Could This Straddling Bus Help
Solve China’s Air Pollution Problem?
With an estimated 20 million new drivers on the road each year, China has long struggled to control its CO2 emissions, air pollution, and traffic problems.
But a Beijing-based transit company is planning to test a new straddling bus this summer
that could provide some relief, according to Chinese news agency Xinhua. The bus, which can carry up to 1,400 passengers, hovers above the road, letting smaller vehicles pass underneath. Because it operates on existing roadways, the system is much cheaper to build than underground subways, while carrying the same number of people. The idea of a straddling bus has been around since 1969
, but has remained a far-fetched concept until recent years. A model of the system, designed by Transit Explore Bus, was unveiled at the International High-Tech Expo in Beijing this month. The company plans to build and test an actual straddling bus in Changzhou this summer.
Interview: CO2 'Air Capture' Could
Be Key to Slowing Global Warming
For two decades, Klaus Lackner has pioneered efforts to combat climate change by pulling carbon dioxide from the atmosphere.
Now, after years of watching the global community fail to bring greenhouse gas emissions under control, Lackner — director of the Center for Negative Carbon Emissions at Arizona State University — is delivering a blunt message: The best hope to avoid major disruptions from global warming is to launch a massive program of CO2 "air capture" that will begin to reverse the buildup of billions of tons of carbon in our atmosphere. "We need to have the ability to walk this backwards," says Lackner. "I'm saying this is a war, and we need to use all the weapons at our disposal. You don't want to get into this fight with one hand tied behind your back."

Obama Looking for Kids
As Science Advisors to the White House
White House advisors tend to be experts with decades of experience in specific fields, from foreign policy to education to energy.

But President Barack Obama announced this week
he’s looking for a much younger batch of consultants to advise the White House on science, technology, engineering, and math (STEM). The Kid Science Advisors outreach program will ask children which issues are most important to them and how to better engage students studying science to help guide White House policy and priorities. "The real reason we do this, as I’ve said before, is to teach our young people that it’s not just the winner of the Super Bowl or the NCAA tournament that deserves a celebration,” Obama said Thursday
. “We want those who have invented the products and lifesaving medicines and are engineering our future to be celebrated as well."

Brewing Company Creates
Edible Six-Pack Rings to Save Wildlife
Plastic six-pack rings have long been a nuisance to wildlife and ecosystems, fouling oceans and shorelines, and entangling and choking wildlife.
Now, a brewery in Florida has developed an edible version from the byproducts of making beer
, including wheat and barely. If not eaten by marine creatures, the six-pack ring biodegrades. Saltwater Brewery
3-D printed 500 of the holders in April and plans to scale up production to package all of its 400,000 cans of beer per month in the edible rings. The material is just as strong as traditional plastics, the brewery says, but is more expensive. The price would drop, however, as more companies use the edible rings, the brewery said. “We want to influence the big guys,” Chris Goves, president of Saltwater Brewery, said in a video about the new project. “And hopefully inspire them to get on board.”
Bringing Energy Upgrades
To the Nation’s Inner Cities
America’s low-income urban areas are filled with aging buildings that are notoriously energy-inefficient. It’s a problem that Donnel Baird sees as an opportunity. Baird is CEO and cofounder of BlocPower,
a startup that markets and finances energy-upgrade projects in financially underserved areas. Founded in 2013 with venture capital seed money, BlocPower bundles small energy-improvement projects together — from barber shops to churches —and sells them to potential investors. In an interview with Yale Environment 360
, Baird describes how BlocPower’s projects not only create jobs and reduce carbon emissions, but also raise awareness of global warming in inner-city communities. “It is not possible for the climate change movement to win anything significant without the participation of people of color,” says Baird.

Wooden Skypscrapers Grow in
Popularity in Effort to Reduce Emissions
Architects are increasingly abandoning traditional steel-and-cement skyscrapers in favor of wood-and-glue designs — a move that experts say could help drastically reduce CO2 emissions from the world’s building sector.
Acton Ostry Architects
Creating steel, iron, and non-metallic minerals — including concrete — is an energy-intensive process that accounts for more than 10 percent of global greenhouse gas emissions. In the 1990s, developers created a product known as cross-laminated timber — planks of wood glued together by a polyurethane adhesive — with the strength and durability of traditional building materials, and far fewer CO2 emissions. With concern for climate change mounting, wood-based skyscrapers have been popping up around the globe in recent years
. The University of British Columbia, for example, approved an 18-story, wooden housing complex in 2015. “This revolution has happened rather quietly and happened rather slow,” Kris Spickler, a heavy timber specialist at Structurlam, told Popular Science
. “But I think we’re in a year right now where we’re going to see it explode.”

A Town Made Almost Entirely Out
Of Plastic Bottles is Being Built in Panama
Construction has begun on the world’s first town made almost entirely out of recycled plastic bottles. Located on Isla Colón in Panama, the village will consist of 120 houses and a lodge on 83 acres of tropical jungle.
The first two-bedroom home was built late last year, and is made from 10,000 plastic bottles pulled from Panama trashcans, roadsides, and beaches. The walls of the homes consist of steel cages filled with bottles and then encased in a concrete mix. They are flexible enough to withstand an earthquake, and insulating enough to keep the home up to 17 degrees F cooler than the jungle outside. Because there are so many recycled bottles on the island already, homes can be built quickly and cheaply, said Robert Bezeau, founder of the Plastic Bottle Village. “We are changing the world, without changing the Earth, one home at a time,” he says on the project’s website

This amounts to approximately $16 billion a year for energy efficiency, renewable energy, and climate resiliency projects. In addition to its own financing, the World Bank said it would work to mobilize $25 billion in commercial funding for clean energy over the next five years. “If we don’t act, climate change threatens to drive 100 million more people into poverty in the next 15 years,” John Roome, senior director for climate change at the World Bank Group, said in a statement
. The new spending plan “will allow us to help developing countries more quickly, and in the areas where support is most needed, such as disaster preparedness, social protection, and coastal protection.”

The World’s Economy Grew,
But Greenhouse Gas Emissions Didn't
Despite a 3.1 percent growth in global GDP in 2015, greenhouse gas emissions remained flat for the second year in a row, according to the International Energy Agency.
A man installs new solar panels in Oregon.
The decoupling of emissions from economic growth is “welcome news,” IEA executive director Fatih Birol said in the press statement. “Coming just a few months after the landmark COP21 agreement in Paris, this is yet another boost to the global fight against climate change.” The world’s nations released 32.1 billion metric tons of greenhouse gases last year, equal to—or perhaps even a slight downtick from—2014, the agency said. The stabilization is likely due to the booming renewable energy industry and global cutbacks on the use of coal, particularly in the U.S. and China, the two largest emitters of carbon dioxide. Chinese emissions, for example, declined 1.5 percent last year.

already rapidly diminishing fish stock. Over the last 15 years, UNICEF and the government of Malawi have rolled out nine million free mosquito nets to guard the health of pregnant mothers, their offspring, and refugees against the ravages of malaria. This has been a public health triumph. But the mosquito nets are also being used by villagers for netting fish in Lake Malawi, contributing to the rapid decline of the lake’s fish stocks, which dropped 93 percent between 1990 and 2010, according to the UN’s Food and Agriculture Organization. Overpopulation and deforestation also contribute to the problem, but misuse of mosquito netting is playing a significant role.

China’s Wind Power Sector
Experienced Rapid Growth in 2015
China installed nearly half of all new global wind power generation
last year and added as much new wind energy capacity in one year as the total capacity of the leading U.S. wind-producing states — Texas, Iowa, and California. Bloomberg New Energy Finance reports that China installed nearly 29 gigawatts of new wind-power capacity last year, surpassing the previous record of 21 gigawatts in 2014. China’s new wind energy capacity dwarfed the next-largest market, the United States, which added 8.6 gigawatts in 2015. Analysts said China’s wind sector grew rapidly because of declining manufacturing and installation costs, generous government feed-in tariffs, improving transmission capacity, and the government’s campaign to curb pollution from coal-fired power plants.

General Electric Joins
The Move From CFL Bulbs to LEDs
General Electric, a leader in the lighting market, has announced that it will stop manufacturing compact fluorescent light (CFL) bulbs by the end of the year and
increasingly shift production to LED
(light emitting diode) bulbs, which last longer, produce a better-quality light, and are rapidly declining in price. The move highlights a trend away from CFL bulbs, which several years ago were the go-to choice for energy-saving bulbs to replace energy-intensive incandescent light bulbs. “Now is the right time to transition from CFL to LED,” said GE lighting executive John Strainic. The price of an LED bulb has fallen from $30 to $5 in recent years and continues to decline. Retail giant Ikea abandoned CFL bulbs last year and now sells only LED lights, and other major retailers like Walmart are expected to follow suit — a move welcomed by environmental groups, which laud the large energy savings from LEDs.

Rush to Electric Vehicles
Is Worsening Air Pollution in China
The push by the Chinese government and the country’s automakers to expand production of electric vehicles is actually worsening air pollution
and carbon emissions because most of China’s electricity is still produced by coal-fired power plants, new studies show. Thanks to government incentives, production of electric and plug-in hybrid vehicles is expected to grow six-fold to two million cars and trucks by 2020. But studies by researchers at Tsinghua University show that electric vehicles charged in China with coal-fired power produce two to five times as many particulates and other pollutants as gasoline cars. The Tsinghua studies call into question the government policy of promoting deployment of electric vehicles while the vast majority of the country’s electricity still comes from coal. “International experience shows that cleaning up the air doesn’t need to rely on electric vehicles,” said one analyst. “Clean up the power plants.”

Cost of Manufacturing Solar
Panels Is Projected to Continue Falling
The cost of manufacturing solar panels is dropping more quickly than previously predicted, putting solar energy on course to meet
20 percent of global energy demand by 2027, according to Oxford University mathematicians, who developed a new forecasting model
. By contrast, the International Energy Agency’s predictions are far more conservative, stating that by 2050, solar panels will generate just 16 percent of global energy demand. The Oxford researchers' model predicts solar panel costs will continue to decrease 10 percent a year for the foreseeable future. Their model draws on historical data from 53 different technologies. The findings should help refute claims that solar PV cannot be ramped up quickly enough, said Oxford's Doyne Farmer, who co-wrote the paper. “We put ourselves in the past, pretended we didn’t know the future, and used a simple method to forecast the costs of the technologies,” he said.

roads by now, U.S. Energy Secretary Ernest Moniz said
. In the summer of 2008, with gas prices hovering around $4 a gallon, Obama, then a candidate, set a goal of getting 1 million electric cars on the road by 2015, something he reiterated in his 2011 State of the Union address. Of the 250 million cars and trucks on U.S. roads, only 400,000 of them are electric. Sales fell six percent last year when compared to 2014, to about 115,000 vehicles, despite an increasing number offerings, often at sold at steep discounts. But cost remains an issue. Mostly due to the price of batteries, electric and hybrid cars often cost about $8,000 to $10,000 more than an equivalent gasoline-powered car.

New Device Harvests Energy From
Walking and Exercising, Researchers Say
Researchers at MIT have developed a new method
for harnessing energy
generated by very small bending motions, which could be capable
Schematic of new human energy harvester
of harvesting power from a broader range of natural human activities such as walking and exercising. Based on electrochemical principles — the slight bending of a sandwich of metal and polymer sheets, with materials similar to those in lithium ion batteries — the new technology can more effectively capture energy from human motions than previous devices. Those devices, which were based on frictional technology or the compression of crystalline materials, can capture energy from mechanical vibrations, but they are not as compatible with the pace of human movements, the researchers explain in the journal Nature Communications
. When bent even a very small amount, the new layered composite produces a pressure difference that squeezes lithium ions through a polymer. The process produces alternating electrical current, the researchers say, which can be used directly to power devices such as cell phones and audio players.

Graphene Membrane Can Clean
Nuclear Wastewater, New Research Shows
Microscopic graphene membranes can effectively filter radioactive particles from nuclear reactor wastewater
Microscopic image of graphene membrane
at room temperature, researchers from the University of Manchester have shown. Writing in the journal Science
, the researchers demonstrated that graphene membranes can act as a sieve, separating different varieties of hydrogen — both radioactive and non-radioactive isotopes — from water. The new technology could also be scaled to produce significant amounts of so-called "heavy water," which is a non-radioactive component that is required in large quantities to produce nuclear energy. The graphene technology is 10 times cheaper and more efficient than current methods of producing heavy water. "This is really the first membrane shown to distinguish between subatomic particles," said University of Manchester researcher Marcelo Lozada-Hidalgo.

Congressional Tax Credits
Expected to Further Boost U.S. Renewables
The renewable energy sector in the United States is finishing 2015 on a high note as Congress has voted to approve significant extensions for tax credits
for renewable energy, and the American Wind Energy Association (AWEA) has reported a surge in wind power installations.
Ending uncertainty about the fate of tax credits for the wind and solar industries, Congress has voted to extend investment tax credits for solar power and production tax credits for wind energy through 2022 and 2020, respectively. Renewable energy companies and analysts praised the extensions, saying that, coupled with rapidly falling prices for wind and solar energy technologies, the tax credits virtually guarantee a boom in the production of renewables in the U.S. Earlier this week, the AWEA said U.S. wind energy production has reached a milestone, with 50,000 turbines providing a generating capacity of 70 gigawatts — enough to power 19 million homes.

Accelerating Rock Weathering
Could Help Reduce Atmospheric CO2 Levels
Speeding up the naturally occurring process of weathering rocks to draw carbon dioxide out of the atmosphere could help to
Weathered limestone cliffs in Yorkshire, England
stabilize the climate and avert ocean acidification caused by greenhouse gas emissions, according to
research published in the journal Nature Climate Change
. As rainwater and other environmental conditions naturally break down rocks on the earth's surface, carbon dioxide is drawn from the atmosphere. The process converts CO2 to bicarbonate, a mineral that chemically binds CO2 and is washed away through rivers to the oceans. By modeling the large-scale effects of weathering — which is driven largely by precipitation, vegetation, and soil microbes — the researchers found methods for accelerating this CO2-removal system. Such a strategy could significantly counteract anthropogenic fossil fuel emissions, they say, slowing ocean acidification and protecting delicate ocean ecosystems such as coral reefs.

China and the U.S., with resulting declines in emissions for both countries. The fuel looks incompatible with a world that warms by no more than two degrees C, bringing calls for its rapid phaseout as the global economy is "decarbonized." But, with or without a deal in Paris later this week, will the calls be heeded? Has the demise of King Coal been greatly exaggerated? The smart money in Paris is betting that, despite the embrace of coal by some developing countries such as India and Turkey, the dirty fossil fuel’s days are numbered. "The inevitable conclusion we can draw on the future of global thermal coal is that it has none," an energy analyst said in Paris.

Yards away, a meeting of financiers and bankers got under way in which a central demand was for, well, much the same thing. Something strange has happened here. The masters of the financial universe are out in force insisting that, though they may not be waving placards or chanting slogans, they are part of the solution. Free markets could deliver a zero-carbon world, they say. And Mark Carney, the governor of the Bank of England and a leading player in the global financial system, announced the creation of a task force to develop a carbon-disclosure system that could force companies to reveal how heavily their businesses are invested in fossil fuels. He said it could become standard business practice around the world — carbon footprinting for financiers.

Paris COP21: For the Poorest
Nations, Questions of Compensation
In a series of side events on the first day of the Paris climate conference, U.N. Secretary-General Ban Ki-moon launched the
Initiative on Resilience, a program designed to help the world’s poorest countries, which are especially vulnerable to the ravages of global warming. Finance to help developing nations adapt to climate change is potentially the dealbreaker in Paris. Developing nations expect a Green Climate Fund, which would cover adaptation and the cost of moderating their greenhouse gas emissions, to contain $100 billion a year by 2020. If the money is not on the table, they may ditch their promises on emissions — and scupper the deal. Germany, France, and other developed nations promised help in Paris. But the president of Angola, chairing a group of 48 African nations vulnerable to climate change, said $5 billion of such projects were already on hold for want of cash.

research published in the journal Nature Climate Change
. Researchers developed a list of 14 strategies, all based on current technologies, that airlines could pursue to cut emissions, which account for roughly 2 to 3 percent of the total carbon dioxide added to the atmosphere each year. For example, one recommendation is to keep planes at the gate until takeoff rather than making them idle on the runway, or to use fewer engines — perhaps even electric engines — when taxiing. Emissions could also be cut significantly by reducing aircraft weight, the researchers say, such as by lowering the amount of extra fuel carried or replacing seats and brakes with ones made from lighter materials. Updating flight paths to more direct routes, adjusting altitude and speed to avoid drag-inducing turbulence, and retiring older planes would also cut costs and emissions.

time an animal with genetic alterations has been cleared for sale in supermarkets across the nation. A long and bitter battle
has surrounded the issue, and this approval comes five years after government reviewers deemed AquAdvantage Atlantic salmon, as the fish is known, safe for consumers and the environment. Opponents have argued that the genetic integrity of wild salmon could be threatened if the GM fish were to escape from contained farms into rivers and oceans. The company says, however, that the fish will be raised on land, thus making escape into the wild impossible, and that the GM salmon can be farmed more efficiently because they have a faster growth rate than conventionally farmed salmon.

Renewable Diesel Production and
Demand Growing Worldwide, Report Finds
A new type of renewable, non-petroleum-based diesel fuel is on the rise worldwide, according to the U.S. Energy Information Administration
with demand driven by mandates in multiple countries. Unlike other biofuels, renewable HEFA biofuels — the acronym stands for hydroprocessed esters and fatty acids, and the fuels are known as "renewable diesel" in the U.S. — are nearly indistinguishable from their petroleum counterparts, meaning they can serve as "drop-in" fuels, readily substituting for traditional diesel. For example, they can be used in diesel engines without the need for blending with petroleum diesel fuel. Worldwide, more than a billion gallons of HEFA fuels were produced in 2014. Ten plants worldwide now produce renewable diesel, and five additional projects are in development. Alaska Airlines, KLM, and United Airlines have demonstrated the use of HEFA biojet fuel on commercial flights since 2011.

Austria’s Largest State Now
Generates All Electricity from Renewables
The electricity supply in Lower Austria, the largest state in Austria, is now fossil-free,
state officials have announced. The state in northeastern Austria, which has a population of 1.65 million, now gets 63 percent of its electricity from hydroelectric power, 26 percent from wind energy, nine percent from biomass, and two percent from solar. While hydroelectric power has always generated a large portion of the state’s electricity, Premier Erwin Proell said that $3 billion in investments since 2002 in utility-scale solar and other renewables had helped the state reach the 100 percent renewables target. Proell said the expansion of renewables has created 38,000 green jobs in the state, with the aim of generating 50,000 jobs in the renewables sector by 2030. Throughout Austria, 75 percent of electricity generation now comes from renewable energy sources.

29 to 8.2 percent over the past decade, and the practice is gaining momentum under the guise of special infrastructure projects, according to information obtained
by the London-based advocacy group Environmental Investigation Agency (EIA). In 2013, Laos exported 1.8 million cubic yards of timber to Vietnam and China — more than 10 times the country’s official harvest, EIA found. Trade data also show that in 2014 China received $1 billion in illegal timber from Laos — a 22-fold increase from 2008. The high figures imply that the bulk of this timber is composed of valuable rosewood species, which are supposedly protected under Lao law. Virtually all logging operations are linked to infrastructure projects, especially hydropower dams, roads, mining, and agricultural plantations, EIA says.
