Handbook of SustainableFinance ArXiv ID: ssrn-4277875 “View on arXiv” Authors: Unknown Abstract This handbook in Sustainable Finance corresponds to the lecture notes of the course given at University Paris-Saclay, ENSAE and Sorbonne University. It covers t Keywords: Sustainable Finance, ESG, Climate Risk, Green Bonds, Multi-Asset Complexity vs Empirical Score Math Complexity: 4.0/10 Empirical Rigor: 3.0/10 Quadrant: Philosophers Why: The handbook provides comprehensive definitions, historical context, and regulatory frameworks of sustainable finance with moderate mathematical modeling (portfolio theory, scoring methods) but lacks explicit backtests, code implementations, or performance metrics, positioning it as a theoretical and policy-oriented text rather than an empirical trading strategy. flowchart TD A["Research Goal: Define Sustainable Finance Frameworks & Metrics"] --> B{"Data & Inputs"} B --> C["Methodology: ESG Integration & Climate Risk Modeling"] B --> D["Data: ESG Ratings, Climate Data, Multi-Asset Returns"] C & D --> E{"Computational Processes"} E --> F["Analysis: Green Bond Valuation & Portfolio Optimization"] F --> G["Key Outcomes: Risk-Adjusted Returns & Impact Metrics"]

Hedging carbon risk with a network approach ArXiv ID: 2311.12450 “View on arXiv” Authors: Unknown Abstract Sustainable investing refers to the integration of environmental and social aspects in investors’ decisions. We propose a novel methodology based on the Triangulated Maximally Filtered Graph and node2vec algorithms to construct an hedging portfolio for climate risk, represented by various risk factors, among which the CO2 and the ESG ones. The CO2 factor is strongly correlated consistently over time with the Utility sector, which is the most carbon intensive in the S&P 500 index. Conversely, identifying a group of sectors linked to the ESG factor proves challenging. As a consequence, while it is possible to obtain an efficient hedging portfolio strategy with our methodology for the carbon factor, the same cannot be achieved for the ESG one. The ESG scores appears to be an indicator too broadly defined for market applications. These results support the idea that bank capital requirements should take into account carbon risk. ...

Green portfolio optimization: A scenario analysis and stress testing based novel approach for sustainable investing in the paradigm Indian markets ArXiv ID: 2305.16712 “View on arXiv” Authors: Unknown Abstract In this article, we present a novel approach for the construction of an environment-friendly green portfolio using the ESG ratings, and application of the modern portfolio theory to present what we call as the ``green efficient frontier’’ (wherein the environmental score is included as a third dimension to the traditional mean-variance framework). Based on the prevailing action levels and policies, as well as additional market information, scenario analyses and stress testing are conducted to anticipate the future performance of the green portfolio in varying circumstances. The performance of the green portfolio is evaluated against the market returns in order to highlight the importance of sustainable investing and recognizing climate risk as a significant risk factor in financial analysis. ...

Corporate Climate Risk: Measurements and Responses ArXiv ID: ssrn-3508497 “View on arXiv” Authors: Unknown Abstract This paper conducts a textual analysis of earnings call transcripts to quantify climate risk exposure at the firm level. We construct dictionaries that measure Keywords: Climate Risk, Textual Analysis, Earnings Calls, Environmental Exposure, Corporate Equities Complexity vs Empirical Score Math Complexity: 4.0/10 Empirical Rigor: 6.0/10 Quadrant: Street Traders Why: The research focuses on textual analysis and dictionary construction with relatively basic statistical measures, placing it in low-to-moderate math complexity. However, the use of earnings call transcripts, firm-level quantification, and likely implementation of text mining tools suggests a data-heavy, backtest-ready approach suited for practical trading or risk management. flowchart TD A["Research Goal<br>Quantify firm-level climate risk"] --> B["Data Source<br>Earnings Call Transcripts"] B --> C["Methodology<br>Textual Analysis & Dictionary Construction"] C --> D["Computational Process<br>Measure Risk Exposure Scores"] D --> E{"Key Outcomes"} E --> F["Climate Risk Quantified<br>at Firm Level"] E --> G["Discriminates between<br>Physical & Transition Risks"]
