In its broadest sense, sustainability is the capacity to constantly maintain or support a process over time. In business and policy contexts, sustainability aims to prevent the depletion of natural or physical resources so that they can be used indefinitely. As a result, sustainable policies underline the long-term impact of any given policy or business practice on humans, ecosystems, and the economy as a whole. The concept frequently corresponds to the belief that unless major changes are made to the way the planet is managed, it will suffer irreversible damage.
Sustainability is frequently divided into three pillars: economic, environmental, and social—also known colloquially as profits, planet, and people.

Economic Sustainability

Economic sustainability refers to practices that promote long-term economic growth while not negatively impacting the community's social, environmental, and cultural aspects.

Environmental Sustainability

The concept of "environmental sustainability" places more emphasis on the life support systems, such as the atmosphere or soil, that must be preserved in order for economic production or human life to occur.

Corporate & Social Sustainability

In business, sustainability refers to more than just environmental concerns. According to Harvard Business School, there are two ways to measure sustainable business practices: the impact a company has on the environment and the impact a company has on humanity, with the goal of creating a positive effect on at least one of those areas. Social sustainability, on the other hand, focuses on the human consequences of economic systems and includes efforts to eradicate poverty and hunger as well as combat inequality.
