Milovanoff, A., Posen, I.D. & MacLean, H.L. Electrification of light-duty vehicle fleet alone will not meet mitigation targets. Nat. Clim. Chang. 10, 1102–1107 (2020)

Objective:

• Develop a backcassting exercise to analyse the energy and resource implications for the US LDV fleet remaining within sectoral CO2 emissions budgets consistent

Case:

• US

Methodology:

• SSPs: GCAM
  • LDV fleet: FLAME model

Data Source

• EVs and socioeconomic

Findings:

• Current policy and electrification targets are insufficient to remain within a suitable US LDC CO2 emission budget consistent with a 2$^circ$C target
• Under BAU scenario, up to 351 million EVs need to be on the road in 2050 or up to 90% of the on-road LDV fleet to remain within a suitable CO2 emission budget

• A fleet of 350 million on-road EVs in the US could imply an annual electricity demand of up to 1730 terawatt hours TWh (41% of the annual national electricity generation)

• The volume of the carbon footprints of MNEs invested by developed countries was greater than the volume of their territorial emissions induced by foreign-owned enterprises, with the opposite findings for developing countries
• Chinese mainland has the largest net negative balance of embedied emissions in supply chains of MNEs
