The Political Economy Research Institute (PERI) is an independent research unit at the University of Massachusetts Amherst. According to its mission statement, it "...promotes human and ecological well-being through our original research". PERI was established in 1998 by co-directors Robert Pollin and Gerald Epstein, both economists at the university. Funding for its foundation came from Pollin and his businessman father, Abe Pollin. [1]
PERI's Toxic 100 list includes one hundred United States companies ranked by the amount of greenhouse gases, air pollution and water pollution produced and the relative toxicity of the pollutants, as determined by PERI at the University of Massachusetts Amherst. [2]
The Greenhouse 100 Index ranks companies by 2019 direct emissions from large sources. The top three companies are Vistra Energy, Duke Energy, and Southern Company, continuing a three-year period in which these were in the top three. They each released more than 85 million metric tons of CO2-equivalent emissions. Together these three companies released 4 percent of all U.S. greenhouse gas emissions from all sources including non-energy sources. Rounding out the top 10 in the Greenhouse 100 are Berkshire Hathaway, American Electric Power, Xcel Energy, Energy Capital Partners, NextEra Energy, and Exxon Mobil, with the U.S. government ranking 6th. The Toxic 100 Air Polluters Index reports that the top 10 2019 companies in terms of total potential chronic human health risk are Boeing, LyondellBasell, Huntsman, Linde, BASF, Dow Inc., Celanese, Assa Abloy, Baker Hughes, and Eastman Chemical. The Toxic 100 Water Polluters Index ranks the pounds of toxics released into surface water or sent to water-treatment systems, adjusted for chemical toxicity. Northrop Grumman, Dow Inc., LyondellBasell, Celanese, and Canopus International top the Toxic 100 Water Index for 2019. [3]
Toxic 100 air pollution scores are calculated by the formula:
Emissions are measured in millions of pounds. Population exposure is based on the proximity of nearby residents, and factors such as prevailing winds and height of smokestacks. Toxicity is calculated from the Risk-Screening Environmental Indicators by the Environmental Protection Agency.
A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. These can be both naturally forming or anthropogenic in origin. Pollutants result in environmental pollution or become public health concerns when they reach a concentration high enough to have significant negative impacts.
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance or energy. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern called an exhaust plume.

Massachusetts v. Environmental Protection Agency, 549 U.S. 497 (2007), is a 5–4 U.S. Supreme Court case in which Massachusetts, along with eleven other states and several cities of the United States, represented by James Milkey, brought suit against the Environmental Protection Agency (EPA) represented by Gregory G. Garre to force the federal agency to regulate the emissions of carbon dioxide and other greenhouse gases (GHGs) that pollute the environment and contribute to climate change.
Environmental issues in New York City are affected by the city's size, density, abundant public transportation infrastructure, and location at the mouth of the Hudson River.
Robert Pollin is an American economist and professor at the University of Massachusetts Amherst, where he is also founding co-director of its Political Economy Research Institute (PERI).
Pollution in China is one aspect of the broader topic of environmental issues in China. Various forms of pollution have increased as China has industrialised, which has caused widespread environmental health problems.
Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents that alters the natural features of the atmosphere. There are many different types of air pollutants, such as gases, particulates, and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and crops, and may damage the natural environment or built environment. Air pollution can be caused by both human activities and natural phenomena.
Environmental issues in Canada include impacts of climate change, air and water pollution, mining, logging, and the degradation of natural habitats. As one of the world's significant emitters of greenhouse gasses, Canada has the potential to make contributions to curbing climate change with its environmental policies and conservation efforts.
Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere, causing harm or discomfort to humans or other living organisms, or damaging ecosystems. Air pollution can cause health problems including, but not limited to, infections, behavioral changes, cancer, organ failure, and premature death. These health effects are not equally distributed across the U.S. population; there are demographic disparities by race, ethnicity, socioeconomic status, and education. Air pollution can derive from natural sources, or anthropogenic sources. Anthropogenic air pollution has affected the United States since the beginning of the Industrial Revolution.
The Clean Air Act (CAA) is the United States' primary federal air quality law, intended to reduce and control air pollution nationwide. Initially enacted in 1963 and amended many times since, it is one of the United States' first and most influential modern environmental laws.
As with many countries, pollution in the United States is a concern for environmental organizations, government agencies and individuals.
Pollution in California relates to the degree of pollution in the air, water, and land of the U.S. state of California. Pollution is defined as the addition of any substance or any form of energy to the environment at a faster rate than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The combination of three main factors are the cause of notable unhealthy levels of air pollution in California: the activities of over 39 million people, a mountainous terrain that traps pollution, and a warm climate that helps form ozone and other pollutants. Eight of the ten cities in the US with the highest year-round concentration of particulate matter between 2013 and 2015 were in California, and seven out of the ten cities in the US with the worst ozone pollution were also in California. Studies show that pollutants prevalent in California are linked to several health issues, including asthma, lung cancer, birth complications, and premature death. In 2016, Bakersfield, California recorded the highest level of airborne pollutants of any city in the United States.
The environmental impact of the petroleum industry is extensive and expansive due to petroleum having many uses. Crude oil and natural gas are primary energy and raw material sources that enable numerous aspects of modern daily life and the world economy. Their supply has grown quickly over the last 150 years to meet the demands of the rapidly increasing human population, creativity, knowledge, and consumerism.
DuPont de Nemours, Inc., commonly shortened to DuPont, is an American multinational chemical company first formed in 1802 by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours.
