Putting the squeeze on soot

Running diesel engines and gas turbines at high pressure to boost power output and efficiency is harmful for the environment. Burning fuel at high pressure can significantly change the soot particles that are produced, William ...

The fight for clean emissions continues

It is exactly 20 years since experts from Empa and VERT published the first test results on diesel particle filters. Today, more than 300 million vehicles worldwide are fitted with such filters. However, a VERT conference ...

Your wood stove affects the climate more than you might think

Norwegians love to heat with wood. The walls of houses around the Norwegian countryside in the winter are lined with stacks of wood and smoke rises from chimneys, especially on cold days. There was even a national "wood night ...

Estimates of diesel soot pollution will help Arctic environment

Engines that burn diesel can spew a large amount of pollution containing soot particles. These particles have an impact on health and climate in some of the world's most sensitive regions. Researchers at Pacific Northwest ...
