Housing & Buildings

Buildings account for almost 40% of carbon dioxide emissions globally, and in bigger cities up to 80%. Many cities have turned to retrofitting buildings as one of the most costeffective ways to make good on promises of greenhouse gas reductions. Most energy-efficiency upgrades pay for themselves through energy savings.

Keys to CO2 reductions
Some cities have been trailblazers in this trend, among other things by developing energy performance contracts which allow for financing through energy savings. Several cities have started green building programs, mandating energy efficiency in new and renovated buildings. Many cities have built demonstration districts, showing how housing in the future could save up to 80% in resource usage. And some cities have supported the development of passive houses, where energy consumption is cut to zero.
