Environmental impact monitoring system and method therein for estimating an environmental impact of transporting items of goods

An environmental impact monitoring system for estimating an environmental impact of transporting items of goods, wherein the environmental impact monitoring system comprising a processing circuitry and a memory, wherein the processing circuitry configured to

• determine an environmental impact associated with each of a number of items of goods for a corresponding transport of said item of goods, wherein each environmental impact is based on a part of a total energy consumption of a vehicle for the corresponding transport that has been assigned to said item of goods, and wherein the total energy consumption for each of the corresponding transports are measured by the vehicle whilst carrying out the corresponding transports, obtain a first set of variable environmental transport factors which impacted the total energy consumption by the vehicle whilst carrying out each of the corresponding transports, and estimate an environmental impact associated with a subsequent item of goods for an upcoming transport of said subsequent item of goods based on the determined environmental impacts and the obtained first set of variable environmental transport factors.
