As I look back at the semester, this practicum has both introduced me to and reshaped the way I understand sustainable investing, while also giving me hands-on experience in consulting. At the start of the course, I hoped to learn concrete examples of sustainable investing across sectors beyond my initial expertise in renewable energy. That expectation was exceeded. Through my peers’ projects and the research they conducted, I learned about sustainable approaches in the timber supply chain, insurance, government, and other sectors I had never associated with ESG or climate-aligned investing. The guest lecturers further expanded this interdisciplinary view by sharing their own stories in the field. As my understanding grew, so did my appreciation that sustainable investing is not a single methodology but an evolving set of tools, incentives, and practices. In this post, I’d like to reflect on two readings that shaped this understanding: one focused on the challenges within ESG frameworks and the other on how incentives for green production are taking form in financial markets.
The McKinsey (2022) reading argues that ESG is not simply a communications exercise or a branding strategy, but a response to rising externalities and the “social license” companies need to operate. McKinsey highlights the limits of ESG measurement, particularly the imperfect and inconsistent information available and how these limitations can lead to a gap between what investors hope to evaluate and what companies can actually report. Yet the article also emphasized why companies cannot afford to wait for perfect data: societal expectations and climate-related risks are increasing at a faster pace than the measurement frameworks needed. This insight helped me see why investors and practitioners continue to prioritize ESG integration despite critiques of inconsistency or “greenwashing.” The idea of social license, especially, reframed ESG for me as a necessary strategy for corporates rather than an optional enhancement.
The second reading, Climate Capitalists (2024), explained how financial markets translate sustainability preferences into real economic incentives. Their analysis shows that since 2016, green firms’ perceived cost of capital has fallen by about one percentage point relative to brown firms, and that this gap is large enough to influence companies’ investment decisions. This finding complemented what I’ve been learning in other classes this semester: sustainable investing does not only reward green firms symbolically; it can also materially improve portfolio resilience and long-term performance. Seeing that investments by sustainable funds have contributed to lower discount rates for green projects reinforced the idea that investor preferences can meaningfully accelerate the transition toward greener production, even in the absence of strong carbon pricing.
I’m finishing this practicum with a better understanding of what sustainable investing is, the barriers and opportunities within it, and the invaluable experience of putting my knowledge into practice.
