This Is How Many Years Air Pollution Will Cut From Your Life Expectancy in India – India Real Time – WSJ

Living in India’s capital city New Delhi could shorten your life by six years because of the intensity of the air pollution there, a new report says.

Inhaling tiny air pollutants reduces the life expectancy of Indians by an average of 3.4 years, with Delhi residents losing 6.3 years, the most of all states, according to a new study by the Indian Institute of Tropical Meteorology.

Those living in West Bengal and Bihar, which have high levels of air pollution, face a reduction in life expectancy of 6.1 years and 5.7 years respectively.

The study, which used data from the latest population census of 2011, found that exposure to particulate matter 2.5 results in 570,000 premature deaths each year with an additional 12,000 caused by exposure to ozone.PM 2.5 is tiny particulate matter that is smaller than 2.5 micrometers in diameter. The air pollutants, originating from dust, soot and smoke, can penetrate deep into the lungs, increasing the risk of heart and lung diseases.

India and China Have Most Deaths From Pollution – China Real Time Report – WSJ

More than half of the 5.5 million deaths related to air pollution in 2013 happened in India and China, according to a new study.

About 1.4 million people in the South Asian nation and 1.6 million in its northern neighbor died of illnesses related to air pollution in 2013, researchers at the University of British Columbia in Canada said.

The Indian and Chinese fatalities accounted for 55% of such deaths worldwide, the study said.

Researchers studied risk factors for death and disease around the world and found that air pollution, both indoors and outdoors, was one of the leading contributors to global fatalities.

The inhalation of emissions from power plants, vehicles, the burning of crop stubble before replanting, and wood or open fires in homes are some of the leading causes of deaths from air pollution, the report said.

The number of premature deaths linked to air pollution worldwide will increase over the next two decades unless more aggressive targets are set to curb it, researchers studying India and China’s air said at a meeting Friday in Washington D.C.

A major contributor of poor air quality in India is linked to the burning of wood and cow dung for cooking and keeping warm, particularly in the winter months. These methods are popular among India’s rural and urban poor, who don’t have access to electricity or cleaner fuels.

Household air pollution from cooking with wood “is primarily a problem in rural areas of developing countries of the world,” said Michael Brauer, a professor at the University of British Columbia’s School of Population and Public Health, in Canada.

Over the past few months, levels of tiny insidious particles, known as PM 2.5, in the Indian capital New Delhi have often exceeded amounts deemed safe by the United Nations World Health Organization.

Taking their lead from Beijing, Indian authorities in January experimented with restricting cars on roads for two weeks in New Delhi to reduce emission levels. Delhi Chief Minister Arvind Kejriwal said Thursday the city would revive the restrictions for 15 days, starting April 15.

Scientists said vehicle emissions contribute only 20% to 40% of pollution in Delhi, saying other sources of the particulate matter include the burning of dung, rubbish and leaves and the use of diesel backup generators, which kick in when Delhi’s patchy electricity supply cuts out, as well as emissions from small-scale industries such as brick kilns.

A federal environmental court in New Delhi said Feb. 4 it wanted officials to improve air quality by asking authorities to reduce the number of traditional cremations that use wood to burn bodies, a widespread practice in majority Hindu India.

In China, outdoor air pollution from burning coal was found to be the biggest contributor to poor air quality, causing an estimated 366,000 deaths in the country in 2013. Scientists predict 1.3 million premature deaths will take place in China by 2030 if coal combustion remains unchecked.

“One of the unique things about air pollution is you cannot run, you cannot hide from it. We know that if you improve air quality everybody benefits, so from a health perspective reducing levels of air pollution is actually an incredibly efficient way to improve the health of the entire population,” Mr. Brauer said.

Why Delhi Doesn’t Have a Beijing-Style Response to Pollution – China Real Time Report – WSJ

The cities of Delhi and Beijing share a dubious honor as the world’s most-polluted capitals. But their response to dangerous levels of air pollution separates them.

Earlier this week, Beijing for the first time issued a red-alert for pollution, triggered when authorities forecast air-quality levels above 300 for at least three consecutive days.

On China’s government index, a measure of overall air quality, the maximum reading of 500, is described by the government as “severely polluted.” The Chinese administration immediately sent cars off the roads, shut factories and urged schools to close.

In Delhi, where air was similarly dirty, life went on as normal. The starkly different responses prompted some in the Indian capital to question why their government wasn’t taking Beijing-style measures to combat the smog. For sure, plans are underway in India to tackle the capital’s filthy air.

On Friday, Delhi’s government announced it would impose restrictions on the number of cars on its roads from Jan.1. Residents in the Indian city can look up air-pollution data on the website of The System of Air Quality and Weather Forecasting and Research, known as Safar, which uses data collected at 10 locations in the city. On that index, air quality in the city regularly hits “very poor” conditions when levels of PM 2.5 — insidious particles in the air including dirt, soot, smoke and liquid droplets — spike.

These tiny particles are thought to be particularly dangerous because they can lodge deeply in the lungs and cause inflammation, infection and lead to diseases including cancer. Readings on the Safar monitor are calibrated from “good” to “severe.” The Delhi Pollution Control Committee also publishes raw pollution data but doesn’t give qualitative readings alongside.

The U.S. Embassy, which measures pollution on monitors at its compound in the capital and around the country, warns the very young and elderly to remain indoors whenever air quality becomes what it calls hazardous. But none of the readings currently trigger alerts, or responsive action, by Delhi’s government. That’s because India is a democracy, said Ashwani Kumar, chairman of the Delhi Pollution Control Committee, an arm of the state government.

China, of course, is a one-party state. The idea that alerts should tell people to stay indoors when smog hits was  “absurd,” Mr. Kumar added, and people “should decide for themselves what to do with the pollution information.” However, he said the Delhi Pollution Control Committee does plan to introduce an app so that information is available to residents with smartphones. Less than 10% of Indians own a smartphone. It also proposes to install around 70 big screens in strategic locations around the city advising residents what they can do to reduce pollution, Mr. Kumar added. The idea of an environmental alert system is not alien to India.

Raise the green lanterns | The Economist

WHEN world leaders gathered in Paris to discuss cutting planet-heating emissions, a pall of smog hung over Beijing. In parts of the capital levels of fine particulate matter reached 30 times the limit deemed safe.

Though air pollution and climate change are different things, Chinese citydwellers think of them in the same, poisoned breath. The murky skies seemed irreconcilable with the bright intentions promised in France.

Yet a marked change has taken place in China’s official thinking. Where once China viewed international climate talks as a conspiracy to constrain its economy, it now sees a global agreement as helpful to its own development.

China accounts for two-thirds of the world’s increase in the carbon dioxide emitted since 2000. It has come a long way in recognising the problem. When China first joined international climate talks, the environment was just a minor branch of foreign policy. The ministry for environmental protection had no policymaking powers until 2008. Only in 2012 did public pressure force cities to publish air-pollution data.

Yet today China pledges to cap carbon emissions by 2030 (reversing its former position that, as a developing power, it should not be bound to an absolute reduction); and it says it will cut its carbon intensity (that is, emissions per unit of GDP) by a fifth, as well as increase by the same amount the electricity generated from sources other than fossil fuels. The latest five-year plan, a blueprint for the Communist Party’s intentions that was unveiled last month, contains clear policy prescriptions for making economic development more environmentally friendly.

There’s more

Right after the Paris summit, however it ends, China is expected to make more promises in a new document, co-written by international experts, that presents a far-reaching programme of how China should clean up its act. It is based on models that account for both economic and political viability. On top of existing plans, such as launching a national emissions-trading scheme in 2017, the government may even outline proposals for a carbon tax, something that has eluded many prosperous countries in the West.

The big question is why China is now so serious about climate change. The answer is not that Communist leaders are newly converted econuts. Rather, they want to use environmental concerns to rally domestic support for difficult reforms that would sustain growth in the coming decades. Since a global slowdown in 2008 it has become clear that to continue growing, China must move its economy away from construction and energy-intensive industry towards services. At the same time, China faces an energy crunch. For instance, in recent years China has been a net importer of coal, which generates two-thirds of China’s electricity. It all argues for growth plans that involve less carbon.

This is where signing international accords, such as the one hoped for in Paris, come in, for they will help the government fight entrenched interests at home. Observers see a parallel with China’s joining the World Trade Organisation in 2001. It allowed leaders to push through internal economic reform against fierce domestic opposition. In the same way, a global climate treaty should help it take tough measures for restructuring the economy.

It will not be easy. Provincial party bosses and state-owned enterprises hate to shut factories, particularly in those parts of the country, such as Shanxi and Inner Mongolia in the north, where coal is a big employer. Cutting demand for energy is even harder. Even if the amount of electricity used by state industry falls, that used by private firms and households is bound to increase. What is more, environmental regulations and laws laid down by the centre are routinely flouted.

But cleaning up China’s act has, for the central government, become a political necessity too. Environmental issues have been major public concerns for over a decade, says Anthony Saich of Harvard University, which has conducted polls. True, rural people fret most (and with good reason) about water pollution. But those in the cities gripe about their toxic air. Both represent a reproach to the government over its neglect of people’s lives and health.

That is why national economic goals, political goals, public opinion and international pressure all point towards trying to cut emissions, pollutants included. In particular, says Zhang Zhongxiang of Tianjin University, now that dealing with climate change is a pillar of China’s diplomacy, the government must show it can keep its promises. It has some tools at its disposal. Across the country, the environmental record of government officials has become a crucial part of their evaluation by the Communist Party; and cadres will be held account

India will set Climate Change conference agenda: Modi – The Hindu

Prime Minister Narendra Modi has slammed developed nations for questioning India over global warming despite it having the lowest per capita emission of gases and asserted that India will set the agenda for the Climate Change conference to be held in France in September.

Siemens CEO Joe Kaeser (centre) smiles as a trainee hands over a small Berlin TV Tower to the Prime Minister Narendra Modi during a visit to the Siemens company in Berlin on Monday.

“I am surprised that the world is scolding us even though our per capita gas emission is the lowest…,” he said while addressing a reception for the Indian community here last night.

Underlining that preservation of nature was in the customs and tradition of Indians which they have done for ages, Mr. Modi said, “The whole world is posing questions to us. Those who have destroyed climate are asking questions to us. If anybody has served the nature, it is Indians.”

He asserted that India is “not answerable to the world” and will tell them that “you destroyed nature.”

Underlining that India should lead the way to deal with climate change, the Prime Minister said, “India will set the agenda for the upcoming Conference of Parties (COP)” meeting to be held in Paris in September.

Referring to India’s traditional practices and traditions, Mr. Modi said it is the only country which has served the nature the most as Indians even treat even river as mother and worship trees.

“Treating the nature well comes naturally for Indians and they (developed nations) are teaching us,” he said.

The Prime Minster said the solutions to the “crisis” on account of global warming are in India’s traditions and customs.

“We should go out with confidence,” he said, asking the Indian diaspora to contribute in this regard.

At the same time, he said India also wants solutions to the global problem of climate change. In this regard, he spoke about his government’s initiatives to tap clean and renewable energy for generating 175 Gigawatts of electricity from it.

One Gigawatt is equal to 1,000 MW.

“Earlier, we did not go beyond Megawatts but in 10 months, we have at least started thinking of Gigawatts,” he said.

India launches air quality index to give pollution information – BBC News

India has launched its first air quality index, to provide real time information about pollution levels.

The index, announced by Prime Minister Narendra Modi, will initially monitor air quality in 10 cities.

Last year the Environmental Preference Index ranked India 174 out of 178 countries for air quality.

The rising and health-endangering pollution has been mainly blamed on a huge increase in vehicles, particularly diesel-driven cars, on Indian roads.

Polluting industries, open burning of refuse and leaves, massive quantities of construction waste and substantial loss of forests have also led to high pollution levels in cities.

A World Health Organization (WHO) survey last year found that 13 of the most polluted 20 cities in the world were in India. The capital, Delhi, was the most polluted city in the world, the survey said.

It is a leading cause of premature death in India, with about 620,000 people dying every year from pollution-related diseases, says the WHO.

On Monday, Mr Modi said India “has to take the lead in guiding the world on thinking of ways to combat climate change”.
