Environmental Justice and Equity

Pollution does not land evenly. Landfills, incinerators and waste exports consistently end up in the same kinds of places, and the people living there are rarely the ones who generated the waste. That pattern is what environmental justice is about.

📘 What you need to know

What environmental justice means

Environmental justice refers to the right of all people to live in a pollution-free environment and to have equitable — fair and equal — access to natural resources, regardless of race, gender, socio-economic status or nationality.

Definition Environmental justice — the right of all people to live in a pollution-free environment and to have equitable access to natural resources, regardless of race, gender, socio-economic status or nationality.

Where the inequalities show up

Inequalities in income, race, gender and cultural identity, both within and between societies, produce real disparities in access to water, food and energy:

Environmental injustice

Environmental injustice is the unequal distribution of environmental burdens and benefits, often along lines of race, class or other social factors. It includes situations where marginalised communities face more environmental hazards, or have less access to environmental goods and services.

The same pattern at two scales Burdens land on those least able to refuse them LOCAL SCALE landfills and incinerators sited near low-income neighbourhoods pollution hotspots harming poorer communities’ health no clean water, safe housing or green space Altgeld Gardens, Chicago GLOBAL SCALE resource exploitation in developing countries waste exported from richer nations to poorer ones climate impacts falling on those least able to adapt plastic waste to Southeast Asia Injustice deepens existing inequality and undermines human rights The result is worse health, wider economic gaps and less resilient communities
Read the two columns across. Each local injustice has a global counterpart driven by the same imbalance of power.

At the local level

At the global level

In general, environmental injustice increases existing social inequalities and undermines human rights, particularly for vulnerable populations. It leads to negative health outcomes, economic disparities and reduced wellbeing and resilience in affected communities.

Case study: Altgeld Gardens, Chicago

Altgeld Gardens is a predominantly African American, low-income neighbourhood on Chicago’s South Side that has faced environmental injustice for decades.

Case study: plastic waste export to Southeast Asia

Over recent decades, developed countries — particularly in Europe — have increasingly exported plastic waste to developing nations in Southeast Asia such as Malaysia, Thailand and Vietnam.

Why the “recyclable” label matters. Exporting waste labelled recyclable lets the exporting country record it as recycled in its own statistics, even when it is burned in the open on arrival. The injustice and the accounting problem are the same problem — which is why indicators, covered in the next note, have to be chosen carefully.

Applying justice at every scale

The principles of sustainability and environmental justice apply across scales, from individual decisions to national policy to global frameworks.

Action happens at every scale Individual choices and global frameworks are not alternatives INDIVIDUAL reducing waste saving energy reusable products using public transport backing local green projects NATIONAL laws and regulations planning decisions where hazards are sited the scale most injustices occur at GLOBAL the UN SDGs international agreements accountability between states SDG 13 targets climate action Everyday choices shape broader patterns of consumption But siting decisions and waste exports are settled at the other two scales
Both ends matter, and they matter differently. Personal choices shift demand; policy decides who lives next to the landfill.
You need at least one local and one global example, and you need to be able to evaluate the causes, impacts and responses critically. Beyond the two here, other usable examples are the Deepwater Horizon oil spill in the Gulf of Mexico (2010), the Union Carbide gas release in Bhopal, India (1984), and Maasai land rights in Kenya and Tanzania.

Worked examples

WE 1

Defining environmental justice

Outline what is meant by environmental justice. (3 marks)

Step 1: the right Environmental justice is the right of all people to live in a pollution-free environment and to have equitable access to natural resources. Step 2: who it applies to That right applies regardless of race, gender, socio-economic status or nationality. Step 3: what its absence looks like Environmental injustice is the unequal distribution of environmental burdens and benefits, where marginalised communities face more hazards or have less access to environmental goods. Equal right to a clean environment and fair access to resources the word “equitable” means fair and equal — use it precisely
WE 2

A local example

Using a named example, explain how environmental injustice operates at a local scale. (4 marks)

The example Altgeld Gardens is a predominantly African American, low-income neighbourhood on Chicago’s South Side. The burden A city-operated landfill, running since the 1940s, was used for municipal waste, hazardous materials and toxic industrial by-products. The impact Residents report air and water pollution, foul odours and respiratory problems linked to living close to the site. The injustice Despite protests, lawsuits and demands for closure, the site still operates as a waste transfer station, so the burden falls on a community with least power to remove it. The hazard was sited where residents had least ability to refuse it name the community, the hazard, the health impact and the failed response
WE 3

Global injustice

Explain how the export of plastic waste creates environmental injustice. (4 marks)

Step 1: the flow Developed countries, particularly in Europe, export plastic waste to developing nations in Southeast Asia such as Malaysia, Thailand and Vietnam. Step 2: the capacity problem The volume, often labelled recyclable, overwhelms local waste management infrastructure, which cannot process it responsibly. Step 3: the local impact Open burning and improper disposal cause air and water pollution and serious public health risks for nearby communities. Step 4: why it is unjust The benefits of consuming the plastic accrue in wealthy nations while the pollution and health costs fall on poorer ones, widening existing inequality. Benefits stay in one country; the burden is shipped to another separating who benefits from who suffers is the core of any justice answer
