The report has severe shortcomings, including:
The IPCC makes it look as if the temperature rise could be restricted to 1.5°C above pre-industrial and insists there was a carbon budget left, to be divided by using monetary analysis.
This narrative results in a failure to highlight in the SPM some key drivers of change (such as heat pumps in buildings and air taxis in transport) and in inappropriately referring to such key drivers of change as 'options', while failing to mention the best policies to achieve the necessary changes, i.e. through local feebates.
The image below, from the report's SPM, shows “options” by sector with the length of each bar indicating their potential for emissions reduction by 2030, while the color inside the bar gives a cost estimate.

These are not genuinely options, since the dire situation leaves little choice and instead makes it imperative to act most urgently, comprehensively and effectively on climate change, in line with the Paris Agreement.

The Climate Plan prefers local feebates. Where needed, fees can be set high enough to effectively ban specific alternatives.
