Hi. This scenario uses HR763 carbon pricing, stops new coal, oil, and gas infrastructure, does high subsidies for renewables, and reduces methane, etc gases somewhat. This gets to 2.1 degrees. With exception of carbon removal through technology, the remaining levers have no or little impact. Can someone help me understand why? Thanks!
With this scenario it looks like global energy is very low carbon and that was achieved quickly with the ban on new fossil fuel infrastructure. So changes thereafter in population, GDP, energy efficiency and electrification do not affect the energy mix but simply reduce overall demand which is being supplied by renewables and nuclear and bioenergy. There is still room to tax bioenergy and reduce methane further. What is missing is carbon removal - afforestation, reduced deforestation, and new CDR technology.
