Every number in the row refers to this policy. Hover a policy name to see what it does.
How close to a voteiHow far the policy shown is from a council vote in this town. Ready for a vote: the town’s rules have been checked and one council vote would make the policy law. Checking the rules: promising, but the town’s or state’s rules still need to be confirmed. Long campaign: under a 40% chance of passing today, or state law limits what the town can adopt.
Climate impactiTons of greenhouse gas (CO₂ equivalent) this policy is expected to avoid over its lifetime, already discounted by the chance it passes, and including neighbors who copy it and state laws it helps pass. For scale, a typical car emits about 4.6 tons a year.
Est. campaign cost per ton eliminatediEstimated campaign cost divided by the tons the town itself would avoid (not counting neighbors or state laws). Lower is better. Towns on a long campaign are left out, since money spent there will not turn into a vote soon.
Chance of passingiThe model’s estimate of the odds the town adopts this policy, based on local politics, nearby towns that already adopted it and state support.
