Trash trucks powered by trash gas reduce emissions by 80-90 percent
Waste Management Inc. owns 1,000 trash trucks that run on natural gas, plus a bunch of landfills that are constantly pumping out natural gas as a natural product of the decomposition of organic waste. Closing the loop on this cycle is a no-brainer, but it took Waste Management a decade to perfect the technology required. Now they’ve got trash trucks that run on gas from the trash they carry.

Critical List: Australia will tax carbon; U.S. cars kill 32.5 trillion insects each year
This is a carbon tax: Australia is going to put a tax of $23 per metric ton on carbon emissions from 500 companies.
Hybrids and electric vehicles may no longer be legally allowed to slink quietly down the street, surprising pedestrians and dogs everywhere. The National Highway Traffic Safety Administration is proposing a rule requiring that the near-silent cars emit some sort of sound at low speeds.
The EPA is not happy with ExxonMobil and the company's plan to clean up the Yellowstone River. I mean, it’s in favor of cleaning up, it just thinks this particular plan stinks. -

Limitless supply of rare earth elements found in ocean — if we can get them
The seabed of the Pacific ocean contains 1,000 times as much tonnage of rare earth elements as all the deposits on land, says a new paper published in Nature Geoscience. The elements, which are key to cleantech innovations like solar panels, batteries and electric motors, have been in short supply lately as China, pretty much the world's sole supplier, clamps down on exports.
