*The numbers created under the 鈥渂usiness-as-usual鈥 scenario depict such a scenario without drastic deviations in technology advancement or policy-making from past episodes. While there is typically still some technological progress in the form of reducing emissions intensities (stemming e.g. from energy efficiency gains) that are partly a result of policy actions, this scenario does not take into account announced policy pledges or the like.
