Question and Proposed Answer

Q. What will be the most important technological development over the next 10 years that will have the greatest impact in reducing climate change risks?

A. RE<<C and IPCC Scenario Compression

180-Word Summary with Key Slides

In 2016, we reached the milestone where renewable electricity (wind and solar photovoltaics) became cheaper than coal. In the terminology of the old initiative, we achieved RE<C.

By 2026, renewables will become much cheaper than coal: RE<<C.

This has profound implications for reducing climate change risks, because it means that renewable electricity will become the business-as-usual path, even in the absence of climate policy. (To a large extent, it already has.)

Current IPCC RCP (representative concentration pathway) models were developed before we achieved RE<C, so they still assume high coal use in 2100. As RE<<C arrives and IPCC scientists gain confidence that ours will be a low-coal future, the range of IPCC scenarios may compress towards lower-emissions pathways which correspond with still-severe but less catastrophic levels of global warming.

If and when this happens, RE<<C and IPCC Scenario Compression would provide an inspiring “win” for global citizens and policy-makers to rally around, to catalyze further progress. It would also affirm the power of ethical ideals and entrepreneurial zeal to effect positive change against even the most daunting of problems.
