- we will need VASTLY more energy in the future
- the amount of CO2 we pump into the atmosphere is a big problem - both AGW and biogeochemical effects
- so we have to decarbonise the energy supply, aka reduce carbon intensity C output / energy consumed (see Kaya identity section for more detail here)
- decarbonisation makes sense from other perspectives too, eg. energy security for some countries (from a policy perspective it is important that there are some short and intermediate term gains from the pain or costs of policy)
- the public will not accept a big C tax designed to change energy consumption behaviour - they will vote out any party that introduces it
- small steps are better than grandiose plans that end up being rejected
- there is not a linear relationship between climate science and government policy, Scientific findings in complex social issues do not dictate policy. Politics in a democracy requires public support. A non linear or oblique approach might work. The direct approach has failed (Copenhagen)
- the public will accept a small dedicated C tax (rising slowly over time) to fund R&D; there is consistent public support for some action on climate change but not dramatic action which will alter standard of living
- We need more R&D because present technology is not sufficient to do the CO2 reduction that is required – taking into account future economic growth and removal of CO2 from the ocean to reduce harmful biogeochemical effects, as well as from the atmosphere
- Since the above steps do not provide a guarantee for targeted CO2 reductions then a backstop is also required
- CO2 air capture and storage (remediation) is a potential backstop, which could reshape the climate debate, one of the targets for further R&D
