Preface
This thesis was written to highlight the inefficiencies in our current systems of consumption, production, and business. It is evident that significant changes to these systems are necessary to avoid environmental catastrophe. During my undergraduate study of finance, I was trained in methods for making financially sound business decisions but observed that the downstream and environmental impacts of corporate and industrial projects were often overlooked. This realization led me to explore sustainable business practices as a way to build truly successful businesses—those that create long-term value for society. Successful entrepreneurs understand the importance of building customer-focused businesses. Providing maximum value to customers not only generates higher returns but also fosters a stronger competitive advantage. Through this research, I have gained valuable insights into what consumers value most and how those decisions impact broader systems. This thesis represents the beginning of my efforts to develop stronger, more persuasive arguments that sustainability provides a powerful framework for addressing complex problems. Moving forward, I hope to extend these principles to explore applications in business and economic systems. The ultimate goal is to create efficient, sustainable systems that benefit humanity and allow us to live in harmony with our planet.
1.0 Introduction: Climate Change and Sustainability
The climate is changing and humans are to blame. Natural ecosystems continue to be disregarded as an integral input of our economic systems. Our economy’s primary energy sources are fossil fuels which are being extracted from Earth's core at a rate faster than they can form. These extraction and refinery practices not only remove valuable, finite, and nonrenewable resources, but are also highly inefficient as most of the material is wasted before it reaches the end use-case. A remarkable percentage (over 30%) of the resources extracted are directly discarded or mismanaged. [1] In Natural Capitalism, author Paul Hawken attempts to quantify the wastefulness of our systems based on industrial flows. Of the materials mined or harvested, 93% is lost in extraction and manufacturing, with only 7% transformed into finished products. 6% of those are discarded after one use by consumers, and only 1% remains in durable goods. [2] Waste surrounds us, and our production and consumption practices have exceeded nature’s ability to process outputs. Plastic waste, for instance, can take between 20 to 500 years to decompose, and much of it ends up in oceans polluting marine ecosystems. [3] Carbon emissions, too, persist in the atmosphere for up to 30 years before being reabsorbed into the carbon cycle. The global average CO₂ concentration now exceeds 419.3 ppm (2023), a 50% increase from pre-industrial levels. [4] Our modern economy is built on mass production and industrialization—optimized for speed, volume, and unit economics, not waste minimization or efficiency. Some firms employ strategies like planned obsolescence, where products are intentionally designed for early replacement, further escalating waste. These production systems, deeply rooted in American culture since the advent of the assembly line, influence how goods are manufactured and consumed. To fix inefficiencies, both consumption and production cycles must be addressed. As these human-centric systems become increasingly complex, so does the need to manage their shortcomings. This research explores consumer choices and sustainable decision-making—filling a gap in existing research. Consumers drive demand, shaping business behavior more than supply constraints.
1.1 Proposed Solution: Sustainability & Systems Thinking
Sustainability provides a guiding framework for responding to the climate crisis. It was first defined by the United Nations Brundtland Commission in 1987 as “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” While that definition is comprehensive and widely accepted, it is also vague and overly broad. More recent definitions have refined the concept to be more actionable. In Sustainability: What Everyone Needs to Know, Thompson and Norris offer a sharper take: “a measure of whether (or to what extent) a process or practice can continue.” [5]
This modern definition shifts the emphasis toward long-term feasibility and repeatability—what can continue and for how long. It reinforces the need to factor future viability into current decision-making. From a business or individual standpoint, this definition helps connect sustainable practice with strategic planning, as decisions must be compatible with continuity.
This thesis adopts a simple working definition: a sustainable decision is one that does not jeopardize your ability to make the same decision again in the future. In theory, the most sustainable decisions are those that can be repeated infinitely. While such perfect cases are rare, sustainability lies in the effort to maximize net benefit and minimize net cost in a way that maintains future opportunity.
Systems thinking is a critical complement to this framework. It emphasizes interconnection and feedback loops. Donella Meadows, in Thinking in Systems, argues that “the behavior of a system cannot be known just by knowing the elements of which the system is made.” [6] In other words, the structure and feedback of the system matter just as much as its components. Most human activity—including economic activity—is a subsystem of the biosphere. Nearly 30% of global economic output is macro-critically dependent on natural systems like water cycles, nutrient flows, and ecological stability. [7]
From a systems view, sustainable processes are those that produce equal or greater output with fewer inputs over time. These systems last longer, use fewer resources, and typically deliver stronger long-term value. They minimize extraction while maximizing regeneration. That is the vision of sustainability embedded in this research.
