This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

The peer-reviewed update of ENRP's ongoing research on renewable hydrogen is featured in the June volume of Geopolitics, History, and International Relations, an academic journal of which Dr. Nicola de Blasio is now also an editor.

Harvard University has created a Presidential Committee on Sustainability (PCS) to advise President Larry Bacow and the University's leadership on sustainability vision, goals, strategy, and partnerships. The Harvard Gazette spoke with committee chairs Rebecca Henderson, the John and Natty McArthur University Professor; John Holdren, the Teresa and John Heinz Professor of Environmental Policy at Harvard Kennedy School; and Katie Lapp, executive vice president, about why it is so important to act now; the role of the PCS in developing collaborative and innovative projects; and how the campus community can get involved.

In this edition of "The Interview," Fair Observer talks to Professor John Holdren, former science adviser to President Barack Obama and director of the White House Office of Science and Technology Policy from 2009 to 2017 about the impacts of global warming on the United States and the government's strategies to combat climate change.
