Making sustainability actionable and financially tangible.

Sustainability deserves one coherent solution. I help companies

  • identify regulatory requirements
  • make risks and opportunities financially tangible
  • build long-term processes and data.

My approach

A holistic picture of sustainability management

Sustainability is complex enough: its implementation should be efficient for every stakeholder involved. A lean data basis with clear responsibilities enables strategy, risk management and compliance at the same time, without extra effort or duplicated work.

The results

Reduce complexity, gain efficiency: analyse your climate and biodiversity risks along the regulatory requirements. Build strategies on top of them and measure success with unified KPIs.

The foundation

The management of sustainability activities should build on a unified basis of data, processes and real economic value.

Each area leads directly to the matching offer on the focus topics page.

Who I work for

I support companies where sustainability has to flow naturally into every process in the long run.

SmallMid-sizedGrowingcompanies with their own product

Regulatory requirements, customer requests and financial risks are reaching the products and supply chains of small and mid-sized companies ever more directly. Sustainability has long been more than reporting: emission prices hit procurement, production sites are destroyed, EU product requirements shape how products are designed.

Operational sustainability leads

You have no capacity left, yet requirements keep growing and getting more complex?

What I offer you:

  • Clarity on what really affects you and what can wait
  • Hands-on support: we are one team
  • Arguments and processes that convince other teams and management

Decision-makers and managing directors

Costs are rising, deliveries fall through, yet everyone only talks about new regulations?

What you can expect from me:

  • A clear financial view of risks and opportunities from new regulations and market shifts
  • Efficient prioritisation and a focus that speaks to your target picture
  • Efficient processes your team can carry on independently

Focus topics

Three areas, connected by a shared data basis, processes and business value

Each area stands on its own yet draws on the same data and responsibilities. That creates impact instead of duplicated work.

01

Risk management

01 Risk management

Making climate and biodiversity risks financially tangible

I identify and quantify physical and transition climate and biodiversity risks under TCFD/TNFD, CSRD and IFRS for own production, supply chains and entire portfolios. The results feed into sustainability reporting, risk management and investment decisions and are made tangible for boards and business units.
