The UNEP OzonAction Branch has released a publication to promote south-south cooperation, addressing efforts to phase-out methyl bromide in developing countries, as well as challenges remaining. The publication, 'Phasing-out Methyl Bromide in Developing Countries: A success story and its challenges,' analyzes factors that may affect the continuity of methyl bromide …
This booklet explains EPA's Air Quality Index (AQI) and the health effects of major air pollutants. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. For each of …
Eight Northeastern and mid-Atlantic governors on Monday petitioned the U.S. Environmental Protection Agency to require "upwind" states in the Midwest and South to curb ozone-forming pollution from their power plants, which they say travels downwind and poses health risks to their citizens. They want the EPA to force nine states …
In 2010, the XIX Commonwealth Games (CWG-2010) were held in India for the first time at Delhi and involved 71 commonwealth nations and dependencies with more than 6000 athletes participating in 272 events. This was the largest international multi-sport event to be staged in India and strict emission controls were …
Due to the rapid growth of electricity demand and the absence of regulations, sulfur dioxide (SO2) emissions from coal-fired power plants in India have increased notably in the past decade. In this study, we present the first interannual comparison of SO2 emissions and the satellite SO2 observations from the Ozone …
The project aims at monitoring 10 types of pollutants that affect people's health; it will also work towards reducing concerns. The Indian Institute of Tropical Meteorology (IITM) plans to install 10 air quality monitoring systems and 20 automatic weather stations across Mumbai. These stations will measure pollutants such as suspended …
Slowing the rate of global warming over the near term by cutting short-lived climate pollutants to complement carbon dioxide reductions for the long term. Carbon dioxide (CO2) emissions are responsible for 55-60% of anthropogenic radiative forcing. Fast and aggressive CO2 mitigation is essential to combat the resulting climate change. But …
सिटी का आबोहवा दिवाली पर काफी जहरीली हो जाती है। प्रदूषण डिपार्टमेंट की पिछले साल की रिपोर्ट के अनुसार, दिवाली के दौरान यहां का एयर प्रदूषण करीब 200 गुना तक बढ़ जाता है। बोर्ड की ओर से शहर का एयर प्रदूषण चेक करने के लिए हर साल दिवाली के मौके …
More than 90% of Europeans living in cities are exposed to unsafe levels one of the most health damaging air pollutants, with Bulgaria having the dirtiest air among EU countries, says a new study by the European Environment Agency (EEA). Despite falling emission levels and reductions of some air pollutant …
Air pollution is dangerously high across many parts of Europe, resulting in premature deaths, ill health and huge economic losses linked to reduced crop yields, Europe's environmental watchdog said on Tuesday. While emissions of some pollutants have declined sharply in Europe in recent decades, more diesel cars and a rise …
"Climate Change 2013: The Physical Science Basis" is the contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. This comprehensive assessment of the physical aspects of climate change puts a focus on those elements that are relevant to understand past, document current, …
Conclave of change makers for clean air and sustainable mobility - a presentation by Dr. B. Nagappa at STEPPING TOGETHER: A Conclave of Changemakers for Clean Air and Sustainable Mobility held in New Delhi from September 26-27, 2013.
Reducing fossil-fuel emissions to safer levels would save millions of lives annually by the end of the century, a study said on Sunday. The estimate is based on a simulation of levels of two big pollutants, fine particulate matter and ozone, from coal, oil and gas. The researchers led by …
Actions to reduce greenhouse gas (GHG) emissions often reduce co-emitted air pollutants, bringing co-benefits for air quality and human health. Past studies typically evaluated near-term and local co-benefits, neglecting the long-range transport of air pollutants long-term demographic changes, and the influence of climate change on air quality. Here we simulate …
Methane and natural debt and impacts on India’s workers of extreme climate change - a presentation by Kirk R. Smith at CSE Annual South Asian Media Briefing Workshop on Climate Change, 2013 held in New Delhi from September 18-19, 2013.
Ozone and fine-particle pollution worsened China's air quality in August compared with July, the Environmental Protection Ministry reported on its website on Tuesday. Twenty-eight of the 74 cities mentioned in the report had good air quality for at least 24 days in August. The number of such cities in July …
By the end of this century it’s going to be hotter than ever – the average day temperature in Tamil Nadu, now 32.9 degree Celsius is likely to go up by 3.1 degree Celsius. This was the finding of a study conducted by a team of researchers at the Centre …
Air quality officials are warning San Joaquin Valley residents of potential health hazards because of increasing ozone levels and smoke from lingering wildfires. The San Joaquin Valley Air Pollution Control District issued an air alert, the second this year, on Monday for San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings and …
Under the provisions of the Air (Prevention & Control of Pollution) Act, 1981, the CPCB has notified fourth version of National Ambient Air Quality Standards (NAAQS) in 2009. This revised national standard aims to provide uniform air quality for all, irrespective of land use pattern, across the country. There are …
This report, Current Challenges and Priorities for Greenhouse Gas Emission Factor Improvement in Select Asian Countries, focuses on a key initiative of the LEAD program, namely to improve GHG inventories and GHG accounting systems and practices. The national GHG inventories in Asia exhibit diversity in their methodological complexity, accuracy, and …
