<p>[quote user="Paul Milenkovic"] CO2 is perfectly harmless to human health whereas NOx has a bad influence, so if we save the Climate by improving fuel economy to reduce CO2, we will also increase NOx to kill more of us off, further reducing CO2 emissions?[/quote]</p> <p>I think both, greenhouse gas, particulate matter, and NOx reduction are equally important. As at least CO2 and NOx are contradiction you have to look for a balance. And that seems to be kind of a political question.</p> <p>The German Government had focus on CO2 reduction for a long time. Now the public opinion seems to change more in the direction of NOx reduction as their health risks are more often published.</p> <p>NOx is a direct health risk, climate change (CO2) can be a long term health risk.<br />Regards, Volker (Germany)</p>
