In 2017, emissions from GHG emitting activities statewide were 424 million metric tons of CO 2 equivalent (MMTCO 2 e), 5 MMTCO 2 e lower than 2016 levels and 7 MMTCO 2 e below the 2020 GHG Limit of 431 MMTCO 2 e. Changes in emissions by Scoping Plan sector between 2000 and 2017. MMTCO 2 e (6%) from 2013 to 2017. Source: ARB.

In the first, they found that when fuel prices drove residents of São Paulo, Brazil, to mostly switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20%.

Added three major new retailers to the program in 2017, including a game-changing partnership with Kwik Trip which successfully rolled out E15 at 300 sites in just four months. The RVP of gasoline can range from 7 to 15 psi. The higher the RVP of a fuel, the worse its emissions are. Ethanol itself has a very low volatility: ~2 psi RVP.

Higher octane fuels can lead to higher compression ratios which in turn can lead to more efficient gasoline engines and reduced fuel consumption. With turbocharged gasoline engines, there is a double benefit: higher compression ratios and increased boost. Currently, the Clean Air Act limits the volatility of gasoline to 9.0

Paris and London have committed to launch their data online by the end of 2017. The RDE will only be fully in place by January 2021, and in its likely final version, real world NO x emissions are still expected to be more than twice the regulatory limit, and three times higher than for gasoline vehicles, the ICCT said.

Exhaust from modern gasoline powered engines, despite higher ignition temperatures than those powered by diesel, can be effectively treated for NO along with NMVOC (and CO) using a three way catalytic (TWC) converter. 85% is modelled to be emitted by the passenger car fleet based on the COPERT model and TRACCS database. —Karl et al.

Regarding future Greenhouse Gas (GHG) emission regulations (Pavley 2), staff is evaluating studies of the feasibility and cost of advanced technologies to reduce GHG emissions that could achieve widespread sales and acceptance in the 2017-2025 timeframe. Since gasoline vehicles emit generally at or below 1.0 PM Standard.
