Sustainability Reporting












Why start with sustainability reporting now?
The pressure to report on sustainability is increasing from all sides. Customers are making more demands, and investors want to see transparency. Even companies that are not legally obliged benefit from voluntary reporting. Those who act now will be ahead in a changing market.
Voluntary reporting pays off
Even if you are not legally obliged, voluntary reporting gives you an edge over competitors and shows stakeholders that you are forward-thinking.
Customers ask for it
More and more customers demand solid sustainability data from their suppliers. Without reporting, you miss opportunities with large customers.
Financing advantage
ESG criteria are becoming increasingly important for financing. A well-substantiated sustainability report opens doors with investors and banks.
Competitive advantage
Companies with strong sustainability reporting more often win tenders and more easily attract employees.
Through which frameworks?
CSRD
Comply with EU legislation for large companies with an audit-proof report that convinces stakeholders.
VSME
Report tailored to your SME using the Voluntary SME framework, without unnecessary complexity.
SBTi
Set science-based climate targets and report on your progress towards net-zero.
GRI
Report according to the most widely used international standard for sustainability reporting.
5 steps to a sustainability report
Defining the context
Together, we outline your company's context and determine the most suitable reporting framework. Is reporting legally mandatory? Which entities need to be included? We assess what's already in place and choose the right framework for your needs and sector.
Materiality analysis
We determine which sustainability topics are a priority for your organization and stakeholders. For CSRD, we apply double materiality – the impact of your company on people/environment AND the impact of sustainability topics on your company value.
Gap analysis
We compare your current processes and available data against the chosen reporting requirements. This gives you a clear overview of what's already in place and what's still missing.
Strategic plan
We develop a roadmap with objectives (short/medium/long term), select measurable KPIs to track progress, and create a concrete action plan to achieve goals.
Reporting
We prepare the sustainability report according to the selected standards – whether it's CSRD, GRI, VSME, or a combination. The report can be combined with other frameworks like SBTi if desired.

Frequently asked questions

We work according to ESRS standards, which are mandatory under the new European CSRD regulations. These standards not only help you meet legal requirements but also ensure your reporting is globally recognized and understood. Depending on your company's needs, we can also integrate other reporting frameworks, such as the Global Reporting Initiative (GRI) and the Sustainable Development Goals (SDGs).
Double materiality considers both the impact your company has on people and the environment (impact materiality) and how external sustainability issues affect your company's financial performance (financial materiality). For example, if your company relies on scarce raw materials, this not only impacts the environment but also your company's value. This broad perspective ensures that your sustainability strategy creates value both internally and externally.
Setting up a sustainability reporting system can be complex, especially in large organizations with diverse activities. Typical challenges include collecting consistent data across different locations, choosing the right reporting framework, and integrating sustainability into existing business processes. We help you overcome these challenges with a streamlined, scalable approach that aligns with your business goals.
In your sustainability report, focus on the financial impact of your sustainability initiatives. Show how sustainable initiatives and actions contribute to cost savings, risk management, and long-term value creation. Use clear KPIs and benchmarks to measure your progress and communicate how sustainability strengthens your business strategy.
