Environmental aspects and sustainability are becoming increasingly important in the transport industry, which imposes the need to find alternative fuels that will contribute to the reduction of greenhouse gas emissions. Biodiesel produced from by-products of the food industry, such as grape seeds, is a sustainable solution that allows for waste reduction and at the same time contributes to the energy transition. The use of grape seed biodiesel supports the principles of the circular economy. This paper analyses the environmental potential of using grape seed biodiesel as an alternative fuel in the delivery vehicle fleet. The COPERT software, which is primarily intended for the calculation of air pollutants from road traffic, was used to analyse exhaust emissions from the delivery vehicle fleet. The results obtained from this research indicate the environmental potential of implementing biodiesel derived from grape seeds as a fuel for delivery vehicles.
