Buildings efficiency is one of the most affordable ways to cut emissions

Residential and commercial buildings make up approximately 34 percent of the opportunity to improve energy productivity.

When compared to other sectors, the buildings sector has the largest unrealized potential for cost-effective energy and emissions savings

note:
‘Low cost’ emission reductions = carbon price <20 US$/tCO2-eq.
‘Medium cost’ emission reductions = carbon price <50 US$/tCO2-eq.
‘High cost’ emission reductions = carbon price <100 US$/tCO2-eq.
