Generally government regulations like this are going to make things more expensive, not less. So these types of regulations actually give poor people fewer options. For example, the Dodge Journey was not available in California in 2020 due to emissions regulations. This is objectively worse for poor people, since it gives them fewer options. If taxing negative externalities causes significant cost to people who can't afford it, I'm all for subsidizing some amount of that though.
