The Clean Air Act 1956 (4 & 5 Eliz. 2. c. 52) was an Act of the Parliament of the United Kingdom enacted principally in response to London's Great Smog of 1952. It was sponsored by the Ministry of Housing and Local Government in England and the Department of Health for Scotland, and was in effect until 1993.
The Act introduced a number of measures to reduce air pollution. Primary among them was mandated movement toward smokeless fuels, especially in high-population "smoke control areas" to reduce smoke pollution and sulphur dioxide from household fires. The Act also included measures that reduced the emission of gases, grit, and dust from chimneys and smoke-stacks.
The Act was a significant milestone in the development of a legal framework to protect the environment. [1] It was modified by later enactments, including the Clean Air Act 1968. [2]
The Act was repealed by the Clean Air Act 1993. [2]
London had long been noted for its pea soup fog. [3] In 1880, meteorologist Rollo Russell wrote an influential pamphlet, London Fogs, noting that "numerous deaths occur in the course of the year from smoke-fogs, not unusually thick, producing or increasing diseases of the lungs". [4]
London had seen a succession of acts and rules over the centuries to improve its air—such as the Smoke Nuisance Abatement (Metropolis) Act 1853 and 1856 and the Public Health (London) Act 1891. However, despite the link between air pollution and health being well understood by the late 19th century, such efforts had not proven to be effective public health measures. [5]
When the "Great Smog" fell over the city in December 1952 the effects were unprecedented: More than 4,000 people are thought to have died in the immediate aftermath, [6] raising public concern, with fog so thick it stopped trains, cars, and public events. [7] [8] A further 8,000 died in following weeks and months. Today, the total death toll is believed to be around 12,000. [9]
It was apparent that pollution was a real and deadly problem, and the smog's effects were a notable milestone in the modern environmental movement.
The government appointed a Committee on Air Pollution chaired by the civil engineer Sir Hugh Beaver to investigate the problem in London. [10] It reported in 1954 [11] on the social and economic costs of air pollution and stated that clean air was then as important as clean water had been in the mid-nineteenth century. The committee proposed that domestic coal should be replaced by coke, and that greater reliance should be placed on other 'smokeless' fuels such as electricity and gas. Yet, each of the industries that produced smokeless fuels – coke and gas works and electricity generating stations – burned coal to produce the 'smokeless' fuel. For example, the six million tons of coal a year that were converted to coke in North-East England in the late nineteenth century emitted some two million tons of volatile matter such as carbonic and sulphurous acid. [12] Therefore, air pollution was not being reduced so much as transferred from the area of consumption to the area of production.
The electricity generating industry was a major consumer of coal and contributor to atmospheric pollution. The Beaver committee used the example of the recently commissioned Bankside power station in London to recommend the widespread adoption of flue-gas desulphurisation for all new power stations in urban areas. [13] It claimed that this would be practicable and cost-effective if it added no more than 0.06 d. to 0.07 d. to the cost of a unit of electricity (1 kWh).
The British Electricity Authority was sceptical about the benefits of desulphurisation and challenged the committee's recommendations. The Authority stated that this recommendation "strikes a damaging blow against the economy of electricity development in this country" and that the financial implications "are potentially more serious than those of any previous restrictions or control imposed upon the Authority's activities". [13] The Authority claimed that installing scrubbers in all power stations would entail an annual capital investment of £10 million and would increase the cost of electricity by 0.1 d. per kWh, therefore exceeding the cost-effectiveness criterion suggested in the draft Beaver report. The British Electricity Authority was also critical that the Beaver committee had made no serious attempt to assess the relative economics of different ways of reducing atmospheric pollution. It claimed that burning coal in modern power station boilers that were equipped with efficient grit collectors and into tall chimneys was "an extremely efficient method of controlling pollution in terms ... of capital outlay". [13]
The government initially resisted pressure to act, and was keen to downplay the scale of the problem due to economic pressures. [14] It took moves by backbench MPs (including Conservative member Gerald Nabarro, its sponsor [15] ) to pass a Private Member's Bill on domestic coal burning to persuade the Government to support a change in the law. The Clean Air Act built on earlier efforts to regulate pollutants, particularly in London, where air quality had long been poor.
The Clean Air Act 1956 had multiple measures to reduce air pollution. It allowed the introduction of "smoke control areas" in towns and cities in which only smokeless fuels could be burned. By shifting domestic sources of heat towards cleaner coals, electricity, and gas, it reduced the amount of smoke pollution and sulphur dioxide from household fires. Reinforcing these changes, the Act also included provisions to prevent the emission of dark smoke from chimneys, required new furnaces to be smokeless, allowed local planning authorities to require higher and more effective chimneys on buildings, and required that emitted grit and dust be minimised. By prohibiting what had been the hitherto widely accepted actions of private households, the Clean Air Act 1956 had important implications for the debate about public regulation, public health, and the sphere of legitimate Government intervention. [16]
The 1952 smog gave a momentum for tougher action: as well as the Clean Air Act, its effects also led to the introduction of the City of London (Various Powers) Act 1954, and later the Clean Air Act 1968.
Smog and its health effects continued to be a problem in London. During the London fog of 2–5 December 1957 smoke and sulphur dioxide concentrations reached levels comparable to 1952 and there were 760–1,000 deaths. [17] Another episode in 1962 resulted in 750 deaths. [18]

Text of statute as originally enacted |
The provisions of the 1956 act were extended by the Clean Air Act 1968 (c. 62), which made it an offence to emit dark smoke from a chimney, empowered the Minister to define limits for emissions of grit and dust from furnaces, defined requirements for arrestment plant to be fitted to new furnaces, and provided a framework for control of the height and position of chimneys. The Act also allowed the Minister to create smoke control areas and introduce controls on use of unauthorised fuel in such areas. [19]
The 1956 and 1968 Clean Air Acts were repealed by the Clean Air Act 1993, [20] which consolidated and extended the provisions of the earlier legislation.
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.
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words smoke and fog to refer to smoky fog due to its opacity, and odor. The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid-20th century, where it was commonly known as a London particular or London fog. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions.
The Great Smog of London, or Great Smog of 1952, was a severe air pollution event that affected London, England, in December 1952. A period of unusually cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday 5 December to Tuesday 9 December 1952, then dispersed quickly when the weather changed.
Bankside Power Station is a decommissioned electricity generating station located on the south bank of the River Thames, in the Bankside area of the Borough of Southwark, London. It generated electricity from 1891 to 1981. It was also used as a training base for electrical and mechanical student apprenticeships from all over the country. Since 2000 the building has housed the Tate Modern art museum and gallery.
A stove or range is a device that generates heat inside or on top of the device, for local heating or cooking. Stoves can be powered with many fuels, such as electricity, natural gas, gasoline, wood, and coal.
The 1939 St. Louis smog was a severe smog episode that affected St. Louis, Missouri on November 28, 1939. Visibility was so limited that streetlights remained lit throughout the day and motorists needed their headlights to navigate city streets.
Coal pollution mitigation, sometimes labeled as clean coal, is a series of systems and technologies that seek to mitigate health and environmental impact of burning coal for energy. Burning coal releases harmful substances, including mercury, lead, sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2), contributing to air pollution, acid rain, and greenhouse gas emissions. Methods include flue-gas desulfurization, selective catalytic reduction, electrostatic precipitators, and fly ash reduction focusing on reducing the emissions of these harmful substances. These measures aim to reduce coal's impact on human health and the environment.
The Air Pollution Control Act of 1955 was the first U.S. federal law to address the national environmental problem of air pollution. This was "an act to provide research and technical assistance relating to air pollution control". The act "left states principally in charge of prevention and control of air pollution at the source". The act declared that air pollution was a danger to public health and welfare, but preserved the "primary responsibilities and rights of the states and local government in controlling air pollution".
Smokeless fuel is a type of solid fuel which either does not emit visible smoke or emits minimal amounts during combustion. These types of fuel find use where the use of fuels which produce smoke, such as coal and unseasoned or wet wood, is prohibited.
Environmental Protection UK is a UK environmental non-governmental organisation (NGO) working to improve the quality of the local environment - specialising in the subjects of air quality, noise management and land quality. It was formerly known as the National Society for Clean Air and Environmental Protection (NSCA), changing its name 2007, to reflect ongoing work in fields beyond air quality.
A wood-burning stove is a heating or cooking appliance capable of burning wood fuel, often called solid fuel, and wood-derived biomass fuel, such as sawdust bricks. Generally the appliance consists of a solid metal closed firebox, often lined by fire brick, and one or more air controls. The first wood-burning stove was patented in Strasbourg in 1557. This was two centuries before the Industrial Revolution, so iron was still prohibitively expensive. The first wood-burning stoves were high-end consumer items and only gradually became used widely.
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.
Pea soup fog is a very thick and often yellowish, greenish or blackish fog caused by air pollution that contains soot particulates and the poisonous gas sulphur dioxide. This very thick smog occurs in cities and is derived from the smoke given off by the burning of soft coal for home heating and in industrial processes. Smog of this intensity is often lethal to vulnerable people such as the elderly, the very young (infants) and those with respiratory problems. The result of these phenomena was commonly known as a London particular or London fog; in a reversal of the idiom, "London particular" became the name for a thick pea and ham soup.
Air quality laws govern the emission of air pollutants into the atmosphere. A specialized subset of air quality laws regulate the quality of air inside buildings. Air quality laws are often designed specifically to protect human health by limiting or eliminating airborne pollutant concentrations. Other initiatives are designed to address broader ecological problems, such as limitations on chemicals that affect the ozone layer, and emissions trading programs to address acid rain or climate change. Regulatory efforts include identifying and categorising air pollutants, setting limits on acceptable emissions levels, and dictating necessary or appropriate mitigation technologies.
Air pollution in the United Kingdom has long been considered a significant health issue, and it causes numerous other environmental problems such as damage to buildings, forests, and crops. Many areas, including major cities like London, are found to be significantly and regularly above legal and recommended pollution levels. Air pollution in the UK is a major cause of diseases such as asthma, lung disease, stroke, cancer, and heart disease, and is estimated to cause forty thousand premature deaths each year, which is about 8.3% of deaths, while costing around £40 billion each year.
United Kingdom environmental law concerns the protection of the environment in the United Kingdom. Environmental law is increasingly a European and an international issue, due to the cross border issues of air and water pollution, and man-made climate change.
The 1966 New York City smog was a major air-pollution episode and environmental disaster, coinciding with that year's Thanksgiving holiday weekend. Smog covered the city and its surrounding area from November 23 to 26, filling the city's air with damaging levels of several toxic pollutants. It was the third major smog in New York City, following events of similar scale in 1953 and 1963.
Air pollution in Germany has significantly decreased over the past decade. Air pollution occurs when harmful substances are released into the Earth's atmosphere. These pollutants are released through human activity and natural sources. Germany took interest in reducing its greenhouse gas (GHG) emissions by switching to renewable energy sources. Renewable energy use rate from 6.3% in 2000 to 34% in 2016. Through the transition to renewable energy sources, some people believe Germany has become the climate change policy leader and renewable energy leader in the European Union (EU) and in the world with ambitious climate change programs, though Germany's CO
2 emissions per capita are in fact among the highest in Europe, almost twice those of e.g. France. The current goal of the German government was approved on 14 November 2016 in the German Climate Action Plan 2050, which outlines measures by which Germany can meet its greenhouse gas emissions by 2050. By 2050, Germany wants to reduce their GHGs by 80 to 95% and by 2030 they want to reduce it by 55%, compared to the EU target of 40%.
New Jersey Air Pollution Control Law consists of legislative and regulatory measures intended to limit the amount of harmful substances found in the air. In New Jersey, the federal Clean Air Act and the state Air Pollution Control Act (1954) are the most significant pieces of air pollution control legislation. These laws are implemented and enforced by the New Jersey Department of Environmental Protection (NJDEP).
The 1962 London smog was a severe smog episode that affected London, England, in December 1962. It occurred ten years after the Great Smog of London, in which serious air pollution had killed as many as 12,000 people. While the 1952 smog had led to the passing of the 1956 Clean Air Act, which restricted the burning of domestic fuels in urban areas with the introduction of smokeless zones, fogs continued to be smoky in London for some years after the act as residents and operators were given time to convert from domestic fuels. The December 1962 smog is thought to have led to the deaths of up to 700 people.
It remains a seminal piece of legislation because it created a belief that a better environment was possible and worthwhile despite the fact that at times it would restrict our individual freedom
