Abstract

The invention relates to a method for determining an overall environmental performance indicator (6) of an object, in particular a motor vehicle (2), in which an initial overall environmental performance indicator (8) of the object is determined, which has been determined on the basis of a parts list (9) of components installed in the object, wherein each of the components is assigned an environmental component performance indicator, during use of the object, in particular operation of the motor vehicle (2), starting from the initial overall environmental performance indicator (8) and taking into account influencing data (10) determined during operation, the actual overall environmental performance indicator (6) is determined, and is triggered so that the actual overall environmental performance indicator (6) is output by means of an output device (5).

Description

The invention relates to a method for determining an environmental characteristic value of an object and to an electronic computing device for an object. From the KR 2024 0044396 A This is a known method for data processing and management using big data and artificial intelligence. Within this method, carbon emissions from commercial vehicles are measured and managed via mobile and cloud-based systems. The method utilizes an algorithm that collects and analyzes vehicle driving and energy consumption data in real time to precisely calculate carbon emissions. Furthermore, from the US 2023/0196234 A1 A method for improving the end-to-end CO2 footprint of electric vehicles is known. Furthermore, from the US 11 733 053 B1 A method for warning an operator of the effects of carbon dioxide is known. Furthermore, from the CN 111348045 A a quantitative display method for the carbon emissions of a hybrid vehicle and a vehicle is known. Furthermore, it is from the US 2023/0015077 A1 A method for estimating a motor vehicle's carbon footprint in real time is known. The carbon footprint can be estimated based on blockchain data. This blockchain data can record carbon emissions generated along one or more of the vehicle's energy supply chains. The estimated carbon footprint can be displayed via a user interface in a list of estimated carbon footprints, which are assigned to the respective charging or refueling stations. The object of the present invention is to provide a solution by which an owner of an object can be particularly well supported in keeping an environmental characteristic of that object particularly low. This problem is solved according to the invention by the subject matter of the independent claims. Further possible embodiments of the invention are disclosed in the dependent claims, the description, and the figures. Features, advantages, and possible embodiments set forth in the description for one of the subject matter of the independent claims are to be regarded, at least analogously, as features, advantages, and possible embodiments of the respective subject matter of the other independent claims, as well as of any possible combination of the subject matter of the independent claims, optionally in conjunction with one or more of the dependent claims. The invention relates to a method for determining an overall environmental performance indicator of an object, in particular a motor vehicle, especially a passenger car. Environmental technology encompasses all areas of technology that serve to preserve the environment and thus protect the environment. Environmental performance indicators can be used to evaluate the success or failure of such technologies. Such overall environmental performance indicators can, for example, be total energy consumption, a water footprint, or a carbon dioxide footprint (hereinafter also referred to as the CO₂ footprint). The method involves determining an overall environmental performance indicator for the product, which is calculated using a bill of materials listing the components incorporated into the product. Each component is assigned an environmental performance indicator. This bill of materials thus contains an individual environmental performance indicator for each of the numerous components that are, or could be, incorporated into the product. By using the respective environmental performance indicators of the components incorporated into the product when calculating the overall environmental performance indicator, the contribution of these components to the product's overall environmental performance indicator can be particularly well accounted for. The overall environmental performance indicator can therefore be determined with high precision by considering, and in particular adding, the respective environmental performance indicators of the components incorporated into the product. The overall environmental performance indicator can, for example, characterize the resources used in the product's manufacture, such as energy and/or water and/or the carbon dioxide produced and the resulting emissions. The overall environmental impact rating of the object can thus characterize how many resources have been consumed or how many emissions have been released up to that point. Point in time at which the item was made available for use in its new condition. The procedure further stipulates that, during the use of the item, particularly the operation of the motor vehicle, the actual overall environmental characteristic value is determined based on the initial overall environmental characteristic value and incorporating influencing data collected during use. The actual overall environmental characteristic value of the item thus takes into account the resource consumption and/or emissions of the item, characterized by the influencing factors considered, during its use. The determined actual overall characteristic value of the item therefore characterizes the value of the charact
