"An excelllent yardstick for this is steel. Whether in your car, your house, your home, your public transport systems or hospitals or schools, the quantity of steel embedded in your life is as good at illustrating economic developments as GDP statistics , if not better. If you live in Europe or the US you have, on average, up to 15 tonnes of steel in your world. In China the average is up to 7 tonnes; most people in Africa have an average of less than one tonne.
Let's say we in rich countries stop growing and keep our steel quotient where it is. Fine. But who are we to dictate that the people of Africa cannot aspire to have the same steel per capita as those in rich countries? The sting in the tail is that we still have no way of mass-producing virgin steel without emitting a lot of carbon and using tonnes of, guess what, coking coal.
Now, all of this may read like a counsel of despair, and such points have occasionally been trotted out by fossil fuel lobbyists to damn green technologies. But no: net zero is not impossible. It's just a lot more complicated than many people would have you believe. Take those wind turbines: yes, they are made in part from oil, but over their lifetime they save the carbon emissions from their manufacture many time over in the form of green energy. Same for solar panels.
In time we will, with luck, perfect truly green steel, concrete and batteries (as well as getting a lot better at recycling the old ones). But we're nowhere near that yet, and there's no point in pretending otherwise."
I find it is usually better to read an article before criticizing it.
