Nationwide Vehicle Emissions Database Could Help Cities Curb CO2
2015-04-07 19:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Researchers at Boston University have created a nationwide database for determining how much carbon dioxide is produced by vehicle travel in U.S. cities and suburbs an essential part of greenhouse gas reduction efforts, they say. Encompassing 33 years of data, the system provides kilometer-by-kilometer views of vehicle emission trends from roads across the country. Those emissions account for 28 percent of all fossil fuel CO2 emissions in the U.S., the researchers note. The data highlight the ongoing...

CO2 Lenses and Mirrors support cutting and engraving.
2015-04-07 14:31:07| Industrial Newsroom - All News for Today
Designed for 200–500 W lasers, CO2 Lenses and Mirrors produce clean edge and cut up to 3 mm deep. Offered in 1–1.5 in. diameter sizes, lenses come in 1.5–5 in. focal lengths in 0.5 in. increments to assure intricate, detailed cuts or deeper and wider cuts, as required. Silicon mirrors range from 0.5 in. to 5 mm thick. Providing < 0.2% total absorption values, 40-20 scratch-dig surface quality, and <1/40th wave sphericity, lenses and mirrors conform to OEM ISO-10110 specifications.

Urban Sprawl, Cars Hamper Cities Best Efforts on CO2
2015-04-07 01:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: There's no way to drive around it: Commuting to work behind the steering wheel emits carbon dioxide and contributes to climate change. Dense cities are pretty good at keeping those tailpipe emissions low when measured on a per-person basis because many commuters often use trains and buses to get to work. Less dense cities, on the other hand, see more people driving to work from distant suburbs, usually leading to more tailpipe emissions. A Boston University study published Monday in the Proceedings...
