“With the software of Carbon+Alt+Delete we are not only compliant with the standards, but the data part within the tool is yearly updated and gives us the opportunity to manage our own data very well. It is very clear that there is a high focus on transparency, traceability and compliance. Adding the scenario simulation and SBTI target setting to that makes it a very performant tool.”

- François Aze

It’s often the case that carbon accounting software works well for clients, but not for consultants as it lacks detail and flexibility. Carbon+Alt+Delete is the first tool tat clearly focuses on consultants. At the same time, there is enough detail to share with clients, supported by clear visuals. This combination makes it a very strong tool for us to support our carbon service offering. We’re very positive of our partnership with CAD, we’re constantly keeping in touch so we can grow together and bringing more and more on board. “
