A story in CQ Weekly (“The Greening of the Wheels”) looks at the vehicle leases taken out by members of Congress and a little known provision in the energy policy act passed last year that says members may be reimbursed for leasing vehicles only if the vehicles have relatively low levels of greenhouse gas emissions. Apparently lawmakers haven’t been too concerned with vehicle emissions in the past when they’ve been shopping on dealer lots: Two-thirds of the cars at members’ disposal will have to be replaced when their leases are up, according to the story.
