India "Green" with Heavy Pollution

An interesting piece from the Canada Free Press..

The National Geographic Society ranks India as the world’s ‘greenest’ society. How did India achieve this? The Times of India explains the National Geographic Society’s logic. “That cold water bath that many Indians have because there’s no electricity…that ‘matka’ they use because they can’t afford a fridge…and the long walk they take to work and back because private transport is expensive and public transport shoddy. There’s an upside to the hard life. Indians may be green with envy at the consumption-driven lifestyle in the West, but their own frugal ways and modest means have catapulted them to the top spot in the world’s green index, making them the most environmental-friendly denizens of Planet Earth.” (1)

Reports Todd Myers, “The very squalor that served as a warning to Paul Ehrlich forty years prior (The Population Bomb, where he said that India couldn’t possibly feed 200 million people by 1980) is now presented as evidence the Indian people (now over a billion population) are, in fact, living in harmony with the planet. Exhibit A for planetary destruction in 1968 turned state’s evidence in 2009, arguing that others should follow India’s lead for the sake of Mother Earth.” (2)

The National Geographic Society ranks countries based on how much beef people eat, the number of cars they drive, the type of energy they use for home heating, and the like. For each of these categories the National Geographic Society cites scientific evidence of the relative impact on the planet. (3) That rating system, however, should lead them to conclude that the India of 1968 was even greener yet, with fewer people eating beef, driving cars and using fossil-based energy, or using any energy at all for that matter.(2)

Todd Myers adds, “The National Geographic Society’s focus on resource use has negative consequences because it sends the wrong signals about how to make real improvements in environmental quality. Calling India the greenest country in the world does not alter the fact that in some of the most tangible and important measures of environmental quality, the subcontinent fares quite badly.” (2)

Some Examples:

A 2007 study by a prominent cancer institute found, “Some 70% of people in the city of Calcutta suffer from respiratory disorders caused by air pollution.” Worse, in 2009 New Delhi was determined by some estimates to have the worst air quality in the world. That isn’t the end of the problems for New Delhi residents—the water in the Yamuna River is so polluted that levels of fecal coliform are ‘100,000 times the safe limit for bathing.’ Knowing that they live in the ‘greenest’ country is probably little comfort to Indians dealing with these health threats. (4)

India is growing rapidly and its major cities experience particulate levels often eight to ten times higher than the worst American cities. India is the fourth-most coal dependent country in the world and has enough reserves to last for the next 100 years. India’s coal consumption has been increasing at 6 percent per year since 2000 and its net coal imports in 2009 were 74,000 short tons, about two-thirds of China’s level. (5)

Carbon emissions in India are rising faster than nearly every other country on the planet. Between 1980 and 2006, India’s carbon output increased by 341%, compared to 321% for China, 103% for Brazil, 238% for Indonesia and 272% for Pakistan. (6)

Two cities in India made The Blacksmith Institute’s 2011 report on the ten most polluted cities: Number 3-Sukinda, India- waste rock and untreated water from local mines seep into local water supplies. The air and soils are also heavily polluted, and; Number 4-Vapi, India-more than 50 industrial places discharge heavy metals, pesticides, and chemical waste. Mercury in the groundwater is 96 times higher than World Health Organization standards. Very high incidences of cancer and birth complications have resulted. (7)

Believe it or not! Far more people in India have access to a cell phone than to a toilet and improved sanitation, according to UN experts. Roughly 366 million people (31 percent of the population) had access to improved sanitation in 2008. Meanwhile 545 million cell phones were connected to service in India’s emerging economy. Says Zafar Adeel of the Institute for Water, Environment and Health, “It is a tragic irony to think that in India, a country now wealthy enough that about half of the people own phones, about half cannot afford the basic necessity and dignity of a toilet.” (8)

So, there you have it. If you want to be the ‘greenest’ country in the world be prepared to do without decent sanitation and be willing to live in cities with massive air pollution and squalor.

Todd Myers sums this up quite well, “When it comes to air quality, there simply is no comparison between India and the United States. Ignoring this reality should lead us to question the value of the National Geographic’s ranking system. Their index is more measurement of which countries fit their preconceived notion of green rather than an objective test of how the environment is actually faring. Add this to income and life expectancy disparities between India and the United States, and National Geographic ends up giving the ‘green’ lifestyle a pretty bad name.” (2)

Air Pollution Sources in Pune, India

A recent study has shown that brick kilns, stone quarries and diesel generators contribute to a city's pollution level in a major way. Even though kilns and quarries are located on the outskirts, the pollution travels towards the city. Article published in Times of India (Pune) on December 29th, 2011

The study 'Urban air pollution and co-benefits analysis in India' was carried out in six cities, including Pune, in 2011. Conducted by New Delhi-based independent research group UrbanEmission.Info, the aim of the study was to better understand sources of air pollution.

In case of pollutant particulate matter PM 10 (10 micrometre or less in size) in the city, it was found that around 47% of PM 10 is contributed from road dust, nearly 17% from vehicles, close to 13% each from brick kilns and rural bio-mass cooking/ kerosene use and almost 7% from generators and industry. In case of PM 10, all six cities exceed the annual ambient standard of 60 ug/ m3 (micrograms per cubic metre).
The study was initiated with support from the Climate Works Foundation (USA) and the Shakti Sustainable Energy Foundation (New Delhi). The research group used the SIM-Air (Simple Interactive Models for better Air quality) family of tools for the study. The tools help establish a multi-pollutant emissions inventory and involve rapid assessment.

Sarath Guttikunda, founder of UrbanEmissions.Info and developer of the SIM-Air family of tools, who was in the city recently to deliver a talk organised by the Pune Municipal Corporation (PMC), said that a majority of the 400 brick kilns located in the Pimpri-Chinchwad Municipal Corporation (PCMC) areas add to the pollution level in Pune city and that the central parts of Pune city are the most polluted. There is use of light- and heavy-duty vehicles in and around the brick kilns too adds to pollution.

"Diesel generators sets used in hotel, apartments, hospitals and markets is a new source contributing to pollution. Diesel generator sets are a common sight in most parts of the six cities and are a significant source of pollutant emissions and green house gas emissions,'' he said.

Guttikunda, who is also an affiliate associate research professor at the Desert Research Institute, Reno, USA, pointed out that the pollution from fossil and bio-mass fuel usage at brick kilns is a growing problem in most cities. Burning of fossil and biomass fuels releases significant amounts of sulphur dioxide, nitrogen oxide and particulate matter. These emissions have an immediate affect on the ambient air and human health.

In Pune, most of the brick baking is conducted as a pile with no chimney to support to movement of the burning emissions, whereas in Chennai, the same process is supported with a chimney, which allows for release of emissions at a higher altitude, the study states.

Besides the brick kilns, stone quarries are a common sight in these cities. At one stone quarry area in Pune, it was observed that on a daily basis around 500 truckloads of stone, black boulders and murum are extracted and transported to various parts of the district and the state. The health risks associated with constant exposure to the dust particles in these areas is under study. Also, quarry locations account for the re-suspension of dust due to crushing and handling of rock and emissions from the truck movement and use of diesel generators, he said.

The study with recommendation for the city is now submitted to the PMC. PMC's environment officer Mangesh Dighe said he has received the study and will now look into the recommendations as well as the model.

Flight Cancellations Due to Air Pollution in Ulaanbaatar

We have heard of flight cancellations in Delhi and similar delays in Beijing, due to air pollution and winter fog. The implications of air pollution are also now observed in Ulaanbaatar, where the flight schedules are no where comparable to those of Delhi or Beijing, but still disrupting.

From Shanghai Daily, December 27th, 2011
Heavy air pollution in Mongolia causes flight delays, cancellations

Heavy air pollution in Mongolia's smog-filled capital has caused flight delays and cancellations in recent days, an Air China official said Tuesday.

During the last week, many flights were disrupted for six days except Thursday. And a total of 13 flights had been delayed or canceled this month due to air pollution, a 160-percent increase compared with the same period of last year, according to statistics provided by Air China.

With temperatures dropping sharply in December, thousands of residents living in ger districts near the airport have begun to burn large quantities of coal and firewood to get warm, and power plants are also operating at full steam to meet high demand for electricity for heating, causing a thick smog around the airport, said the official from Air China's Mongolia Bureau.

"Ulan Bator as well as the airport are located in a basin with mountains surrounded, so the smoke is blocked by the mountains and cannot dissipate. Wind also is very rare during winter time which worsens the air pollution here," the official said.

In recent years, more and more people from rural areas have rushed into the capital seeking better lives, making the city increasingly crowded.

The new residents live in ger districts in the suburbs, and due to the lack of access to central heating systems, they burn coal, firewood and garbage, which causes severe air pollution.

Air pollution kills about 1,600 people in Ulan Bator every year. A report released this month by the World Health Organization showed that the concentration of dust particles in the air was 35 times the standard recommended by the WHO.

Pollution from Brick Kilns and Quarries in Pune, India

This is an article published in Indian Express on December 28th, 2011, based on a study conducted by UrbanEmissions.Info

Mushrooming brick kilns, stone quarries major air polluters in city
by Sushant Kulkarni
Posted online: Wed Dec 28 2011, 02:19 hrs

Pune : Rapidly mushrooming brick kilns and stone quarries along the city boundaries are major contributors to air pollution within the city, reveals a study by a Delhi-based research group which has used data provided by the Pune Municipal Corporation and the Maharashtra Pollution Control Board. The researchers have stressed the need to use better technologies for these activities, instead of just pushing them away from cities.

A Delhi-based research group named did a detailed study of the pollution in six cities including Pune, Chennai, Indore, Ahmedabad, Surat and Rajkot. The studys says the areas around Pimpri-Chinchwad and Hadapsar, where brick kilns are mushrooming, and areas along Nagar Road where there are a large number stone quarries, are major contributors of the suspended particulate matter found within the city.

Sarath Guttikunda, founder and analyst with the group, said, “To study Pune’s pollution, we considered 32X32 km area, which include both Pune and Pimpri-Chinchwad limits. The data collected over four months of summer shows that brick kilns contribute to the 67 per cent of particulate pollution in the Western fringe areas of the city. These brick kilns are major polluters as most of them use coal and wood and sometimes bad quality oil.”

The study found that in the fringe areas of the city an average particulate matter pollution is 68 micro gram per cubic metre and that in the central part it’s around 111 micro gram per cubic meter. “It is very interesting to note that the chemical analysis done by the Central Pollution Control Board and the model developed by us show that brick kiln and stone quarries outside city contribute to about 25 per cent of pollution.” said Guttikunda. Mangesh Dighe, the environment officer with PMC said, “As per the Bhurelal Committee Report we had moved the brick kilns out of the city some years ago. But there is no such rule for stone quarries."

Sources of Air Pollution in Delhi

Delhi’s choking air pollution has caught the attention of politicians and newswires in recent weeks. A massive influx of cars, which are being added at an estimated rate of more than 1,000 a day, is an oft-cited reason for the dirty air. (reported @ NY Times)

But according to data collected by, a research group that studies air pollution across India, cars account for 25 percent or less of two key pollutants, carbon monoxide and the larger particulate matter known as PM10. Another oft-cited source, open fires used by some poorer residents for heating and cooking, accounts for less than 10 percent of the air’s carbon monoxide and PM10.

Other key polluters, Urbanemissions says, are power plants (Delhi relies on several coal-fired plants for much of its electricity), industries and the dozens of brick kilns that ring the city, supplying bricks for Delhi’s numerous construction projects.

Wood Smoke and Uutdoor Air Pollution Costs Lives and Money in US Northwest

From Mr. Lalloobhoy Battliwala

Where There's Smoke, There's Sickness: Wood Smoke now a major Northwest air polluter
by Robert McClure,

Wood Smoke now a major Northwest air polluter.

The warning label on the wrapping of neatly split firewood is one we're more accustomed to seeing on cigarettes or heavy-duty chemicals: "known... to cause cancer, birth defects or reproductive harm."

But in fact, heart attacks, strokes, high blood pressure, asthma attacks and premature death – in addition to cancer – all are linked to wood smoke pollution. It's a finding that poses a vexing dilemma for poor and rural communities around the Northwest where wood is a cheap or even free source of heat.

And in Tacoma, where the air is so dirty it violates the Clean Air Act, authorities are gearing up for what promises to be an arduous and expensive campaign over the better part of a decade to clean up wood smoke pollution. It's an effort that already has some residents chafing at government interference, and one that will set the stage for how other Northwest communities are treated when they bump up against tightened federal pollution standards.

In Tacoma and many towns across the Northwest, wood smoke is a prime culprit in driving spikes of sooty, toxic air pollution that leave some residents – particularly asthmatics, kids and the elderly – gasping for breath. It's especially bad during sunny, cold stretches like those we've seen in recent weeks, because atmospheric conditions trap the pollution close to the ground.

Will Congestion Fees Solve Delhi's Traffic Problems?

Article below from The Guardian quotes, "This will help reduce congestion … [and] encourage people to use public transport".

How much of this is possible with the limited public transport in place? Compare with the public transport system in Singapore and London, Delhi is not close to the required capacity to warrant a shift from cars to bus or metro, by introducing a congestion fees. Toll roads and fuel taxes aside, congestion fees system requires an enormous scale-up in the current public transport system to make it work and see some tangible results in reducing congestion and related air pollution.

(an interesting response from Cornie Huizenga, attached after the article)

Articles on congestion pricing


Delhi Plans Congestion Charge to Ease Gridlock

No one could fault the plan for lack of ambition: to tame the choked streets of India's notoriously chaotic capital by imposing a congestion charge modelled on that in London, Singapore and a handful of other cities.

The Municipal Corporation of Delhi, the authority charged with providing civic services to the city, hopes to introduce a system to levy a 150-rupee (£2) fee on cars, motorbikes and even rickshaws entering central areas during the day.

"This will help reduce congestion … [and] encourage people to use public transport," the head of the authority, KS Mehra, told local press. Lorries will be made to pay a higher fee.

A congestion charge has existed in Singapore since the 1970s and various systems have been successfully introduced in London, Rome, Milan and several Scandinavian cities in recent years.

Authorities in Beijing recently said they were considering congestion charging, and other Chinese cities such as Shanghai and Nangjing are reported to be interested. But no city of the size and complexity of Delhi has attempted to introduce such a scheme.

Few doubt the necessity of radical measures in India's capital. Construction of a metro system and measures to boost the use of buses has barely slowed the increase in traffic in recent years. A decade of rapid economic growth and a broad distaste for public transport among the expanding middle class means there are now 6.8m vehicles on Delhi's roads, at least twice as many as five years ago.

Gridlock is common and, during winter, heavy smog leads to accidents, respiratory diseases and mass flight cancellations.

Other Indian cities such as Mumbai, the country's commercial capital, are considering similar measures. The Delhi scheme would first be implemented in areas around the historical old centre.

But experts are sceptical. "If you look at what is already in place to reduce congestion, such as toll gates around Delhi, they make the problem worse, not better," said Rumi Aijaz, of the city's Centre for Policy Research thinktank. "Even if the proposal is accepted politically, the necessary infrastructure simply isn't there."

The tolls on key roads linking Delhi with satellite cities cause huge traffic jams. Occasionally they are the focus of protests that can turn violent. Aijaz said a broader strategy to tackle traffic in the city was necessary. "There has to be a range of measures to manage the issue. Nothing done in isolation will work," he said.

Experts point out that one serious problem is a lack of proper licensing or law enforcement in Delhi. Driving permits can be bought illegally and laws that should ensure safe driving and a smoother traffic flow are routinely ignored.

Fines for traffic violations can usually be avoided by paying a small bribe to police officers. There are few cameras, although a Facebook page asking irate commuters to post their own photographs of offenders has met with a massive response.

Senior police officers said charging would be a positive step – if technology to avoid queuing was introduced. But even if the practical obstacles can be overcome, the support of the infamously fractious "delhiwalla" – inhabitants of the city – will be hard to win.

Some shopkeepers welcomed the move, but their customers were less enthusiastic. "People are already reeling under taxes … we don't need any more," Mamta Choudhary, a teacher who regularly shops in one of the areas designated for the new scheme, told the Times of India newspaper.

Ram Thakur, a 45-year-old manager who spends up to two hours a day in traffic driving from the satellite city of Faridabad to his office, said no amount of charging would make him give up the small car that he bought a year ago. "I started on a bicycle and I've taken buses for 20 years. Now I am a car owner and life is very much nicer. I am not giving it up to go back on buses or bikes," he told the Guardian.

Dr Robin Hickman, an expert in urban transport at London University, said that implementing a congestion charge in Delhi would be "extremely difficult. "It would probably be a better option to increase tax on fuel in the city and invest the funds generated in public transport," Hickman, who has worked in Delhi, said.

Dear All,

It is interesting to read this. I just am back from the annual UMI meeting on urban transport in Delhi. As far as I know none of the keynote Indian speeches and presentations made reference to this.

I think that the article is significant in the sense that it points at a growing awareness in Asian cities that it will be hard, if not impossible, to revert the current pattern of growing un-sustainability of transport systems, associated with rapidly growing vehicle fleets merely by investing in public transport and promoting NMT.

Increasingly, cities seem to be willing to put in place demand management measures to restrain the growth in number of vehicles and their use. Evidence of this is for example the decision of Beijng and other cities in China to follow the example of Singapore and Shanghai who for more than 10 years have had a vehicle quota system. The economic success of these two cities clearly demonstrates that restraining the number of vehicles does not undermine economic growth.

A quota system can be implemented more easily and it is cheaper to administer. If it is operated on the basis of an auction system it can also generate substantial funding which should be a major contribution towards improving public transport and NMT, except in the case of metro's which are more expensive. In Shanghai, about 100,000 car licenses are auctioned each year resulting in about $ 600 million in income.

The basic underlying premise is of course that road space is not a free commodity and that access to its use by cars can be regulated in the same manner as other parts of the city such as land for construction where public lands are sold/leased or taxed for private development and the proceeds are used for developing schools, hospitals etc.


Revealing the costs of Air Pollution from Industrial Facilities in Europe

From Mr. Lalloobhoy Battliwala

Link to the report after my comments..

On page 18, they say "One data point from the E-PRTR database was corrected prior to analysis as it appeared to have been reported incorrectly by three orders of magnitude when compared to the reported emissions of the other pollutants from the facility. This was the value for SOx emissions from the 'Teplárna Strakonice' plant (facility ID 14301) in the Czech Republic for which the reported estimate of 1 250 000 tonnes of SOx was taken to be 1 250 tonnes."

The same page also has Table 2.1 giving a figure "42 568 284 670" for "Aggregated national total emissions (tonnes)" - presumably for the 30-odd countries covered by the report.

This 42.6 billion tonne CO2 estimate is about 27% higher than the 33.4 billion tons of WORLDWIDE CO2 emissions from fossil fuels in 2010 (Link).

Yes, EEA says they count biomass CO2 as well, but surely these facilities don't burn whole forests down every year.

Looks like EEA is sensitive about some orders of magnitude, not all.

Also, these are not "costs" in the sense of having been expended. They are "imputed" costs. Mostly in terms of health damages, but in the case of CO2, on "marginal abatement costs", which are debatable. In any case, there is very little evidence that CO2 is a health pollutant (except in heavily congested closed rooms).

Excluding CO2, seems like they would impute a cost less than ~$200 per capita per year or less than 1% of GDP. Another way of looking at it is that the actual health expenditures are perhaps in the range of $500-1,500 depending on the country, all diseases and health conditions included, so putting out an imputed cost that is 10-20% of the total health budget is largely an arithmetical exercise.

Read the full press release

Air pollution from the 10,000 largest polluting facilities in Europe cost citizens between € 102 and 169 billion in 2009. This was one of the findings of a new report from the European Environment Agency (EEA) which analysed the costs of harm to health and the environment caused by air pollution. Half of the total damage cost (between € 51 and 85 billion) was caused by just 191 facilities.

Key Findings
  • Air pollution by the facilities covered by EEA’s analysis cost every European citizen approximately € 200-330 on average in 2009.
  • Countries such as Germany, Poland, the United Kingdom, France and Italy, where a high number of large facilities are located, contribute the most to the total damage costs. However, when damage costs are weighted in an attempt to reflect the productivity of national economies, the ordering of countries changes significantly. The emissions from countries such as Bulgaria, Romania, Estonia, Poland and the Czech Republic are then relatively more important with regard to the damage costs.
  • A small number of individual facilities cause the majority of damage costs. Three quarters of the total damage costs were caused by the emissions from just 622 industrial facilities – 6 % of the total number. The facilities with emissions associated with a high damage cost are in most cases some of the largest facilities in Europe which release the greatest amount of pollutants.
  • Carbon dioxide (CO2) emissions contribute the most to the overall damage costs, approximately €63 billion in 2009. Air pollutants, which contribute to acid rain and can cause respiratory problems - sulphur dioxide (SO2), ammonia (NH3), particulate matter (PM10) and nitrogen oxides (NOx) - were found to cause €38-105 billion of damage a year.

WHO on Climate Co-benefits of walking and bicycling

From Mr. Lalloobhoy Battliwala

More for Asia, Africa than Europe?

Good criticism of IPCC review (see p. 4-5), though I suspect the guidelines limit coverage of land use planning issues unless there is new literature.

"“Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” Ok, but how does one deal with disease and infirmity?


WHO Report Shows Health and Climate Co-benefits in Transport Sector

6 December 2011: The World Health Organization (WHO) has launched a report on the health benefits of low-carbon transport measures, such as rapid transit, walking or cycling, as part of its "Health in the Green Economy" series.

Launched at a side event during the Durban Climate Change Conference, the report outlines strategies that can help reduce greenhouse gas (GHG) emissions in the transport sector while generating health benefits.

The report's key messages stress that a combination of active modes of transport, such as walking or cycling, rapid transport and improved land use to improve access to key destinations by these modes, can yield much greater immediate health co-benefits than improving fuel and vehicle efficiencies.

Such health benefits include reduced cardiovascular and respiratory disease from air pollution, less traffic injury and noise-related stress, and prevention of some cancers, type 2 diabetes, heart disease and other obesity-related risks. Meanwhile, the report notes, a shift to fuel efficient diesel engines could increase emissions of health-damaging small particulates.

Recommended strategies include: integrating urban residential and commercial areas through more compact land use; including health and equity costs in cost-benefit analyses of transport projects; and improving active transport, rapid transit and public transport as cost effective measures to mitigate GHG emissions.

The report further stresses that healthier transport strategies also can help close the health equity gap in low- and middle-income countries by: reducing air pollution; providing benefits to women, older adults, children, people with disabilities and lower income groups; reducing the need for biofuels and related threats to food security; and reducing the use of older, more polluting vehicles.

Bicycling for an Aging America

From Mr. Lalloobhoy Battliwala

Two thoughts on bicycles and similar non-motorized transport options:

1. America is greying, and no telling when the grey would return to cities rather than in outer suburbs (or that suburbs with high grey densities would appear). The numbers for people aged 15-54 and 55+ for 1980 were 145 and 52 m; for 2011 are 172 and 91 m; for 2040 will be 190 and 149 m respectively. As % of total population, 57 and 21 in 1980; 53 and 28 in 2011; 46 and 36%.

If you take 15-40 as the bicycling age, 95, 106 and 98 m respectively.

Today's bicyclists (15-40) will be in the 45-70 age group then and 106 m strong in 2040.

An older population can also use bicycles and enjoy the health benefits. Keeping roads safe for them as well, not just the next younger generation, is an important consideration.

Besides, retirees may find gas cars much more expensive as their incomes decline and gas prices go up.

The 45-70 age cyclist group of the future will ride at lower speeds, and may well compete with the younger age for the cycle lanes and parking spaces. Since not all bicycling regulations can be age-separated, the best is to accommodate as much of both groups as possible in the planning and regulatory process.

2. For US locales, where distances are longer, a large market potential lies in electric and hybrid (pedal-battery) scooters and tricycles for the seniors. (Seniors would ride slower but may brake more often, hence a hybrid.)

Introduction to Black Carbon by NOAA


NARRATOR: Black carbon is the fancy name for soot. And like carbon dioxide, it’s causing changes in the Arctic climate.

Black carbon comes from the burning of fossil fuels, like coal and diesel, and from forest fires, and cookstoves. The majority reaching the Arctic comes from North America and Eurasia.

Studies suggest that black carbon is contributing to the acceleration of sea ice melting in the Arctic. Loss of this ice would lead to more rapid warming and possibly irreversible climate change.

Black carbon is dark in color and warms the Earth in two ways: When it’s in the air, the particles absorb sunlight and generate heat in the atmosphere. This can affect cloud formation and rain patterns. When it covers snow and ice, the sun’s radiation is absorbed instead of being reflected back into the atmosphere. This again generates heat and speeds up melting.

It’s like wearing a black shirt on a sunny day. You’re going to feel hot. To stay cooler, you would wear a light-colored shirt that would reflect the sun’s warmth.

Scientists from around the world are studying black carbon from all possible angles. They’re using ships, snowmobiles, weather balloons, as well as manned and unmanned aircraft to collect data.

The instruments on board measure the total numbers of particles in the atmosphere, including the number of soot particles, and chemicals that can identify where the soot comes from. They also measure incoming radiation from the sun and the reflectivity of snow and ice covered surfaces. Newly fallen snow is also analyzed to trace where the black carbon is coming from.

The bad news is that black carbon is contributing to the acceleration of sea ice melting in the Arctic. The good news is that since black carbon is a particle and not a gas, it doesn’t last very long in the atmosphere. This means reducing the amount people produce can have immediate effects on the rate of climate change.

Scientists are hopeful that their research findings from the Arctic will help world leaders develop strategies for change, so that black carbon can no longer leave a dirty footprint on our world.
