COP21 to avoid Border Adjustments Tax
COP21 aims to bring every nation on a path to net-zero. This way, no border adjustment carbon tax would be needed between countries.
COP21 intended to avoid any carbon border tax adjustments, i.e., custom tolls, to prevent dirty foreign competition from beating courageous domestic corporations going green.
COP21 was only an easy first step, with minimal carbon reduction targets. More ambitious steps must follow, but their negotiations are currently bogged down in the COPs following COP21.
