Clean Air, Healthy Nature, Stronger Economies: The GDP Case for Planetary Health
Investing in planetary health could unlock trillions in global GDP, reduce poverty, and save millions of lives, according to the UN’s GEO-7 report.
Introduction: The Economy’s Most Overlooked Growth Engine
For decades, economic growth and environmental protection were treated as competing priorities—one thriving only at the expense of the other. But a growing body of global evidence now tells a very different story. Investing in planetary health—clean air, stable climate systems, fertile land, thriving biodiversity, and pollution-free ecosystems—is no longer just an ethical or ecological imperative. It is fast becoming one of the most powerful drivers of long-term global economic growth.
This shift in thinking is at the heart of The Global Environment Outlook, Seventh Edition: A Future We Choose (GEO-7), released during the seventh session of the United Nations Environment Assembly (UNEA) in Nairobi. Compiled by 287 multidisciplinary scientists from 82 countries, the report presents a compelling economic argument: safeguarding the planet could unlock trillions of dollars in additional global GDP, save millions of lives, and lift hundreds of millions of people out of poverty and hunger.
Context & Background: The Rising Cost of Environmental Decline
The world is already paying a steep price for environmental neglect. Climate change, biodiversity loss, land degradation, desertification, and pollution are no longer distant threats—they are active economic drains.
According to the GEO-7 assessment, environmental damage is costing the global economy trillions of dollars every year. Extreme weather events disrupt supply chains, degraded soils reduce agricultural productivity, polluted air drives healthcare costs skyward, and biodiversity loss weakens food systems and natural disaster resilience. These impacts are cumulative, structural, and increasingly irreversible.
Air pollution alone imposed an estimated economic cost of $8.1 trillion in 2019—around 6.1 percent of global GDP—through healthcare expenses, lost productivity, and premature deaths. Meanwhile, plastic pollution has accumulated to nearly 8,000 million tonnes globally, contributing to health-related economic losses estimated at $1.5 trillion annually due to toxic chemical exposure.
Despite these staggering figures, current economic systems often fail to fully account for nature’s value. GDP growth can rise even as ecosystems collapse, masking long-term risks beneath short-term gains.
Main Developments: A Growth Model Built on Planetary Stability
The GEO-7 report offers an alternative trajectory—one rooted in whole-of-government and whole-of-society transformations across key economic systems. Instead of treating environmental protection as a cost, the report frames it as an investment with extraordinary macroeconomic returns.
Trillions in Economic Gains
Under the report’s transformation pathways, global macroeconomic benefits begin to materialize around 2050. By 2070, these benefits are projected to reach $20 trillion per year, before surging to an estimated $100 trillion annually in the decades that follow.
These gains stem from multiple reinforcing factors: reduced climate risks, healthier and more productive populations, resilient food systems, lower disaster-related losses, and restored natural capital.
Healthier People, Stronger Economies
One of the most immediate economic dividends of planetary health investment is improved public health. By cutting air pollution alone, the report estimates that nine million premature deaths could be avoided by 2050.
Healthier populations mean lower healthcare expenditures, higher workforce productivity, and longer working lives. These benefits ripple through economies, boosting consumption, savings, and investment capacity—core drivers of GDP growth.
Poverty, Hunger, and Human Development
Environmental restoration also intersects directly with social outcomes. By 2050, nearly 200 million people could be lifted out of undernourishment, while more than 100 million people could escape extreme poverty under the transformation scenarios.
Stable climates and healthy soils improve food availability and affordability. Biodiversity-rich ecosystems support livelihoods in agriculture, fisheries, and tourism—sectors that employ hundreds of millions globally, especially in developing economies.
Expert Insight and Global Consensus
The scale and scope of GEO-7 underscore a growing international consensus: environmental policy is economic policy.
Scientists involved in the report emphasize that the cost of action—estimated at around $8 trillion annually until 2050 to achieve net-zero emissions and protect biodiversity—is significant but manageable. Crucially, it is far lower than the cost of inaction.
If current trends continue, land degradation alone is expected to claim fertile, productive land equivalent in size to Colombia or Ethiopia every year. At the same time, climate change could reduce per-person food availability by 3.4 percent by mid-century, exacerbating inflation, food insecurity, and social instability.
From an economic standpoint, these losses represent missed growth, higher fiscal burdens, and increased geopolitical risk.
Sweeping Transformations Required Across Five Systems
The report identifies five interconnected systems where transformation is essential to unlock planetary and economic benefits.
1. Economy and Finance
GEO-7 calls for moving beyond GDP as the sole measure of progress, advocating inclusive wealth metrics that account for natural, human, and social capital. Pricing environmental externalities correctly—through carbon pricing, pollution taxes, and subsidy reforms—would align markets with planetary boundaries.
2. Materials and Waste
Transitioning to circular economies is central to reducing waste and resource pressure. Circular product design, transparent supply chains, and regenerative business models can significantly cut costs, create new industries, and reduce environmental damage simultaneously.
3. Energy Systems
Decarbonising energy supply while improving efficiency is foundational. The report also stresses the need for socially and environmentally responsible critical mineral supply chains, ensuring the clean energy transition does not replicate extractive injustices.
4. Food Systems
Shifting to healthier, more sustainable diets, reducing food loss and waste, and improving production efficiency can stabilize food prices, enhance nutrition, and reduce land and water stress—all with positive GDP impacts.
5. Environmental Restoration
Accelerated conservation and restoration of ecosystems, supported by nature-based solutions, strengthen climate resilience, protect biodiversity, and lower disaster recovery costs—an often-overlooked economic benefit.
Impact & Implications: Who Gains, Who Risks Falling Behind
The implications of this transformation are global but uneven. Countries that invest early in planetary health stand to gain competitive advantages in clean technologies, sustainable finance, resilient agriculture, and green infrastructure.
Conversely, economies that delay action risk being locked into high-cost, high-risk pathways marked by climate shocks, food insecurity, public health crises, and declining investor confidence.
For policymakers, the message is clear: environmental investment is no longer a discretionary expense. It is a prerequisite for sustained economic growth, fiscal stability, and social resilience in the 21st century.
Conclusion: Choosing the Future We Want
The GEO-7 report delivers a powerful, evidence-based message: the choice between economic growth and environmental protection is a false one. The real choice lies between short-term exploitation and long-term prosperity.
By investing in planetary health—clean air, stable climates, healthy ecosystems, and pollution-free environments—the world can unlock unprecedented economic gains while safeguarding human well-being. The costs are real, but the rewards are transformative.
As the report’s title suggests, A Future We Choose is not predetermined. It is shaped by the decisions made today—decisions that could define not only the health of the planet, but the prosperity of generations to come.
