The convergence of neuromarketing and sustainable finance presents a groundbreaking opportunity to reshape consumer behavior and ethical investment practices. Neuromarketing, leveraging technologies like EEG, eye-tracking, and AI-driven analytics, provides deep insights into subconscious consumer preferences, while sustainable finance, guided by Environmental, Social, and Governance (ESG) principles, seeks to align profitability with long-term societal and environmental goals. This paper explores how emerging technologies in neuromarketing can influence sustainable finance strategies, highlighting future trends and practical case studies. It also addresses ethical concerns around data privacy and consumer manipulation, emphasizing the need for responsible integration of neuromarketing insights into sustainable finance, ultimately pointing to the potential for a new era of “neurofinance.”
