Figure 6.4: Supply curves of conserved CO2 for commercial and residential sectora in 2020b for different world regions


a) Except for the UK, Thailand and Greece, for which the supply curves are for the residential sector only.

b) Except for EU-15 and Greece, for which the target year is 2010 and Hungary, for which the target year is 2030. Each step on the curve represents a type of measure, such as improved lighting or added insulation. The length of a step on the ‘X’ axis shows the abatement potential represented by the measure, while the cost of the measure is indicated by the value of the step on the ‘Y’ axis.
