The Cool Cities Pledge, originally called the
U.S. Mayors Climate Protection Agreement,
states . . . C. We will strive to meet or exceed
Kyoto Protocol targets for reducing global
warming pollution by taking actions in our own
operations and communities such as 1. Inventory
global warming emissions . . . 2. Adopt and
enforce land-use policies that reduce sprawl,
preserve open space, and create compact, walkable
urban communities 3. Promote transportation
options such as bicycle trails, commute trip
reduction programs, incentives for car pooling
and public transit . . .
