taxes are the most efficient instrument a govt can use. You decrease taxes for things you want to grow in consumption/use and you increase taxes for things you want to reduce production/consumption. Do you want faster transition to renewables and others from fossils? Increase taxes for fossil related stuff and decrease them for production & import of renewable related stuff. Same thing goes for electric cars, same things goes for electric/simple bikes. The only problem I see is low tax for artificial sweeteners. It would be nice to both limit the max quantity for sweeteners we know and limit the sweetness for all others to avoid high concentration of unknown stuff
