Cleaner Buses in Developing World May Be Key for Climate

Like most thoroughfares in booming cities of the developing world, Bogotá’s Seventh Avenue resembles a noisy, exhaust-coated parking lot — a gluey tangle of cars and the rickety, smoke-puffing private minibuses that have long pBut a few blocks away, sleek, red vehicles full of commuters speed down the four center lanes of Avenida de las Américas. The long, segmented, low-emission buses are part of a novel public transportation system called bus rapid transit, or B.R.T. It is more like an above-ground subway than a collection of bus routes, with seven intersecting lines, enclosed stations that are entered through turnstiles with the swipe of a farecard and coaches that feel like trams inside. Versions of these systems are now being planned or built in dozens of developing cities around the world — Mexico City, Cape Town, Jakarta, Indonesia, and Ahmedabad, India, to name a few — providing a public transportation network that improves traffic flow and reduces smog at a fraction of the cost of building a subway.
But the rapid transit systems have another benefit: they may hold a key to combating climate change. Emissions from cars, trucks, buses and other vehicles in the booming cities of Asia, Africa and Latin America account for a rapidly growing component of heat-trapping gases linked to global warming. While emissions from industry are decreasing, those related to transportation are expected to rise more than 50 percent by 2030 in industrialized and poorer nations. And 80 percent of that growth will be in the developing world, according to data presented in May at a international conference in Bellagio, Italy, sponsored by the Asian Development Bank and the Clean Air Institute.
To be effective, a new international climate treaty that will be negotiated in Copenhagen in December must include “a policy response to the CO2 emissions from transport in the developing world,” the Bellagio conference statement concluded.
Bus rapid transit systems like Bogotá’s, called TransMilenio, might hold an answer. Now used for an average of 1.6 million trips each day, TransMilenio has allowed the city to remove 7,000 small, private buses from its roads, reducing the use of bus fuel — and associated emissions — by more than 59 percent since it opened its first line in 2001, according to city officials.
In recognition of this feat, TransMilenio last year became the only large transportation project approved by the United Nations to generate and sell carbon credits. Developed countries that exceed their emissions limits under the Kyoto Protocol, or that simply want to burnish a “green” image, can buy credits from TransMilenio to balance out their emissions budgets, bringing Bogotá an estimated $100 million to $300 million so far, analysts say.
Indeed, the city has provided a model of how international programs to combat climate change can help expanding cities — the number of cars in China alone will quadruple between 2002 and 2030, according to the International Energy Agency — pay for transit systems that would otherwise be unaffordable.
“Bogotá was huge and messy and poor, so people said, ‘If Bogotá can do it, why can’t we?’ ” said Enrique Peñalosa, an economist and a former mayor of the city who took TransMilenio from a concept to its initial opening in 2001 and is now advising other cities.
In 2008, Mexico City opened a second successful bus rapid transit line that has already reduced carbon dioxide emissions there, according to Lee Schipper, a transportation expert at Stanford University, and the city has applied to sell carbon credits as well.
But bus rapid transit systems are not the answer for every city. In the United States, where cost is less constraining, some cities, like Los Angeles, have built B.R.T.’s, but they tend to lack many of the components of comprehensive systems like TransMilenio, like fully enclosed stations, and they serve as an addition to existing rail networks.
In some sprawling cities in India, where a tradition of scooter use may make bus rapid transit more difficult to create, researchers are working to develop a new model of tuk-tuk, or motorized cab, that is cheap and will run on alternative fuels or with a highly efficient engine.
“There are three million auto rickshaws in India alone, and the smoke is astonishing, so this could have a huge impact,” said Stef van Dongen, director of Enviu, an environmental network group in Rotterdam, the Netherlands, that is sponsoring the research.
Bus rapid transit systems have not always worked well in cities that have tried them, either. In New Delhi, for example, the experiment foundered in part because it proved difficult to protect bus lanes from traffic. And a system that does not succeed in drawing passengers out of their cars just adds buses to existing vehicles on the roads, making traffic and emissions worse.
But with its wide streets, dense population and a tradition of bus travel, Bogotá had the ingredients for success. To create TransMilenio, the city commandeered two to four traffic lanes in the middle of major boulevards, isolating them with low walls to create the system’s so-called tracks. On the center islands that divide many of Bogotá’s two-way streets, the city built dozens of distinctive metal-and-glass stations.
Just as in a subway, the multiple doors on the buses slide open level with the platform, providing easy access for strollers and older riders. Hundreds of passengers can wait on the platforms, avoiding the delays that occur when passengers each pay as they board.
Mr. Peñalosa noted that the negative stereotypes about bus travel required some clever rebranding. Now, he said, upscale condominiums advertise that they are near TransMilenio lines. “People don’t say, ‘I’m taking the bus,’ they say, ‘I’m taking TransMilenio,’ ” he added, as he rode at rush hour recently, chatting with other passengers.
Jorge Engarrita, 45, a leatherworker who was riding TransMilenio to work, said the system had “changed his life,” reducing his commuting time to 40 minutes with one transfer from two or three hours on several buses. Free shuttle buses carry residents from outlying districts to TransMilenio terminals.
To the dismay of car owners, Bogotá removed one-third of its street parking to make room for TransMilenio and imposed alternate-day driving restrictions determined by license plate numbers, forcing car owners onto the system.
With an extensive route system, TransMilenio moves more passengers per mile every hour than almost any of the world’s subways. Most poorer cities that have built subways, like Manila and Lagos, Nigeria, can afford to build only a few limited lines because of the expense.
Subways cost more than 30 times as much per mile to build than a B.R.T. system, and three times as much to maintain. And bus rapid transit systems can be built more quickly. “Almost all rapidly developing cities understand that they need a metro or something like it, and you can get a B.R.T. by 2010 or a metro by 2060,” said Walter Hook, executive director of the Institute for Transportation and Development Policy, in New York.
Although TransMilenio buses run on diesel, their high-efficiency engines mean they emit less than half the nitrous oxide, particulate matter and carbon dioxide of the older minibuses. Cleaner fuels were either too expensive or did not work at Bogotá’s altitude, 9,000 feet above sea level.
TransMilenio is building more lines and underpasses to allow the buses to bypass clogged intersections, but for the moment the real challenge is overcrowding.
Juan Gómez, 21, a businessman, takes TransMilenio only on days when he cannot drive, and he griped that it was often hard to find a seat.
“It’s O.K., but I prefer the car,” he said.rovided transportation for the masses.

Climate impasse at G-8 summit leaves nations mired

Developing nations led by China and India refused Wednesday to back lofty but long-term targets proposed by the Group of 8 industrial nations to cut greenhouse gas emissions, balking at reluctance by leaders of the world's biggest economies to move more quickly on their own. Inability to bridge the gap between rising carbon-emitting countries such as China and the longtime polluters within the G-8 underscores the steep challenges involved in attempting to strike a comprehensive bargain to contain global warming.


The impasse comes down to the politically sensitive issue of who goes first.President Obama and his counterparts in the G-8, who are holding two days of meetings in the central Italian mountain town of L'Aquila, offered broad agreements to reduce greenhouse gas emissions by 2050. The statement pledged to slash global emissions by 50%, led by reductions of 80% by the G-8 countries.They also prepared to offer new financial incentives for developing nations to join the effort.
But the G-8 stopped well short of pledging to take aggressive action that could curb emissions more quickly -- at the cost of higher energy prices and a feared worsening of the global economy.And neither the broad promises of future action nor the relatively modest financial incentives were likely to break the standoff between the most advanced economies and the emerging powerhouses. Countries such as China, India and Brazil are unwilling to take the first steps to cut emissions that could choke off economic growth, instead demanding that wealthier nations take the lead."China's not going to do anything until the developed countries send a signal that they're going to do something," said Michael Oppenheimer, a geoscientist at Princeton University and a longtime participant in the Intergovernmental Panel on Climate Change.The standoff at the summit perpetuates a divide that must be bridged this year if there is to be a global agreement on curbing emissions.The United Nations is convening a meeting in Copenhagen in December aimed at forging a binding consensus on targets to reduce greenhouse gas emissions. But unless China and other developing nations can be persuaded to sign on to an accord, Obama may find it difficult -- if not impossible -- to convince Congress to go along.The stalemate on the international stage mirrors Obama's problem at home. Though the House approved a major climate bill last month, Republicans and other critics have unleashed a hailstorm of criticism. They argue that emissions limits by the United States and other advanced economies alone would have relatively little effect on global warming, while potentially harming the domestic economy.Obama's climate bill, which narrowly passed the House, could send a strong signal if it becomes law, said Dirk Forrister, who was chairman of the White House climate change task force under President Clinton and now is managing director of the financial firm Natsource LLC.But, he said, "the U.S. Senate will not go along with anything unless it sees some pretty serious action from developing countries." That, analysts say, sums up Obama's conundrum as he tries to push for a meaningful climate agreement during formal treaty negotiations in Denmark this winter. "It looks like it's going to be a pretty tough fight [in Copenhagen], based on what happened in these meetings in Italy," Forrister said.U.S. leaders hinted that a broad coalition of developing and developed nations could announce agreement today to team up on research on renewable energy and technology to scrub and store greenhouse emissions from coal. Michael Froman, Obama's point man at the summit and lead staff negotiator, argued that the major industrial nations' joint statement favoring an 80% reduction in their emissions by 2050 represented "significant cooperation" -- even though it came up short of the draft language that the White House had supported.The G-8 targets roughly followed those in Obama's domestic climate bill.The G-8 countries also set a global goal of 50% emissions reductions by mid-century, and declared that they recognized "the broad scientific view that the increase in global average temperature above preindustrial levels ought not to exceed" 2 degrees Celsius (3.6 degrees Fahrenheit).They did not announce any specific plans to cut emissions or adopt any short- or mid-term reduction targets. The United States pushed, and failed, to get developing nations to join in the reduction pledge. "In any negotiation, you put in a number of points," Froman said.

Sometimes they make it in and sometimes they don't." The statement that did not come -- the one that would have included China, Brazil and other developing countries -- is the one that matters, he acknowledged.

But both Froman and chief Obama climate negotiator Todd Stern argued that there was plenty of room to work out an agreement before the Copenhagen summit."It's a negotiation. Countries may make concessions further down the road," Stern said in an interview. Obama will chair a meeting of the world's largest emitters, including both developing and developed nations, today in Italy.
Analysts said the Obama administration could strengthen its hand in future negotiations with another victory or two at home -- Senate approval of a climate bill and, even better, passage by Congress of a conference version of the bill that Obama could sign into law before the Copenhagen talks."His most powerful weapon is a piece of signed legislation," said Melinda L. Kimble, senior vice president of the United Nations Foundation and a former climate negotiator in the Clinton administration. "If he has that in his pocket," she added, "everything else he has is icing on the cake."

Oregon Scientific Eco weather station ditches batteries

Oregon Scientific has announced the release of the +ECO Clima Control weather station, a new weather station that runs on solar power. Coming with a built-in solar panel, the new weather station gadget allows its users to monitor the current temperature and humidity in up to four locations within the home and outdoors. To do this, it uses remote wireless temperature and humidity sensors for up to 3 months from a single 8-hour charge. The new device, which is available in the US from this month, will be joined by two further eco-friendly devices in September, says the company. The +ECO Solar Weather Station promises to monitor current indoor and outdoor weather temperatures, humidity and shows an iconic future weather forecast, as well as Atomic time while the +ECO Solar Weather Clock will monitor the current indoor and outdoor weather temperatures and humidity, as well the Atomic time. Both products are equipped with detachable solar panels and remote wireless temperature and humidity sensors like the Clima Control offering. .

Japan considers adding noise to hybrid cars

It's been talked up before, but the transport ministry in Japan is currently seriously considering forcing car manufacturers of near-silent hybrid vehicles to add sound to their motors. "We have received opinions from automobile users and visually-impaired people that they feel hybrid vehicles are dangerous", a transport ministry official told the AP. "Blind people depend on sounds when they walk, but there are no engine sounds from hybrid vehicles when running at low speed". A panel of experts including the police and groups representing the visually-impaired have met to discuss the matter and, after the first meeting, decided that a "sound-making function" should be introduced. This would mean hybrid cars, such as the Toyota Prius, would be manufactured to create noise when in electric mode.

Ice caps are white, and reflect sunlight, much of which is reflected back into space, in turn cooling Earth; but with the ice caps melting, the only reflector is the ocean. Darker colors absorb sunlight, further warming the Earth.

Scientists blame global warming for the declining penguin population, as warmer waters and smaller ice floes force the birds to travel further to find food.

Stressed by cyanide fishing, harbor dredging, coral mining, deforestation, coastal development, agricultural runoff, careless divers, and now global warming, there is a devastating loss of coral across the world.

With accelerated global warming, and the ice covering melting, the earth would be absorbing more sunlight, and is on its way to becoming hotter than before.

Due to global warming the polar ice cap in the Arctic region is shrinking and rupturing; if this continues, summers in the Arctic would become ice-free by the end of this century.

Everytime we burn oil, coal and gas to generate electricity and power, we produce the heat trapping gases that cause global warming.

Deforestation is one of the main causes of atmospheric carbon dioxide; burning and cutting millions of acres of trees each year, it is responsible for 20-25 per cent of all carbon emissions.

Water vapor is the most prevalent and most powerful greenhouse gas on the planet; it holds onto two-thirds of the heat trapped by all the greenhouse gases.

Lawns only need watering once a week, post rain only after two weeks. Do watering early morning for minimal evaporation and water conservation.

Crawling traffic contributes eight times as much air pollution as traffic moving at regular highway speed.

Avoiding just 10 miles of driving every week would eliminate about 500 pounds of carbon dioxide emissions a year!

Turn off the tap when brushing your teeth and soaping your hands. This can save around 16 litres a day. That's 11,000 litre of water per person per year.

A dripping tap can waste over 20,000 litres of water every year.

Greenathon Impact: Solar lamps for students

In the shadow of the centuries-old fort of Pratapgarh, lies this village Guwada gujran which seems to be stuck in time. It's never known electricity.
Nights here would be spent in darkness or in the light of kerosene lamps and their toxic fumes.
But in the last two months, solar power lamps have changed the lives of the hundred-odd families in this village.
Guwada Gujran is one of the first villages taken up by TERI's Lighting a Billion Lives initiative - thanks to the money raised during the NDTV TOYOTA Greenathon, a 24 hour telethon for the environment held in February this year.
Giriraj Prasad, an entrepreneur, had heard about TERI's solar lamps from neighbouring villages where the project was implemented and had asked the NGO to come to his village as well. As the only person from Guwada attending college, he wants a better deal for the next generation.
"Children don't manage to study in the day as they have to work in the fields. People here don't understand what studying is. They think just going to school is enough. Now children can study a lot better," says Giriraj.
The lamps cost just 2 rupees a night to hire - much cheaper than kerosene.
Earlier Suman and Suresh would not be able to study at night as it was just too expensive for their families. But now, that's no longer a problem.

Greenathon impact: Lighting up 50 villages

The NDTV Toyota Greenathon is lighting up lives. Villages that would be plunged into darkness at nightfall are now riding on solar power which has replaced expensive and toxic kerosene lamps.
Guwada Gujran in Rajasthan is one of the first three villages to get solar power after the Greenathon through TERI's Light a Billion Lives initiative. And here's a look at the other villages that will soon be solar powered. Thanks to the Greenathon.
Fifty villages will soon benefit from solar technology. While most of them are in north India, villages in the south are also being identified.
NDTV's campaign raised 2 crore rupees in February and now work is on to spread the light. Lighting up each village takes about two months. Village communities, local NGOs and companies that make the solar lamps are all working together.
"The way the whole program works, there are three important stakeholders, bottom up - the community - someone needs to come forward and become the charging station operator. Second is the NGO partner because TERI is not present everywhere. And the third important stakeholder is the industry partner."
It's a slow process; but it is one that will surely light up lives for years to com
