We do a calculation every year. We started doing this in 2013, so we have been doing this for 10 years now. The year 2021 we started very carefully to consume BLUE diesel in some cars – namely the small diesels we have, a passenger car and a van. At first this was 30% blue diesel; that is, 70% mineral diesel and 30% diesel of vegetable origin. This was because we had no idea how that was going to turn out and whether our diesel would run well on it.
At the end of 2021, we then received an accounting from the manufacturer based on liters filled. As a result, our small diesel engines emitted 27% less co2 and on the total CO2 emissions the reduction was 4%. In the year 2022, our trucks started running on blue diesel (100%). This is of vegetable and not fossil origin. In this calculation we assume that driving on plant-based fuel gives a co2 reduction of 90%. Furthermore, the use of 104 solar panels has reduced co2 emissions due to lower electricity consumption. Also, two fossil-based luxury cars have been replaced by electric models. Compared to a few years ago, our co2 emissions have fallen by more than 80%. So we have already met the 2030 Paris environmental targets. On this page you see only a summary of this calculation. On request we will send you the full calculation with explanations.
