What is ESG and why every Brazilian company should care about it now
Have you ever refused to buy from a brand because you found out it mistreats employees or pollutes the local river? Or did you choose a product with recyclable packaging without knowing exactly why, but feeling it was the right choice? This instinct has a name in the corporate world: ESG. And what seemed to be an issue only for large multinationals has now arrived at small and medium-sized Brazilian companies.
ESG is the English acronym for Environmental, Social and Governance, which in Portuguese means environmental, social and governance. These are three pillars that assess how much a company really cares about the planet, the people around it, and how it is managed. It’s not philanthropy. It’s not green marketing. It’s a profound change in the way business is conducted, and it affects suppliers, employees, consumers and investors all at once.
By the time you finish reading this article, you’ll understand what each pillar means in practice, how ESG is already changing the Brazilian market, and what your company can do now, even if it’s a small business.
The three pillars of ESG explained without complication
Environmental: what the company does with the planet
The “E” for Environmental covers everything the company consumes and discards: energy, water, carbon emissions, waste, land use. A bakery that installs solar panels to reduce its electricity bill, as explained in this guide on solar energy that reduces your electricity bill year-round, is already acting on the environmental pillar, even without knowing how to use the ESG acronym.
For a company, the practical questions are: where does the energy you use come from? How much waste do you generate and where does it go? Do you know Law 12.305/2010, the National Solid Waste Policy, which requires manufacturers and importers to properly dispose of their products? This is the type of regulation that already impacts companies of all sizes in Brazil.
Social: what the company does for people
The “S” for Social measures how the company treats those around it: employees, suppliers, local community and customers. This includes fair wages, diversity on the team, workplace safety and respect for human rights in the supply chain.
If a company buys fabric from a supplier that uses labor analogous to slavery, it fails on the social pillar even if the problem is “far away” from it. The Ministry of Labor and Employment maintains the so-called “dirty list” of employers caught in this situation, and being associated with it can destroy a brand’s reputation in hours on social media.
Governance: how the company is managed
The “G” for Governance is the most technical of the three, but also the most decisive for investors. It addresses transparency, ethics, anti-corruption, leadership structure and accountability.
A company with good governance publishes honest reports on its performance, has clear rules against conflicts of interest, and doesn’t depend on a single owner who makes all the decisions alone. This reduces risks for investors and customers. In Brazil, the Anti-Corruption Law (Law 12.846/2013) already holds companies accountable for corrupt acts by their employees, which makes governance a legal issue, not just an ethical one.
Why ESG is no longer optional in the Brazilian market
Brazil is the fifth largest country in the world and has one of the largest biodiversities on the planet, according to data from the Ministry of Environment. This places the country at the center of the global debate on sustainability, but also creates real pressure on companies operating here.
In recent years, major retail chains and industries have begun requiring their suppliers to present ESG criteria to remain on their roster. A small packaging factory in the interior of São Paulo, for example, could lose a contract with a national network if it can’t prove that it properly handles its waste. This chain of pressure reaches the microentrepreneur.
On the financial side, the credit market has also changed. Brazilian public and private banks have begun offering credit lines with lower interest rates for companies with good environmental and social practices. The so-called green credit or sustainable finance is already a reality that affects the cost of money for your business. Ignoring ESG could mean paying more to finance a new machine or expand inventory.
How to know if your company is already practicing ESG without knowing it
Many Brazilian companies already do things right without ever having heard of ESG. See if you identify with any of these situations:
- You separate garbage and properly dispose of packaging, paper and discarded electronics
- You pay your employees on time, ensure all labor rights and provide a safe environment
- You buy from local suppliers whenever possible, reducing transport and supporting the region’s economy
- You have some written policy on how the company should act in situations of conflict or complaints
- You know your business’s energy and water consumption and seek to reduce it
If you marked at least two items, you already have a real foundation to build on. ESG doesn’t need to start from scratch.
Practical steps to start implementing ESG in your company
Implementing ESG doesn’t require expensive consulting or a sustainability department. It starts with organization and honesty. Here’s a possible path:
- Do a simple diagnosis: List what your company consumes (energy, water, supplies), what it discards and how it treats the people involved. Without judgment. Just observation.
- Choose one pillar to start with: Don’t try to change everything at once. If waste is the most urgent problem, start with the environmental pillar. If the internal team climate is bad, start with the social one.
- Document everything: Note simple goals, like “reduce energy consumption by 10% by the end of 2026” or “hire at least two local suppliers by June”. What is not recorded does not exist.
- Involve your team: Sustainability is not the responsibility of the owner alone. When employees participate in decisions, changes last longer. Have a short meeting, explain what ESG is in your own words and ask what they suggest.
- Communicate with transparency: If you improved something, tell your customers, but without exaggerating. Greenwashing, which is the practice of pretending to be sustainable without real basis, has already caused lawsuits and fines in Brazil. The National Council of Advertising Self-Regulation (Conar) has already judged cases of misleading advertising in sustainability.
- Seek progressive certifications: There are Brazilian certifications like the Brazilian GHG Protocol Program for carbon emissions and the seal from the Akatu Institute for responsible companies. Start with free or low-cost ones.
- Review and adjust every six months: ESG is an ongoing process. What worked this year may need adjustment next year.
The most common mistakes when starting to talk about ESG
The first mistake is confusing ESG with donations to NGOs. Sponsoring a tree-planting event once a year doesn’t compensate for uncontrolled carbon emissions the rest of the time. The concept requires consistency, not one-off gestures.
The second mistake is treating ESG as a cost. Companies that reduced energy consumption, decreased production waste and improved working conditions frequently report declines in operating costs and increases in employee retention. Less turnover means less spending on hiring and training.
The third mistake, and perhaps the most dangerous, is communicating more than you practice. Saying you’re a “green company” without any concrete data to prove it is greenwashing. In 2026, Brazilian consumers have easy access to information and quickly distrust empty promises.
Frequently asked questions about ESG
Is ESG mandatory for small businesses in Brazil?
There is still no law that formally requires all companies to adopt ESG. But various regulations already touch on parts of the concept, such as the National Solid Waste Policy and the Anti-Corruption Law. The practical obligation comes from the market: customers, banks and large buyers already demand ESG criteria from their suppliers.
How does ESG affect my final customer, the individual person?
The Brazilian consumer is increasingly attentive to the origin of the products they buy. Research by the Akatu Institute shows that a growing portion of Brazilians declare they consider the company’s ethical stance before buying. This means ESG can be a real sales differentiator, not just a regulatory obligation.
Do I need to hire a consulting firm to start?
No. The initial diagnosis can be done internally, with simple spreadsheets and honest conversations with the team. Specialized consultancies make sense in more advanced phases, when the company already has defined goals and wants formal certification or wants to raise investment with ESG criteria.
What is a sustainability report and does my company need one?
A sustainability report is a document that describes a company’s environmental, social and governance practices. Companies with publicly traded capital on the Brazilian stock exchange (B3) already have disclosure obligations in this area. For smaller companies, the report is not mandatory, but it can be a powerful tool for attracting demanding customers and suppliers.
A concrete action to take today
If all this seemed too big, reduce it to the bare minimum: choose one small thing your company already does well and write it in one sentence. It could be “we use recyclable packaging” or “we pay all rights on time”. That’s the starting point. From there, the next question is always the same: what else can we improve?
ESG is not about being perfect. It’s about being honest about what you do and committing to improve. And that, any company, of any size, can start now.
