Unlocking Europe’s Green Rulebook
The European Union (EU) is taking major steps to make sure businesses and investors protect the planet, people, and future generations. Instead of leaving companies free to decide what “green” or “sustainable” means, the EU has built a clear system with rules everyone must follow.
At the heart of this system are three powerful tools:
- The EU Taxonomy—the rulebook that defines what counts as truly sustainable.
- The SFDR—rules for financial firms to explain how green their investments are.
- The CSRD—the reporting law that forces companies to disclose their sustainability performance.
Together, these three form a chain of trust. They help stop greenwashing, increase transparency, and give the public clear information about business activities. Let’s break them down in simple words.
The EU Taxonomy—Europe’s Green Dictionary
Think of the EU Taxonomy as a giant green dictionary or rulebook. It tells us exactly what counts as an environmentally sustainable activity. Without such rules, companies could claim almost anything is “green,” even if it isn’t.
To qualify as sustainable under the EU Taxonomy, a business activity must make a real, positive impact on at least one of six big environmental goals.
These six goals are
- Climate change mitigation—reducing harmful emissions.
- Climate change adaptation—preparing for rising seas, extreme heat, or wildfires.
- Water and marine protection—keeping oceans, rivers, and lakes healthy.
- Circular economy—reusing resources and cutting waste.
- Pollution control—reducing toxins and harmful chemicals.
- Protecting biodiversity—saving forests, animals, and nature.
If a company’s work supports these goals and avoids harming the others, it can be officially recognized as green.
But the taxonomy does not stop at definitions. It also requires companies to share data on:
- How much of their turnover (money made),
- How much of their CapEx (investment spending), and
- How much of their OpEx (daily operations)
Go into activities that qualify as green.
This makes it easier for the public, investors, and regulators to see which businesses are truly sustainable and which are not.
SFDR—Telling the Truth About Investments
Once we know what “green” really means, the next step is to check how money managers use this definition. That is where the Sustainable Finance Disclosure Regulation (SFDR) comes in.
Banks, insurance funds, and investment firms handle billions of euros every day. Some of them promise to invest in a greener future, but without rules, those promises could be vague or misleading. The SFDR solves this problem by forcing financial companies to disclose the truth about their products.
Under SFDR, funds and financial products are sorted into three clear categories:
- Article 6 funds—these do not claim to be green at all. They are regular investments.
- Article 8 funds—these are “light green.” They promote some environmental or social benefits, but it’s not their main goal.
- Article 9 funds—these are “dark green.” Their main purpose is to make a positive environmental or social impact.
This system makes it easier for anyone to know what they are really buying. If an investor chooses an Article 9 fund, they can expect their money to be used for sustainability goals, not just profit.
By making these categories public, the SFDR builds trust and accountability. It reduces the risk of greenwashing in the finance world and ensures investors get clear, reliable information.
CSRD – Holding Companies Accountable
Now we know how the EU defines sustainable activities and how financial firms must disclose investment practices. But one piece is still missing: company-level reporting. This is where the Corporate Sustainability Reporting Directive (CSRD) plays its role.
The CSRD requires large companies to report on their environmental, social, and governance (ESG) performance in detail. These reports must include information on how much of their activity is aligned with the EU Taxonomy.
Which companies must follow CSRD?
- Those with over 250 employees,
- Or €40 million in revenue,
- Or €20 million in assets,
- Plus all listed companies, regardless of size.
- Even non-EU companies must report if they have significant business in the EU.
This means thousands of companies are covered. Importantly, they cannot just use any reporting style they prefer. The CSRD requires them to follow the European Sustainability Reporting Standards (ESRS).

These standards create a common language for sustainability reporting. They make it possible to compare data across companies, industries, and countries. For example, investors can easily compare how two rival companies perform on carbon emissions, waste reduction, or biodiversity protection.
The three rules—EU Taxonomy, SFDR, and CSRD—work like pieces of a puzzle. The taxonomy defines what is green. The CSRD forces companies to report using that definition. And the SFDR makes financial firms explain how they use this company data in their funds.
Together, they build a transparent system where businesses, investors, and the public can clearly see who is truly sustainable and who is not. This reduces greenwashing, increases trust, and strengthens Europe’s role in building a fairer and greener economy.
