Taiwan plans to launch an emissions trading system (ETS) in 2028 as the next phase of its carbon pricing framework — a cap-and-trade market where companies buy and sell permits to emit greenhouse gases. However, environmental researchers and academics caution that the experiences of Japan, South Korea, and the European Union (EU) show that emissions trading markets take years to mature and operate effectively. With Taiwan's own carbon fee only recently taking effect, they argue the government should prioritize policy continuity and give businesses time to internalize carbon costs and implement decarbonization strategies before introducing a cap-and-trade regime.

Taiwan's carbon fee system has begun collecting payments, with the first batch covering 240 high-emitting companies across 461 factories and generating NT$4.97 billion (US$156.07 million) in initial revenue. Taiwan also plans to roll out an emissions trading system (ETS) in 2028, initially targeting 20 major emitters in the steel, cement, and semiconductor sectors.

Japan and France are moving to reduce their reliance on Chinese heavy rare earths, backing a recycling project in southwestern France that is expected to supply materials used in high-performance permanent magnets for electric vehicles, defense equipment, aircraft and wind-power motors.
