Abstract:

This article explores the pivotal role of open-source projects in advancing sustainable finance, a field dedicated to aligning financial practices with environmental, social, and governance (ESG) factors. It provides a detailed overview of prominent open-source tools that facilitate climate-aligned investments, carbon footprint measurement, and data-driven risk management. By examining projects like PACTA, SBTi's Temperature Alignment Tool, Cloud Carbon Footprint, and blockchain-based carbon accounting initiatives, the article highlights how open-source platforms enhance transparency, inclusivity, and adaptability in sustainable finance. These tools empower financial institutions, policymakers, and developers to collaboratively address climate challenges, fostering a resilient and accountable financial ecosystem that supports global sustainability goals.
