TCI Regional Policy Design Stakeholder Submissions

Thank you for your 9/16 webinar. I have two questions.
1. One speaker contrasted the TCI approach with “carbon pricing just to raise revenue”—as if putting a price on carbon were nothing but a carbon tax, à la proposal from president Macron that filled the streets of France with angry people in yellow vests. That’s setting up a straw man, and it’s not helpful.
Instead, I’d like to hear from Massachusetts government officials who favor the TCI approach whether they think that reducing emissions from transportation only will get us to overall emissions reduction goals more effectively than an economy-wide Carbon Fee and Dividend program, and if so, how.
2. I had a question that evidently others submitted as well, but alas, I didn't understand the answer. Perhaps it could be addressed again in the Sept. 29 webinar. I understand there's a mechanism to contain rising costs (in dollars), but will goals for reductions in emissions still be met if that mechanism is triggered? I heard nothing about mechanisms to ensure that current emissions costs to health and safety are contained and reduced.
Thank you again for your work on the TCI and your efforts to educate the public.
