Thus, the phase change of water from liquid to gas, after absorbing photons, is a feedback, the absorption of photons and the emission of photons atmospheric water vapor is a forcing, but the photons released when gaseous water become liquid water is a feedback.

Increased efficiency is achieved by means of a longer trading period (8 years instead of 5 years), a robust and annually declining emissions cap (21 % reduction in 2020 compared to 2005) and a substantial increase in the amount of auctioning (from less than 4 % in phase 2 to more than half in phase 3).
