National Highway Traffic Safety Administration (NHTSA) Issues Report Stating Global Temperatures Will Rise 7 Degrees Celsius By 2100 And Reducing Emissions Will Not Help

 In Environment   Last Updated: October 6, 2018

In a report written by the National Highway Traffic Safety Administration (NHTSA) issued to support the freezing of “federal fuel-efficiency standards for cars and light trucks built after 2020,” the NHTSA writes that global temperatures will rise by 7 degrees Celsius and reducing or eliminating carbon emissions will not change this.  The report states:

The emissions reductions necessary to keep global emissions within this carbon budget could not be
achieved solely with drastic reductions in emissions from the U.S. passenger car and light truck vehicle
fleet but would also require drastic reductions in all U.S. sectors and from the rest of the developed and
developing world. in addition, achieving GHG reductions from the passenger car and light truck vehicle
fleet to the same degree that emissions reductions will be needed globally to avoid using all of the
carbon budget would require substantial increases in technology innovation and adoption compared to
today’s levels and would require the economy and the vehicle fleet to substantially move away from the
use of fossil fuels, which is not currently technologically feasible or economically practicable.

The United States recently became the only country to pull out of the Paris Climate Accords, which seeks to “strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.
