The Emergence of Environmental Sociology: From HEP to NEP

For most of modern history, Western societies operated under a bold assumption: humans are special enough to be free from the laws of nature. This belief shaped everything from industrial policy to academic scholarship. But by the 1970s, mounting ecological crises forced a rethinking. The field of environmental sociology emerged precisely at this turning point – driven by a paradigm shift from viewing humans as exempt from nature to recognizing our deep dependence on ecological systems. This shift, from the Human Exemptionalism Paradigm (HEP) to the New Ecological Paradigm (NEP), remains one of the most important intellectual developments in how we understand the relationship between society and the environment.

What is the Human Exemptionalism Paradigm (HEP)? 🔗

The Human Exemptionalism Paradigm is a term coined by sociologists William R. Catton Jr. and Riley E. Dunlap in the late 1970s. It describes the dominant worldview embedded not just in Western culture, but within the discipline of sociology itself – that humans, thanks to culture and technology, are fundamentally separate from and superior to the rest of nature.

Core assumptions of HEP 🔗

HEP rests on several interconnected assumptions. First, it holds that humans are fundamentally different from all other species because of their unique cultural heritage. Unlike biological traits, culture can change rapidly, accumulate knowledge, and innovate without limit. Second, social and cultural factors – not the biophysical environment – are considered the primary drivers of human affairs. The natural world, in this view, is largely irrelevant to understanding social life. Third, because culture is cumulative and technology always advances, all problems (including environmental ones) are ultimately solvable. Progress, therefore, never needs to stop.

This paradigm was not just a public attitude – it was deeply woven into academic sociology. Mainstream sociological theory from the late 19th century through the mid-20th century focused almost exclusively on social facts to explain social outcomes, treating the biophysical world as a backdrop rather than a factor. Whether looking at Marxist class theory, Weberian bureaucratic models, or structural functionalism, the environment simply did not feature as a meaningful variable.

Why HEP dominated for so long 🔗

There were historical reasons for this blind spot. Sociology, in its early development, was working hard to distinguish itself from biological determinism – the racist, colonialist idea that environment and biology dictated social outcomes. To carve out its own intellectual territory, the discipline leaned heavily into the idea that social structures and culture explain social life. The biophysical environment was pushed aside in the process. As Catton and Dunlap argued, this created a discipline that was poorly equipped to understand or respond to the growing environmental crises of the 20th century.

The industrial era reinforced this exemptionalist thinking at a societal level, too. Rapid economic growth, medical advances, and technological breakthroughs seemed to confirm that human ingenuity could overcome any natural limitation. For decades, this appeared to be working – at least on the surface.

The shift to the New Ecological Paradigm (NEP) 🔗

By the 1970s, cracks in the HEP worldview were impossible to ignore. Pollution, resource depletion, biodiversity loss, and growing evidence of ecological interdependence made it clear that societies could not simply innovate their way out of environmental limits. This prompted Catton and Dunlap to propose an alternative framework: the New Ecological Paradigm (NEP).

Core assumptions of NEP 🔗

The NEP does not deny that humans have exceptional characteristics – culture, technology, complex social organization. But it insists that these traits do not exempt us from ecological principles. Its key assumptions are a direct challenge to HEP:

First, humans are one species among many, interdependently involved in global ecosystems. Our social life is shaped by biotic communities, not just by cultural forces. Second, human actions produce unintended consequences – the cause-and-effect linkages in ecological systems mean that purposive action often creates outcomes we did not plan for or expect. Third, the world is finite. There are real physical and biological limits constraining economic growth, social progress, and other societal activities. These are not problems that technology can endlessly overcome.

It is worth noting, as scholars like McDonald and Patterson (2007) have pointed out, that the NEP is still fundamentally anthropocentric – it must be, to remain a sociological paradigm. However, it differs from HEP by acknowledging humanity’s critical dependence on the environment rather than dismissing it.

From “exceptionalism” to “exemptionalism” 🔗

An interesting detail: Catton and Dunlap originally called HEP the Human Exceptionalism Paradigm. They later changed the name to Human Exemptionalism Paradigm to clarify their argument. They were not questioning that humans have exceptional characteristics – clearly, we do. The issue was the assumption that those characteristics exempt us from ecological constraints. The revised terminology made this distinction sharper.

Similarly, the alternative paradigm was initially called the New Environmental Paradigm before being renamed the New Ecological Paradigm to emphasise the ecological foundation of human society rather than just environmental concern.

The NEP scale: measuring environmental attitudes 🔗

The HEP-NEP distinction was not just theoretical. Dunlap and colleagues developed the NEP Scale, a widely used survey instrument designed to measure the degree to which individuals hold ecological versus exemptionalist worldviews. The scale assesses beliefs about ecological limits, the balance of nature, human dominance over nature, and the likelihood of ecological crises.

Since its creation, the NEP Scale has been applied in dozens of countries across various demographic groups. Researchers have used it to study the relationship between ecological worldviews and pro-environmental behaviour, support for environmental policy, and attitudes toward sustainability. While the scale has its critics – some argue its dimensions are not always stable across cultures – it remains one of the most commonly used tools in environmental attitude research.

The role of environmental movements in sparking the paradigm shift 🔗

The intellectual shift from HEP to NEP did not happen in an academic vacuum. It was propelled by a broader awakening in public consciousness about the environment, driven by key events and publications that forced both citizens and scholars to rethink humanity’s relationship with nature.

Rachel Carson’s Silent Spring (1962) 🔗

Few books have reshaped public thought as profoundly as Silent Spring. Published in 1962, Rachel Carson’s work exposed the hazards of the pesticide DDT and questioned the prevailing faith in technological progress. Carson documented how pesticides entered food chains, accumulated in animal tissues, and caused widespread ecological damage – from bird population declines to contamination of water sources.

The book faced fierce opposition from the chemical industry, but its scientific claims were validated by a presidential science advisory committee under President John F. Kennedy. More importantly, it shifted public understanding of a fundamental point: human industrial activity could harm ecosystems in ways that ultimately threatened human health and well-being.

Silent Spring is widely credited with catalysing the modern environmental movement. It contributed directly to the establishment of the U.S. Environmental Protection Agency in 1970 and the eventual ban on DDT for agricultural use in 1972. For environmental sociology, Carson’s work provided concrete, documented evidence that societies and ecosystems are deeply entangled – a direct challenge to the HEP worldview.

The first Earth Day (1970) 🔗

On April 22, 1970, the first Earth Day brought environmental issues into mainstream political life. Proposed by U.S. Senator Gaylord Nelson and organised by activist Denis Hayes, the event drew participation from over 20 million Americans across thousands of schools, universities, and communities. It is widely recognised as the birth of the U.S. environmental movement as a political force.

Earth Day was not an isolated event. It built on the momentum of other social movements of the 1960s – civil rights, anti-war activism, women’s rights – and channelled public frustration over visible environmental degradation. Oil spills, river fires, and urban smog had already shocked the public. Earth Day turned that shock into political action.

The political impact was immediate and significant. By the end of 1970, President Richard Nixon had created the Environmental Protection Agency and signed the Clean Air Act into law. The Endangered Species Act, Clean Water Act, and other landmark legislation followed in the early 1970s. This period saw more environmental laws passed than any other era in U.S. history.

Other key catalysts 🔗

Beyond Carson and Earth Day, several other developments fuelled the paradigm shift. The 1969 oil spill in Santa Barbara, California, which dumped millions of gallons of crude oil into the Pacific, was a visceral demonstration of industrial recklessness. The Cuyahoga River in Cleveland catching fire – a river so polluted it burned – became a symbol of environmental neglect. Paul Ehrlich’s The Population Bomb (1968) and the Club of Rome’s The Limits to Growth (1972) raised alarm about resource depletion and overpopulation.

These events and publications created the social and political context within which environmental sociology could take root. Public concern about the environment was no longer fringe – it was mainstream. And for sociologists like Catton and Dunlap, it was time for the discipline to catch up.

The growth and challenges of environmental sociology 🔗

Environmental sociology formally emerged as a sub-discipline in the 1970s, directly tied to the wave of environmental concern sweeping Western societies. Catton and Dunlap’s foundational work established the HEP-NEP framework and called on sociology to take the biophysical environment seriously as a variable shaping social life.

However, the field’s trajectory has not been smooth. Interest in environmental sociology declined in the early 1980s as public and political attention to environmental issues waned. The broader discipline’s ingrained exemptionalist assumptions made it difficult for environmental sociology to gain a secure foothold. It was only with growing recognition of global environmental change – climate change, ozone depletion, biodiversity loss – from the late 1980s onward that the field experienced revitalization.

Today, environmental sociology encompasses several major theoretical traditions. These include the treadmill of production theory (emphasising how capitalism drives environmental degradation through continuous growth), ecological modernisation (exploring how industrial societies can reform themselves to reduce environmental harm), environmental justice (examining the unequal distribution of environmental risks across race and class), and continued work within the NEP framework.

Contemporary relevance of the HEP-NEP debate 🔗

The HEP-NEP distinction remains relevant today, even if the terms themselves are not always used. Debates about climate change, for instance, often reveal exemptionalist thinking. Arguments that technology alone will solve the climate crisis, or that economic growth should not be constrained by environmental concerns, echo the core assumptions of HEP. On the other side, calls for degrowth, ecological limits, and systems thinking reflect the NEP perspective.

Recent scholarship has also expanded the framework by connecting exemptionalist thinking to structures of social inequality. Some researchers argue that the belief in human dominance over nature is intertwined with patriarchal and colonial worldviews that have historically justified domination of both ecosystems and marginalised communities. This suggests that moving beyond HEP is not just an ecological necessity but a social justice imperative as well.

Why this paradigm shift matters 🔗

The shift from HEP to NEP is not just a piece of academic history. It represents a fundamental change in how we understand the place of human societies within the natural world. HEP treated the environment as a backdrop – something that existed for human use and could always be managed or overcome. NEP insists that we are embedded in ecological systems, subject to their limits, and affected by the consequences of our actions within them.

This matters for policy, for education, and for everyday life. Environmental sociology – and the NEP worldview that underpins it – provides the intellectual tools to understand why environmental problems are social problems, and why solving them requires more than just better technology. It requires rethinking the assumptions we hold about progress, growth, and our relationship with the planet.

What do you think? Do you see exemptionalist thinking still shaping how your society responds to environmental crises? And can a genuine shift toward the New Ecological Paradigm happen without also addressing deeper social inequalities?
