In terms of your daily environmental footprint, the vehicle you drive is a contributor. A typical passenger vehicle emits roughly , with the average passenger vehicle emitting about 0.9 pounds of CO₂ per mile.
At United, our purpose of “Connecting People. Uniting the World.” extends beyond just getting you to your next destination. Our commitment to mitigating our environmental impact means understanding our climate impact, holding ourselves accountable, and working to chart a more sustainable course for the future of air travel.
One day in late November, I cradled a red Samsung flip phone in my hands as if it was a ruby gemstone. To me, it was just as precious. Deep inside an overstuffed dresser in my childhood bedroom, I had spotted the glint of my first-ever cellphone, a Samsung SGH-A707 purchased in the waning days of the George W. Bush presidency. The device, no bigger than a credit card, had long ago succumbed to the spider web of cracks on its screen. For a moment, I was brought back to life before the smartphone, clicking the phone’s plastic keys for the first time in more than a decade.
Butanol, a 4-carbon alcohol (butyl alcohol), is produced from the same feedstocks as ethanol, including corn grain and other biomass. The term biobutanol refers to butanol made from biomass feedstocks. The benefits of biobutanol, when compared with ethanol, are that biobutanol is immiscible in water, has a higher energy content, and has a lower Reid vapor pressure. Under the Renewable Fuel Standard, corn grain butanol meets the renewable fuel 20% greenhouse gas emission reduction threshold.
A multidisciplinary approach has enabled researchers with the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) to quantitatively define the relative positioning and arrangement of the polymers in Populus wood and to create a computer model that details the findings.
Motorsport has been an object of fascination and admiration for fans worldwide for more than one hundred years. Since cars have taken to the streets, people have been keen on racing them. This has evolved over the years as automobile technology has developed and become more sophisticated, with the cars racing at the highest levels routinely clocking more than two hundred miles per hour.
An ongoing study dedicated to identifying and accessing renewable energy source options suggested switchgrass could be a contender.
WASHINGTON, Dec. 20, 2022 – The U.S. Department of Agriculture (USDA) today announced an investment of $9.5 million to support the scale-up of sustainable bioproduct manufacturing in the United States. Three successful projects are funded through USDA’s National Institute of Food and Agriculture’s (NIFA) Bioproduct Pilot Program, which funds research and development of value-added products from agricultural commodities.
When it comes to making fuel from plants, the first step has always been the hardest — breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.
The U.S. Department of Energy Bioenergy Technologies Office (BETO) empowers energy companies and aviation stakeholders by supporting advances in research, development, and demonstration to overcome barriers for widespread deployment of low-carbon sustainable aviation fuel (SAF).
