Holistic consulting for a sustainable future with the experts of Nexia GmbH

We want to support companies in mastering environmental and social challenges and thus contribute to the sustainable development of your company. We work with you on eye-level, individually and supportively. You are the experts for your business - we are the consultants for the blind spots that are often overlooked.

Sustainability strategy

The sustainability strategy should be firmly anchored in the corporate strategy while the responsibility for its implementation lies with the senior management. Employees are an important component in implementing the various measures to achieve sustainability goals. 

We support you with all ESG efforts

We conduct an in-depth assessment to identify existing gaps (GAPs), providing you with specific recommendations and proven best practices to help you close them. We systematically compare all regulatory requirements and prioritise the necessary measures, providing a structured basis for achieving your climate targets.

Climate targets should be an integral part of a corporate strategy. Successful climate targets are scientifically sound and structured, and geared towards implementation. They are also ideally tailored to your company and its challenges.

We support you in defining and integrating your climate targets efficiently into your corporate strategy.

Effective sustainability management requires clear structures. We help you set up governance that defines responsibilities, decision-making channels and processes, tailored to your company's size and structure.

Our focus areas:

  • Setting up governance structures (e.g. sustainability committees and responsibilities)
  • Integration into existing management systems
  • Allocation of roles and tasks

Internal communication and embedding in the corporate culture.

In the context of reporting, clear and documented sustainability policies are becoming increasingly important. They provide a foundation for consistent reporting and effective sustainability management.

We help you in developing and revising central company guidelines in accordance with the ESRS (European Sustainability Reporting Standards) and GRI (Global Reporting Initiative) requirements.

Develop a practical, targeted and customised sustainability strategy for your company. Our workshops provide in-depth knowledge and concrete action steps. We also regularly offer free webinars to provide an initial insight.

Climate management

As part of the 2015 Paris Climate Agreement, 196 countries committed to limiting global warming to 1.5 degrees Celsius or a maximum of 2 degrees Celsius. In response, Europe has developed the Green Deal. A key part of this plan is the Corporate Sustainability Reporting Directive (CSRD), which was introduced in 2021 and requires companies to provide information on their environmental, social and governance (ESG) practices.

Your path to carbon neutrality:

Goals should be SMART. This means they must be specific, measurable, achievable, relevant and time-bound. Companies can use the 17 Sustainable Development Goals set out by the United Nations or the Science Based Target Initiative's Net Zero goals as a guide.

It is important that the targets fulfil scientific and legal requirements. Only then will they be credible.

We are here to help you establish your personal climate goals, share them across your organisation and provide guidance on incorporating them into your overall business plan.

CO₂ emissions and a company's decarbonisation strategy are essential components of sustainability reports, whether prepared in accordance with the CSRD, VSME, GRI or DNK standards. The carbon footprint is important information for customers within the company's supply chain, providing insight into its sustainability. It is also relevant to banks and insurance companies, who assess the sustainability of a company based on its climate strategy and carbon footprint.

Recording CO₂ emissions reveals the areas of the company where targeted measures need to be taken to reduce emissions. In order to make the change measurable and controllable, a concrete implementation plan is crucial. The costs and timeframe are closely linked to investments and the company's profitability.

This process creates opportunities to optimise or even realign business models. However, the larger and more long-term the change, the less motivation there is to implement it. However, in view of climate change in particular, the necessary transformation towards climate neutrality must not be overlooked.

Those who actively embrace change will be ready for the future. We will support you on this journey with our in-depth expertise, pragmatic solutions, and timely encouragement.

Identifying and minimising financial, operational, legal and technical risks is key to a company's success. According to the Global Risk Report, the greatest risks in 2025 are armed conflicts between states (23%), extreme weather events (14%) and geo-economic conflicts such as trade tariffs (8%).

The specific risks a company faces depend heavily on its products or services. Some sectors are more affected by climate change than others. We can support your company in identifying, analysing and evaluating potential climate risks.

Efficient data management is essential for making informed decisions, optimising processes, and ensuring compliance with legal requirements, such as the GDPR. It is the foundation of sustainable economic success and digital competitiveness.

We would be delighted to advise you on the most suitable software programmes for your company from our partners.

From CO₂ reporting to decarbonisation strategies, our training courses show you how to implement effective and compliant climate management. Next to training and workshop formats, we offer free webinars to help you get started.

CSRD reporting

Various standards define how to prepare a legally compliant CSR report. This could be the European ESRS or the voluntary VSME. Additional sets of rules that can be helpful in preparing the report include the GRI or ISO 14064.

We can help you meet your specific reporting requirements

Prepare for the CSRD obligations in good time with our clearly structured roadmap. We will show you which steps are important now and how you can utilise time advantages by starting to collect data and select software early on.

Double materiality lies at the heart of the CSRD: which sustainability issues are financially relevant, and what impact does your company have on the environment and society? We can support you with analysis, prioritisation and documentation.

Whether it's GRI, ESRS, SASB or ISO - we help you choose the right reporting framework for your company. Together, we will develop a reporting structure that meets regulatory requirements and makes your sustainability performance visible.

Before you publish your sustainability report, we will check that it is complete, comprehensible and in line with the CSRD and ESRS. Our audit review provides independent, competent and practical feedback on the quality of your reporting, giving you certainty.

We help you efficiently record and structure sustainability-relevant data for CSRD reporting, providing customised advice on the right software solution.

Prepare for the CSRD and ESRS in a structured way. Our resources support you with double materiality, data collection and report preparation. We offer free introductory webinars and in-depth workshops to help you take the next step.

Sustainable supply chains

Every company has a due diligence obligation not to have a negative impact on society or the environment. This applies both to its own operations and along its supply chain. Supply chains have expanded as a result of globalisation, and it is becoming more difficult to keep an eye on them. Human rights and environmental protection are protected by both international and national laws. Lack of knowledge creates uncertainty and risks for companies.

We help to shed light on the tangled web of the supply chain

We analyse your purchasing and supply chain processes for sustainability risks and work with you to develop relevant KPIs to make social and environmental impacts measurable and controllable. This allows you to create transparency and certainty of action along the entire value chain.

We support you in implementing legal requirements such as the German Supply Chain Due Diligence Act (LkSG) and the upcoming EU CSDDD directive. Together, we identify risks, develop preventative measures and help you with the structured documentation of your due diligence obligations.

Rating

A sustainability rating assesses how well a company is positioned in terms of environmental, social and economic sustainability. Criteria such as environmental friendliness, social responsibility, fair working conditions and long-term financial stability are included in such an assessment. Stakeholders like customers, suppliers and investors base their decisions on the analyses of various rating agencies. 

We find the right rating for you

We analyse your current sustainability performance in relation to the relevant rating criteria. Based on this analysis, we will propose targeted optimisation measures to measurably improve your rating with the most common ESG rating agencies.

We create transparency in the jungle of ratings, whether it's EcoVadis, CDP, ISS ESG or others. We show you which rating systems suit your industry, target group and strategy. This allows you to make informed decisions about your positioning.

A good rating requires reliable, well-structured data. We can help you set up efficient processes for collecting and validating ESG-relevant information and preparing it for the rating.
