It said that all seafood served to the athletes, officials, media and at the on-site restaurants will be wild-caught and responsibly farmed, while all wood and forestry products, including overlay structures, furniture, stationery and communication materials, will also be certified.
Earlier this month, Rio 2016 welcomed 25 civil society organisations to hear their contributions towards making the games even more sustainable.
Tania Braga, Rio 2016 head of sustainability, accessibility and legacy, said: “We had an extremely productive three days of work. I was impressed by the level of preparation, the quality of everything that was presented and the desire to contribute. It's an important step in our efforts to deepen dialogue with society and we can count on the help of all these organisations in the work that is ahead of us.
"We see a unique opportunity to make the most of the games' power as a catalyst, to meet the important needs of our society.”
