It’s just so hard to know what actions have what impact on CO2 production. Some are high-pain, low-gain (switching devices off instead of standby?), some are opposite (cycling instead of driving when possible etc). For that if for no other reason, I’d rather if consumer prices included an explicit CO2 tax. The here can be a rebate for poorer people, or personal allowance, whatever, but there would be a fixed yardstic…
That'll help (the oil companies).
