ESG assessment: definition, relevance and strategies for your company's success

The importance of ESG assessments has increased rapidly in recent years. Investors, banks, business partners and regulatory authorities are placing ever greater emphasis on sustainability assessments. But what is behind the term ESG rating? What new standards will apply in the EU in the area of ESG rating regulation in the future? And how can companies improve their ESG performance in order to achieve a top rating? We have compiled the answers in a compact format.

ESG rating definition: The three pillars of sustainability assessment

An ESG assessment evaluates sustainability and responsible corporate governance on the basis of three key criteria: Environment (Environmental), Social (Social) and Governance (Governance). The aim of this assessment is to make a company's non-financial risks and opportunities transparent and comparable.

The three pillars of ESG valuation:

Environment: This area covers the environmental impact of a company. This includes CO₂ emissions, energy efficiency, resource conservation, waste management, biodiversity protection and pollution prevention.

Social: Relationships with stakeholders are assessed here. This includes working conditions, fair wages, diversity, respect for human rights in the value chain, employee engagement, relationships with local communities and product safety.

Governance (corporate management): This aspect focuses on internal management and ethical principles. It includes compliance, transparency of structures and processes, quality of company management, shareholder rights, corruption prevention and ethical management.

How ESG valuations are scaled:

ESG assessments are carried out by providers external to the company. They show how well a company integrates sustainable and ethical practices into its own business activities. The result is usually presented as a grade or score. Common scales are ratings from AAA (very good) to CCC (unsatisfactory) or a point scale from 0 to 100. The methodology and weighting of the criteria vary depending on the rating agency.

Which companies are affected?

ESG ratings are generally voluntary, but are increasingly becoming standard in many sectors and capital markets. They relate in particular to:

• Listed companies, as investors actively incorporate ESG assessments into their investment decisions.
  
  
• Companies with international supply chains that have to meet the ESG requirements of business partners.
  
  
• Borrowing companies, as banks are increasingly taking ESG scores into account when granting and pricing financing.
  
  
• Large companies in the regulatory focus, for example through the EU taxonomy, the SFDR or the CSRD, which require high-quality ESG data.
  
  
• Small and medium-sized enterprises and SMEs, as ESG ratings are now mandatory in many tenders - especially in the public sector - and play a role in deciding who is awarded the contract. They create trust among business partners and secure the company's position in important supply chains. Without an ESG rating, companies often miss out on long-term business opportunities and stable partnerships.

There is currently no legal obligation to carry out an ESG assessment. Nevertheless, pressure from financial market players, customers or stakeholders can make an ESG assessment de facto necessary - especially for companies that are seeking capital or are part of complex value chains.

Why are ESG ratings so important for companies?

ESG assessments play a decisive role in many areas of business today:

Meeting customer expectations and requirements in the supply chain

Not only end consumers, but also business customers demand proof of solid ESG performance from their partners and suppliers. A positive rating creates competitive advantages when awarding contracts.

Risk management and minimization of regulatory risks

A strong ESG rating indicates robust internal processes and proactive risk management. This helps to reduce operational, regulatory and reputational risks.

Access to capital and financing

Access to capital and financing

Investors and banks are attaching increasing importance to sustainability performance. A good ESG rating indicates lower risks and attractive long-term returns. This facilitates access to capital and leads to more favorable financing conditions.

Attractiveness as an employer

Companies that operate sustainably attract talented specialists. Employees pay more attention to the values and social responsibility of their employer. A good ESG rating therefore strengthens employer branding.

Increase in company value and competitiveness

In the long term, ESG ratings influence the value of a company and its competitive position. Companies with good ESG performance are more resilient to crises and better equipped for a sustainable future. To achieve this, sustainability should not be a stand-alone strategy paper, but an integral part of your overall corporate strategy.

How is an ESG assessment prepared? Insights into the process

Specialized agencies such as MSCI, Sustainalytics and EcoVadis are responsible for preparing an ESG assessment. The typical assessment process comprises four main steps:

1. Data collection: Companies provide ESG-relevant information, e.g. via detailed questionnaires, sustainability reports or special platforms such as Planted.
2. Data analysis: The ESG data collected is analyzed and evaluated using industry-specific benchmarks and defined criteria.
3. Scoring and weighting: Individual ESG topics are weighted differently based on their relevance to the respective sector. These individual ratings are incorporated into an overall rating.
4. Report and result: The evaluated company receives a detailed report with results, strengths, weaknesses and concrete potential for improvement.

Important: Some agencies also create ratings based on publicly available information ("unsolicited rating") if companies do not actively provide data. However, these can be less precise. Proactive cooperation with the rating agencies is therefore recommended.

Current challenges in ESG ratings: lack of transparency and comparability

The ESG rating landscape is currently still characterized by a number of challenges:

• Different methods: Each rating agency uses its own valuation approaches, criteria and weightings. This makes comparability more difficult.
• Lack of transparency: Many of the detailed valuation models remain opaque and not fully transparent for companies.
• Comparability: The different approaches make it difficult to directly compare ESG ratings from different providers.
• Costs: Obtaining certified ESG assessments can require significant investment.

It is precisely for these reasons that the European Union is working intensively on a new regulation of the ESG rating market.

The new EU ESG Rating Regulation: More transparency and quality

In order to ensure greater transparency, quality and comparability in ESG ratings, the European Commission published a new regulation on the transparency and integrity of ESG ratings in the EU Official Journal on December 12, 2024. However, the regulation will not apply until July 2, 2026.

The aim of the regulation is to create uniform requirements for ESG rating providers in the EU, to ensure consumer and investor protection and to reduce greenwashing and misinformation.

The central contents of the proposal:

• Licensing requirement: ESG rating providers based or operating in the EU must be registered and meet regulatory requirements.
  
  
• Transparency requirements: Assessment methodology, weighting of E, S and G factors and data sources must be disclosed.
  
  
• Avoidance of conflicts of interest: Providers may not, for example, provide advice and ratings for the same client at the same time.
  
  
• Accountability: Users of ESG ratings - such as investors or companies - should be able to rely on comprehensible and objective information.

Effects on companies

Even though the regulation addresses ESG rating providers, it has an indirect impact on companies: In order for ESG ratings to be recognized and comprehensible in the future, companies must provide their ESG data in a more consistent, structured and verifiable manner. Those who invest in professional ESG data management at an early stage will gain clear advantages.

How companies improve their ESG rating: practical strategies

Good ESG performance does not happen by itself. You can use the following five measures to optimize your ESG rating in a targeted manner:

1. Develop a structured ESG strategy: Define clear, measurable targets (KPIs) and responsibilities within your company. This will strategically align your sustainability efforts.
2. Improve ESG data quality: Rely on a comprehensive, comprehensible and digitally recorded data basis for your ESG reporting. Verified data creates trust and increases the accuracy of your rating.
3. Establish regular ESG reporting: Publish transparent and audited sustainability reports. These document your progress and strengthen the trust of your stakeholders.
4. Proactive communication with rating agencies: Maintain an open dialog with rating agencies. Respond to inquiries in full, provide relevant context and highlight special initiatives.
5. Early preparation for new standards: Keep yourself continuously informed about new ESG standards and regulations such as the CSRD. Adapt your processes in good time. The use of specialized ESG software such as Planted can considerably simplify your ESG data management and CSRD-compliant reporting.

Tip: Companies that systematically record and manage their sustainability information not only improve their ESG rating. They also optimize their operational efficiency and secure long-term competitive advantages.

Conclusion: ESG assessment as a strategic success factor for sustainable corporate success

A strong ESG rating is increasingly becoming a key success factor for companies. It not only influences relationships with investors and banks, but also the competition for the best talent, demanding customers and strategic partners. The ability to transparently present and continuously improve one's own ESG performance is crucial to the future success of a company.
