The four pillars of sustainability

Introducing the four pillars of sustainability; Human, Social, Economic and Environmental.

The term sustainability is broadly used to indicate programs, initiatives and actions aimed at the preservation of a particular resource. However, it actually refers to four distinct areas: human, social, economic and environmental – known as the four pillars of sustainability.

Human sustainability aims to maintain and improve the human capital in society. Investments in the health and education systems, access to services, nutrition, knowledge and skills are all programs under the umbrella of human sustainability. 

Social sustainability aims to preserve social capital by investing and creating services that constitute the framework of our society. It means to preserve future generations and to acknowledge that what we do can have an impact on others and on the world.

Economic sustainability aims to maintain the capital intact. It refers to the efficient use of assets to maintain company profitability over time.

A more recent approach to economics acknowledges the limited incorporation of the ecological and social components in this model. New economics is inclusive of natural capital (ecological systems) and social capital (relationships amongst people).

Environmental sustainability aims to improve human welfare through the protection of natural capital (e.g. land, air, water, minerals etc.). Initiatives and programs are defined as environmentally sustainable when they ensure that the needs of the population are met without the risk of compromising the needs of future generations.
