The automotive industry’s contribution to global greenhouse gases (GHGs) – broadly speaking – takes two main forms. First, there’s the contribution of road transport – passengers and freight – that is related to economic activity, the end-use of the auto industry’s products. The UN’s IPCC estimates that the transport sector as a whole accounts for approximately 23% of total energy-related CO2 emissions. The IPCC also argues that there is a danger that transport emissions could increase at a faster rate than emissions from other end-use sectors as per capita transport demand accelerates.
