The global energy transformation has raised the stakes for the kind of investment approaches that will not only generate competitive financial returns, but will also help achieve climate ambitions and inclusive development. Yet, integrating this profitability of such investments with sustainability poses a significant challenge facing institutional investors and policy-makers, especially in emerging markets. This paper examines how investment tactics in the projects of energy transition would be optimally approached in order to reconcile financial performance and environmental and social issues. Based on Sustainable Investment Theory, ESG-constrained Modern Portfolio Theory, Stakeholder Theory, and the Triple Bottom Line framework, a mixed-method approach that integrates a qualitative case review with a multicriteria investment evaluation model is used in the paper. Data were collected from World Bank, IEA, UNPRI, BloombergNEF, and case reports from institutions. Three illustrative cases—green hydrogen in Germany, solar auctions in India, and mini-grids in Nigeria—were compared across return on investment, carbon reduction, and social equity. The results show that blending instruments, ESG-linked instruments, and incentive compatible models have a positive impact on investment allocations when combined with regulatory consistency, aligned disclosure standards, and risk de-risking mechanisms. The research presents an integrated investment model that links ROI with ESG factors and SDG goals. It ends by also stressing the importance of scalable financing structures, strong ESG governance, and the need to track performance over the longer-term. These findings enrich the growing discussion on sustainable finance and provide policy implications for capital deployment in energy transition trajectories.
