A study conducted by the School of Energy, Madurai Kamaraj University, found that household appliances also contribute to greenhouses gases, and indoor plants can help to tackle the problem, say ex

Pollution is the largest environmental cause of disease and premature death in the world today. Diseases caused by pollution were responsible for an estimated 9 million premature deaths in 2015—16% of all deaths worldwide— three times more deaths than from AIDS, tuberculosis, and malaria combined and 15 times more than from all wars and other forms of violence. In the most severely affected countries, pollution-related disease is responsible for more than one death in four.

KOLKATA: The air that you inhale inside the warmth of your home could be as poisonous or even worse than the outdoor air, warns a study conducted by a group of city environmentalists and the Calcut

The national government wants counties to allocate at least Sh100 million ($969,929) annually for renewable energy projects in their County Integrated Development Plans in order to reduce indoor ai

For households without access to grid-based electricity or gas for cooking, traditional cook stoves are typically fuelled by wood or charcoal, generating considerable indoor air pollution. Cook stoves fuelled with biogas provide complete combustion, significantly alleviating health and environmental problems.

Air pollution exposure is the second most important risk factor for ill health in South Asia, contributing to between 13% and 21.7% of all deaths and approximately 58 million disability adjusted life years (DALYs) through chronic and acute respiratory and cardiovascular illnesses.1 Of the top 30 cities in the world with the poorest air quality in 2016, 17 are in South Asia.2 The impact of air pollution transcends boundaries. The “brown cloud”—caused by pollution from carbon aerosols—is a phenomenon captured in satellite images of atmospheric haze over South Asia, as well as China.

The 2015 smoke haze episode was one of the most severe and prolonged transboundary air pollution events ever seen in Southeast Asia (SEA), affecting the air quality of several countries within the region including Indonesia, Malaysia and Singapore. The 24 h mean outdoor PM2.5 (particulate matter (PM) with aerodynamic diameter ≤ 2.5 μm) concentrations ranged from 72–157 μg m−3 in Singapore during this episode, exceeding the WHO 24 h mean PM2.5 guidelines (25 μg m−3) several times over.

As pollution levels deteriorate in the National Capital Region, health experts have warned that continuous exposure to polluted air has the potential to cause a stroke among adults.

Indoor air pollution is second only to outdoor air pollution when it comes to deaths caused globally, a recent survey found.
