Building on the strong progress made under President Obama to curb the emissions that are driving climate change and lead on the international stage, today the United States submitted its target to cut net greenhouse gas emissions to the United Nations Framework Convention on Climate Change UNFCCC. Last November, President Obama and President Xi — leaders of the largest economies and largest polluters — made the historic announcement of the respective post climate targets for the United States and China. For the first time, China committed to limit its greenhouse gas emissions, with a commitment to peak emissions around and to make best efforts to peak early, and to increase its share of non-fossil energy consumption to around 20 percent by
Space 5 Brilliant Solutions to Air Pollution A variety of measures has been undertaken or proposed and instituted to curb the effects of air pollution. Solving the air pollution problem requires joint effort and takes different ways from one region to another. For example, it primarily requires behavior change and institutionalization of measures that can considerably ameliorate the situation in the short-term and the long-term.
Ordinarily, the solutions to air pollution have focused on establishing a mix of technological solutions, regulations and policies, and encouraging behavioral change. Cleaning Smokestacks and Exhaust Pipes The leading sources of air pollution are power plants, factories, and vehicles. They constantly emit fumes and gaseous waste into the atmosphere.
In power plants and manufacturing industries, electrostatic smoke precipitators that use static electricity to trap soot and dust from the gaseous waste leaving the smokestacks is a significant technological cleaning measure which can be used to control air pollution.
Flue-gas desulfurization FGDcommonly referred to as scrubbing, is as well another means of providing a technical solution to Sulfur Oxide emissions.
Scrubbing is a process that chemically eliminates the sulfur oxide gasses leaving the smokestacks. Power plans can also be retrofitted with carbon capturing technologies that trap emitted carbon dioxide.
Vehicles with gasoline powered engines are fitted with catalytic converters on the exhaust pipe to reduce the exhaust gas emissions. Constant improvements to gasoline that combusts cleaner and production of more energy efficient cars have been an additional strategy for reducing vehicle emissions.
All these processes and methods are called emission reduction strategies. Laws and Regulations Some national and state or international policies can be used to control air pollution.
Legislation and regulations always offer a fantastic measure for tackling the air pollution menace.
Many cities and countries that were once heavily polluted have substantially attained clean air mainly due to the institutionalization of anti-pollution laws. In England, for instance, following the smog tragedy that claimed thousands of lives in London, the government launched its Clean Air Act of which placed limits on burning coal and required industries to build higher smokestacks.
International cooperation and organizations such as the European Union EUUnited Nations UNand environmental programs have also devised clean air acts and directives to reduce air pollution. A number of states and governing actions or policies can also be undertaken to reduce emissions.
Quality air control protocols and standards such as the installation of pollution control devices or buying emission allowance can be used effectively as execution strategies for reducing the adverse effects of air pollution.
Use of Renewable or Green Energy Sources Fossil fuel and coal are the main contributors to air pollutio n. Therefore, opting for alternative or renewable energy sources to produce power presents a practical solution to air pollution.
Alternative energy sources include wind energy, geothermal energy, solar energy, and hydro-power. If people can harness a variety of these energy sources instead of relying on fossil fuels or coal energy, air pollution can reduce more than threefold.Despite dramatic progress cleaning the air since , air pollution in the United States continues to harm people’s health and the environment.
Under the Clean Air Act, EPA continues to work with state, local and tribal governments, other federal agencies, and stakeholders to . Air pollution can cause a variety of health problems including, but not limited to infections, behavioral changes, cancer, organ failure, and even premature death.
These health effects are not equally distributed in terms of race, ethnicity, socioeconomic status, education, and more in the United States.
Pollution in China can change weather patterns in the United States. It takes just five days for the jet stream to carry heavy air pollution from China to the United States, where it stops clouds.
Oct 08, · Nearly 50 years ago, environmental disasters in the United States spurred a popular movement that culminated in new protections and helped to .
The United States currently generates million tons of trash per year, or 7 pounds per person per day. Municipal solid waste, or MSW, commonly known as garbage, gets picked up from homes and.
Aug. 9 (UPI) --New research suggests federal environmental regulations enacted under the Clean Air Act are responsible for significant reductions in air pollution emissions over the last several.
