ESG & Sustainability Consulting Career Guide: The Purpose-Driven Path

ESG and sustainability consulting career overview in India

Table of Contents

Climate change isn’t a distant threat anymore—it’s reshaping business strategy today. Companies face mounting pressure from investors demanding ESG (Environmental, Social, Governance) disclosures, governments enforcing carbon regulations, customers choosing sustainable brands, and employees wanting to work for responsible employers. This convergence has created one of consulting’s fastest-growing and most purpose-driven specializations: ESG and sustainability consulting.

In 2025, virtually every major company in India—from Reliance to Tata to Infosys—has committed to net-zero targets, published sustainability reports, and hired dedicated ESG teams. But most lack the expertise to measure carbon footprints, design decarbonization strategies, or navigate complex reporting frameworks. That’s where sustainability consultants come in, helping organizations transform environmental and social commitments from PR statements into measurable business strategy.cse-net+1​

This guide explores what ESG consultants actually do, the technical and business skills needed, certifications that matter, salary trends, top firms building practices, and practical paths to break into this meaningful, high-growth career—whether you’re a science graduate, engineer, MBA, or traditional consultant looking to pivot.
