Seoul City has decided to reduce greenhouse gas emissions from buildings by 26-point-nine percent by 2020.
Under the first "green building" plan announced on Wednesday, the city government will revise related laws in phases mandating construction of “zero-energy buildings” between March 1 this year and 2023.
A zero energy building is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site such as solar heat.
Buildings account for 64 percent of the city’s total greenhouse gas emissions. The city’s green building plan was established first and will be re-established every five years.
The move is a follow-up measure to the agreement adopted at the Conference of the Parties, known as COP21, of the UN Framework Convention on Climate Change in Paris in December last year.
