What is Sustainability? Understanding the Concept

In recent years, the term "sustainability" has become more than just an environmental buzzword. It's a principle that's infiltrating lifestyles, guiding corporate ethics, and shaping government policies.

But what is sustainability, exactly??

A widely referenced definition comes from the United Nations Brundtland Commission:

?“meeting the needs of the present without compromising the ability of future generations to meet their own needs.”?

Today, there are almost 140 developing countries in the world seeking ways of meeting their development needs, but with the increasing threat of climate change, concrete efforts must be made to ensure development today does not negatively affect future generations.

This enduring concept encompasses a variety of practices and ideals that aim to create a balanced ecosystem that can stand the test of time. Let's delve deeper into the nuances of sustainability and explore why it matters to us all.

Understanding Sustainability: The Three Pillars:

At the heart of sustainability lie three interlocking pillars:?

  1. Economic?
  2. Environmental?
  3. Social?

A sustainable approach means considering the economic impact while safeguarding the environment and ensuring social equity. In practice, this can mean creating products that can be recycled, ensuring fair labor practices, and making long-term financial decisions that don't deplete natural resources.

Economic Sustainability

While conservation efforts are critical, economic sustainability is equally important. This aspect focuses on creating economic value through methods that do not deplete the Earth's resources. Sustainable businesses might invest in renewable energy not just because it's environmentally responsible, but also because it is economically viable in the long run. Economic sustainability can lead to job creation, innovation, and prosperity without causing ecological damage.

Environmental Sustainability

Central to sustainability is environmental stewardship. It's about conserving natural resources, protecting ecosystems, and reducing pollution and waste. This could involve everything from using renewable energy sources and preserving biodiversity to implementing energy-efficient practices in homes and businesses. Environmental sustainability aims to maintain the health of the planet that sustains all forms of life.

Social Sustainability

Social sustainability might be the broadest pillar, as it encompasses human rights, labor rights, and community development. It focuses on maintaining the well-being of individuals within society. This means working towards education accessibility, healthcare, diversity, gender equality, and a generally improved quality of life. When a society is socially sustainable, it can grow and evolve while caring for all its members.

Measuring the three pillars of sustainability: The Triple Bottom Line

The triple bottom line is a business principle that emphasizes the importance of companies assessing not only their financial results but also their social and environmental effects.?

This approach encourages firms to prioritize measuring their impact on society and the environment alongside their profit making goals, instead of solely concentrating on financial gains.

The triple bottom line can be broken down into “three P's”:?

  1. Profit > Economic
  2. Planet > Environmental
  3. People > Social

Firms can use these categories to conceptualize their environmental responsibility and determine any negative social impacts to which they might be contributing.

How We Can Achieve Sustainability:

Individual Action

Every one of us can contribute to sustainability in our daily lives. This may include reducing our carbon footprint by walking or cycling instead of driving, recycling and composting waste, conserving water, and being conscious consumers. Even small changes, when multiplied across millions of people, can have a significant impact.

Corporate Responsibility

Companies have a huge role to play in sustainability. This involves not only eco-friendly business practices but also ensuring ethical supply chains and fair treatment of workers. Transparency and corporate social responsibility can build trust with consumers and lead to a more loyal customer base.

Government Policies

Governments can pave the way for sustainability through legislation and policies. Subsidies for renewable energy, conservation efforts, and regulations that limit pollution are some ways that public policy can help achieve sustainability goals.


Sustainability isn't an endpoint—it's a journey. It's about finding a balance between consumption and conservation, innovation and tradition, the immediate needs and the long-term outlook. The beauty of sustainability is that it is all-encompassing and inclusive; it benefits the environment, the economy, and society. It’s a multifaceted approach to living that ensures a flourishing world for decades to come.


As proponents of sustainability, we must continue to educate, innovate, and advocate for a planet where every aspect of life is harmonious and future-proof. Our actions today will shape the world of tomorrow, making the pursuit of sustainability not just important but imperative for us all.
