The easiest thing we could do immediately is to produce fermented 100% bioethanol (petrol), retune cars, trucks and ships to burn it clean. (aircraft need more caloric fuel) This only solves emissions and not completely.

Electric powered by uranium and renewables solves more and is also immediately feasible though expensive to build infrastructure for battery handling.

Second thing would be to disperse industry and farming more evenly so that we do not have to transport food long distances. Remove energy intensive packaging (cans and bottles - use dispensers or foil), replace lighting with most efficient available. Switch manufacturing to as much on demand as possible.
