Why you should measure your carbon footprint
More and more businesses are measuring their CO2 emissions. Why? Because it’s not just good for the climate, but also for your business. Whether you are required to report by law or want to strategically leverage your sustainability efforts, understanding your company carbon footprint is an essential first step.
Legislation and reporting obligations
While the reporting obligations of the CSRD have been postponed for many companies, the expectations haven't disappeared. Large clients are already asking their suppliers to share their CO2 emissions data. This includes SMEs that are not (yet) legally required to report.
A carbon footprint calculation helps SMEs get ahead of these requests and prepare in time for future regulation. It is a smart move to remain relevant, credible, and competitive in a changing market.
Improve brand image and sustainability strategy
In addition to compliance, measuring your footprint provides a reputation advantage. Customers, partners, and investors are increasingly paying attention to the sustainable choices you make. Transparency about your emissions shows you take responsibility.
What data do you need to calculate your company carbon emissions?
A carbon footprint calculation is not guesswork. You need data on your business activities and must link it to recognized emission factors.
Activity data
This includes:
Electricity and gas consumption (kWh, m³)
Number of kilometers driven with lease cars or flights
Fuel consumption in liters
Materials or raw resources used
Employee commuting

Getting started yourself is great, but watch out for these pitfalls:
