环境污染的隐性代价
We often hear about the economic costs of environmental regulation on the energy industry.
But there's a flip side to that equation—the price society pays for pollution. One scientist has added up those costs. And she found they're going down.
Modeling the hidden costs of pollution
For years, scientists have known that pollution from burning fossil fuels is bad for us.
But can we place a dollar amount on the hidden costs of burning coal and other fossil fuels for electricity?
One person who wanted to know was Paulina Jaramillo, a Carnegie Mellon scientist. She studies how energy systems impact the environment.
Jaramillo called up a colleague. They designed a model to figure out those hidden costs.
The researchers plugged in pollution reports from the EPA, weather models and population data. They took into account the effects of pollution on crops, forests, and infrastructure. They also took into account how pollution affects human health.
Much of that cost hinges on one basic number. And it's kind of creepy number.
"Value of a statistical life—which is a number widely used in policy analyses to estimate mortality costs," she says.
The value of a statistical life is basically the amount of money we as a society are willing to spend to save someone's life. And according to the federal government, it's around $6 million these days.
How the cost of pollution has decreased
Since the early 2000s, emissions from sources like coal-fired power plants have been going down. And because of this, Jaramillo found that the annual cost of pollution declined from 2002 to 2011 by about 25 percent, to $130 billion.
"Because we started reducing those emissions, we reduced health impacts," she says. "These models cannot pinpoint who has specifically benefited, but on a population basis there are benefits."
Those benefits include fewer heart attacks and fewer ER visits for asthma that can be triggered by air pollution.
So, what happened?
Jaramillo says the big change is that new regulations forced many coal-fired power plants to clean up.
The Great Recession lowered demand for a few years, and cleaner sources, like natural gas, have cut into coal's share of the electricity market.
These costs of air pollution may be going down, but the price tag the researchers calculated is still around $400 per year for every person in the U.S.
This research was published in the journal Energy Policy.

rban residents in poor countries are by far the worst affected, the WHO said, noting thatnearly every city (98 percent) in low- and middle-income countries has air which fails to meetthe UN body's standards. That number falls to 56 percent of cities in wealthier countries.
据世界卫生组织表示，目前，贫穷国家的都市居住者面临的状况最糟。该报告指出，中低收入的国家几乎每座城市(98%)的空气质量都未达到联合国机构的标准。而富有国家的这一比例则降到了56%。
"Urban air pollution continues to rise at an alarming rate, wreaking havoc on human health,"Maria Neira, the head of WHO's department of public health and environment, said in astatement.
世界卫生组织公共卫生与环境部门主任玛利亚·尼拉在一份声明中表示：“都市空气污染程度持续以惊人的速度增长，这对人体健康构成威胁。”
The UN agency's latest air pollution database reveals an overall deterioration of air in theplanet's cities, and highlights the growing risk of serious health conditions also including strokeand asthma.
世界卫生组织最新的空气污染资料库显示，全球城市整体空气质量恶化，并强调居民罹患严重健康疾病如中风、气喘的风险也在增加。
Tracking the prevalence of harmful pollutants like sulfate and black carbon, WHO found that airquality was generally improving in richer regions like Europe and North America, but worseningin developing regions, notably the Middle East and southeast Asia.
通过追踪如硫酸盐、黑碳粒子等有害物质，世界卫生组织发现，富有区域如欧洲与北美的空气质量大致改善，但发展中地区的情况则趋向恶化，特别是中东与东南亚。
Overall, contaminants in outdoor air caused more than 3 million premature deaths a year, theUN body said.
世界卫生组织表示，整体而言，户外空气污染物质已导致每年超过300万人早死。
The quality of air pollution data provided by individual countries varies considerably, and WHOdoes not compile a ranking of the world's most polluted cities.
由于各个国家提供空气污染数据的依据差别相当大，所以世界卫生组织并未对全球污染最严重的城市进行排名。
But, in a sample of selected mega-cities with a population above 14 million, New Delhi was themost polluted, followed by Cairo and Bangladesh's capital Dhaka. Beijing was listed the sixthmost polluted city and Shanghai the seventh.
不过，在挑选的城市人口超过140万的特大都市样本中，印度的新德里是污染最严重的，紧随其后的是埃及的开罗和孟加拉国的首都达卡。北京、上海分别排名第六和第七位。
A sample of European data showed that Rome had slightly worse air than Berlin, followed byLondon and Madrid.
而根据欧洲数据样本显示，污染最严重的城市依次是罗马、柏林、伦敦和马德里。
