greenhouse gases (GHG) threatens the survival of not only crops, plants, and countless insect, marine, and animal species, but also human life as we know it.
But unlike the 1970s, when there were literally no viable alternatives to oil, coal, and gas for our energy and transportation needs, in 2026 clean, renewable alternatives are abundant and often cheaper. The age-old, zero-sum arguments that pitted environmental against economic interests, are moribund.

The report adds to growing evidence that clean fuel standards can expand fuel diversity and support consumers without the dramatic price impacts critics often predict.
