詳細な研究レポート
- The need for office space could be reduced due to dematerializations including fewer bookshelves, thinner screens, less paper, no fixed phones, fewer printers and so on, but it is assumed that this potential has to a large extent already been realized.
- However, some potential still remains in terms of flexi-work spaces, open offices, etc., especially in the global perspective.

- We assess the greenhouse gas emissions of this transition, considering factors including information and communication technology, commuting, noncommute travel, and office and residential energy use.
- We find that, in the United States, switching from working onsite to working from home can reduce up to 58% of work's carbon footprint, and the impacts of IT usage are negligible, while office energy use and noncommute travel impacts are important.
