The Clean Development Mechanism (CDM) under the Kyoto Protocol to United Nations Framework Convention on Climate Change (UNFCCC) provides an opportunity for the Indian power sector to earn revenue through the reduction of greenhouse gas emissions (GHG), particularly carbon dioxide (CO2). India has tremendous potential for CDM projects. Power generation …
Atmospheric aerosols (a mixture of solid or liquid particles suspended in the air medium) are short-lived, with a residence time of about a week in the lower troposphere. Unlike the principal greenhouse gases, aerosols are more concentrated in the source regions and exhibit strong spatial and temporal variations.
With their focus on greenhouse gases, atmospheric scientists have largely overlooked lowly soot particles. But black carbon is now a hot topic among researchers and politicians. Jeff Tollefson investigates.
Austria is considered a European leader in the use of solid biomass for heat and power generation. But a new environmental policy could jeopardize the success of the past few years.
Biomass based power generation is one of the promising renewable options. This article reviews the status and potential of biomass based power for India.
Biofuels for transport, including ethanol, biodiesel, and several other liquid and gaseous fuels, have the potential to displace a substantial amount of petroleum around the world over the next few decades, and a clear trend in that direction has begun. This report looks both at recent trends and at the …

State Science and Technology Minister Joy Gobinda Debroy told UNI here today that the ministry will support …
Vishal Sharma / Agra October 27, 2008, 0:12 IST Gasifier plant to cut fuel bills by Rs 8 lakh a year; currently on subsidy. Worried over the rising prices of liquiefied petroleum gas (LPG) and the unavailability of natural gas, some enterprising industrialists of Agra have come up with an …
Rice is the most important Kharif crop of Punjab. With the increase in production of rice there is concomitant increase in the production of residue (rice straw), which is approximately 18.75 MT. About 80 percent of the rice residue it burnt in the fields, particularly after harvesting rice by combine …
Residue burning practice is followed in major Indian states of Uttar Pradesh and Punjab. Agricultural residue burning in the fields and used otherwise for rural domestic needs is responsible for a large number of toxic emissions, which are a health hazard. The main pollutants contributed from biomass burning are aerosols …
Tobacco smoking, passive smoking, and indoor air pollution from biomass fuels have been implicated as risk factors for tuberculosis (TB) infection, disease, and death. Tobacco smoking and indoor air pollution are persistent or growing exposures in regions where TB poses a major health risk. The researchers undertook a systematic review …
The burning of biomass fuels results in exposure to high levels of indoor air pollution, with consequent health effects. Possible interventions to reduce the exposure include changing cooking practices and introduction of smoke-free stoves supported by health education. Social, cultural and financial constraints are major challenges to implementation and success …
Majority of rural households in India use only kerosene for lighting. Most of the lamps are hurricane-type, which produce very poor light intensity of about 60
The dismal situation and poor quality of life in rural India is because of unavailability of energy. It is shown that sophisticated technology can help solve this and other problems of rural areas. A call is made to the global technological community to help provide such technologies. Finally issues of …
The paper brings out detailed account of an intervention through a gasifier system as an alternative to reduce the fuel cost in the silk dyeing industry. The field performance of a gasifier based silk dyeing oven developed by The Energy and Resources Institute (TERI) is described in detail.
This paper estimates the economic burden of respiratory illness in rural UP (Uttar Pradesh), a state in North India. This is based on a large comprehensive survey covering a sample of 7564 households in 6 districts and 51 villages in UP. The economic value of the days lost due to …
Anthropogenic activities are responsible for the enhanced emission of reactive nitrogenous species like nitrous oxide (N2O), oxides of nitrogen (NOx) and ammonia (NH3) into the atmosphere from the biosphere. This article reviews the available estimates of emissions of these reactive nitrogenous species for India.
until now, it was believed that methane, from cattle dung and paddy cultivation, was the second biggest contributor to global warming after carbon dioxide. A recent review says soot is the second biggest contributor. Soot has 60 per cent of the effect of carbon dioxide on global warming, and China …
