TOKYO - Japanese Olympians stepping up to the podium in Paris will have more than a medal to be proud of this summer: the carbon footprint of their eco-friendly team kits.

Unveiling Team Japan's official wear on Wednesday, Asics said the jackets, trousers and other items athletes will wear on the podium and at press conferences would have the amount of carbon dioxide emitted during production stamped on them, in a nod to the green goals put forth by the host city.
