Green Building Symposium Decarbonizing Buildings and HousingsSynergy of Energy Efficiency and Renewable Energy in the Building Sector

5 October 2018

in Japanese

In line with the Paris Agreement, decarbonization in the building sector has to accelerate both in terms of speed and depth. Japan’s Intended Nationally Determined Contribution (INDC) submitted to the UNFCCC sets a greenhouse gas (GHG) emissions reduction target of 40% by FY2030 compared with FY2013 in the building sector (commercial and residential).

Achieving such goal in reducing GHG emissions requires not only to seriously boost energy efficiency in buildings, but also to deploy and utilize renewable energy on a large scale, and commit to decarbonize the power sector. In fact, energy efficiency improvements and renewable energy deployment in the building sector, when pursued together, can exert significant effects on emissions reduction, but such synergies are not widely recognized yet.

Amory B. Lovins, author of the influential book “Reinventing Fire,” in which he affirmed that decarbonization can create a prosperous economy, is invited to this symposium among other experts.  By getting insight on their views on the future outlook of buildings and energy uses in the era of global decarbonization, we hope this symposium can provide a platform to discuss and understand what the challenges are and what needs to be done today.
