ESG in Companies: What It Is and Why It Matters

Have you ever stopped to think about what really lies behind a company when it claims to be “sustainable”? In recent decades, terms like “environmental responsibility” and “corporate citizen” have come to dominate corporate communications — but often without much substance. It was in this scenario that the concept of ESG (Environmental, Social and Governance) emerged, a framework that proposes to go beyond discourse and transform good practices into verifiable metrics.

Today, in 2026, ESG has ceased to be a trend to become a requirement. Investors, consumers, regulators, and even employees demand that companies demonstrate real commitment to the planet and to people. In Brazil and worldwide, organizations that ignore these criteria face increasingly concrete financial, reputational, and operational risks. And those that embrace ESG seriously find new growth opportunities, access to capital, and customer loyalty.

This article will explain what ESG is in a clear and practical way, why it matters for companies — and also for you, as a consumer and citizen. After all, understanding this universe is the first step to demanding more from the brands you support and making more conscious consumption choices.

What ESG Means: The Three Dimensions Explained

The ESG acronym brings together three distinct but deeply interconnected pillars. Understanding each one is essential to assess whether a company really practices what it preaches.

E for Environmental — The Environmental Pillar of ESG

The environmental component evaluates how a company impacts the environment and how it manages these impacts. This includes:

Greenhouse gas emissions and decarbonization targets
Energy consumption and efficiency, including use of renewable sources
Waste management and circular economy
Conscious water use and impacts on water resources
Deforestation, land use and impacts on biodiversity

A company with good environmental performance not only complies with legislation — it seeks to go further, reducing its ecological footprint and actively contributing to ecosystem recovery.

S for Social — The Social Pillar of ESG

The “S” evaluates how the company treats people: employees, suppliers, customers, and communities where it operates. The criteria include:

Working conditions, occupational health and safety
Diversity, equity and inclusion in employee and leadership composition
Respect for human rights throughout the supply chain
Social impact in local communities where the company operates
Privacy and security of customer data

G for Governance — The Governance Pillar of ESG

Governance concerns how the company is directed and controlled. Good corporate governance involves:

Transparency in financial statements and sustainability reports
Fighting corruption and bribery
Diverse board of directors composition
Executive compensation aligned with long-term performance
Protection of minority shareholder rights

How ESG Originated and Its History

The formal origin of the term ESG dates back to 2004, when then UN Secretary-General Kofi Annan invited leaders of major financial institutions to study how to integrate environmental, social, and governance factors into capital markets. The result was the report “Who Cares Wins”, which coined the ESG acronym and laid the groundwork for the movement.

Since then, evolution has been accelerated. The creation of the Principles for Responsible Investment (PRI), also in 2006 and under UN auspices, scaled the concept among asset managers. The Paris Agreement, signed in 2015, put climate at the center of the global corporate agenda. And IPCC reports published in subsequent years made it increasingly clear that climate risks are financial risks — something the market can no longer ignore.

In Brazil, the trajectory of ESG gained momentum with initiatives such as the creation of the Corporate Sustainability Index (ISE) of B3, which has existed since 2005 and brings together companies with good sustainability practices listed on the Brazilian stock exchange. More recently, CVM Resolution No. 59, published in 2021 by the Securities and Exchange Commission, began requiring publicly held companies to disclose information about risks and opportunities related to climate change — a significant regulatory milestone for the national market.

Why ESG Matters for Companies Today

The most common question from managers and entrepreneurs is still: “Is ESG just a cost or does it also generate returns?” The answer, supported by growing evidence, is that well-implemented ESG reduces risks and opens real opportunities.

Access to Capital and ESG Investors

The volume of assets under management with ESG criteria has grown significantly over the past decade worldwide. Large international funds and managers like BlackRock, Vanguard, and Itaú Asset Management in Brazil have begun incorporating ESG criteria into their analysis processes. This means that companies without good practices may have restricted access to cheaper credit and institutional investors of significant weight.

Reduction of Operational and Regulatory Risks

Companies exposed to climate, labor, or inadequate governance risks are more susceptible to fines, lawsuits, operational interruptions, and reputational damage. In Brazil, environmental legislation — including the Forest Code and the Environmental Crimes Law — already imposes severe responsibilities. As regulatory requirements intensify, companies with consolidated ESG systems are better prepared.

Attraction and Retention of Talent

Research conducted by global consulting firms consistently shows that professionals — especially younger generations — prefer to work in organizations with clear purpose and sustainable practices. In a competitive talent market, ESG culture can be a decisive differentiator.

Customer Loyalty

The Brazilian consumer is increasingly attentive to product origin and brand behavior. Companies with verifiable ESG commitments build more lasting relationships with their customers — and this is reflected in sales and brand loyalty.

ESG in Brazil: Advances, Challenges, and Local Context

Brazil occupies a unique position in the global ESG debate. On one hand, it holds a significant portion of the planet’s biodiversity, including the Amazon, the Cerrado, the Pantanal, and other biomes of strategic importance. On the other, it faces historical challenges of deforestation, social inequality, and informality in the supply chain.

In the agricultural, mining, and energy sectors, ESG pressure has been especially intense — both from external markets and from national regulators. Brazilian agribusiness, for example, faces growing scrutiny from European and North American buyers who demand proof of traceability and environmental compliance.

In the energy field, expansion of renewables is a positive point: Brazil has one of the cleanest electrical matrices in the world, with significant participation from hydroelectric, wind, and solar sources — managed in part by ANEEL (National Electric Energy Agency). This data favors national companies in global ESG evaluations.

However, Brazil still faces structural challenges. Labor informality, income concentration, and pressure on native biomes are real obstacles to solid ESG performance in many sectors of the economy.

How to Assess if a Company Really Practices ESG

With growing interest in the topic, the so-called greenwashing has also grown — when a company presents itself as sustainable without that corresponding to reality. Being able to identify genuine practices is essential for consumers, investors, and business partners.

Here’s what to watch for:

Published and audited sustainability reports by third parties, following recognized standards such as GRI (Global Reporting Initiative) or SASB
Climate targets with clear timelines and methodology, aligned with science (ex.: Science Based Targets — SBTi)
Independent certifications such as ISO 14001 (environmental management), SA8000 (social responsibility) or sustainable origin seals
Transparency about the supply chain, especially in high-risk sectors
History of actions, not just statements — compare what the company says with what the data shows

Beware of companies that use vague language like “we care about the environment” without presenting targets, data, or independent verification.

What You Can Do: ESG Starts With the Consumer Too

ESG is not just a conversation between companies and investors. As a consumer, you have real power to influence this movement. Your purchasing choices, the products you value, and the companies you decide to support or boycott send important signals to the market.

Here are practical attitudes you can adopt today:

Research before you buy: look for the company’s sustainability report or search for recognized certifications on products
Prioritize companies with transparent labor practices and that demonstrate respect for diversity
Avoid products with questionable traceability, especially in food, cosmetics, and fashion
Reduce superfluous consumption — the best sustainable product is the one you don’t need to buy
Value the circular economy: buying used, renting, or trading are ways to reduce demand for new production
Hold brands accountable: use social media and customer service channels to ask about ESG practices

To deepen this behavior in your daily life, the concept of conscious consumption offers a practical and accessible path to align your habits with your values.

Conclusion: ESG Is a Path, Not a Destination

ESG is not a magic solution, nor is it a certification that a company achieves and puts in a drawer. It is a continuous improvement process, which requires real commitment, transparency, and willingness to evolve. Companies that take this seriously not only contribute to a more just and sustainable world — they also position themselves better to thrive in a rapidly transforming business environment.

And you, as a consumer, professional, or investor, have an active role in this equation. By understanding what ESG is and demanding consistency from the companies that are part of your life, you contribute to raising the standard of the entire market.

The good news is that this transformation is already underway — and every conscious choice you make is part of it.
