Whatever; they sent a letter - presumably to Trump - telling him to lay off their clean energy plan:
“We speak as a region of over 50 million people with a combined GDP of $2.8 trillion. There is no question that to act on climate is to act in our best economic interests. Through expanded climate policies, we have grown jobs and expanded our economies while cleaning our air,” the letter said.
The fact that Seattle and Portland are both mired in Democrat-created traffic gridlock that reduces vehicle engine performance and results in lower air quality seemingly escapes them.
“One percent of U.S. emissions are associated with Oregon and U.S. is maybe 15 percent of worldwide. So even if we had aggressive policies that were very effective that’s not going to make a big dent,” said Grant Jacobson, a public policy professor at the University of Oregon.
This is a map of diesel emission concentrations in the Portland-Vancouver area; the marker covers zip code 97219, and like other parts of the city near downtown, it receives high levels of particulates from diesel powered vehicles. That's in no small part due to the fact that Democratics have worked assiduously to increase traffic congestion rather than alleviate it. It's one thing to claim in a letter that they've been cleaning our air, but the facts don't support their boast.
