Strange that CO2 has become the only “pollutant” discussed. A non toxic gas that we exhale with every breath. Plants convert it back to oxygen which makes the human avarice driving deforestation unbelievably idiotic. Sf6, a gas used as an electrical insulator in the wind turbines, power stations etc that charge the Green phev,ev revolution is 23500 times more powerful as a greenhouse gas A metric ton of concrete emits @900 kgs of CO2 in production, steel 1800 kgs. How much is needed for HS2 or new roads and houses for the 6 million increase in our population since Blair opened the floodgates? The Chinese have been building a new coal fired power station every 1 to 2 weeks, dwarfing the west’s efforts. The pollutants that are ignored by the press include the carcinogenic soot emitted by diesel, DPFs are not 100% efficient and there are still too many older cancer wagons on our roads. Then there are toxic NOx, sulphurs and benzine. Urea, cuddly name Adblue, reduces but not eliminates them. CO2 might be heating our planet, but real urban vehicle pollution gives kids asthma or worse. As others have said, the best contribution we can make is to drive efficiently and less often.
