Comparison

Excel, consultant or Climactra?

Three paths to a hotel carbon inventory side by side. With an honest assessment of the strengths and weaknesses of each option.

Before deciding on a solution, a direct comparison is worth the time. Excel is free but error-prone and gives no score. Consultants deliver quality but cost €3,000–€10,000 per year. Climactra sits in between: methodological rigour, consistent reproducibility, fair price — plus everything Excel and consultants cannot do (score, readiness, measure simulation).
