For the fourth year in a row, Europe has reduced its carbon dioxide emissions, with CO2 output falling by 1.3 percent in 2008.
The recession appears to be the main factor in the emissions reduction, as factories were idled across the continent. But European Union Environmental Commissioner Stavros Dimas said the EU’s emissions trading scheme and development of renewable energy sources also is playing a part in the reduction.
“This is a timely message to the rest of the world in the run-up to the Copenhagen climate conference,” said Dimas.

NPR’s Morning Edition recently aired this story, a variation on a theme that I have written about in the past on CleanTechies and in scholarly work: green backlash against renewable power. The Morning Edition piece focused on the land use implications of renewables, noting that it takes a lot more land to generate a terawatt of solar, wind or biofueled electricity than of coal or natural gas power.
True enough. But, for me, it all comes down to the threshold question: do you believe the worst-case climate scenarios? If your answer is yes, and you have the courage of those convictions, then you realize — as I have — that we have no choice, and no time to dawdle. People who answer that question affirmatively know that the paradigm shifts in energy production and consumption that are necessary if we are to have any chance of righting our climatological ship will face knee-jerk opposition and demagoguery from opponents (s, e.g., the spring time bloodbath over the Waxman-Markey bill). A movement that remains — however gallingly — on such tenuous footing cannot afford to endure the additional obstacle of in-fighting over policy nuances. To twist a familiar and over-used metaphor:

Author and scholar Michael Levi says in the current issue of Foreign Affairs that the odds of signing a climate treaty in Copenhagen this December are extremely small and argues that policymakers and environmental advocates should rethink their expectations for the summit.
Levi, a senior fellow for energy and environment at the Council on Foreign Relations, contends that the conventional treaty model – which focuses on high-level agreements on emissions caps and carbon trading schemes – is fundamentally flawed because emissions caps are largely unverifiable and unenforceable. Short of bullying with punitive sanctions, nothing can be done if caps are exceeded.

The U.K.’s Institute of Mechanical Engineers has proposed three geo-engineering schemes officials say could be immediately implemented to slow global warming: building artificial trees that absorb large amounts of carbon dioxide, using algae tubes to pull CO2 from the atmosphere, and painting the roofs of buildings white.
The engineers said that these three ideas, if carried out on a wide scale, could absorb much of the CO2 produced annually in the U.K. and cool temperatures.
The engineers shied away from more ambitious geo-engineering proposals — such as seeding the oceans with iron to encourage the growth of CO2-absorbing plankton — and focused instead on practical solutions that could be carried out soon.

For the first time, scientists have discovered chemicals used in a controversial natural gas drilling technique in water wells near the gas sites.
Scientists for the Environmental Protection Agency (EPA), testing wells near a major gas drilling area in Wyoming, have found traces of drilling chemicals in three wells, and other contaminants — including oil, gas, and heavy metals — in 11 of 39 wells recently tested, according to the Web site Pro Publica.
The chemicals are used in a process called hydraulic fracturing, in which drilling fluids and sand are injected under high pressure to break up rock and release gas.

Chris Tobias recently wrote about waste to energy in Singapore, illustrating the city’s exemplary response to fly ash left over from the incineration process. I just read an interesting French book on water, and one of the most interesting parts of the book was about Singapore.
Written by Erik Orsenna, a member of the prestigious Académie française, L’Avenir de l’eau (Water’s future) enables us to travel all around the world (albeit reading) and gathers facts and figures on how water issues differ from country to country.
Perfectly located between East and West Asia, Singapore is an important local hub for 4,000 international companies. The city’s geostrategic importance led to an important population boom, with the number of inhabitants climbing from 1.5 million at the time of independence in 1965 to more than 4.5 million today.
Despite receiving a lot of rainwater (there are 2,415 mm of precipitations per year, compared to roughly 500 mm for San Francisco and 1,200 mm for New York City), the city lacks water.
The precious liquid comes from four main sources: rain, water treatment, desalination and imports from Malaysia. (more…)

Facing the prospect that the federal government may soon begin regulating greenhouse gas emissions, the U.S. Chamber of Commerce is proposing a public hearing in which the chamber and allied scientists question whether human-caused global warming is real.
William Kovacs, the chamber’s senior vice-president for environment, technology, and regulatory affairs, is asking the U.S. Environmental Protection Agency (EPA) to hold the rare public hearing, complete with witnesses, cross-examinations, and a judge who would rule whether man is indeed warming the planet.
Kovacs likened the hearing to “the Scopes monkey trial of the 21st century,” referring to the famed 1925 court case in which a Tennessee teacher was illegally accused of teaching evolution. “It would be the science of climate change on trial,” said Kovacs, adding that if the EPA refuses to hold a hearing, the chamber will file a lawsuit in federal court challenging the notion of man-made global warming.

Oil exploration and production technology may hold the key to secure CO2 storage, a report published by the CO2 Capture Project (CCP) today highlights. The report provides a definitive treatment of the CO2 storage subsurface technical issues and how oil and gas experience technology and protocols are available now to address them.
Entitled “A Technical Basis for Carbon Dioxide Storage” it provides guidance on how to assess and manage industrial-scale CO2 Geological Storage (CGS) projects through appropriate site assessment, operational parameters and monitoring. The report covers four main areas: site selection; well construction and integrity; monitoring programs; and development, operations and closure.
Scott Imbus, CCP Storage Team Leader said: “With this report, the oil and gas industry is transferring decades of experience and nine years of technology development to the fledgling industry of CCS. We hope this will provide the critical boost to turn the potential of CCS into a practical reality.”

Singapore is a bustling city state at the southern tip of peninsular Malaysia. Independent from Malaysia since 1965, it has a dense population of 4.7 million people crammed into 269 sq. miles (697 sq. km)— that’s roughly 3.5x the size of Washington D.C.
In spite of its lacking land mass, the tiny country is a major economic hub in Southeast Asia and boasts one of the best standards of living of any Asian city, and even rivals many metropolis overseas.
It’s a city that is well planned, tightly regulated, visually attractive, and thankfully lacking the woeful pollution that afflict other centers like Hong Kong and Shanghai.
Waste and the City
All the economic activity and large population of course is not without its downside: waste. In 2008 the total volume of solid waste had reached 5.97 million tons. Luckily, according to government figures, roughly 2.24 million tons (approx. 56%) of this was recycled. That still left a lot left to deal with.
