"Blumreiter and Johnson co-founded ClearFlame Engine Technologies to market engine technology that allows trucks, generators and other motors to run on a variety of low-emissions fuels such as ethanol, methanol or liquid ammonia. While these fuels are not zero emissions, various studies have shown pure ethanol’s life cycle greenhouse gas emissions are roughly 40 percent to 50 percent less than petroleum-based fuel."

"CarbonBuilt spun out of UCLA’s engineering school in 2019. In May, the company began commercial production of its sustainable concrete at a partner facility in Alabama, where an on-site biomass furnace captures and supplies CO2. The company says it now plans to produce its Portland-cement-free blocks at ​'commercial volume' in Alabama starting in 2024."

"Based in San Juan, Puerto Rico, the company’s team of engineers, scientists, UX designers, and insurance experts are developing the next generation of parametric insurance in Florida, California, New York and Washington State. Raincoat partners with insurers, reinsurers, and governments worldwide in developing and distributing these solutions."

"Traditional methods of tracking biodiversity include metabarcoding, a type of analysis that looks at short snippets of DNA to identify specific populations of species. The researchers found that bioacoustic monitoring led to similar findings as this more direct method but can be accomplished at a lower cost and with less intrusion on the environment."

"'Ultimately, our plan, our goal would be to develop a credibly lower-cost process to make Portland cement at scale. And, therefore, because it’s lower cost, eventually, our process will replace 100% of cement production facilities worldwide, leading to a fully decarbonized system,' Finke said."

"'The green ammonia that Talus’s systems produce is both reliable and locally produced, which reduces costs by addressing supply chain insecurity and challenges,' Matt Carstens, Landus’s CEO and president, said in a response to questions. Green ammonia is 'an exciting innovation to consider,' he said."

"The 800,000-square-foot arena has a maximum capacity of 18,100 attendees and is the home of Seattle’s Kraken NHL team and a concert venue. The facility replaced the KeyArena and opened in October 2021. Amazon paid for its naming rights."

"Under the program set to begin next year, Duke will buy the new appliance or whatever improvements are deemed appropriate for participating households. Over the course of up to 12 years, customers then pay the company back through their utility bills. Even while paying the tariff, which includes the company’s 8.4% of return, the energy savings should lower their monthly costs by 10% or more."
