Carbon Footprint Methodology for Automotive Products - how to calculate the carbon footprint?
The carbon footprint methodology for materials, components and vehicles has been established, which lays a foundation for the carbon footprint accounting. Currently,
there are two major problems to be figured out: one is to solve the uncertainty of existing ISO standards, and the other is to solve the problem of inconsistent
accounting methods.
Material production
Evaluate the environmental impact of "cradle-to-gate" raw material production
(including extraction and processing of raw materials and production of auxiliary
materials)
Fuel and electric power production
Evaluate the environmental impact from
the source of primary energy to the
distribution point (such as charging
station)
Define the accounting method of life
cycle (from cradle to grave) carbon
emission from automotive products.
Parts production
Evaluate the environmental impact of "gate-to-gate" parts production (including
injection molding, stamping and welding)
Vehicle cycle: carbon emissions from
vehicle production, maintenance and
end-of-life activities.
Fuel cycle: carbon emissions from
the consumed fuel and the production
and use of energy
Vehicle production
Evaluate the environmental impact of "gate-to-gate" production of vehicle
products (stamping, welding, painting, assembly and power station building)
Utilization /operation
Environmental impact of driving
Impact of repair and maintenance
End-of-life recycling
Add the environmental impact assessment (EIA) of
end-of-life activity scenario (i.e., to the grave). It may
include recycled materials, energy recovery and
landfill treatment
