A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

GSMA study indicates Bangkok could gain US$1B per year in benefits through ITS; reduced travel time, CO2 emissions and accidents

Green Car Congress

In addition, CO 2 emissions contributed by road traffic could be reduced by 10-20%, or 3 to 5 million metric tonnes per year. GSMA estimates that reductions in travel time, CO 2 emissions and road accidents through ITS could result in economic benefits worth up to $1 billion per year for Bangkok alone. hours travelling to work per day.
