What Sustainable Development is Really About

I spent the better part of two years, from 2022 to 2024, pursuing a Master’s in Sustainable Development Management (MSDM) at the Jeffrey Sachs Center. It was a journey of intense learning, with subjects ranging from the financial relevance of sustainability to the complex science of the Earth’s climate system (see a video I made on this ) My goal wasn’t just to satisfy a need for continuous learning, but to fundamentally understand what sustainable development is and how it impacts me as an individual, and us as a society. And here is what I’ve discovered: Sustainable development is not all about demonizing all current development (although we have to be critical of past and current patterns of development that fail to account for environmental and social costs) . It’s also not about the UN’s Sustainable Development Goals (though they are highly related), and it’s certainly not just about protecting the environment (although that’s relevant too).

Fortunately, a classical definition already exists—one that, once you understand it, will forever change your perspective.

In the early 1980s, the world was beginning to see the damage caused by unchecked development. Environmental degradation, pollution, and resource depletion were becoming undeniable realities. In response to these growing concerns, the United Nations set up a special commission to tackle this issue. This commission was led by Gro Harlem Brundtland, the former Prime Minister of Norway, and it became known as the Brundtland Commission. The goal of the Brundtland Commission was to study the connection between economic development and environmental sustainability. After several years of research and global consultation, the Commission published a groundbreaking report in 1987 titled “Our Common Future.” Our Common Future published by the Brundtland Commission 1987 This report introduced the world to a concept that would forever change the way we think about development: sustainable development. In this report, the Commission provided the now classical definition of sustainable development, which is still widely used today. This definition and its accompanying text states that:

Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains within it two key concepts:

1. the concept of ‘needs’, in particular the essential needs of the world’s poor, to which overriding priority should be given; and
2. the idea of limitations imposed by the state of technology and social organization on the environment’s ability to meet present and future needs.

Thus the goals of economic and social development must be defined in terms of sustainability in all countries – developed or developing, market-oriented or centrally planned. Interpretations will vary, but must share certain general features and must flow from a consensus on the basic concept of sustainable development and on a broad strategic framework for achieving it. Development involves a progressive transformation of economy and society. A development path that is sustainable in a physical sense could theoretically be pursued even in a rigid social and political setting. But physical sustainability cannot be secured unless development policies pay attention to such considerations as changes in access to resources and in the distribution of costs and benefits. Even the narrow notion of physical sustainability implies a concern for social equity between generations, a concern that must logically be extended to equity within each generation.

Let’s break this definition down into its key components.

1. Generational Thinking First, this definition introduces the idea of generational thinking. It’s not enough to focus only on the needs of the current generation; we have to think about how our actions today will impact future generations. This shift in perspective was groundbreaking. It made people realize that the resources we consume now, the pollution we create, and the ecosystems we destroy will all have long-term consequences for those who come after us.

2. Present and Future Needs Second, the definition emphasizes the importance of needs, both present and future. It’s not just about what we want, but what we need—the basics like food, water, energy, and shelter. The challenge is to ensure that everyone today has access to these necessities, without depleting the resources that future generations will need. This means balancing immediate development with long-term resource management.

3. The Centrality of Balance Finally, the concept of balance is central to sustainable development. It’s about finding the middle ground between economic growth, social progress, and environmental protection. In the past, economic development often came at the expense of the environment, leading to deforestation, pollution, and loss of biodiversity. But the Brundtland Commission argued that true development must take into account the environment. Only by achieving a balance between these three elements can we create a system that’s sustainable in the long run. The Brundtland Commission made it clear that we can no longer think of development and the environment as separate issues; they are deeply interconnected. My journey has taught me that this idea of balance is sometimes overlooked. There seems to be a push to ensure that environmental considerations must take all priority at the expense of economic growth. But when we cut down trees in order to build a road, the need for that road must be considered and balanced with the need to allow the trees to continue to grow. Because not meeting the needs of the current generation is, by definition, also not sustainable development.

4. The Role of Technology I have spent a considerable amount of time thinking about the Brundtland Commission’s reference to "limitations imposed by the state of technology." To me, this is a clear indication that the commission viewed technology as a critical component of solving these challenges. The problems created by technological advancement in the 20th century, with a lack of environmental awareness, can now be managed and solved by a new wave of technological innovation. This time, we have a full understanding of the environmental impact. Our focus must be on research and development. Technologies such as Carbon Capture, Utilization, and Storage (CCUS) , non-fossil fuel energy sources like solar, hydro, and nuclear , and even the use of AI to more effectively manage energy usage , are now critical. But it’s also important to remember that technology is not an absolute fix. It operates within the planet’s finite capacity. We must also consider the idea of equity in technology development and diffusion, ensuring that the benefits of technological solutions reach all nations, particularly the poor, to truly achieve sustainable development.

The Final Word: Finding That Balance The Brundtland Commission made it clear that we can no longer think of development and the environment as separate issues; they are deeply interconnected. Before we can move forward on the merits and demerits of specific examples, we must first agree on these basic definitions and ideas. It is only through thoughtful discussion and debate on these core concepts that we can ensure that we all move as one planet. Because sadly, as recent events have demonstrated, we are not. Sustainable development Is a continuous act of navigation, a journey of finding balance that acknowledges the needs of the present without compromising the future. What do you think?
