Obama Rejects Keystone XL
Pipeline, Ending a Seven-Year Battle
President Barack Obama has rejected a Canadian company’s request
to build the Keystone XL Pipeline, which would have carried 800,000 barrels of oil a day from Alberta’s tar sands to refineries on the U.S. Gulf Coast. The decision is a major victory for climate and conservation groups and burnishes Obama’s legacy in the battle to slow global warming. Obama’s announcement, made after a seven-year review by the U.S. State Department and other agencies, comes just weeks ahead of key United Nations climate talks in Paris. In remarks at the White House, Obama said that the economic benefits of building the pipeline were outweighed by the high environmental costs of helping move to market tar sands crude, whose production is among the most carbon-polluting on the planet. “The pipeline would not make a meaningful long-term contribution to our economy,’’ Mr. Obama said in remarks at the White House.

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.

rather than in previously developed, less-sensitive areas, according to a new study. Researchers at the University of California, Berkeley, said that of 161 planned or operating utility-scale solar power developments in the state, more than 50 percent are being located on natural shrub or scrublands, such as the Mojave Desert. About 28 percent have been built on agricultural land and 16 percent have been built in developed areas, according to the study
, published in the Proceedings of the National Academy of Sciences. The researchers said that it makes far more sense for the state’s robust solar power industry
to locate its installations on farmland, especially considering the severity of California's ongoing drought.

permanent prohibition on cars in its downtown area. The newly elected city council announced that the city would also build at least 60 kilometers (37 miles) of new bike lanes by 2019 and provide a “massive boost” of investment in public transportation. Business owners in central Oslo fear that the car ban will reduce revenues, but leaders of the new council said the ban could even increase visitors to downtown and that the city would take steps to reduce negative impacts, including allowing vehicles to transport goods to stores and conducting trial runs of the ban to work out problems. Oslo, with 600,000 inhabitants and almost 350,000 cars, would be the first major European city with a permanent central car ban.

Toyota Vows to Eliminate
Nearly All of Its Gasoline Cars by 2050
The global automobile giant, Toyota, has announced plans to steadily phase out production of gasoline-powered cars
and to slash emissions from its fleet by 90 percent by 2050. Speaking in Tokyo, Toyota executives vowed to work with government officials and other companies to replace internal combustion cars with hydrogen fuel cell vehicles and hybrids. “You may think 35 years is a long time, but for an automaker to envision all combustion engines as gone is pretty extraordinary,” said a senior Toyota executive. The company said that by 2020 annual sales of its hybrid vehicles will reach 1.5 million and sales of fuel cell vehicles will hit 30,000 — 10 times the projected figure for 2017. Meanwhile, Volkswagen, shaken by scandal over falsifying emissions data on its diesel cars, announced it will increasingly shift production
to hybrid and electric vehicles.

‘Land Grabbing’ Is Accelerating
As Pressure on Agriculture Resources Grows
An area about the size of Japan — roughly 140,000 square miles — has been purchased or

leased by foreign entities for agricultural use during the last 15 years, according to a report
by the Worldwatch Institute. An additional 58,000 square miles are under negotiation, the report found. “Land grabbing,” a term for the purchase or lease of agricultural land by foreign interests, has emerged as a threat to food security in several nations. Globally, over half of this land is in Africa, especially in water-rich countries like the Congo. The largest area acquired in a single country is in Papua New Guinea, with nearly 15,500 square miles (over 8 percent of the nation’s total land cover) sold or leased to foreign entities. Foreign purchase of land in developing countries has surged since 2005 in response to rising food prices and growing biofuel demand in the U.S. and the European Union, as well as droughts in the U.S., Argentina, and Australia. “Essentially no additional suitable [agricultural] land remains in a belt around much of the middle of the planet,” writes Gary Gardner, a contributing author to the report.

Styrofoam May Be Biodegradable
After All, Thanks to Mealworms, Study Says
Mealworms can survive on a diet of polystyrene plastics — commonly used to make Styrofoam — according to research published in
Mealworms devouring Styrofoam
the journal Environmental Science and Technology
. The findings point toward a possible solution for dealing with one of the most-polluting forms of plastic. In the study, 100 mealworms consumed between 34 and 39 milligrams of Styrofoam per day. These worms were as healthy as those fed a normal diet, the researchers report, and excreted biodegraded Styrofoam fragments that were usable as agricultural soil. While studies have found that other organisms, including waxworms and Indian mealmoth larvae, are able to digest plastics such as polyethylene, this is the first organism able to digest Styrofoam, which is generally considered non-biodegradable. The discovery could aid in better understanding of the conditions and enzymes that contribute to plastic degradation.

Liaoning Province ranks sixth in China in terms of aquaculture production, and this group of fish farms, which face the Yellow Sea, is the largest set constructed along the province's coastline. The fish farm basins are built on shallow seabeds, mudflats, and bays. Outer barriers protect the basins from winter storms and large waves generated by passing ships. Most aquaculture products are purchased live in China, with less than 5 percent being killed and processed for selling in local or foreign markets, the U.N. Food and Agriculture Organization (FAO), says. Shellfish, a traditional marine food source, still dominates China's marine production, according to the FAO's Fisheries and Aquaculture Department, accounting for 77 percent of the market.

Researchers from the Johns Hopkins Center for a Livable Future estimated the edible U.S. seafood supply at 4.7 billion pounds a year, and said that 2.3 billion pounds of that are wasted. The study, published in the Journal Global Environmental Change
, said that 573 million pounds are lost annually as commercial fisherman catch and discard the wrong species. Roughly 330 million pounds are lost during distribution and retail, and 1.3 billion pounds are lost at the consumer level. The researchers recommended a number of changes to reduce the waste, including stricter limits on by-catch by commercial fishermen and efforts to encourage consumers to purchase frozen seafood.
Interview: A Scientist’s View
On How to Repair the Planet
For an environmental scientist who studies how humanity is pushing the earth close to potentially disastrous tipping points, Johan Rockström
of a new book, Big World, Small Planet
— is surprisingly optimistic. Although he reckons that our species has crossed four of nine “planetary boundaries,” including those on climate change and deforestation, he believes there is still time to pull back from the brink and create a sustainable future based on renewable energy and a “circular” economy that continually reuses resources. In an interview with Yale Environment 360
, Rockström describes how an alignment of science, technological advances, and a growing public hunger for action can get civilization back on track. “It’s not a journey where we are backing into the caves,” says Rockström. “It’s a journey of high technology ... and huge, multiple benefits.”

Chaotic Illegal Timber Trade
Threatens Crucial Forests in Southeast Asia

dollars annually, making it one of the world's largest illegal timber schemes, according to a new analysis by the Environmental Investigation Agency
(EIA). At stake are some of the most ecologically important remaining forests in Southeast Asia, EIA says. The report documents how Chinese businesses pay in gold bars for the rights to log entire mountains and smuggle timber out of Myanmar's conflict-torn state of Kachin. The stolen timber, primarily high-value species of rosewood and teak, is increasingly being sourced from deeper within Myanmar to feed factories in south and east China. The trade appeared to have peaked in 2005, when 1.3 million cubic yards of logs crossed the border. A brief hiatus then occurred when Chinese authorities intervened, but the scale is once again nearing peak levels, the EIA says.

Unchecked Consumerism Causing
Record-Breaking Resource Use, Study Says
Consumption of critical global resources — from meat and coffee to fossil fuels and water — has peaked in recent years, accelerating

climate change, pollution, and resource depletion to unsustainable levels, according to an analysis
by the Worldwatch Institute. The report tracked 24 global consumption trends and found many of them to be record-breaking. Meat production, for instance, has more than quadrupled in the last 50 years, leading to large-scale pressure on water, feeds, and grazing land. Aquaculture production has increased roughly 10 fold since 1984, and today farmed fish account for nearly half of all fish eaten. Global plastic production has also risen continuously over the past 50 years, while recycling rates remain very low. In the United States, for example, only 9 percent of plastic was recycled in 2012. “Untrammeled consumerism lies at the heart of many of these challenges,” said author Michael Renner.
Forum: What the Pope Should
Say in His Upcoming UN Address
In his June encyclical, Pope Francis issued a call for robust individual action and a sweeping transformation of global economic and
political systems to deal with the dual threats of climate change and environmental degradation. On Sept. 25, he will bring aspects of that message to the United Nations. Yale Environment 360
asked leading thinkers on the environment and religion what they would like the pope to say before the U.N. While many said the pope’s encyclical was a potentially transformative moment for stewardship of the planet, others would like Pope Francis to speak out about issues he overlooked or dismissed, including the role of population growth in environmental problems and the vital part that the private sector must play in combating global warming.

Flooding Fields in Winter May
Help California Water Woes, Study Suggests

from a study by University of California, Davis, researchers. Winter months, when crops are dormant, typically see more precipitation than summer months, when crops are actively growing and farmers rely on groundwater reserves for irrigation. Several water districts have attempted to sequester excess surface water during storms and floods by diverting it into infiltration basins — confined areas of sandy soil — but those basins are scarce. Instead, researchers suggest that some some 3.6 million acres of farmland could serve a similar purpose — particularly fields of wine grapes, almonds, peaches, and plums — because those lands allow deep percolation with little risk to crops or groundwater quality.

has grown on the anchovies, sardines, and other species used to make feeds for farmed fish. Now, however, researchers are rapidly developing nutritious plant-based food that can put the aquaculture sector on a more sustainable path. Using protein-rich legumes such as soybeans and combining them with various oil-rich supplements, scientists say they are steadily moving toward all-vegetarian diets for aquaculture fish. “I was told by many [people] that fish require fishmeal because that’s what they eat in the natural world,” says one leading researcher. “But that’s just wrong.”
Solar Decathlon: The Search for
The Best Carbon-Neutral House
What’s the latest in well-designed, energy-efficient solar homes? The U.S. Department of Energy has invited 15 teams from colleges across the country to design and build affordable, energy-efficient, and attractive solar-powered houses for the 2015 Solar Decathlon. In addition to functioning as comfortable homes, the houses in the competition must produce at least as much energy as they consume. Here, e360
takes a look at some of this year's entries, which will be on display in Irvine, California, this October. These houses have been engineered to not only embrace energy efficiency and sustainable design, but also to meet the diverse needs of their future inhabitants, from food production to storm protection and disaster relief.

Global Population Projected to
Reach 11 Billion by 2100, U.N. Estimates
The current world population of 7.3 billion is expected to reach 8.5 billion by 2030, 9.7 billion by 2050, and 11.2 billion in 2100,
according to a United Nations report
released today. The revised U.N. estimates counter previous projections, which had said that global population would peak at roughly 9 billion by 2050, then gradually decline. Most growth will occur in developing regions, the new report says, especially Africa, which is expected to account for more than half of the world’s population growth between 2015 and 2050. India is expected to become the most populous country, surpassing China around 2022. Nigeria could surpass the United States by 2050, which would make it the third-largest country in the world, the United Nations projects.
Interview: How an Indian Politician
Became an Environmental Hawk
Jairam Ramesh was a self-described “economic hawk” when he became India’s environment minister in 2009, figuring that the
country’s ecological problems could wait as India lifted its people out of poverty. But by the time he left his post in 2011, he had become an environmental hawk after witnessing how India’s rapidly expanding economy and soaring population had caused widespread pollution and destruction of the environment. In an interview with Yale Environment 360
, Ramesh — an economist, parliament member, and author of a new book — talks about why a “grow-now, pay-later” philosophy is unsuitable for India and discusses his own brand of GDP, which he calls Green Domestic Product. “In the mad rush to economic growth ... we are destroying foundations of ecological security,” he says.

Rain Harvesting Could Provide
Major Economic Benefit in India, Study Finds
Collecting precipitation in rain barrels could result in significant savings for many people in India, according to
an analysis of
precipitation data collected by a NASA satellite. Estimates showed that harvested rain could provide at least 20 percent of average indoor water demand, or entirely irrigate a household vegetable garden. The savings associated with a vegetable garden could be between 2,500 and 4,500 rupees per year (39 to 71 U.S. dollars) — an amount equivalent to half a year’s rent in an average 1-bedroom apartment in an Indian city. In a country where the distribution of potable water is a challenge, rainwater is an untapped resource that could provide significant benefits, the researchers write in the Urban Water Journal

Pope Francis released today
his highly anticipated encyclical, which is largely focused on halting climate change and
environmental degradation and emphasizes the importance of protecting impoverished communities from the worst effects. This is the first such letter from a leader of the Catholic Church to address environmental issues, analysts say. “Climate change is a global problem with grave implications: environmental, social, economic, political,” Pope Francis wrote. “It represents one of the principal challenges facing humanity in our day.” Industrialized countries are responsible for most of the damage, he said, and are obligated to help developing nations cope with the looming crisis. Within the document, he delves deeply
into both climate science and economic development policies, and chides climate change skeptics for their "denial."

The analysis considered how much cars cost society and how they compare to bicycles in terms of air pollution, climate change, noise, road wear, public health, and congestion in Copenhagen. If the costs to society and the costs to private individuals are added together, the study found, the economic impact of a car is 0.50 euros per kilometer, whereas the cost of a bicycle is 0.08 euros per kilometer. Looking only at costs and benefits to society, one kilometer by car costs 0.15 euros, whereas society earns

based on data from industry and the Indonesian Ministry of Forestry. If Indonesian forestry industries operated at capacity, 41 percent of the wood supply would be illegal, the analysis found, and if companies were to go forward with plans for new mills, the supply would be 59 percent illegal. The source of this illegal wood is unclear, but the report suggests it is likely harvested by clear-cutting natural forests for new oil palm and pulp plantations. Part of the problem, the report says, is that Indonesia's sanctioned forestry plantations — the country's primary source of legal wood — are not currently sustainable because they are producing wood at only half the predicted rate.
