ESG in the practice of companies

Consumers and investors alike have become increasingly aware of sustainability and social responsibility in recent years. In response to growing societal expectations and changing EU regulations, ESG (Environmental, Social, Governance) reporting requirements are being extended to more and more companies and sectors.

For companies, this means not only complying with new regulations such as the CSRD Directive or the SFDR Regulation, but also implementing appropriate analytical tools, data collection systems and advisory services to enable reliable reporting and management of ESG indicators.

Importantly, there is also growing evidence that a commitment to sustainability can deliver real financial benefits. For example, companies that regularly report their carbon emissions achieve an average 67% higher return on investment than those that do not.

Such results can be attributed to increased investor confidence, improved energy efficiency, better risk management and the ability to attract informed consumers and talent. ESG is therefore no longer just a regulatory requirement – it is becoming a strategic tool for building competitive advantage.

Why are ESG tools crucial now?


ESG tools are not just a technical solution to support reporting – they are becoming the foundation of modern risk management, growth strategy and building sustainable competitive advantage.

Research shows that companies that invest in ESG tools perform better in the market and better respond to investor and consumer expectations. By introducing ESG tools and a carbon footprint reporting calculator, businesses can not only simplify preparation, but also reduce the risk of errors that may arise in the face of the desire to meet new regulations.

  • 53% of Polish company representatives expect an improvement in financial performance after implementing ESG reporting principles and tools.
  • 69% of companies have already implemented or are in the process of implementing non-financial reporting tools, such as carbon footprint calculators or ESG data analysis platforms.
  • 39% of managers point to improving the company’s image as the main motivation for investing in ESG, and 37% see an increase in customer engagement.
  • More than 50% of Polish companies believe that ESG reporting will encourage investors.
  • 75% of investors pay attention to ESG issues when making investment decisions.
  • More than 80% of investors would pay at least 3% more for an acquired company with a strong ESG policy.

  • meeting new sustainability requirements,
  • ensuring compliance with the CSRD (Corporate Sustainability Reporting Directive),

ESG and taxation and corporate responsibility

The integration of tax issues into ESG (Environmental, Social, Governance) strategies is becoming increasingly important for companies pursuing sustainability and responsible governance. A transparent approach to tax, including but not limited to the publication of a tax strategy, reporting of total tax contribution and compliance with international standards such as the Global Reporting Initiative or Total Tax Contribution, builds trust among investors, customers and regulators.

In addition, responsible tax management can bring financial benefits through the use of available tax credits and incentives related to investments in renewable energy, energy efficiency or eco-innovation. Integrating tax strategy with ESG objectives not only minimises tax risks, but also supports the long-term value of the company and its positive impact on society and the environment.

Transparent ESG data is becoming a key element of communication with stakeholders and investors.
