The B. League’s Nagoya Diamond Dolphins have become the first top-tier professional Japanese sports club to sign on to a climate change initiative spearheaded by the United Nations, joining a growing movement of sports teams tackling social issues in their community and beyond.

The U.N. platform, called the Sports for Climate Action Framework, is part of the United Nations Framework Convention on Climate Change (UNFCCC) initiatives.

The initiative calls on sports teams and organizations from around the world to take leadership in the fight against climate change and undertake systematic efforts to promote greater environmental responsibility as well as reduce climate impact.
