Various organisations are currently collaborating to investigate how Ecotest can help companies to improve their performance regarding CO2 emissions and sustainable and responsible entrepreneurship. . In order to reach the high levels of performance, it is particularly important for a company to have very good quantitative insight into its own value chain, so that concrete improvements can be identified and implemented, and CO2 savings can be achieved. The parties involved in the discussion are active within the services industry and infrastructure construction. This indicates that Ecotest can be of value for companies throughout the chain. The results of the study will soon be announced.
