These are from an environment campaign writing, and I know they belong to conditional2(counterfactual or unlikely), but I have to explain to my students if they belong to either counterfactual present(or general time) or unlikely future.
Whenever I see this kind of conditionals, I'm confused if it is counterfactual present or unlikely future. I realized there's no unlikley present, so please don't blame me. I just want to know if it is about the present(general time) or the future. Your kind answer will be highly appreciated.
1)If we reused one million more pounds of newspaper, the trees we would save could absorb 125,000 pounds of CO2 per year....
2)If one million people reused or just upgraded their computers, we would save 265,000 tons of fossil fuels....
3)If one million people used appliances with Energy Saving Labels, we would eliminate about 5.6 million tons of CO2 per year.
It depends on the context. They could be either.
Context is always important; labelling is rarely important.
