Let’s start by banning A/C in ALL gov buildings and vehicles.
And don’t forget to reduce the funds for them as well.
See how long that lasts.
Ban, heck.
Be more proactive.
A 4-lb sledge, and a 2 foot construction stake would do the trick nicely.
That way, none of our .gov Masters would have to lie awake nights worrying about their personal contribution to "global warming"...
