If all goes right, you will have NO pollution by the second night. After this all you need to do is to intercept jeeps with careful setups of flamers and guns
At level 5, keep your truck two, and on natural gas. Invest in natural gas power and nukuler, and have zero pollution policy. No farms since you wont starve in 3 days, extract metal like crazy, and if possible, upgrade plants, and keep a healthy perimeter of teslas to intercept charging zombie jeeps. The walking ones are incinerated anyway. keep flame turrets only around the fort for emergency as fuel supply is short
Actually there ARE solar cars. Just look at your fuel options. Garbage trucks can be driven on Oil,LPG,Electricity and Ethanol
Also, using Ethanol is EXTREMELY stupid as it takes a load of smog and power to raise crops, and then ALSO more smog to burn it in trucks.
Overly complicated? Seriously, all you do is to choose an energy path in the map that is most feasible and build up. If you cant handle smog, thats your problem. I get to 0 Smog even in hard mode which simple makes zombies less than babies.
