The key part is:&lt;p&gt;&amp;gt; A series of studies by Tsinghua University, whose alumni includes the incumbent president, showed electric vehicles charged in China produce two to five times as much particulate matter and chemicals that contribute to smog versus gas-engine cars. Hybrid vehicles fare little better.&lt;p&gt;Producing particulate matter 50 miles away from a city is not remotely the same as producing it 2ft from a pavement. I&amp;#x27;m not sure about smog, though, is the effect regional or local?</text><parent_chain><item><author>brownbat</author><text>EVs in China produce two to five times the amount of smog as gas vehicles, because the supporting energy mix is so dirty.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.scientificamerican.com&amp;#x2F;article&amp;#x2F;in-coal-powered-china-electric-car-surge-fuels-fear-of-worsening-smog&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.scientificamerican.com&amp;#x2F;article&amp;#x2F;in-coal-powered-c...&lt;/a&gt;&lt;p&gt;Should be good long term, if China realizes other energy sourcing goals, just...
