1. Vehicle Manufacturing:
• Gather data on the materials used in the car's manufacturing, including steel, aluminum, plastics, and electronics.
• Determine the carbon emissions associated with extracting and processing these materials.
• Include emissions from the manufacturing processes, such as stamping, welding, painting, and assembly.
2. Vehicle Use:
• Calculate the lifetime fuel consumption of the car based on its fuel efficiency and average annual mileage.
• Convert fuel consumption to carbon emissions using the fuel's carbon content and combustion efficiency.
• Consider emissions from engine operation, including both exhaust emissions and evaporative emissions.
3. Maintenance and Repairs:
• Estimate the carbon emissions associated with regular maintenance and repairs throughout the car's lifespan.
• Include emissions from producing and transporting replacement parts, as well as energy used for servicing.
4. End-of-Life:
• Determine the methods of end-of-life management, such as recycling, dismantling, or landfilling.
• Calculate carbon emissions associated with these processes, including transportation and energy consumption.
By adding up the emissions from each stage of the car's life cycle, you can estimate the whole life carbon emissions of the car. It's important to note that the specific emissions may vary depending on factors such as fuel type, vehicle size, and regional energy sources. To ensure accuracy, you can refer to life cycle assessment studies or use standardized methodologies for calculating carbon emissions.
