The environmental problems like global warming, acid rain, air pollution, urban sprawl, waste disposal, ozone layer depletion, water pollution, climate change and many more affect every human, animal and nation on this planet. As our actions have been not in favor of protecting this planet, we have seen natural disasters striking us more often in the form of flash floods, tsunamis and cyclones.
A peer-reviewed EPA Report to Congress reviewed the benefits of the Act from toand concluded that in alone, pollution reductions under the Act preventedearly deaths, Independent scientific research shows that reductions in air pollution are associated with widespread public health benefits.
For example, one study found that reductions in fine particle pollution between and in U. Lower air pollution levels mean less damage to the health of ecosystems.
Environmental effects of air pollution include damage to plants and long-term forest health, soil nutrient deterioration, accumulation of toxics in the food chain, damage to fish and other aquatic life in lakes and streams, and nitrogen enrichment of coastal estuaries causing oxygen depletion and resulting harm to fish and other aquatic animal populations.
Even the low benefits estimate exceeds costs by about 3-to In addition to direct benefits vastly exceeding direct costs, economy-wide modeling conducted for the study found that the economic welfare of American households is better with post clean air programs than without them.
Economic welfare and economic growth rates are improved because cleaner air means fewer air-pollution-related illnesses, which in turn means less money spent on medical treatments and lower absenteeism among American workers.
The study projects that the beneficial economic effects of these two improvements alone more than offset the expenditures for pollution control.
The EPA report received extensive review and input from the Council on Clean Air Compliance Analysis, an independent panel of distinguished economists, scientists and public health experts established by Congress in Top of Page New cars, trucks, and nonroad engines use state-of-the-art emission control technologies.
EPA has required dramatic reductions in emissions from new motor vehicles and non-road engines - such as those used in construction, agriculture, industry, trains and marine vessels -- through standards that require a combination of cleaner engine technologies and cleaner fuels. Compared to vehicle models, new cars, SUVs and pickup trucks are roughly 99 percent cleaner for common pollutants hydrocarbons, carbon monoxide, nitrogen oxides and particle emissionswhile Annual Vehicle Miles Traveled has dramatically increased.
New heavy-duty trucks and buses are roughly 99 percent cleaner than models. In MarchEPA finalized a three part program that dramatically reduces emissions from diesel locomotives of all types -- line-haul, switch, and passenger rail.
Clean Air Act and international standards for ocean-going vessel emissions and fuels are reducing emissions from ocean-going vessels as well. InEPA finalized findings that GHG emissions from certain classes of engines used in aircraft contribute to the air pollution that causes climate change endangering public health and welfare under section a of the Clean Air Act.
Top of Page New power plants and factories use modern pollution control technology. The Act requires that when new industrial facilities are designed and built, good pollution control must be part of the design. This means that as new, cleaner facilities are built, the country's industrial base becomes cleaner overall.
Public health is protected as economic growth proceeds. In areas that meet air quality standards, new and modified large plants and factories must apply the best available technology considering cost and avoid causing significant degradation of air quality or visibility impairment in national parks.
For example, new coal-fired power plants typically install control devices that capture up to 98 percent of the sulfur dioxide and in many cases 90 percent of the nitrogen oxide emissions, relative to uncontrolled levels.
These requirements are applied through pre-construction permitting programs that are administered by state, local, tribal, or EPA permitting authorities, depending on the location. State and local permitting authorities usually administer the pre-construction permit programs that determine how to apply these requirements to facilities.
Top of Page Power plants have cut emissions that cause acid rain and harm public health.
A national system of marketable pollution allowances has dramatically cut power plant emissions of sulfur dioxide, reducing acid rain as well as secondary formation of fine particle pollution that contributes to premature death. Acid rainwhich includes wet and dry deposition of acidic compounds from the atmosphere, results from emissions of sulfur dioxide and nitrogen oxides.
Reducing acid rain has significantly reduced damage to water quality in lakes and streams, and improved the health of ecosystems and forests. Between the to and to observation periods, wet deposition of sulfate which causes acidification decreased by more than 55 percent on average across the eastern United States.
The dramatic emissions reductions achieved by the acid rain program have helped to reduce atmospheric levels of fine particle pollution, avoiding numerous premature deaths.
Government and independent analyses have concluded that the benefits of the program far outweigh the costs, as detailed in the U. Top of Page Interstate air pollution has been reduced.
Further reductions in power plant pollution have been achieved by state and EPA efforts to cut interstate air pollution, achieving additional public health benefits and helping downwind states meet health-based air quality standards for fine particles and ozone.
Twelve New England and mid-Atlantic states and the District of Columbia -- the Ozone Transport Region created by the Amendments -- worked together to create a nitrogen oxides NOx Budget Program and to adopt other controls that help improve ozone levels throughout the region.
As ofthe program cut summertime NOx emissions from power plants by 62 percent from levels. These reductions, along with the NOx reductions from federal motor vehicle standards, are responsible for substantial improvement in ozone levels across the eastern United States.
CAIR, which had initial compliance deadlines in andis a major reason that almost all areas in the East have met the and air quality standards for fine particles. Top of Page Mobile and industrial pollution sources release far less toxic air pollution than in Stationary sources today emit about 1.
Toxic emissions from onroad and nonroad vehicles and engines also are dropping due to requirements for cleaner fuels and engines. Onroad and nonroad diesel particulate matter emissions decreased by about 27 percent from to and are projected to be reduced an additional 90 percent from to Airborne levels of benzene, a carcinogen found in gasoline, declined by 66 percent from to based on available air quality monitoring information.Apr 06, · The Clean Air and Sustainable Environment project (CASE) is helping tackle pollution from brickfields and transportation in Bangladesh.
So far, the project has encouraged the adoption of cleaner brick manufacturing technologies that decrease particulate emissions and greenhouse gas emissions, and is promoting safer . EPA uses voluntary partnership programs in tandem with regulatory programs to protect public health and the environment.
Clean Air Act partnership programs reduce conventional air pollution and greenhouse gas emissions, improve energy efficiency, reduce oil imports, and save money. An Overview Of Japan’s Environmental Issues And Policies May 23, August 18, Thomas Clark Japan is an East Asian Country comprising of four main islands and thousands of other small islands.
Environmental Pollution refers to the introduction of harmful pollutants into the environment. The major types of environmental pollution are air pollution, water pollution, noise pollution, soil pollution, thermal pollution, and light pollution.
Deforestation and hazardous gaseous emissions also leads to environmental pollution. Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.
Pollutants in the air aren't always visible and come from many different sources. Climate Air Pollution Smog hanging over cities is the most familiar and obvious form of air pollution.
