Sustainable Development vs Environmental Policy: Where the “Social” Part Went

The original idea of sustainable development

By Zöe Rucker

The concept of sustainable development did not begin as an environmental policy tool. It was introduced as a framework for balancing environmental protection, economic activity and social wellbeing.

The most widely cited definition comes from the World Commission on Environment and Development’s 1987 report Our Common Future, which defined sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs¹.

From the outset, the idea was not only about protecting ecosystems. It was about ensuring that human needs — including dignity, wellbeing and equity — were met within environmental limits: boundaries beyond which environmental damage becomes difficult or impossible to reverse.

This vision is often described through the three pillars of sustainability:

• Environmental protection 

• Economic development 

• Social wellbeing

In theory, the three pillars are interdependent. Environmental protection cannot succeed without social stability, and economic growth cannot be sustainable if it increases inequality or deprivation.

In practice, however, sustainability policy developed differently.

Why clothing matters in sustainability

Clothing sits at the intersection of environmental systems and social life.

The fashion industry is frequently discussed in sustainability debates because of its environmental footprint, including resource use, textile waste and global supply chains².

Clothing also has a social function, linked to participation in everyday activities such as school, work, sport and community life.

Within sustainability indicators, clothing is typically addressed through its environmental impacts rather than as a measure of material access.

When sustainability became environmental policy

Over time, the language of sustainability gradually narrowed.

In many policy frameworks, sustainability became shorthand for environmental performance: reducing carbon emissions, managing waste and improving resource efficiency.

This shift is visible in major UK policy frameworks. Environmental indicators dominate sustainability measurement, particularly those linked to:

• climate targets

• waste reduction 

• recycling 

• resource productivity

Much of this architecture sits within departments responsible for environmental management and is assessed through climate and resource indicators³.

These are vital goals. But the social dimension of sustainability — whether people can participate fully in society — receives far less attention.

The promise of the Sustainable Development Goals

The international framework that most clearly retained the three-pillar vision is the Sustainable Development Goals (SDGs), adopted by the United Nations in 2015⁴.

The 17 goals include environmental outcomes such as climate action and responsible consumption, but also explicitly social objectives:

• ending poverty 

• reducing inequalities 

• ensuring good health and well-being 

• promoting decent work

The SDGs recognise that sustainability is not only about how resources are managed, but also about how societies function.

However, translating that broader vision into national policy has proved uneven.

The missing social dimension

In practice, sustainability reporting and policy debates often concentrate on environmental indicators.

Carbon targets are widely tracked. Recycling rates are regularly published. Waste reduction programmes are closely monitored.

Social conditions linked to everyday participation are not typically included within sustainability indicators.

Environmental metrics can track emissions and resource use, while measures of material need are captured through separate social and economic datasets. Clothing is one example.

How sustainability is applied in policy

If sustainability is defined as meeting human needs within environmental limits, its application depends on how those needs are measured within policy frameworks.

In practice, sustainability indicators are largely environmental, while measures of material need are captured through separate systems.

Clothing sits across these areas.

Understanding this distinction requires looking more closely at how sustainability is measured and what those measurements include.
