Japan has put a spotlight on sustainability at the 2020 Olympic Games, with athletes standing on podiums made of recycled plastics to receive medals crafted from recycled small electronics before sleeping on beds made of cardboard.

Electric cars ferry competitors and media between venues, many of which are temporary constructions made of recycled wood that will be dismantled after the Games, preventing the white elephant stadiums left behind in other host cities.

The Tokyo organising committee has hung its hat on providing a "beyond carbon neutrality" event, a goal it will meet with the help of donated carbon offset credits from businesses in Tokyo and Saitama prefectures, the two Games locations, along with the lack of spectators.
