An A to Z of Fossil Fuel Industry Deception

Union of Concerned Scientists

This year has brought new evidence of what major fossil fuel companies knew and when about the role their products play in climate change, as well as what they did in spite of what they knew. But these technologies are no substitute for sharp cuts in fossil fuels if we keep the goals of the Paris climate agreement within reach.

Something Stinks: California Must End Manure Biomethane Accounting Gimmicks in its Low Carbon Fuel Standard

Union of Concerned Scientists

Each credit one metric ton of carbon dioxide equivalent pollution below the standard. I’ve written recently about why a Cap on Vegetable Oil-Based Fuels Will Stabilize and Strengthen California’s Low Carbon Fuel Standard , which addresses the bio-based diesel credits.

Glossary of Greenhouse Gas Terms

Greenbuilding Law

Atmosphere The gaseous envelope surrounding the Earth. The dry atmosphere consists almost entirely of nitrogen (78.1% volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone.

Three sustainable fuels that could be the future of green aviation

A Greener Life

of the world’s total carbon dioxide emissions from fossil fuel combustion, many airlines are considering carbon-capture-and-storage technologies and electric-powered planes. In April, Air Canada committed to investing $50 million in SAFs and other carbon-reducing technologies.

The Real Cost of Food

Acoel

Less than a quarter of cropland is devoted to food directly eaten by humans, with the rest going to mostly to animal feed and biofuel feedstock, and it takes many pounds of grains to produce a pound of beef. Bovine guts generate methane, which is 85 times more powerful than carbon dioxide over 20 years.

Space for all: here are some of the huge commercial opportunities away from Earth

Physics World

Weighing just 260 kg each, they will fly in very-low-Earth orbit at heights of roughly 550 km, which means that atmospheric drag will pull them down within a few years so they don’t end up as yet more space junk. Of course, there is an environmental cost to space, with most launches relying on fossil fuels.

U.S. Pushes Farmers to Develop A New Crop: Energy

Circle of Blue

The law provides $140 billion in tax incentives, direct loans, and grants to replace fossil fuels with cleaner renewable energy that lowers emissions of carbon dioxide. Gevo asserts its “farm-to-flight” project will release 80 percent less carbon dioxide to the atmosphere than ethanol produced by a conventional plant.
