You know what else would offset 8,000 cars? Short-range, low speed, autonomous minibuses that move people on demand from their homes to multi-mobility nodes. These nodes would then be connected together by premium mass transit, whether Bus Rapid Transit, Light Rail, heavy rail, or MAGLEV. That, and 15 minute cities where most people don’t have to travel that far for daily needs. We need the mesh network of new innovative mobility to bridge the gap to hub-and-spoke traditional mass transit.

True that, but afterwards we will need to remove the existing CO2 in the air to return the climate back to normal. Mass transit is definitely the most effective way to prevent cars from impacting the environment, I was just using cars as a unit of measurement for CO2.

Sure, but if we don’t need all the land we’re currently using for parking, we can build a lot of new infill mixed-use housing that’s built of fast growth biomass materials (compressed laminated timber, bamboo, pine, hemp) that are all sequestering carbon while lowering the average person’s carbon footprint. Figure out mass adoption of plant, fermented, or lab-grown protein, and we’re well on our way to tackling climate change.

I figure this buys us enough time to get to orbital solar-based energy with panels made largely from materials mined on the moon.

I dont think wood biomass sequestration can reach the scale we need to remove significant amounts of CO2 compared to algae. Wood also releases carbon dioxide as it decomposes over time, it would need to be pyrolyzed for a more long term form of sequestration.
