You may have heard the term “sustainability” used a lot lately. Eco-activists, corporations, influencers, global leaders, and even everyday people are all talking about how it’s the right thing to do. But what is sustainability, and why should you care?

At its core, sustainability is the practice of “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” If it sounds pretty important, it’s because it is. Sustainability is essential to the long term survival of life on earth, and it’s something that we all need to pay attention to.

Let’s explore sustainability in depth, its environmental impact, the businesses doing their part, and the benefits of making sustainability a priority.

What Is Sustainability?

According to Investopedia, sustainability is “the ability to continuously maintain or support a process over time.” People often use the term regarding environmental protection, but it can also refer to other areas such as social equity and economic development.

Policy-focused and business-wise, sustainability is about creating practices that will allow us to meet our current needs without compromising the ability of future generations to do the same. In other words, it’s about meeting our needs in a way that doesn’t damage the planet or deplete its resources.

In addition to sustainability’s definition, four important pillars support it: environmental stewardship, social responsibility, economic viability, and human involvement, which we’ll discuss further below. When combined, these pillars work to create a sustainable future for all.

What Is Sustainable Development?

Whenever people hear about sustainable development, United Nations Sustainable Development Goals (SDGs) usually come to mind. And if you thought so, too, you’re on the right track.

The UN 1987 Brundtland Commission Report, as reported by the United Nations Educational, Scientific, and Cultural Organization (UNESCO), defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Since then, sustainable development has been the UN’s focus to balance the environment, society, and the economy.

Fast forward to 2015, all 193 UN member countries adopted the 17 Sustainable Development Goals (SDGs) for 2030. The SDGs are a set of objectives to transform our world and ensure that no one is left behind. They cover a wide range of social and economic development issues, such as poverty, hunger, and gender equality, while also considering climate change and preserving the Earth’s forests and oceans.

All member States, regardless of their size, resources, or level of development, are responsible for meeting these goals. And since the SDGs act as a blueprint for a better and more sustainable future, each nation is allowed to devise its unique plan to achieve them – as long as they remain committed to the 2030 Agenda.

Principles of Sustainability

The three main sustainability goals are to protect the environment, foster social equity, and promote economic prosperity. Therefore, sustainable development is based on three fundamental principles to achieve these goals: environment, society, and economy. These principles are also known as the triple bottom line or planet, people, and profit.

1. Environmental Principle

The environmental principle of sustainability focuses on protecting life on earth, in all its forms. It involves reducing our reliance on fossil fuels and taking action to mitigate climate change, conserving natural resources, and cutting back on the dumping of harmful waste into the sea, air, and land. We need to move towards renewable energy sources, adopt green technologies, and promote sustainable practices, such as moving to a circular economy, to achieve this.

2.  Social Principle

The social principle of sustainability focuses on fostering social equity. Approaching this entails providing everyone with the opportunity to live a healthy and fulfilling life, regardless of their circumstances. This involves reducing poverty, ensuring all children have access to education and cutting exploitation.

3. Economic Principle

The economic principle of sustainability focuses on promoting economic prosperity. Implementing this principle requires creating jobs and promoting economic growth while protecting the environment and fostering social equity. Ensuring that everyone can earn a living wage and creating jobs in the circular economy contribute to this.

These three principles are interconnected and interdependent. To build a sustainable future, we need to address all three simultaneously. If not, we risk jeopardizing the progress we’ve made in one area while trying to improve another.

Four Pillars of Sustainability

The three principles of sustainability are often referred to as the three pillars of sustainability. But there is a fourth pillar that is just as important: humans. To achieve sustainable development, we need to protect the environment, foster social equity, promote economic prosperity, and build a resilient future.

1. Human Sustainability

Human sustainability is about protecting the health and wellbeing of people worldwide. It involves promoting nutrition, education, health care, and social services. It also entails protecting human rights and ensuring equal access to essential services, natural resources, and all forms of development.

In terms of corporate social responsibility, human sustainability is about creating value for all stakeholders. The latter includes employees, customers, suppliers, shareholders, and the communities in which businesses operate. In other words, human sustainability also focuses on an organization’s human capital as its most important asset.

On the same note, human sustainability also looks at the impact of business on society. It assesses how interactions affect the environment, social equity, and economic prosperity. As such, human sustainability requires firms to adopt environmentally friendly, socially responsible, and economically sound practices.

2. Economic Sustainability

Economic sustainability emphasizes the need to protect the environment and conserve natural resources while promoting economic prosperity. It aims to find a balance between environmental protection and an enhanced standard of living. It’s also about securing capital for future generations.

Critics, however, say that this approach to sustainability is too narrowly focused on economic growth. They argue that it overlooks the need to address social and environmental issues. In response to this, proponents of economic sustainability have developed new economic concepts, inclusive of two critical factors.

The first element is natural capital, which refers to the ecological systems that provide services essential for human survival and wellbeing. The second is social capital, which comprises the relationships amongst people. Both of these factors take a more holistic approach to economic growth.

3. Social Sustainability

Social sustainability takes on a deeper focus on people and relationships. It promotes social cohesion and inclusivity to include all community members, regardless of race, color or creed. It also strives to balance different social groups, cultures, and globalization.

Mechanisms for social sustainability generate opportunities for dialogue and collaboration to address social issues. They also develop policies, laws, and regulations to protect the rights of all individuals. The United Nations 17 Sustainable Development Goals are an example of this.

4. Environmental Sustainability

Environmental sustainability is about conserving the planet’s natural resources and protecting the environment. It involves preventing the pollution of air, water, and land. It also entails protecting endangered species and their habitats. In addition, environmental sustainability advocates for the efficient use of resources to minimize pollution and waste.

Organizations that adopt environmental sustainability measures reduce their carbon footprint and minimize their ecological impact. Since many businesses have realized that environmental sustainability is good for the bottom line, others have started generating sustainable business models that increase profits and market share.

What Is Corporate Sustainability?

The concept of corporate sustainability came from the Brundtland Commission’s definition of sustainable development above. It’s about businesses taking responsibility for their impact on the environment and society.

Its premise revolves around businesses addressing the immediate needs of their stakeholders and consumers while also investing in long-term solutions. It requires reducing their reliance on natural resources, spending on renewable energy, and promoting social and economic inclusion.

Why Is Sustainability Important?

Sustainability is vital for several reasons. First, it’s necessary for the long-term survival of humans and other species on our planet. Second, it may help businesses become more profitable and efficient. Third, it contributes to social inclusion and cohesion. Finally, it’s an essential part of protecting the environment.

Some numbers by the United Nations to think about:

  • We need approximately three planets’ combined natural resources to sustain the lifestyle of the estimated global population of 9.6 billion people come 2050.
  • People waste an overwhelming amount of food produced globally due to poor handling, transport, and storage practices – around 1/3 of all food, or 1.3 billion tonnes, worth roughly $1 trillion.
  • We can save as much as $120 billion yearly by using energy-efficient light bulbs.

These are only a few examples, but they show sustainability’s importance for present and future generations.

Why Is Sustainable Use of Natural Resources Important?

As of 2022, more than 1 billion people can’t access clean water, and 3 billion can’t access acceptable sanitation. Likewise, more than 940 million people still don’t have access to electricity, and 50 billion tonnes of carbon dioxide pollute the air every year.

All of these problems suggest a significant burden on the environment. To put it simply, we’re using up Earth’s resources faster than we replenish them. And at the rate that we’re going, nations still lag – most with their natural resources being consumed unsustainably.

Thus, the sustainability of natural resources is vital for preserving the environment, human civilization, and the economy. It’s a way to ensure that we don’t deplete the Earth of its resources and that we don’t destroy the environment.

Why Is Environmental Sustainability Important?

If summer feels like it’s getting hotter, it’s not just you. The Earth has broken heat records left and right over the past few decades. The Arctic has warmed the most – by more than 4 degrees Fahrenheit since the 1960s. And since 1880, the average global temperature has increased by 2.2 degrees Fahrenheit, or 1.2 degrees Celsius.

We can expect this trend to continue as greenhouse gasses accumulate in the atmosphere and trap more heat from the sun. And it’s not just the temperature that we have to worry about. Climate change has led to extreme weather events, like hurricanes, floods, and droughts. It’s also causing the sea level to rise as ice melts and ocean water expands.

Environmental sustainability is important because it’s necessary for the survival of humans and the planet. It’s also a pathway for businesses to become more profitable and efficient. And finally, it contributes to social inclusion and cohesion.

How Sustainability Works

Sustainability works by reducing our reliance on natural resources, investing in renewable energy, reducing waste, and promoting social and economic inclusion. When businesses adopt sustainable practices, they’re investing in the long-term health of their employees, customers, and the environment. The same goes for individuals who choose to live a responsible lifestyle.

But sustainability isn’t just about doing things differently – it’s also about doing things better. Sustainable practices often lead to improved efficiency and profitability. That’s because they help businesses eliminate waste, conserve energy, and improve their reputation.

Sustainability also operates on a larger scale. It’s about creating systemic change that leads to a healthier planet and a more just society. We need to shift the way we think about the economy, development, and progress and move away from an extractive mindset and toward one that is regenerative and restorative.

How to Achieve Sustainability

Achieving sustainability requires a three-pronged approach:

1. Reducing our reliance on natural resources:

Using less water, generating less waste, and consuming less energy.

2. Investing in renewable energy:

Utilizing solar, wind, and hydropower.

3. Promoting social and economic inclusion:

Ensuring that everyone has the opportunity to participate in the economy and enjoy a good quality of life.

We can protect the planet and its resources for future generations by taking these steps.

Challenges of Sustainability

The challenges of sustainability are numerous and complex. They include everything from climate change and dwindling resources to poverty and social inequality. Some of the most pressing challenges include:

Climate Change

One of the biggest threats to the environment. Greenhouse gasses such as carbon dioxide and methane trap heat from the sun, causing the Earth’s temperature to rise. It leads to extreme weather events, rising sea levels, and other problems.

Dwindling Resources

The world’s population is growing, and we’re using up natural resources faster than we can replenish them – from water and forests to minerals and oil.


Nearly half of the world’s population lives in poverty, without access to basic needs like food, shelter, and healthcare. The lack of economic opportunity and social inclusion compounds this problem.

Social Inequality

There’s a large gap between the rich and the poor, both within countries and across the globe. Because of this, there’s social unrest and even more strain on the planet’s resources.

The good news is that sustainability is possible. It will require a concerted effort from businesses, governments, and individuals to make it happen. But the rewards will be more than worth it. A sustainable future is a bright future for us and the planet.
