Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

Third, they used estimates of the fuel price elasticity of light-duty vehicle fuel economy and a lagged adjustment model to estimate the effects of gasoline prices on mpg from 1975 to 2018 in the absence of fuel economy and GHG regulations. Again, because of the uncertainties in the attribution they conducted a sensitivity analysis.

EEA: average CO2 emissions from new cars and new vans in Europe increased in 2018

Green Car Congress

According to provisional data published by the European Environment Agency (EEA), the average CO 2 emissions from new passenger cars registered in the European Union (EU) in 2018 increased for the second consecutive year, reaching 120.4 g CO 2 /km in 2018. Vans registered in the EU and Iceland in 2018 emitted on average 158.1

Moreover, the average mass of new conventional cars, excluding SUV, increased by around 22 kg from 2018 to 2019. In 2019, as in 2018, gasoline cars were the most sold passenger vehicles, constituting 59% of all new registrations. CO2/km, which is about 7 % above the 2020 target of 147 g CO 2 /km. g CO 2 /km.

CARB: ridesharing vehicle fleet CO2/PMT in 2018 approximately 50% higher than the statewide passenger vehicle fleet average

Green Car Congress

The California Air Resources Board (CARB) has released the 2018 Base-year Emissions Inventory Report , as required by Senate Bill 1014 (SB 1014, California Clean Miles Standard). The 2018 average fleet occupancy for the TNC industry is 1.55 (an average of the occupancy in “pooled” and “non-pooled” rides) passengers. Earlier post.)

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

In the new study, we have analyzed 20 years of aviation emissions, up until and including 2018. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000–2018. For 2018 the net aviation ERF is +100.9 —Marianne Tronstad Lund, co-author. mW (mW) m ?2 Pitari, M.J.

in 2018, the only annual increase in the past five years. The changes in US energy-related CO 2 emissions in 2019 offset the increase in 2018. In 2019, the transportation sector’s energy-related CO2 emissions declined by 0.7% US energy-related CO 2 emissions declined by 2.8% CO 2 emissions had increased by 2.9%

to 33 Gigatonnes (Gt) in 2018. These findings are part of the International Energy Agency’s latest assessment of global energy consumption and energy-related CO 2 emissions for 2018. Electricity continues to position itself as the “fuel” of the future, with global electricity demand growing by 4% in 2018 to more than 23,000 TWh.
