What should be the approach to deal with local health impacts of cooking fuels that would also inform India's national and global policy?
Author: Sunita Narain
Chulhas – cookstoves of poor women who collect sticks, twigs and leaves to cook meals – are today at the centre of failing international action. Women are breathing toxic emissions from stoves and these emissions are also adding to the climate change burden of the world. The 2010 Global Burden of Disease Report established that indoor air pollution from cookstoves is a primary cause of disease and death in South Asia. As many as 1.04 million pre-mature deaths and 31.4 million disability adjusted life years (DALYs) – measure of years lost due to ill-health, disability or early death – are related to exposure to biomass burning in poorly ventilated homes.

Household air pollutants are responsible for the death of more than 4.3 million people in 2012; more than 50 per cent of them were women and children. These were few of the factors highlighted at the ongoing Anil Agarwal Dialogue where experts discussed health challenges posed by indoor pollution. The two-day Dialogue is being organised by Delhi-based Centre for Science and Environment (CSE).

The campaign to encourage the use of cook stoves for cooking faces many challenges, funds and quality being the two main problems. This was observed by Anurag Bhatnagar, head of Grassroots Trading Network for Women promoted by Self Employed Women’s Association (SEWA).
India is world's second largest producer of bricks, but the environmental cost of producing cheap bricks is huge
Author: Nivit Kumar Yadav
Countries of the South have a massive “under-construction” agenda – as much as 70 per cent of India, for instance, is yet to be built. Vast quantities of material are going to be needed to build homes, offices and factories. The chief building material thus far has been bricks. The standard practice is to dig clay and mud from fields, make it into bricks, and then fire them in inefficient furnaces using a variety of fuels. Brick kilns operate across the world – from China to Peru – and burn anything that is cheap and available to fire.
Centre for Science and Environment’s (CSE) 2015 paper reviewing practices across the world finds that brick kilns are estimated to consume 110 million tonne of coal in Asia – with China using 50 million tonne. Kilns have huge variations in efficiency and it could take anything between 11 to 70 tonne of coal to fire 100,000 bricks.
India employs double the number of labourers than China, yet produces one-fifth of China’s annual brick production of 1 trillion
Author: Jitendra
At least 10 million labourers in India are employed in the unorganised brick kiln industry, working under unhygienic conditions. China’s brick kiln industry, on the other hand, is more organised and less labour-intensive, says
a research paper published by the Delhi-based environment think tank, Centre for Science and Environment (CSE).
Contribute 10% to the total air pollution in south Delhi, 11% in Patna, 30% in Dhaka
Author: Jitendra
A study claims that brick kilns near south Delhi contribute around 10 per cent of the total air pollution in the area. The fuels used in the brick kilns—agri-wastes, powder coals and used tyres—can also be linked to 15 per cent of the total premature deaths due to air pollution in the area.
Sarath Kumar Guttikunda, founder-director of Goa-based non-profit Urban Emission, presented the study at the annual conference of the Centre for Science and Environment. The three-day event, themed “The poor in climate change”, started in Delhi on March 11.
65 per cent of bricks produced in India are manufactured in the Gangetic plains, which have one of the world’s most fertile alluvial plains

Unorganised brick kiln industries are not just emitting black carbon and polluting the air, they are also destroying the fertile top soil.
According to a research paper released by the Centre for Science and Environment on March 11at the Anil Agarwal Dialogue in Delhi, India is the second largest producer of bricks in the world and manufactures nearly 200 billion bricks a year. The paper states that 65 per cent of these bricks are produced in the Indo-Gangetic plains, which have one of the world’s most fertile alluvial plains.

The Euro V emissions standard, notified in 2009, may have been a mistake, experts said at the Anil Agarwal Dialogue 2015, an annual event organised by Delhi-based non-profit, Centre for Science and Environment.
Ray Minjares, who led the programme on Clean Air for International Council of Clean Transportation (ICCT), an international think tank, said that European emission standards had failed to take real-world emissions into account.
Black carbon has claimed 1.15 million lives across the world
Author: Anupam Chakravartty
Unlike carbon dioxide and other greenhouse gases that remain in the atmosphere for years, black carbon takes roughly 10 days to be cleaned out from the atmosphere. Despite its short life span, black carbon has claimed 1.15 million lives worldwide. This was observed by experts at the plenary session of the Anil Agarwal Dialogue (AAD) for 2015, an annual event of the Centre for Science and Environment in memory of its founder, Anil Agarwal. AAD 2015 focuses on short-lived climate pollutants under the theme, 'the poor in climate change'.
CO2 mitigation has to be conjoined with methane and black carbon mitigation to keep temperature rise below 2°C
Author: Sunita Narain, Chandra Bhushan & Anumita Roychowdhury
The world is clearly slipping on its targets to reign in heat-trapping carbon dioxide (CO2) emissions. Action on cutting carbon dioxide emissions is not easy as the world has to re-invent growth as it knows it today to reduce emissions, and it has to share that growth between nations.
In the past few years, attention has turned to the basket of gases known as ‘short-lived climate pollutants’ – which unlike carbon dioxide have a much shorter life in the atmosphere. Out of these, the UN’s Intergovernmental Panel on Climate Change (IPCC) had long recognised methane, nitrous oxide and hydrofluorocarbons as greenhouse gases. In the mid-2000s, another candidate emerged, black carbon – the dark core of particulate matter, which is a product of incomplete combustion and already a deadly local pollutant, contributing to high health burden.
Comparing global warming potential of CO2 and black carbon has its limitations
The understanding about black carbon has come a long way since the nebulous beginning in the seventies, when all the world understood was suspended particulate matter (SPM) – a local pollutant from incomplete combustion, indicted for pollution from fires and vehicles.
It is now understood that black carbon comes from all combustion processes, all dust generating activities, secondary particulates – nitrates and sulfate, and the condensation of gases into liquid droplets. Black carbon is largely a product of low temperature combustion of carbonaceous fuels, and incomplete combustion. The composition of black carbon varies by the type of fuel used, the combustion process, and emission control technologies or practices. Black carbon particles vary in size and can be much smaller than PM2.5 and as small as PM0.1. These last up to minutes, hours and one week or little more in the atmosphere depending on the combustion process and size.
It is known to alter melt cycle of glaciers and interfere with rainfall patterns
Black carbon and snowmelt: Black carbon can also accelerate ice-melt when they settle on snow. The bright snow surfaces reflect a high amount of solar energy back into space. But black carbon absorbs substantial fraction of this energy and re-emit it as heat. The Arctic and the Himalayas are therefore vulnerable. Black carbon on glacial snow is a concern as it alters the melt cycle of glaciers in regions that rely on glacial melt to balance water supply through seasons. These impacts are highly regional depending on the local profile and trend of pollution and transport of pollution. There is now considerable focus on the Arctic and alpine glacier regions and the Himalayan glaciers.
Focus on black carbon may lead to developed nations shifting burden of tackling climate change to the less affluent
There are concerns that focus on black carbon can change the geo politics of climate mitigation responsibility. Developing countries still trapped in poorer technologies that burn fuels inefficiently may be blamed for climate impacts and pushed for tougher climate action. There are apprehensions that the new science can be misused. The developed nations that are the biggest emitters of CO2 and under the common but differentiated principle have the larger responsibility for early action to allow developing countries to improve energy access and grow, may delay action on CO2 mitigation. The UNEP Integrated Assessment Report of 2012 shows that Northeast Asia, Southeast Asia and the Pacific account for the largest share of global black carbon emissions. China accounts for 60-80 percent of the emissions in the region. North America and Europe account for second largest share.
