Learning to Work Within Uncertainty

As a newcomer to both sustainability and finance, I did not enter this practicum with strong convictions about sustainable finance. I had some exposure to the jargon and a general sense of the frameworks, but I had not examined how any of it worked in practice. Of course, capital should account for environmental and social externalities, especially in emerging economies. That part seemed obvious. Beyond that, sustainable finance felt abstract. It lived in models and presentations, not in real places. 

With an undergraduate degree in mathematics, I tend to approach problems structurally. I look for constraints and incentive misalignment. I try to identify the variable that explains the system. On paper, systems can look clean. But in practice, much of the work operates under uncertainty. Data is incomplete. Assumptions are rough. Estimates sit within wide confidence intervals. Even the definition of “research” spans a spectrum, from formal datasets to interviews, local knowledge, and partial documentation. That mess is not just methodological. It affects outcomes. 

I first understood that gap between model and reality in the culinary world. Working in kitchens, decisions had immediate consequences. A missed delivery or coordination failure did not stay theoretical. It showed up on the plate, and someone absorbed the cost. Development systems feel similar. When traceability fails or institutions are weak, it is not just an academic flaw. It shapes livelihoods and environmental incentives. 

Like many policy students, I carry a certain optimism. Some might call it naïve. I believe better structures can reduce inequality. I assumed that if capital were directed properly, many high-impact sectors in emerging economies could scale. This practicum has started to complicate that assumption. 

Our early research into the timber supply chain in the Brazilian Amazon has made the institutional constraints visible. Traceability gaps, especially under new EU deforestation regulations, limit producers’ ability to access higher-value export markets. Without credible verification systems, producers cannot demonstrate compliance. Without compliance, they 

remain in lower-margin segments of the supply chain. Value-added activities occur elsewhere. Local communities capture little of the benefit. 

In that setting, capital does not eliminate uncertainty. It responds to it. It prices risk, demands guarantees, or withdraws when volatility is too high. Sustainable finance does not operate in a controlled environment. It operates inside systems that are uneven, under-documented, and often unstable. 

I am still new to this field. But I am beginning to see that sustainable investing is less about elegant alignment and more about operating within constraint and uncertainty. The real question may not be how to mobilize capital in theory, but how to engage with messy systems where information is imperfect, and consequences are real. 

The work feels less abstract now. It feels grounded in uncertainty and tied to real people and environments.
