We help companies navigate the ESG jungle and position themselves to be resilient and future-ready – since 2013.

Lost in the ESG jungle?

Want to get started, but uncertain about how to begin?

Many mid-sized companies find themselves exactly in this situation. External pressure is increasing noticeably: customers, banks, and authorities are demanding robust evidence such as CO2 data, net-zero roadmaps, climate risk analyses, and sustainability reports. These requests often arrive unexpectedly and with tight deadlines, putting companies under pressure.

Even those that recognise the competitive advantage of ESG and want to take action often face challenges, with a lack of time, manpower and know-how often being the main issues.

Do any of the following sound familiar?

  • Missing or incomplete data
  • Complex calculation methods and standards (e.g. GHG Protocol)
  • No internal resources or expertise
  • Unreliable tools or Excel chaos
  • Fear of reputational risks due to errors
  • Uncertainty about what is truly “certified” or “effective”
  • Lack of transparency around Scope 3 emissions
  • No clear roadmap for reduction and compensation
We are here to help

How we take the pressure off your shoulders

Instead of launching yet another complex ESG mega-project that ties up valuable internal resources, we rely on a clear, structured, and pragmatic roadmap. Our goal: within just 90 days, you will have a robust ESG and CO2 foundation that meets both regulatory requirements and market expectations.

  • Structure instead of chaos
    We help you build a lean but effective system: clear roles, centralized documentation, and defined processes – exactly what small- and mid-sized companies need.
  • Clean data collection with plausibility checks
    Together, we collect the relevant CO2 and ESG data, identify data gaps, and clearly distinguish between measured values, estimates, and assumptions.
  • Calculations based on recognized standards
    Your CO2 footprint is prepared in line with international standards (e.g., the GHG Protocol), fully documented, and robust enough to withstand critical scrutiny.
  • An experienced team instead of costly internal build-up
    You benefit from the expertise of specialists who have successfully implemented ESG and CO₂ projects in SMEs numerous times, without having to build expensive in-house ESG expertise.
  • Clarity in the label and certification jungle
    We help you understand which certifications, ratings, climate projects, and compensation solutions are truly meaningful – and which ones you can safely ignore.
  • Making Scope 3 understandable
    We show you where your material Scope 3 emissions lie, how to capture initial metrics with reasonable effort, and how to build transparency step by step.
  • A clear thread from measurement to action
    Data turns into a real roadmap: clearly prioritized targets, concrete reduction measures, and high-quality compensation aligned with your business model.


We support you in calculating your CO2 emissions in a straightforward and transparent way, in line with international standards. This enables you to build trust with investors, customers and partners, and implement genuine climate protection measures effectively.
