空氣污染已經(jīng)成為一個(gè)全球化的問(wèn)題，許多高度工業(yè)化現(xiàn)代化的大城市都面臨著嚴(yán)重的空氣污染，人們的健康和生命因此受到威脅。大多數(shù)地區(qū)已經(jīng)意識(shí)到空氣污染的嚴(yán)重性，并積極采取措施降低污染排放，凈化空氣質(zhì)量，下面來(lái)看看不同國(guó)家和城市的做法吧。

倫敦：推出空氣質(zhì)量警報(bào)系統(tǒng)

When a thick cloud of air pollution settled in over London last week, experts warned those with health problems to avoid strenuous exercise. The advice to Londoners essentially boiled down to this: breathe less.
上周，當(dāng)倫敦籠罩在污染嚴(yán)重的空氣中時(shí)，專家警告存在健康問(wèn)題的人應(yīng)避免劇烈運(yùn)動(dòng)。倫敦人得到的忠告基本上可歸結(jié)為：少呼吸。

Last week, London mayor Sadiq Khan rolled out a new system of air quality alerts at bus stops, Tube stations and roadsides, warning those who experience symptoms from air pollution to reduce strenuous activity. The mayor also announced a doubling of funding for reducing pollution.
上周，倫敦市市長(zhǎng)薩迪克?汗推出了新的空氣質(zhì)量警報(bào)系統(tǒng)，該系統(tǒng)可在公交車站、地鐵站和道路旁警告因空氣污染出現(xiàn)病癥的人們減少劇烈運(yùn)動(dòng)。他還宣布將用于減少污染的資金增加一倍。

But he does not have the legal authority to institute a ban, and has demanded the government take urgent action, including a diesel scrappage scheme.
但他沒(méi)有制定一項(xiàng)禁令的法律權(quán)力，他已經(jīng)要求政府采取緊急行動(dòng)，其中包括柴油車報(bào)廢計(jì)劃。

Cities around the world are confronting problems similar to London's. Some have been more aggressive than others, but overall, their experience shows that concerted steps to improve air quality do work, and they save lives.
世界各地的城市都面臨著與倫敦類似的問(wèn)題。有些城市表現(xiàn)的比其他地區(qū)更激進(jìn)，但總體而言，他們的經(jīng)驗(yàn)表明，改善空氣質(zhì)量的聯(lián)合措施有所見(jiàn)效，拯救了生命。

巴黎：公交免費(fèi)，車輛單雙號(hào)限行

Meanwhile, as Paris suffered a similar pollution episode - its worst in a decade - officials swung into action, waiving charges for public transport and restricting the number of cars allowed on roads, alternately barring those with odd and even license plates.
與此同時(shí)，巴黎也遭遇了近十年來(lái)最嚴(yán)重的類似空氣污染，政府立即采取行動(dòng)，取消了公共交通收費(fèi)，采取單雙號(hào)限行制度限制在道路上通行的車輛數(shù)量。

At the same time Paris mayor Anne Hidalgo joined officials from Madrid, Athens and Mexico City in announcing plans to get all diesel vehicles off the roads by 2025.
同時(shí)，巴黎市市長(zhǎng)安娜-伊達(dá)爾戈與馬德里、雅典以及墨西哥城的官員共同宣布，計(jì)劃在2025年前禁止所有柴油車上路。

Diesel is highly polluting, emitting far greater amounts of dangerous nitrogen dioxide and tiny pollution particles than petrol, and can cause cancer to heart attacks.
柴油污染十分嚴(yán)重，其有害二氧化氮及細(xì)微污染顆粒的排放量比汽油更大，并可能導(dǎo)致癌癥、心臟病。

Despite the health damage it wreaks, governments across Europe, including Britain's, have offered motorists tax incentives that effectively encourage the use of diesel, on the assumption – now being questioned - that it produces less planet-warming carbon dioxide than petrol.
盡管燃燒柴油會(huì)損害健康，但是基于柴油產(chǎn)生的溫室氣體二氧化碳比汽油更少這一假設(shè)，歐洲各國(guó)政府，包括英國(guó)，還是向司機(jī)提供稅收優(yōu)惠政策，以有效鼓勵(lì)他們使用柴油。如今，這一假設(shè)遭到了質(zhì)疑。

柏林：部分車輛安裝污染過(guò)濾裝置

Berlin is a notable exception to the story of the diesel disaster gripping much of western Europe. It has cleaned up its own fleet, installing pollution filters on buses and garbage trucks, and imposed tough rules on heavy goods vehicles. A strict emission zone bars older diesel vehicles, and rates of car use, which are already among the lowest in Germany, have dropped even further in recent years. Public transport is efficient and easy to use, with a two-hour pass costing just €2.70 (￡2.25).
大部分西歐國(guó)家都受到了柴油災(zāi)難的影響，而柏林卻是它們之中明顯的例外。柏林已經(jīng)整頓了該市的車輛，在公交車和垃圾車上安裝了污染過(guò)濾裝置，并對(duì)重型貨車實(shí)施嚴(yán)格的規(guī)定。該市有一個(gè)限制老式柴油車和汽車使用率的限制排放區(qū)，這里已經(jīng)是德國(guó)汽車使用率最低的地區(qū)之一，近年來(lái)使用率還在進(jìn)一步降低。公共交通高效且便利，兩個(gè)小時(shí)的通行成本只要2.7歐元。

As a result, levels of the tiniest, most dangerous particles, known as ultrafines, fell 70% in just three years, says Axel Friedrich, former head of transport and noise at the federal environmental agency, and an adviser to government and advocacy groups.
聯(lián)邦環(huán)境局交通及噪聲部前負(fù)責(zé)人兼政府和游說(shuō)組織顧問(wèn)阿克賽爾?弗萊德里奇表示，在短短三年內(nèi)，超微粒子的水平因此下降了70%，這是一種最細(xì)小最危險(xiǎn)的污染粒子。

波蘭克拉科夫：推進(jìn)燃煤取暖禁令

Kraków has the worst air in Poland - one of Europe's most polluted countries.
克拉科夫是波蘭空氣最差的地方，而波蘭是歐洲污染最嚴(yán)重的國(guó)家之一。

After a long legal fight, the city is now moving forward with a ban on burning coal for home heating, to take effect in September 2019.
經(jīng)過(guò)長(zhǎng)時(shí)間的法律斗爭(zhēng)，該市目前正在推進(jìn)燃煤取暖禁令，將于2019年9月生效。

紐約：改進(jìn)供熱系統(tǒng)

New York has also targeted heating systems. After an analysis found that 1% of buildings burning the dirtiest kinds of fuel oil, were producing more soot than all the city's traffic, officials made plans to gradually ban their use and to help landlords convert.
紐約也瞄準(zhǔn)了供熱系統(tǒng)。一項(xiàng)分析發(fā)現(xiàn)，有1%的建筑燃燒的是最不清潔的燃油，其產(chǎn)生的煙塵比全市的交通系統(tǒng)更多。紐約市官員們計(jì)劃逐步禁止使用這種燃油，并幫助房主改建取暖系統(tǒng)。

The changeover is already credited with saving hundreds of lives each year. It's just one piece of New York's air quality strategy, which also aims at slashing greenhouse gas emissions 80% from 2005 levels by 2050, says Mark Chambers, director of the mayor's Office of Sustainability.
這種轉(zhuǎn)變每年已經(jīng)挽救了數(shù)百人的生命。市長(zhǎng)環(huán)保辦公室主任馬克?錢伯斯稱，這只是紐約空氣質(zhì)量戰(zhàn)略的一個(gè)部分，該市的戰(zhàn)略目標(biāo)是與2005年相比，2050年前將溫室氣體排放水平削減80%。

洛杉磯：終于可以看到洛杉磯的山脈了！

Los Angeles, the city where American car culture reached its zenith, has also pushed hard to clean up its air.
洛杉磯是美國(guó)汽車文化最發(fā)達(dá)的城市，該市也在努力凈化空氣。

"We've made incredible progress, we can see the mountains in Los Angeles, when those of us who grew up here never could when we were young," says Joe Lyou, president of California's Coalition for Clean Air.
加利福尼亞清潔空氣聯(lián)盟主席Joe Lyou稱，“我們已經(jīng)取得了驚人的進(jìn)步，我們可以看到洛杉磯的山脈，對(duì)于在洛杉磯長(zhǎng)大的我們來(lái)說(shuō)，在我們小時(shí)候這是絕對(duì)不可能的。”

The dramatic improvement is the result of the most stringent air quality regulation in America. A statewide crackdown on dirty diesel lorries and a push to expand use of zero-emission vehicles are also a big part of the story.
這一巨大的改進(jìn)是美國(guó)最嚴(yán)空氣質(zhì)量監(jiān)管帶來(lái)的結(jié)果。另外一個(gè)重要原因是在全國(guó)范圍內(nèi)強(qiáng)制取締不清潔的柴油卡車以及擴(kuò)大零排放車輛的使用。

In addition to the decades of regulation that have made American cars 99% cleaner than they were 40 years ago, cities like New York and LA have benefitted from American motorists' distaste for diesel, which accounts for only about 2% of cars in the US.
數(shù)十年的監(jiān)管讓美國(guó)的車輛比40年前清潔程度提升了99%，此外，紐約、洛杉磯等城市還因?yàn)闄C(jī)動(dòng)車駕駛者不喜歡柴油而受益，使用柴油的機(jī)動(dòng)車的數(shù)量大約只占美國(guó)車輛的2%。

北京：車輛限行，投資可再生能源

Beijing has used license plate restrictions to limit the number of cars and set out plans to keep the oldest and most polluting vehicles off roads when air is especially bad. More importantly, the government has harnessed public anger over pollution to plough billions of dollars into wind and solar power, becoming the world's biggest investor in renewable energy. Officials have even begun cancelling plans for new coal-fired power stations - a move with repercussions for the health of those living in Chinese cities, and for the planet.
北京通過(guò)車牌限制來(lái)限定汽車數(shù)量，并在空氣特別糟糕的時(shí)候制定計(jì)劃限制最古老和污染最嚴(yán)重的車輛上路。更重要的是，由于公眾對(duì)污染的憤怒，中國(guó)政府已經(jīng)將數(shù)十億美元用于風(fēng)能和太陽(yáng)能建設(shè)，成為世界上最大的可再生能源投資國(guó)。政府官員甚至開(kāi)始取消新建燃煤電站的計(jì)劃，這會(huì)對(duì)中國(guó)和世界人民的健康帶來(lái)影響。

德里：學(xué)校停課，關(guān)閉電廠

Last month, Delhi's 20 million people suffered through the worst smog episode in 17 years, according to the Centre for Science and Environment. Officials temporarily shuttered a coal-fired power plant, halted all construction and demolition work and shut down many diesel power generators.
根據(jù)科學(xué)與環(huán)境中心的數(shù)據(jù)，上個(gè)月，德里市的2000萬(wàn)居民經(jīng)歷了17年來(lái)最嚴(yán)重的霧霾事件。政府官員暫時(shí)關(guān)閉了一家燃煤電廠，停止所有建設(shè)和拆除工作，并關(guān)掉了許多柴油發(fā)電機(jī)。

In a sign that Delhi has begun to acknowledge the problem, officials also closed 1,800 schools for three days, as particulate levels soared to 28 times the recommended maximums.
德里已經(jīng)開(kāi)始認(rèn)識(shí)到空氣污染問(wèn)題的跡象是，因?yàn)轭w粒物質(zhì)的水平飆升至推薦最大值的28倍，政府還讓1800所學(xué)校關(guān)閉三天。
