Four times as many emissions? Compared to twenty years of someone using a Diesel engine daily. I doubt that is true.
….quick reading online…..they talk about localised contamination, water waste ….stuff like that. I think your info is a little misleading.
Anyhow. That doesn’t excuse people using diesel and petrol engines. Use a bike, public transport.
Stop making the planet unliveable for my daughter and her daughter. Or at least try. Please.
