Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

The data shows a slight increase in overall emissions from the previous year, and a slight decline in emissions from transportation, which is the state’s main source of both GHGs and air pollutants. Per capita GHG emissions in California have dropped from a 2001 peak of 14.0

California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The state’s latest Greenhouse Gas Emissions Inventory shows that California emitted 429 million metric tons of climate pollutants in 2016—a drop of 12 million metric tons, or three percent, from 2015. They fell 23% from a peak of 14 metric tons per person (roughly equal to driving 34,000 miles) in 2001 to 10.8 The carbon intensity of California’s economy has dropped 38% since the 2001 peak and is now one-half the national average.

ICCT analysis finds real-world vehicle fuel consumption gap in Europe at all-time high of 42%

Green Car Congress

However, says Dr. Peter Mock, Managing Director of ICCT Europe, since 2001 Europe has seen the largest increase in its gap. Since 2001, the discrepancy between official measurements of vehicle efficiency and actual performance of new cars in everyday driving has more than quadrupled (from 9% to 42%)—a discrepancy that translates into €400 (US$465) per year in extra fuel costs for the average vehicle.

Will lighter cars backfire on industry?

Green Cars News

President Barack Obama’s national fuel efficiency standards in the USA have come in for criticism in The Wall Street Journal where a columnist points out that there could be severe costs in terms of urban air pollution and human life. Most people know about the positive effects of developing greener, lighter cars. However, could there be a downside too?

High Performance Computing key enabler for accelerating development of high efficiency engines

Green Car Congress

In an effort to reliably predict efficiency and pollutant emissions for new engines and fuels, computer simulations are used to study fundamental turbulence-chemistry interactions. Achieving these goals will require the transportation sector to compress its product development cycle for cleaner, more efficient engine technologies by 50% while simultaneously exploring innovative design space. diesel combustion by reducing temperature”, SAE Technical Paper 2001-01-0655, 2001.).
