This College Could Become the First 100% Renewable Campus in U.S.

As a growing number of U.S. cities make pledges towards 100 percent renewables, it's easy to forget that the entire state of Hawaii set this important benchmark three years ago when it mandated that all of its electricity must come from renewable sources no later than 2045.

To help the Aloha State meet this ambitious commitment, in 2015, the University of Hawaii (UH) and the Hawaiian Legislature set a collective goal for the university system to be "net-zero" by Jan. 1, 2035, which means the total amount of energy consumed is equal to the amount of renewable energy created.

Study Finds Timely Emissions Reductions Could Prevent 153 Million Air Pollution Deaths This Century

One of the roadblocks to swift action on climate change is the human brain's tendency to focus on threats and stimuli that are an obvious and noticeable part of their everyday lives, rather than an abstract and future problem, as Amit Dhir explained in The Decision Lab.

Now, a study published in Nature Climate Change Monday shows that acting quickly to curb greenhouse gas emissions would also reduce the air pollution that is already a major urban killer, thereby saving millions of lives within the next 40 years.
