Sustainable Economic Development: Meaning and Strategies

Sustainable economic development is a model that integrates economic, social and environmental goals to maximize human well-being without compromising future generations. What does sustainable economic development mean in practice? Its main goal is to reduce absolute poverty while minimizing the degradation of natural resources, relying on strategies such as energy efficiency and renewable energy.

The debate on economic development centers on how to promote economic growth that is inclusive of both society and the environment.

The challenge is to improve the quality of life of millions of people without drastically harming the environment.

What is sustainable economic development?

There is no consensus on a single accepted definition of sustainable economic development. However, some definitions are generally accepted:

In simple terms, sustainable economic development is a model in which development integrates society’s economic, social and environmental goals in order to maximize human well-being in the present without compromising the ability (the right) of future generations to meet their own needs. This definition draws on the principle formulated by the UN Brundtland Commission in 1987, which defines sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

According to the World Conservation Strategy (1980): maintaining essential ecological processes and life-support systems, preserving genetic diversity and ensuring the sustainable utilization of species and ecosystems. In other words, it means pursuing economic development through the conservation of natural resources.

This new approach emphasizes meeting the basic needs of the poorest, bringing about cultural change and increasing community participation in development processes. But these processes must be environmentally sustainable.

Challenges of sustainable economic development

Sustainable economic development combines elements of sustainability with economic ones. This poses an enormous challenge for the various sectors of society, especially because it runs counter to the dominant economic consensus.

One of the key elements of this approach to development is cumulative causation. It explains how poor people, in trying to survive, cause extensive environmental damage that leads to losses in the short and long term. Examples include overgrazing an area with livestock, farming without letting the land rest (which causes erosion), or cutting down trees to make charcoal.

The problem is not that people’s survival is put ahead of the environment, but rather the extreme inequality and lack of opportunities that force many people to destroy the environment in order to survive.

That is why one of the direct concerns of sustainable economic development is to raise the living standards of the poorest. This can be measured quantitatively in terms of available food, real income, health and education services, sanitation and transportation, among others.

In other words, the main goal of sustainable economic development is to reduce absolute poverty, ensuring a high quality of life while minimizing the use and degradation of natural resources. This means that aggregate economic growth (GDP growth) takes a back seat. This challenge is especially relevant in cities, where there are more challenges and opportunities for achieving this kind of development.

Decoupling: can GDP grow while resource use and emissions fall?

Economic sustainability comes down to a measurable question: whether output can rise without pressure on nature rising in the same proportion. So far, growth has pulled material consumption along with it. According to the UNEP International Resource Panel (2024), global resource extraction grew from 30 billion to 106 billion tonnes since 1970, and extracting and processing those resources accounts for more than 60% of planet-warming emissions.

The mechanism follows from a simple identity: emissions = GDP × carbon intensity (tonnes of CO2 per dollar of output). If intensity falls more slowly than GDP grows, emissions keep rising: that is relative decoupling. If intensity falls faster than the economy grows, emissions decline in absolute terms while the economy expands: that is absolute decoupling, the only kind compatible with reducing total pressure. In 2024, according to the International Energy Agency (2025), global energy-related CO2 emissions rose 0.8% while GDP grew 3.2%: relative decoupling, not absolute. The European Environment Agency (2021) considers long-lasting absolute decoupling at the global scale unlikely, and notes that in the EU part of the improvement comes from moving energy-intensive activities to other countries.

Worked example: the United Kingdom, 1990–2023

World Bank data: GDP in constant 2015 dollars and CO2 excluding land use (EDGAR-based series, accessed October 2026):

GDP: from $1.72 trillion in 1990 to $3.28 trillion in 2023. Change: 3.28 ÷ 1.72 − 1 = +90.7%.
CO2: from 582.6 to 304.8 million tonnes. Change: 304.8 ÷ 582.6 − 1 = −47.7%.
Intensity: 582.6 Mt ÷ $1.72 trillion = 338 grams of CO2 per dollar in 1990; 304.8 Mt ÷ $3.28 trillion = 93 grams in 2023. Decline: −72.6%.
Conclusion: the economy nearly doubled and emissions released inside the country were almost halved: absolute decoupling on a territorial basis. The figure excludes the CO2 embedded in imports, the caveat the EEA raises.

Using the same source, the calculation for the world between 2015 and 2023 gives a different result: GDP grew 24.1% (2.7% a year) and CO2 7.8% (0.9% a year), because intensity only fell from 479 to 416 grams per dollar, or 1.7% a year. For global emissions to start falling, intensity would have to drop faster each year than the economy grows. More context on the British case in the natural resources of the United Kingdom.

Four approaches to the same dilemma

Approach	What it proposes	Relationship with resources	Limit identified by the sources
Conventional linear growth	Maximize GDP; environmental damage is treated as an externality	Take, make, and throw away	Extraction has tripled since 1970 (UNEP, 2024)
Green growth	Keep growing while natural assets continue to provide their services, driven by innovation (OECD, 2011)	Seeks to cut intensity per unit of GDP	The EEA sees long-lasting absolute decoupling at the global scale as unlikely
Circular economy	Eliminate waste, keep products and materials in use, and regenerate nature	Replace virgin raw materials with recovered materials	In the EU-27 only about 12% of the material entering the economy was recycled (2019)
Degrowth	Reduce production and consumption and set goals other than GDP growth	Cuts the total volume of materials and energy	The EEA calls it extremely challenging: growth is linked to gains in health and education, and extreme poverty fell from 36% to 10% between 1990 and 2015

Source: compiled from the EEA (2021, Table 1, which cites the OECD definition), the Ellen MacArthur Foundation, and UNEP-IRP (2024).

The four approaches are not mutually exclusive: a country can apply circular measures within a green growth strategy. What separates them is whether it is enough to cut the carbon in each dollar of output, or whether the total volume of materials and energy must also be limited.
