Climate change: IPCC report is 'code red for humanity'
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 yardstick for measuring your personal impact.Off the top of my head, I have no idea which if my activities generates the most CO2. My car? Energy use? Diet? Going skiing once a year? No idea.Newspaper articles only help a little, they usually present an incomplete picture, and optimising against an incorrect utility function is often counterproductive.I’m imagining something like VAT, where “value added/carbon” adds up over the lifetime of product/service production.
