California adopts comprehensive strategy to meet federal ozone standard over next 15 years

Green Car Congress

The California Air Resources Board today approved a statewide plan for attaining the federal health-based standard for ozone, typically experienced as smog. The 2022 State Implementation Plan Strategy identifies the state’s control strategy for meeting the federal 70 parts per billion, 8-hour ozone standard over the next 15 years.

Study Concludes Warming Climate Will Increase Ozone Levels in Major California Air Basins; Climate Change and Regional Air Quality Are Intertwined Problems

Green Car Congress

Illustration of projected ozone changes in the South Coast region due to climate change in 2050. Areas in orange and red could see ozone concentrations elevated by 9 to 18 parts per billion. We already know that climate change will bring us increased forest fires, shorter winters, hotter summers and impact our water supply.

Argonne researcher using hydrous ethanol as a dual fuel to lighten the carbon footprint of locomotives

Green Car Congress

Hydrous ethanol (also sometimes known as azeotropic ethanol) typically ranges from 186 proof (93% ethanol, 7% water) to 192 proof (96% ethanol, 4% water). Earlier post.). It’s a good, fast way to adapt technology into an existing engine by manufacturing a retrofit kit that can be installed on current engines or on newer engines.

California ARB and NOAA Collaborating in $20M Research on Interaction of Air Pollution and Climate Change; One Atmosphere Approach

Green Car Congress

The California Air Resources Board (ARB) and the National Oceanic and Atmospheric Administration (NOAA) are collaborating in the $20-million CalNex research project to examine the nexus between air pollution and climate change. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.

Research shows clean fuel-use for ships off California coast extremely effective in reducing sulfur dioxide pollution

Green Car Congress

Data collected during a major 2010 state-federal atmospheric research project show that the first-in-the-nation regulation requiring ocean-going vessels to use clean fuel when near the California coast has been extremely effective in reducing sulfur dioxide pollution from ships, according to the California Air Resources Board (ARB).
