Virgin Atlantic: Emissions from Steel Mills Could Fuel Airplanes
September 16, 2016 01:32 PM - by Leon Kaye, Triple Pundit

After five years of research and development, Virgin Atlantic and one of its clean-technology partners, Illinois-based LanzaTech, developed a source of jet fuel made of waste gases from steel mills. According to the companies, this new source of jet fuel passed extensive tests that both delivered on performance and promise to result in carbon emissions savings of 65 percent compared to conventional jet fuel.

This discovery comes at a time when airlines, seeking to mitigate what is a carbon-intensive business, have long dabbled with jet fuel blended with algae and other biofuels. The Dutch carrier KLM experimented with algae fuel blends, has flown transatlantic flights using blends of kerosene and cooking oil, and is still apparently committed to sourcing these fuels when available. Alaska Airlines also considered using recycled cooking oil to reduce its carbon emissions. Earlier this year, United kicked off flights between San Francisco and Los Angeles using a biofuel-conventional blend. Aviation fuel using feedstock from Brazilian sugarcane is also touted as an option.

Giant forest fires exterminate spotted owls
August 3, 2016 07:17 AM - University of Wisconsin-Madison

As climate changes and wildfires get larger, hotter and more frequent, how should public lands in the American West be managed to protect endangered creatures that, like the spotted owl, rely on fire-prone old-growth forests?

Could periodic forest thinning and prescribed burns intended to prevent dangerous “megafires” help conserve owls in the long run? Or are those benefits outweighed by their short-term harm to owls? The answer depends in part on just how big and bad the fires are, according to a new study.

In a report published Aug. 1 that may help quiet a long-simmering dispute about the wisdom of using forest thinning and prescribed burns to reduce the “fuel load” and intensity of subsequent fires, a University of Wisconsin—Madison research group has documented an exodus of owls following the fierce, 99,000 acre King Fire in California in 2014.

You Could Be Eating Endangered Fish Without Even Realizing It

Julie Rodriguez, Care2

When you go out for sushi or visit a seafood restaurant, how sure can you be that you’re really getting what you’ve ordered? Last week, Oceana released some shocking findings: Around the world, an average of one in five samples of seafood is mislabeled.

The report examined 25,000 samples worldwide and reviewed more than 200 published studies from 55 different countries. Every continent was represented apart from Antarctica. The mislabeling was present in every part of the seafood supply chain, including retail, wholesale, distribution, import/export, packaging, processing, and landing.

That’s bad news for many reasons – mislabeling makes dining dangerous for consumers (not all of these species are considered suitable for human consumption), and difficult for people who are trying to avoid mercury exposure or who simply want to dine more sustainably. In most cases, cheap fish were being passed off as more expensive varieties.
