Fair, it’d be worth doing some math on this. Let’s assume a scooter Travels distance T on a full battery (across multiple trips of course) and has efficiency TE based on the efficiency of the (presumably fossil fuel) power plant and that the person picking it up for Charging drives distance C Picking Up PU scooters with a fossil fuel engine that has CE efficiency. Of course, we need to assume that TE and CE are measured in miles/kg-of-carbon-emission. So, the full equation would look something like:

(TPU/C)(TE/CE) = Carbon Efficiency of using Lime/Bird

I’ll admit that I don’t know all the numbers to plug in here (being HN, maybe someone else does) but given that even dirty power plants have better fuel efficiency than ICEs and that chargers don’t need to drive super far to find a ton of scooters my money is on this being better than driving, carbon-wise.
