If you look at the financial interests threatened by environmental regulations, you will find the largest national corporations spending hundreds of millions against those regulations.
Their opposition falls under the phrase “fewer government regulations.”
Catalytic converters have proven to be reliable and effective in reducing noxious tailpipe emissions. However, they also have some shortcomings in use, and also adverse environmental impacts in production:
- An engine equipped with a three-way catalyst must run at the stoichiometric point, which means more fuel is consumed than in a lean-burn engine. This means approximately 10% more CO2 emissions from the vehicle.
- Catalytic converter production requires palladium or platinum; part of the world supply of these precious metals is produced near Norilsk, Russia, where the industry (among others) has caused Norilsk to be added to Time magazine's list of most-polluted places.[33]
- Pieces of catalytic converters, and the extreme heat of the converters themselves[34], can cause wildfires, especially in dry areas [35][36][37]
