Focusing on those, rather than trying to quantify, the emissions, released, is much easier. It’s much easier for me to know how much I buy then to try to find out how much admissions are omitted between the things I buy.
For example, trying to figure out the emissions created by buying a Tesla for a high mileage, gas powered car. What really matters most? The best answer is buying neither of them. Second best sensor is buying and driving it much less, those both matter more than how much admissions are created by the creation or use these vehicles.
They still arguing about how much emissions are caused by elect versus high-efficiency, gas, powered vehicles. In fact, we have something that easily quantifiable versus something that’s almost unquantifiable.
We all just need to do a lot less. But that’s why people focus on emissions and not use, because it’s the thing they don’t want to hear.
