I posted this as a response to someone else earlier but I thought I'd add it as an action here. In my case, I want to reduce my use of car and plane transportation in general. I don't think this will mean daily bus rides, but fewer car trips, more walking and use of public transportation where possible. I went to LA for fall break to see my new grandson for the first time. That's a big carbon emission! However, we ONLY rode the bus for transport the entire time. It was only 23 minutes from LAX to my airbnb, quicker and easier than an Uber. The city of Santa Monica has an incredible, fast, clean, safe, low emission bus fleet. And, for people 55 and over, it is only $0.50! Regular price $1.25, still incredibly reasonable. I did think it ironic that I got a senior discount at a point in my life when I need the discount the least. We need to rethink senior discounts, as people over 55 and even over 65 have much higher incomes and wealth on average than the rest of the population. Maybe let it kick in at 70?
