Heavy industry is an industry that involves one or more characteristics such as large and heavy products; large and heavy equipment and facilities (such as heavy equipment, large machine tools, huge buildings and large-scale infrastructure); or complex or numerous processes. Because of those factors, heavy industry involves higher capital intensity than light industry does, and is also often more heavily cyclical in investment and employment.
Though important to economic development and industrialization of economies, heavy industry can also have significant negative side effects: both local communities and workers frequently encounter health risks, heavy industries tend to produce byproducts that both pollute the air and water, and the industrial supply chain is often involved in other environmental justice issues from mining and transportation. Because of their intensity, heavy industries are also significant contributors to greenhouse gas emissions that cause climate change, and certain parts of the industries, especially high-heat processes used in metal working and cement production, are hard to decarbonize. [1] Industrial activities such as mining also results in pollution consisting of heavy metals. Heavy metals are very damaging to the environment because they cannot be chemically degraded. [2]
Transportation and construction along with their upstream manufacturing supply businesses have been the bulk of heavy industry throughout the industrial age, along with some capital-intensive manufacturing. Traditional examples from the mid-19th century through the early 20th included steelmaking, artillery production, locomotive manufacturing, machine tool building, and the heavier types of mining. From the late 19th century through the mid-20th, as the chemical industry and electrical industry developed, they involved components of both heavy industry and light industry, which was soon also true for the automotive industry and the aircraft industry. Modern shipbuilding (since steel replaced wood) and large components such as ship turbochargers are also characteristic of heavy industry. [3]
A typical heavy industry activity is the production of large systems, such as the construction of skyscrapers and large dams during the post–World War II era, and the manufacture/deployment of large rockets and giant wind turbines through the 21st century. [4]
Many East Asian countries relied on heavy industry as key parts of their development strategies, [5] and many still do for economic growth. [6] This reliance on heavy industry is typically a matter of government economic policy. Among Japanese and Korean firms with "heavy industry" in their names, many are also manufacturers of aerospace products and defense contractors to their respective countries' governments such as Japan's Mitsubishi Heavy Industries and Fuji Heavy Industries, and Korea's Hyundai Rotem, a joint project of Hyundai Heavy Industries and Daewoo Heavy Industries. [7]
In 20th-century communist states, the planning of the economy often focused on heavy industry as an area for large investments (at the expense of investing in the greater production of in-demand consumer goods), even to the extent of painful opportunity costs on the production–possibility frontier (classically, "lots of guns and not enough butter"). [8] This was motivated by fears of failing to maintain military parity with foreign capitalist powers. For example, the Soviet Union's industrialization in the 1930s, with heavy industry as the favored emphasis, sought to bring its ability to produce trucks, tanks, artillery, aircraft, and warships up to a level that would make the country a great power. China under Mao Zedong pursued a similar strategy, eventually culminating in the Great Leap Forward of 1958–1960; an unsuccessful attempt to rapidly industrialize and collectivize, that led to the largest famine in human history, killing up to 50 million people, whilst simultaneously severely depleting the production of agricultural products and not increasing the output of usable-quality industrial goods. [9] [10]
Heavy industry is also sometimes a special designation in local zoning laws, allowing placement of industries with heavy impacts (on environment, infrastructure, and employment) with planning. For example, the zoning restrictions for landfills usually take into account the heavy truck traffic that will exert expensive wear on the roads leading to the landfill. [11]

As of 2019 [update] , heavy industry emits about 22% of global greenhouse gas emissions: high temperature heat for heavy industry being about 10% of global emissions. [12] The steel industry alone was responsible for 7 to 9% of the global carbon dioxide emissions which is inherently related to the main production process via reduction of iron with coal. [13] In order to reduce these carbon dioxide emissions, carbon capture and utilization and carbon capture and storage technology is looked at. Heavy industry has the advantage of being a point source which is less energy-intensive to apply the latter technologies and results in a cheaper carbon capture compared to direct air capture.

Industrial activities such as the improper disposal of radioactive material, burning coal and fossil fuels, and releasing liquid waste into the environment contribute to the pollution of water, soil, air, and wildlife. [14]
In regards to water pollution, when waste is disposed of in the environment, it affects the quality of the available water supply which has a negative impact on the ecosystem along with water supply used by farms for irrigation which in turn affects crops. [14] Heavy metals have also been shown to pollute soil, deteriorating arable land quality and adversely impacting food safety (such as vegetables or grain). [15] This occurs as a result of heavy industry when those heavy metals sink into the ground contaminating the crops that reside among it. [16]
Heavy metal concentrations resulting from water and/or soil pollution can become deadly once they pass certain thresholds, which lead to plant poisoning. [17] Heavy metals can further affect many levels of the ecosystem through bioaccumulation, because humans and many other animals rely on these plant species as sources of food. Plants can pick up these metals from the soil and begin the metal transfer to higher levels of the food chain, and eventually reaching humans. [18]
Regarding air pollution: long-term or short-term exposure of children to industry-based air pollution can cause several adverse effects, such as cardiovascular diseases, respiratory diseases and even death. Children are also more susceptible to air pollution detriments than adults. [19] Heavy metals such as lead, chromium, cadmium, and arsenic form dust fall particles and are harmful to the human body, with the latter two being carcinogens. [20] As a result of pollution, the toxic chemicals released into the atmosphere also contributes to global warming due to the increase of radiation absorbed. [21]
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.
The environment of China comprises diverse biotas, climates, and geologies. Rapid industrialization, population growth, and lax environmental oversight have caused many environmental issues and large-scale pollution.
Water pollution is the contamination of water bodies, with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.
Human impact on the environment refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation, mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species.
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons, solvents, pesticides, lead, and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical substance. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapour from the contaminants, or from secondary contamination of water supplies within and underlying the soil. Mapping of contaminated soil sites and the resulting clean ups are time-consuming and expensive tasks, and require expertise in geology, hydrology, chemistry, computer modelling, and GIS in Environmental Contamination, as well as an appreciation of the history of industrial chemistry.
The Ministry of Environment is the South Korea branch of government charged with environmental protection. In addition to enforcing regulations and sponsoring ecological research, the Ministry manages the national parks of South Korea. Its headquarters is in Sejong City.
The industrialization of China refers to the process of China undergoing various stages of industrialization and technological revolutions. The focus is on the period after the founding of the People's Republic of China where China experienced its most notable transformation from a largely agrarian country to an industrialized powerhouse. Although the Chinese industrialization is largely defined by its 20th-century campaigns, especially those motivated by Mao Zedong's political calls to "exceed the UK and catch the USA", China has a long history that contextualizes the proto-industrial efforts, and explains the reasons for delay of industrialization in comparison to Western countries.
Pollution in China is one aspect of the broader topic of environmental issues in China. Various forms of pollution have increased following the industrialisation of China, causing widespread environmental and health problems.
Environmental policy in China is set by the National People's Congress and managed by the Ministry of Environmental Protection of the People's Republic of China. Under the Ministry of Environmental Protection of the People's Republic of China, the Department of Policies, Laws, and Regulations is in charge of establishing and strengthening basic laws and policies such as environmental laws, administrative policies and economical regulations. It is also responsible for the development of national environmental protection policy and macro strategy.
The environmental impacts of animal agriculture vary because of the wide variety of agricultural practices employed around the world. Despite this, all agricultural practices have been found to have a variety of effects on the environment to some extent. Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. Meat is obtained through a variety of methods, including organic farming, free-range farming, intensive livestock production, and subsistence agriculture. The livestock sector also includes wool, egg and dairy production, the livestock used for tillage, and fish farming.

The environmental impact of paper are significant, which has led to changes in industry and behaviour at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, disposable paper became a relatively cheap commodity, which led to a high level of consumption and waste. The rise in global environmental issues such as air and water pollution, climate change, overflowing landfills and clearcutting have all lead to increased government regulations. There is now a trend towards sustainability in the pulp and paper industry as it moves to reduce clear cutting, water use, greenhouse gas emissions, fossil fuel consumption and clean up its influence on local water supplies and air pollution.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continue to raise concerns over environmental pollution.
The environmental impact of the energy industry is significant, as energy and natural resource consumption are closely related. Producing, transporting, or consuming energy all have an environmental impact. Energy has been harnessed by human beings for millennia. Initially it was with the use of fire for light, heat, cooking and for safety, and its use can be traced back at least 1.9 million years. In recent years there has been a trend towards the increased commercialization of various renewable energy sources. Scientific consensus on some of the main human activities that contribute to global warming are considered to be increasing concentrations of greenhouse gases, causing a warming effect, global changes to land surface, such as deforestation, for a warming effect, increasing concentrations of aerosols, mainly for a cooling effect.
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.
Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by chemicals emitted from mining processes. These processes also affect the atmosphere through carbon emissions which contributes to climate change.
Environmental issues in Chile include deforestation, water scarcity, pollution, soil erosion, climate change, and biodiversity loss, especially in its industry-heavy "sacrifice zones". The country of Chile is a virtual continental island that spans over 4,200 kilometers. It is bounded by the Pacific Ocean on the west, the Andes Mountains on the east, and the Atacama Desert in the north; it is home to several important eco-regions, such as the Chilean Winter Rainfall-Valdivian Forests, a biodiversity hot-spot that harbors richly endemic flora and fauna, and the Tropical Andes, which stretches into northern Chile. The country has a wide variety of climates due to its large size and extreme geographical features including glaciers, volcanoes, rain forests, and deserts. Chile faces many environmental issues that impact both its people and economy.
A sacrifice zone or sacrifice area is a geographic area that has been permanently changed by heavy environmental alterations or economic disinvestment, often through locally unwanted land use (LULU). Commentators including Chris Hedges, Joe Sacco, and Steve Lerner have argued that corporate business practices contribute to producing sacrifice zones. A 2022 report by the United Nations highlighted that millions of people globally are in pollution sacrifice zones, particularly in zones used for heavy industry and mining.
Foreign direct investment and the environment involves international businesses and their interactions and impact on the natural world. These interactions can be observed through the stringency applied to foreign direct investment policy and the responsiveness of capital or labor incentive for investment inflows. The laws and regulations created by a country that focuses on environmental regimes can directly impact the levels of competition involving foreign direct investment they are exposed to. Fiscal and financial incentives stemming from ecological motivators, such as carbon taxation, are methods used based on the desired outcome within a country in order to attract foreign direct investment.
The COVID-19 pandemic has had an impact on the environment, with changes in human activity leading to temporary changes in air pollution, greenhouse gas emissions and water quality. As the pandemic became a global health crisis in early 2020, various national responses including lockdowns and travel restrictions caused substantial disruption to society, travel, energy usage and economic activity, sometimes referred to as the "anthropause". As public health measures were lifted later in the pandemic, its impact has sometimes been discussed in terms of effects on implementing renewable energy transition and climate change mitigation.
