Hefty Carbon Tax Raised Norway's Emissions

Greenhouse gases up 15% despite system aimed to curb them

(Newser) - In 1991, Norway enacted a punishing carbon tax, but things haven’t turned out quite as expected, the Wall Street Journal reports.

Reusable Bags: A Tricky Shade of Green

Thicker plastic requires more energy to produce, decomposes slower

(Newser) - Reusable shopping bags are this year's “it” giveaway, but they may not be as green as their feel-good slogans—like “Save the world” and "I used to be a plastic bag"—claim. The problem is that old habits die hard—many people simply forget to reuse...

Oxford Revives Einstein's Greenie Fridge Design

Fridge cooled by pressure and vapor, not polluting freons

(Newser) - Oxford scientists are rebuilding one of Albert Einstein’s first inventions—a refrigerator cooled with pressurized gases—in a bid to replace today’s eco-unfriendly fridges, the Guardian reports.

France's 'Picnic Tax' Making Foes Antsy

'Green' levy aims to cut down on use of plastic forks, paper plates

(Newser) - A picnic tax? “We are doing it,” France’s environment minister said today, apparently unabashed at such a villainous plan. Actually, the levy isn’t as dastardly as it sounds—it’s actually a tax on the plastic and paper plates and utensils commonly used in picnics, the...

4 in 10 North American Fish Species in Peril

Invasive Species Getting Bad Rap: Scientists

Exotics can cause extinctions, but spur diversity, evolution, too

(Newser) - Invasive species don’t always spell disaster for native ecosystems and animal life, scientists say after a study of the process and its effects on New Zealand. More than 22,000 non-native plants have been introduced to the islands, the New York Times reports, and only three native species have...

Overgrown LA Tract Turns to 'Scape Goats

Animals offer a green solution to clearing thick weeds

(Newser) - The sight of 100 goats feasting through a weedy tract in downtown Los Angeles yesterday had commuters guessing whether the caprine contingent was part of a movie, performance art—or perhaps lunch.

Plans to Stop Global Warming Straight From Sci-Fi Novels

Geo-engineering offers promise for slowing climate change ... and fear of consequences

(Newser) - Scientists worry humans might not curb carbon emissions in time to save the planet from irreversible harm, and some have suggested a radical concept called geo-engineering, the Economist reports. Once the stuff of science fiction, geo-engineering would combat global warming by manipulating the environment. While promising, critics warn ecological consequences...

Boston Cabbies Torqued Ovah Hybrid Cah Mandate

Pricey hybrids a problem in Beantown

(Newser) - Boston’s cab drivers are furious over a new rule requiring all taxis to be hybrids by 2015, Wired reports. With rising gas prices already pressing the industry, cabbies are loathe to trade their $6,000 used Crown Vics for new $24,000 Priuses. Many also argue that the hybrids...

China Shifting Into Green Gear

Communists know they need knowledge-based economy
