Diesel cars pollute higher in cold weather, says report

A new report by Emissions Analytics said toxic emissions from diesel cars are much worse than dreaded when temperatures fall below 18°C.

Indicating that usage of diesel vehicles given the climate, post severe danger to human health and the environment, the report, which investigated 213 models across 31 manufacturers revealed that the problem is caused by engine management systems installed by manufacturers, which are designed to partially switch off emission controls when it gets cold outside.

According to the report the development protects the engine against extreme temperatures and boosts miles per gallon, but leads to higher emissions that are linked to thousands of deaths in across the world every year.
Air pollutions such as the emissions release from vehicles according to report by the American Association for the Advancement of Science (AAAS) kill at least more than 5.5 million people yearly.

Successive governments in Nigeria have been accused over negligence towards curtailing emission issues.
New report published by the World Health Organization (WHO) earlier in the year stated that four of the 20 cities with the worst air quality recorded in the world were in Nigeria.

The commercial city of Onitsha, Anambra State ranked as the world’s worst city in terms of air quality in measure carried by examining the yearly mean concentration of particulate matter (PM10) in nearly 3000 cities across the world.
