Title: Natur als Kapital (German original); Nature as Capital (English translation)
Authors: Markus Müller & Anna Katharina Meyer
Publisher: Springer Gabler
Publication: October 2025
Sustainability topics: Sustainable Finance 💰, Nature 🌱, Corporate Sustainability 🏢, Carbon 🌫️

Müller and Meyer ask whether capitalism can learn to respect planetary boundaries and map out exactly how it could happen.

The book opens with rubble and recognition. Standing among Maya temple ruins in Mesoamerica, Markus Hans-Peter Müller confronts the stone skeleton of a civilization that collapsed under the weight of its own success. Resource depletion. Degraded soils. Environmental poisoning. 

Nature as Capital doesn't deal in doomsday predictions. What distinguishes this book is the authors' lived expertise. Müller brings years of navigating international finance; Meyer contributes deep expertise in sustainability accounting and development economics. Between them, they've spent enough time with managers and corporate and institutional leaders to know which environmental programs actually transform operations and which exist purely for stakeholder optics.

Their central provocation lives in the subtitle: Evolution or Revolution? Can we reform market capitalism to operate within ecological limits, or does survival demand tearing the whole system down and starting over? Across eight rigorous chapters spanning Earth system science, corporate governance, market design, and philosophical critique, they build a persuasive case for evolution because they've identified concrete pathways that could work.

The GDP illusion

The forensic accounting begins with a question that should disturb anyone paying attention: how did GDP become the world's dominant measure of prosperity when it systematically ignores the estimated €125 trillion in annual ecosystem services that make economic activity possible?

The math is perverse. A living forest sequesters carbon, regulates water cycles, maintains biodiversity, prevents erosion, and generates millions in value. GDP registers: zero. Cut it down for timber, and suddenly you've created "growth." This is an embedded institutional logic that structurally rewards destroying the foundations of future prosperity.

Müller and Meyer trace how this happened through post-war institutional design and conventions that treated nature as infinite. Forests, watersheds, and atmospheric stability were all assumed to be free and inexhaustible. The result: fragmented global supply chains that obscure environmental costs so thoroughly that even well-intentioned actors can't see the full impact of their decisions.

​​The solution they propose is fundamentally redesigning how information flows through them. Make ecological truth visible in prices and financial statements, and suddenly, economic logic can align with biophysical reality.

What science sees that economics misses

The arguments made are supported by facts. Humanity moves more Earth than all natural erosion processes combined. We have breached seven of the nine planetary boundaries (there was an update since the book was produced), defining safe operating space for civilization. The Great Acceleration since 1950 is a fundamental restructuring of humanity's relationship with Earth systems.

The ecosystem services catalogue reads like an inventory of civilization's life support systems: pollination services worth $235-577 billion yearly, wetlands filtering water, mangroves buffering storms, soil organisms enabling agriculture. Total estimated value: $125 trillion annually, exceeding global GDP.  Yet they appear nowhere in corporate balance sheets.

From theory to practice: frameworks that work

Here's where Nature as Capital separates itself from typical sustainability literature. The authors detail implementable solutions with the precision of engineers.

System of Environmental Economic Accounting (SEEA): Standardized UN protocols for tracking environmental assets alongside traditional economic measures at the national scale. Not theoretical, over 90 countries are implementing it.

Natural Capital Accounting: Methods helping companies quantify ecosystem dependencies and impacts in the financial language executives actually use for decisions.

Absolute Environmental Sustainability Assessment (AESA): Tools measuring whether corporate operations stay within planetary boundaries, not just whether they're "improving" relative to past damage.

The Sustainability Baseline: A simple but powerful concept, real sustainability means maintaining natural capital stocks, not just slowing their depletion.

The chapter on double materiality offers particularly actionable guidance. Companies should report both how environmental factors affect their business performance AND how their operations affect environmental systems.

In the Transformation Management Compass, Müller and Meyer talk about a roadmap for embedding ecological constraints directly into strategy, capital allocation, supply chain management, and performance metrics. Not sustainability departments churning out reports nobody reads, but planetary boundaries as hard constraints in core operations.

Markets as tools, not magic

The treatment of nature markets carbon and biodiversity credits, and habitat banking demonstrates the nuanced thinking throughout. Müller and Meyer neither dismiss these mechanisms as neoliberal commodification nor embrace them as silver bullets.

Instead, they analyze design principles determining whether markets help or harm. Well-structured systems with robust verification, transparent baselines, and real enforcement can channel capital toward regeneration. Poorly designed systems enable industrial-scale greenwashing.

Markets are governance tools that work only with continuous oversight, accountability mechanisms, and a willingness to intervene when they fail. The carbon versus biodiversity comparison illuminates both the possibilities and the permanent challenges around verification, additionality, permanence, and leakage.

Intellectual honesty about the alternatives

Chapter 7 engages seriously with Kohei Saito's revolutionary critique, arguing that capitalism's growth imperative makes ecological sustainability structurally impossible that reforms can't overcome the dynamics driving relentless accumulation regardless of planetary limits.

Rather than dismissing this, Müller and Meyer grapple with it directly before making their counter-case: revolutionary transformation faces overwhelming near-term political obstacles. Evolutionary reforms, while imperfect, offer immediate pathways for damage reduction that don't require overturning global economic systems before taking action.

This acts as strategic realism about deploying achievable interventions now while longer transformation unfolds. The synthesis of insights from indigenous knowledge systems, environmental justice frameworks, and degrowth movements enriches rather than undermines their evolutionary position.

A path that could actually work

The conclusion synthesizes their program: mandatory natural capital accounting complementing GDP, market structures that internalize ecological costs through smart regulation, governance architectures embedding planetary boundaries into corporate decision-making, financial systems redirecting capital toward regenerative activities, and prosperity metrics that supplement GDP.

This is a systematic reconstruction of economic foundations to make ecological stability definitional rather than aspirational. The "dual steering approach" they propose balances efficiency with preservation, maximizing value creation while maintaining the ecosystem functionality that makes value creation possible over time.

The concept of "nature as active capital" reframes the relationship entirely. Ecosystems are foundational infrastructure requiring investment and maintenance, like the machines companies already meticulously care for because they know neglected equipment fails.

Why you should read this now

In 2025, with ecological tipping points measurably closer and political resistance to environmental action intensifying globally, Nature as Capital offers something increasingly rare: pragmatic frameworks grounded in actual science and actual corporate governance experience.

For executives navigating mounting sustainability pressures, financial professionals integrating ESG considerations, policymakers designing environmental regulations, or business school faculty teaching beyond greenwashing basics, this book provides concrete methodologies and clear implementation pathways.

Müller and Meyer's core insight resonates because it's demonstrably true: maintaining natural capital is an economic necessity. The €125 trillion in ecosystem services aren't externalities to be "managed," but instead, they’re the foundation on which everything else rests.

Whether institutional transformation happens fast enough remains uncertain. But the authors have mapped the territory with unusual clarity. For anyone ready to move beyond sustainability theater toward genuine integration of ecological boundaries into economic decision-making, this book provides the detailed guidance that's been missing.

The Maya couldn't see their trajectory in time. We still can. Nature as Capital shows us how to use that advantage before it runs out.
