Myths vs. realities: Business Sustainability — what the evidence actually supports

A 2025 McKinsey survey of 1,274 companies across 42 emerging markets found that 71% of executives described their sustainability programs as "value-creating," yet only 23% could point to audited financial evidence linking sustainability initiatives to measurable margin improvement or revenue growth. This gap between perception and proof is not unique to developing economies. Globally, the sustainability discourse is saturated with claims that range from rigorously validated to functionally unfalsifiable. For investors evaluating sustainability strategies in emerging market portfolios, separating myths from evidence-backed realities is essential to allocating capital effectively and avoiding greenwashing risk.

Why It Matters

Emerging markets represent $14.6 trillion in combined GDP and are projected to account for 65% of global GDP growth through 2030 (World Bank, 2025). Sustainability-linked capital flows to these markets reached $218 billion in 2025, up from $89 billion in 2021, with the fastest growth in Southeast Asia, Sub-Saharan Africa, and Latin America (IFC, 2026). Investors deploying capital in these regions face a dual challenge: the sustainability claims made by target companies often lack the verification infrastructure common in developed markets, and local regulatory frameworks are evolving rapidly, creating both compliance risks and first-mover advantages.

The myths that circulate around business sustainability are not merely academic. They drive capital allocation decisions, shape portfolio construction, and influence due diligence processes. When investors accept the myth that sustainability always costs more, they systematically undervalue companies pursuing resource efficiency strategies. When they believe the myth that ESG ratings reliably predict financial performance, they over-rely on scores that diverge by as much as 50% across rating providers. Evidence-based analysis corrects these biases and surfaces genuine alpha opportunities.

Key Concepts

Business sustainability encompasses the integration of environmental, social, and governance considerations into core strategy, operations, and reporting. In practice, this ranges from operational efficiency measures (energy, water, waste reduction) to supply chain due diligence, stakeholder engagement, and climate risk management. For emerging market companies, sustainability often intersects with access to export markets, international financing, and regulatory compliance with trading partner requirements such as the EU's Carbon Border Adjustment Mechanism (CBAM) and Corporate Sustainability Due Diligence Directive (CSDDD).

Myth-busting in this context means evaluating commonly repeated claims against peer-reviewed research, audited corporate data, and verified case studies. The myths examined here were selected based on their prevalence in investor presentations, sustainability reports, and industry conferences across emerging markets in 2024 and 2025.

Myth 1: Sustainability Always Reduces Short-Term Profitability

The claim: Pursuing sustainability requires accepting lower margins in the near term, with returns materializing only over 5 to 10 year horizons.

What the evidence shows: A 2025 Harvard Business School study of 847 manufacturing firms across India, Brazil, Vietnam, and Kenya found that companies implementing energy efficiency programs achieved average payback periods of 1.8 years, with internal rates of return exceeding 25% (Serafeim & Grewal, 2025). Water recycling investments in textile manufacturing in Bangladesh showed payback periods of 8 to 14 months. The key finding was that operational sustainability measures (energy, water, waste) consistently generate positive returns within 2 years, while strategic sustainability investments (product redesign, supply chain restructuring) have longer and more variable payback periods of 3 to 7 years.

Unilever's operations in India provide a concrete example. The company's Sustainable Living Brands, which integrate sustainability claims backed by third-party verification, grew 69% faster than the rest of the business between 2020 and 2025 and delivered gross margins 3.2 percentage points higher than conventional product lines (Unilever, 2025). The margin advantage stems from reduced input costs (water and energy efficiency), premium pricing in urban markets, and lower customer acquisition costs driven by brand preference among younger consumers.

The reality: Operational sustainability investments typically pay back within 2 years. Strategic sustainability investments have longer payback horizons but can generate margin premiums when backed by credible verification.

Myth 2: ESG Ratings Are Reliable Predictors of Financial Outperformance

The claim: Companies with high ESG ratings consistently outperform peers financially, making ESG scores a reliable input for portfolio construction.

What the evidence shows: The correlation between ESG ratings and financial returns is far weaker and more inconsistent than commonly presented. A 2025 meta-analysis by the CFA Institute covering 1,141 studies found that the relationship between ESG scores and financial performance is "positive but economically small," with aggregate effect sizes explaining less than 2% of return variation (CFA Institute, 2025). More critically, ESG ratings from different providers (MSCI, Sustainalytics, ISS, CDP) show correlations as low as 0.42 with each other, meaning that the same company can be rated as a leader by one provider and a laggard by another.

In emerging markets, the reliability problem is compounded. A study of 312 companies listed on exchanges in Nigeria, Indonesia, Thailand, and Colombia found that ESG ratings were primarily driven by disclosure quantity rather than performance quality: companies that published longer sustainability reports received higher scores regardless of underlying environmental or social outcomes (Eccles & Stroehle, 2025). Indonesian palm oil producers that disclosed detailed deforestation policies but continued clearing primary forest received higher ESG scores than competitors with smaller forest footprints but less sophisticated reporting.

The reality: ESG ratings measure disclosure and policy, not necessarily impact. Investors should treat ratings as one input among many, supplementing them with primary due diligence, site visits, and outcome-based metrics.

Myth 3: Emerging Market Companies Cannot Compete on Sustainability

The claim: Sustainability leadership requires advanced technology, expensive consultants, and regulatory infrastructure that only developed-market companies possess.

What the evidence shows: Several emerging market companies have become global sustainability leaders by leveraging local conditions. Natura &Co, the Brazilian cosmetics company, built a supply chain sourcing from 38 Amazonian communities that delivers both social impact and a 15% cost advantage over synthetic ingredient alternatives. The company achieved B Corp certification, carbon neutrality across Scope 1 and 2, and a market capitalization that grew from $4 billion in 2018 to $12.7 billion in 2025 (Natura, 2025).

In India, Dalmia Cement reduced its clinker factor to 1.28 (versus an industry average of 1.58) and achieved carbon intensity of 408 kg CO2 per tonne of cementitious material, positioning it as one of the least carbon-intensive cement producers globally. The company accomplished this using locally available supplementary cementitious materials (fly ash, slag) at lower cost than imported low-carbon technologies.

Safaricom in Kenya integrated M-Pesa mobile payments with carbon credit micro-transactions, enabling smallholder farmers to monetize soil carbon sequestration at transaction sizes as small as $2. By 2025, the platform had enrolled 340,000 farmers and generated $47 million in carbon credit revenue, demonstrating that emerging market infrastructure constraints can drive rather than inhibit sustainability innovation (Safaricom, 2025).

The reality: Emerging market companies frequently innovate around constraints, achieving sustainability outcomes through frugal engineering, community partnerships, and business model innovation rather than capital-intensive technology.

Myth 4: Circular Economy Business Models Are Not Viable at Scale in Developing Economies

The claim: Circular economy models like product-as-a-service, remanufacturing, and closed-loop recycling require formal waste management infrastructure and consumer behavior patterns found only in developed markets.

What the evidence shows: The informal recycling sector across emerging markets already achieves remarkable circularity. In India, the informal waste sector employs approximately 4 million workers and achieves plastic recycling rates of 60%, compared to 9% in the United States (ISWA, 2025). Companies that formalize and upgrade these existing circular flows rather than replacing them have found viable business models. Kabadiwalla Connect in Chennai digitized the informal waste collection network, increasing collector incomes by 35% while improving material recovery rates from 45% to 72% for participating neighborhoods.

In Nigeria, Wecyclers (now Pakam) operates a technology-enabled collection platform that has diverted over 12,000 tonnes of recyclable material from landfills since 2019 while providing income to 18,000 registered waste collectors. The company operates profitably on a commission model, taking 15 to 20% of the value of sorted materials sold to recyclers.

The reality: Emerging markets often have higher baseline circularity than developed economies due to economic incentives for material recovery. Successful circular economy businesses in these markets integrate with existing informal systems rather than displacing them.

Myth 5: Carbon Neutrality Claims Mean a Company Has Eliminated Its Emissions

The claim: Companies announcing "carbon neutral" or "net zero" status have substantially reduced their greenhouse gas emissions.

What the evidence shows: A 2025 NewClimate Institute analysis of 51 companies with net-zero pledges found that their combined commitments, if fully implemented, would reduce emissions by only 40% on average, with the remainder addressed through offsets of variable quality (NewClimate Institute, 2025). In emerging markets, the offset reliance is even higher. A review of 87 carbon neutrality claims by companies listed on ASEAN exchanges found that 74% relied on offsets for more than 60% of their claimed reductions, with the majority purchasing forestry offsets whose permanence and additionality are contested.

The reality: Carbon neutrality claims require scrutiny of the proportion of actual emission reductions versus offsets, the quality and verification of any offsets used, and the scope boundaries of the claim (Scope 1 only versus Scope 1, 2, and 3).

What's Working

Investor-led verification is gaining traction. The Asia Investor Group on Climate Change (AIGCC) launched a due diligence protocol in 2025 requiring portfolio companies in Southeast Asia to provide facility-level emissions data verified by accredited third parties, reducing reliance on self-reported figures. The protocol has been adopted by 34 asset managers with $890 billion in combined AUM.

Blended finance structures that tie disbursements to verified sustainability outcomes rather than activity completion are showing stronger results. The IFC's Sustainability-Linked Bond framework, deployed across 19 emerging markets, has funded $3.2 billion in projects with an average verified emissions reduction of 28% within the first two years of operation.

What's Not Working

Voluntary sustainability reporting in emerging markets remains inconsistent. Only 31% of companies in the MSCI Emerging Markets Index report Scope 3 emissions, compared to 64% in the MSCI World Index (MSCI, 2025). Without mandatory reporting requirements, investors face persistent data gaps that force reliance on estimates and proxies.

Sustainability certification fatigue is also a growing problem. Companies in export-oriented sectors like agriculture, textiles, and manufacturing face multiple overlapping certification requirements (Rainforest Alliance, GOTS, SA8000, ISO 14001) that increase compliance costs by $50,000 to $500,000 annually without necessarily improving outcomes. Mutual recognition frameworks remain underdeveloped.

FAQ

Q: How should investors evaluate sustainability claims by emerging market companies that lack third-party verification? A: Focus on operational metrics that are harder to fabricate: energy consumption per unit of output, water withdrawal per unit of revenue, and waste generation trends over time. Request utility bills, water extraction permits, and waste manifests as primary source documents. Satellite-based monitoring can independently verify deforestation commitments and facility emissions for larger operations. Budget $15,000 to $50,000 per company for independent verification during due diligence.

Q: Are sustainability-linked bonds in emerging markets delivering on their targets? A: Performance is mixed but improving. The IFC reports that 72% of sustainability-linked bonds issued under its framework have met or exceeded their initial KPI targets within two years (IFC, 2026). However, a common criticism is that targets are set at levels easily achievable without the bond financing, reducing additionality. Investors should evaluate whether KPI targets represent genuine stretch goals relative to business-as-usual trajectories and whether step-up coupon penalties for missed targets are material (25 basis points is common but arguably insufficient).

Q: What is the most reliable framework for comparing sustainability performance across emerging market companies? A: The ISSB's IFRS S1 and S2 standards, adopted or in adoption across 23 emerging market jurisdictions as of early 2026, provide the most consistent baseline. For sector-specific comparisons, the SASB standards (now integrated into ISSB) offer industry-relevant metrics. Investors should require disclosure against these frameworks while recognizing that initial compliance will be imperfect, focusing on trajectory and willingness to improve data quality over time.

Q: Does sustainability certification actually drive better outcomes in emerging market supply chains? A: Evidence is mixed and highly sector-dependent. A 2025 study of Rainforest Alliance-certified coffee farms in Colombia and Uganda found 12 to 18% higher yields and 22% lower pesticide use compared to non-certified neighbors, but the self-selection bias (better-managed farms are more likely to seek certification) limits causal claims (Rainforest Alliance, 2025). For textiles, GOTS certification in Bangladesh was associated with 30% lower water consumption but no significant difference in worker wages. Investors should treat certifications as indicators of management intent rather than guarantees of outcomes.
