What is sustainability?

Sustainability means meeting our own needs without compromising the ability of future generations to meet their own needs. In addition to natural resources, we also need social and economic resources. Sustainability is not just environmentalism. Embedded in most definitions of sustainability we also find concerns for social equity and economic development.
Where does the term come from? While the concept of sustainability is a relatively new idea, the movement as a whole has roots in social justice, conservationism, internationalism and other past movements with rich histories. By the end of the twentieth centuries, many of these ideas had come together in the call for ‘sustainable development.’

Did you know?

Adopting sustainable practices, whether large or small, can have significant impacts in the long run. If every office worker in the United Kingdom used one less staple a day by using a reusable paper clip, 120 tonnes of steel would be saved in one year


The Bruntdland Commission

The Bruntdland Commission In 1983, the United Nations tapped former Norwegian prime minister Gro Harlem Brundtland to run the new World Commission on Environment and Development1 . After decades of effort to raise living standards through industrialization, many countries were still dealing with extreme poverty. It seemed that economic development at the cost of ecological health and social equity did not lead to long-lasting prosperity. It was clear that the world needed to find a way to harmonize ecology with prosperity. After four years, the “Brundtland Commission” released its final report, Our Common Future. It famously defines sustainable development as: development that meets the needs of the present without compromising the ability of future generations to meet their own needs.1 The Commission successfully unified environmentalism with social and economic concerns on the world’s development agenda. Sustainability is a holistic approach that considers ecological, social and economic dimensions, recognizing that all must be considered together to find lasting prosperity.

Three pillars of sustainability. What would a sustainable world look like?



Environmental Sustainability 

Ecological integrity is maintained, all of earth’s environmental systems are kept in balance while natural resources within them are consumed by humans at a rate where they are able to replenish themselves.

Economic Sustainability

Human communities across the globe are able to maintain their independence and have access to the resources that they require, financial and other, to meet their needs. Economic systems are intact and activities are available to everyone, such as secure sources of livelihood.

Social Sustainability

Universal human rights and basic necessities are attainable by all people, who have access to enough resources in order to keep their families and communities healthy and secure. Healthy communities have just leaders who ensure personal, labour and cultural rights are respected and all people are protected from discrimination.

Why sustainability?

The motivations behind sustainability are often complex, personal and diverse. It is unrealistic to create a list of reasons why so many individuals, groups and communities are working towards this goal. Yet, for most people, sustainability comes down to the kind of future we are leaving for the next generation. Sustainability as a value is shared by many individuals and organizations who demonstrate this value in their policies, everyday activities and behaviours. Individuals have played a major role in developing our current environmental and social circumstances. The people of today along with future generations must create solutions and adapt.
