India stands at a transformative moment in its corporate sustainability journey. Environmental, Social, and Governance considerations have evolved from peripheral corporate social responsibility activities into core strategic imperatives that shape investor decisions, regulatory compliance, and competitive positioning. The Business Responsibility and Sustainability Reporting framework, mandated by the Securities and Exchange Board of India, now requires the top one thousand listed companies to provide detailed, quantifiable sustainability disclosures aligned with internationally recognized standards. This regulatory revolution has created unprecedented demand for specialized ESG consulting expertise, positioning India as one of the world’s fastest-growing markets for sustainability advisory services.
The global ESG consulting market exceeded fourteen billion dollars in 2023 and continues expanding at double-digit annual growth rates as corporations worldwide grapple with increasingly complex sustainability requirements. India represents a particularly dynamic segment of this market, driven by mandatory BRSR reporting, rising foreign institutional investor scrutiny of ESG performance, and growing domestic awareness that sustainable business practices directly correlate with long-term value creation. Indian companies now recognize that robust ESG strategies enhance access to capital markets, strengthen supply chain resilience, attract talent, and protect corporate reputation in an era where stakeholders demand accountability across environmental stewardship, social responsibility, and governance ethics.
1. Deloitte: Technology-Driven ESG Transformation
Deloitte stands as the largest of the Big Four accounting and consulting firms by both revenue and employee count, with operations spanning over one hundred fifty countries and deep expertise in ESG advisory services. Deloitte’s approach to environmental, social, and governance consulting emphasizes integration of sustainability considerations into core business strategy, risk management frameworks, and operational processes rather than treating ESG as a standalone compliance exercise.
The firm’s ESG practice in India helps clients navigate the Business Responsibility and Sustainability Reporting requirements while simultaneously addressing international frameworks including the Corporate Sustainability Reporting Directive applicable to European operations, SEC climate disclosure rules affecting US-listed entities, and the International Sustainability Standards Board’s IFRS S1 and S2 standards increasingly adopted globally. This multi-framework expertise proves particularly valuable for Indian multinational corporations that must satisfy diverse regulatory requirements across jurisdictions where they operate or raise capital.
Deloitte distinguishes itself through emphasis on technology enablement and data analytics within ESG consulting. The firm develops ESG data management platforms that centralize sustainability information from disparate business units and geographies, automate calculations aligned with various reporting frameworks, and maintain audit trails supporting assurance requirements. These digital solutions address one of the most persistent challenges companies face in implementing BRSR Core reporting, which is building robust data governance ensuring every disclosed metric traces back to source records and can withstand auditor scrutiny.
In India specifically, Deloitte has published extensive research on ESG preparedness among Indian corporations, finding that eighty-eight percent of organizations believe sustainability regulations will directly impact their businesses while sixty-eight percent have formally integrated ESG strategies into operations. This research informs the firm’s consulting approach, which acknowledges that Indian companies face unique challenges balancing development priorities with environmental stewardship, managing complex supply chains with varying ESG maturity levels, and accessing the technical expertise needed to measure and reduce environmental impacts systematically.
Deloitte’s climate and sustainability services encompass greenhouse gas inventorization following internationally recognized protocols, development of science-based emissions reduction targets aligned with limiting global temperature increase to 1.5 degrees Celsius, transition planning for achieving net-zero emissions including renewable energy procurement strategies, climate risk assessment examining physical and transition risks across value chains, and advisory on green finance instruments including sustainability-linked loans and green bonds that reward ESG performance improvements.

These digital tools deploy in clients’ private cloud environments or PwC’s secure managed cloud infrastructure, providing capabilities for multi-framework compliance where a single data collection effort supports reporting aligned with Global Reporting Initiative, Sustainability Accounting Standards Board, BRSR, and International Integrated Reporting Council simultaneously. This approach reduces the reporting burden companies experience when stakeholders demand information formatted according to different frameworks.
The firm’s ESG strategy consulting helps clients identify material sustainability issues through stakeholder engagement and peer benchmarking, develop ambitious but achievable targets aligned with scientific evidence and stakeholder expectations, design governance structures ensuring board oversight of sustainability performance, integrate ESG considerations into risk management and internal controls, and establish key performance indicators linking sustainability goals to operational metrics.

Climate risk assessment represents a growing area of EY’s ESG practice, helping Indian companies understand how physical climate impacts including changing precipitation patterns, extreme weather events, and temperature increases affect operations and value chains, while also evaluating transition risks associated with policy changes, technological disruption, market shifts toward low-carbon products, and reputational consequences of inadequate climate action. These assessments inform strategic planning, helping companies build resilience against climate-related disruptions while positioning themselves to capture opportunities in the transition to sustainable economies.
4. KPMG India: Risk-Focused ESG Advisory
KPMG India positions its ESG consulting services within the broader context of enterprise risk management, emphasizing that environmental and social issues represent material business risks requiring the same rigorous assessment, monitoring, and mitigation as financial, operational, and strategic risks. This risk-centric perspective appeals to boards and senior executives who increasingly recognize that inadequate ESG performance exposes companies to regulatory sanctions, investor divestment, supply chain disruptions, talent retention challenges, and reputational damage.
The firm’s ESG advisory services include comprehensive risk assessments examining environmental compliance across operations, social risks in workforce management and community relations, governance vulnerabilities in board composition and executive compensation, third-party risks from suppliers and business partners with poor ESG practices, and climate-related financial risks affecting asset values and business models.

KPMG’s capabilities in ESG assurance distinguish the firm within India’s consulting landscape. As BRSR Core assurance requirements phase in across the top one thousand listed companies through fiscal year 2026-27, demand for independent verification services is surging.

The firm’s global assurance practice has developed specialized expertise in greenhouse gas verification, water footprint validation, social metrics authentication, and governance disclosure review.
Technology plays a central role in KPMG’s ESG service delivery. The firm leverages data analytics to benchmark client ESG performance against industry peers, identify improvement opportunities, and track progress toward targets. Artificial intelligence applications help analyze unstructured data from sustainability reports, news sources, and social media to assess ESG risks and stakeholder sentiment.

The firm’s ESG consulting in India addresses multiple dimensions including net-zero transition strategy for companies setting science-based emissions reduction targets, sustainable operations transformation reducing environmental footprints while improving efficiency, green growth strategy identifying market opportunities in sustainable products and services, ESG-driven M&A where sustainability considerations influence deal sourcing and valuation, and organizational transformation building the capabilities and culture required for sustainable business practices.
McKinsey distinguishes itself through proprietary research and analytical frameworks that quantify the business case for sustainability investments. The firm’s analysis demonstrates that companies with strong ESG performance achieve higher valuations, lower cost of capital, superior operational performance, and greater resilience during economic downturns compared to peers with weaker sustainability credentials. This evidence-based approach helps overcome skepticism among executives who view sustainability as compliance burden rather than strategic opportunity.
The firm’s sector expertise enables nuanced advisory recognizing that sustainability transformation pathways differ fundamentally across industries. Energy companies require advisory on renewable energy investment, hydrogen economy opportunities, and managing declining fossil fuel demand. Automotive manufacturers need strategy for electric vehicle transition and circular economy applications in vehicle design. Food and agriculture businesses focus on regenerative farming, supply chain traceability, and nutrition security. McKinsey’s consultants combine sustainability knowledge with deep sector understanding, delivering recommendations grounded in industry economics and competitive dynamics.

The firm’s experience working with diverse Indian industries including manufacturing, construction, real estate, hospitality, healthcare, and education enables sector-relevant advisory that addresses specific challenges and opportunities.

The firm’s emphasis on making ESG accessible to smaller organizations addresses a critical gap in India’s sustainability consulting market. While large corporations can afford premium advisory from Big Four firms and top-tier consultancies, small and medium enterprises often lack resources for extensive sustainability programs. Sambodhi’s approach recognizes that these businesses still face ESG expectations from customers, investors, and regulators while operating with constrained budgets and limited internal sustainability expertise.
With over fifteen years of experience and more than two hundred client partnerships, Sambodhi has developed practical methodologies that deliver credible ESG outcomes without overwhelming organizational capacity. The firm’s consultants understand Indian business realities, designing programs that work within resource constraints while still achieving meaningful sustainability improvements and transparent reporting.
Choosing the Right ESG Consulting Partner
Selecting an appropriate ESG consulting firm requires careful consideration of multiple factors aligned with organizational circumstances, objectives, and constraints. Company size and complexity significantly influence optimal partner choice, as large multinational corporations typically benefit from Big Four firms or top-tier consultancies with global capabilities, while mid-market companies and family businesses may find specialized or regional consultants more suitable to their scale and budget.
Industry-specific expertise matters considerably given that material ESG issues vary substantially across sectors. Manufacturing companies need consultants understanding emissions reduction technologies, water efficiency systems, and waste management innovations. Financial services require advisory on climate risk integration into lending and investment decisions. Consumer goods companies benefit from expertise in sustainable supply chains and circular economy applications. Prospective clients should evaluate consultants’ demonstrated experience in their specific industry when making selection decisions.
Scope of services required determines appropriate consultant profiles. Companies needing comprehensive ESG transformation encompassing strategy development, operational changes, reporting systems, and stakeholder engagement typically engage full-service consultancies. Organizations seeking point solutions for specific challenges like carbon footprinting or BRSR report preparation may prefer specialized boutique firms with deep technical expertise in narrow domains.
Budget considerations inevitably influence consultant selection, as premium global consultancies command higher fees than regional firms or specialized boutiques. However, clients should evaluate total value rather than hourly rates alone, considering factors including project timelines, quality of deliverables, likelihood of achieving desired outcomes, and strategic insights beyond immediate engagement scope. Sometimes higher-priced consultants deliver superior results faster, ultimately providing better return on consulting investment.
Cultural fit and relationship compatibility warrant attention given that effective ESG transformation requires sustained collaboration between consultants and client teams. Organizations should assess whether prospective consultants demonstrate understanding of company culture, respect for existing capabilities, willingness to transfer knowledge rather than creating dependency, and alignment with sustainability values beyond commercial considerations.
The Future of ESG Consulting in India
India’s ESG consulting market shows no signs of slowing down as regulatory requirements continue expanding, investor scrutiny intensifies, and societal expectations for corporate sustainability grow stronger. Several trends will shape the industry’s evolution and create opportunities for both consulting firms and their clients.
Mandatory assurance requirements expanding from the top five hundred to top one thousand listed companies by fiscal year 2026-27 will surge demand for ESG verification services, creating opportunities for firms developing robust assurance methodologies and training auditors in sustainability data verification. Value chain reporting, though currently voluntary, will eventually become mandatory as regulators recognize that comprehensive ESG disclosure must extend beyond direct operations to encompass entire value chains where most environmental and social impacts often occur.
Technology integration will accelerate as companies seek automated solutions for ESG data collection, multi-framework reporting, performance monitoring, and stakeholder communication. Consulting firms that develop proprietary digital platforms or forge strategic partnerships with technology providers will gain competitive advantages over those relying solely on traditional advisory approaches. Artificial intelligence and machine learning applications will enable more sophisticated ESG risk assessment, scenario modeling, and optimization of sustainability interventions.
Industry specialization will deepen as generic ESG consulting gives way to sector-specific expertise addressing unique sustainability challenges in industries including energy transition in power generation, sustainable aviation fuels for airlines, regenerative agriculture for food companies, and ethical supply chains for apparel manufacturers. Consulting firms developing deep industry capabilities will differentiate themselves from generalist competitors.
Integration of climate and nature represents an emerging frontier as biodiversity loss gains recognition alongside climate change as a critical planetary crisis. Consulting firms will help clients understand dependencies on ecosystem services, assess nature-related risks using frameworks like the Taskforce on Nature-related Financial Disclosures, and develop strategies protecting and restoring biodiversity throughout value chains.
