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).<p>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.<p>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.<p>Newspaper articles only help a little, they usually present an incomplete picture, and optimising against an incorrect utility function is often counterproductive.<p>I’m imagining something like VAT, where “value added&#x2F;carbon” adds up over the lifetime of product&#x2F;service production.
