The idea of painting our roofs and roads white to offset global warming is not new, but a recent study has calculated just how significantly white surfaces could impact greenhouse gas emissions. Last week, researchers at Lawrence Berkeley National Laboratory and UC Berkeley presented their study at California's annual Climate Change Research Conference in Sacramento. If the 100 largest cities in the world replaced their dark roofs with white shingles and their asphalt-based roads with concrete or other light-colored material, it could offset 44 metric gigatons (billion tons) of greenhouse gases, the study shows. That amounts to more greenhouse gas than the entire human population emits in one year, according to a recent article in the Los Angeles Times. The strategy could also offset the growth in carbon dioxide emissions, which account for about 75% of greenhouse gases, for the next 10 years.

A new study shows that Germany has already reduced greenhouse gas emissions to the level pledged in the Kyoto Protocol. But a greater reliance on coal-fired power plants may soon reverse the trend. When it comes to global warming and concurrent efforts to reduce the emissions of greenhouse gases, Germany has always tried to present itself as a leader. New data set to be released on Friday shows that the country has earned its bragging rights.

Are you looking for a career path that you have complete control over every part of the business? No more boss to worry about. Starting a greenhouse business may be something to consider.

New greenhouse gases emitted in making flat-screen televisions or some refrigerants might be capped under a planned U.N. treaty to combat global warming, delegates at U.N. talks in Ghana said on Friday. Emissions of the recently developed industrial gases, including nitrogen trifluoride and fluorinated ethers, are estimated at just 0.3 percent of emissions of conventional greenhouse gases by rich nations. But the emissions are surging.

Dubbed the "missing greenhouse gas," nitrogen trifluoride (NF3) was found by a recent study to have a global climate impact 17,000 times greater than carbon dioxide. The chemical is found in the LCD panels of cell phones, televisions, and computer monitors, as well as in semiconductors and synthetic diamonds. The chemical is not one of the greenhouse gases monitored by the Kyoto Protocol, due to the fact that LCDs were not produced in significant quantities when it was drafted.

An Australian climate lawyer says the G8 nations' commitment to a 50 per cent cut in global greenhouse gas emissions would require a much bigger reduction target for industrialised nations. Countries agreed at the G8 summit to a "vision" of halving greenhouse gas emissions by 2050.

California issues plan to slash greenhouse gas emissions Over the next 12 years, new regulations would seek to turn the climate change clock back to 1990 levels. More efficient electricity use, less traffic and cleaner cars are goals.

MOSCOW (Reuters) - Russia will not accept binding caps on its greenhouse gas emissions under a new climate regime, currently being negotiated to succeed the Kyoto Protocol after 2012, top officials said on Monday. Kyoto puts a cap on the average, annual greenhouse gas emissions from 2008-12 for some 37 industrialized countries, including Russia.

In the United States, the laws require compulsory reporting and verification of the greenhouse gas emissions generated by industries covered in both the voluntary and the regulatory sectors.

Disease spread to wild bees from commercially bred bees used for pollination in agriculture greenhouses may be playing a role in the mysterious decline in North American bee populations, researchers said on Tuesday.

An ever-present point of concern for the planet's future welfare, worries over damaging CO2 emissions could soon be a thing of the past thanks to a University of Calgary climate change scientist who's developed a machine capable of removing CO2 from the air. More pointedly, David Keith and a team of researchers working out of the University of Calgary have been diligently looking for a way to capture harmful greenhouse gas carbon dioxide (CO2) directly from the air by utilising "near-commercial" technology.

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

A bunch of polls have come out that find the public supports strong climate action in spite of aggressive and widespread Republican fear-mongering about energy prices. For instance, the new Washington Post/ABC poll of 1,072 Americans (here) found: While majorities across the board support government regulation of greenhouse gases, it peaks among liberals (88%) and under 30s (80%), vs. 61% of conservatives and 64% of seniors. Support also ranges from 85% of Democrats, 65% "strongly," to 64% of Republicans, 39% strongly. Concern about its cost is broader, and stronger, among those who'd presumably be hit hardest - lower-income adults.

An environmentalist-sponsored report claims that by 2050, the United States could sever ties with coal and nuclear power, draw nearly all its electricity from renewable sources and cut its greenhouse gas emissions by more than 80% -- all with existing technology and with a net gain of 14 million jobs to the domestic economy. The report, commissioned by Greenpeace and the European Renewable Energy Council and conducted by Germany's equivalent of NASA, was released this morning at a press briefing in Washington. It is heavy on charts and supporting data and transparent on some key assumptions. And its sponsors call its findings "conservative." At its core, the report envisions a steep drop in the United States' energy use, both in absolute terms and compared with International Energy Agency predictions -- driven by strict efficiency standards. It also projects dramatic changes in the nation's electricity mix, with wind and solar power mushrooming to replace coal, oil and nuclear sources that would gradually go offline.

Yet another announcement from Project Better Place, this time spreading their wings to Hawaii - Hawaii goes electric. California's announcement last month of its aim to turn San Francisco Bay into the world's electric car capital has been followed by Hawaii jumping on the clean energy bandwagon. The state spends up to $7bn (£4.75bn) a year on importing oil, and cars account for almost 20% of the state's greenhouse gas emissions. In a mirror of the Californian plans, the electric transportation company Better Place will aim to build a network of kerbside charging points across Hawaii and create the equivalent of filling stations, where electric car owners will be able to replace their flat batteries for fully charged ones. With a full charge, a typical car will be able to travel 100 miles, ideal for commuting around urban areas.

What does "energy policy" mean to you? Does it conjure up questions of national security and terrorism? Or is it more about promoting cheap, renewable fuels? Maybe your take is about climate change and reducing greenhouse gases? Despite the various interpretations of the issue, or perhaps because of them, energy policy ranked high on the priority lists of voters of both parties on Nov. 4. Much of the interest can be attributed to the record run-up in oil and gasoline prices earlier in the year, which have since fallen off by about half, but increased awareness of climate change also played a big role.

What if it were possible to bury carbon dioxide over a mile below a power plant in the second worst air basin in the United States? In 2011 the greenhouse gas will be pumped below a power plant in the southern San Joaquin Valley of California. Located in Kern County near Bakersfield, the Clean Energy Systems power plant is powered by different kinds of natural gas and oxygen. It produces five megawatts of energy, enough for 5,000 homes, but the carbon sequestration experiment will increase that to 50 megawatts.
