Harvard researchers examined the nation’s registry, where oil and gas production companies disclose the chemicals they use in hydraulic fracturing, and found that they do it less than in the past.

The Paris agreement to fight climate change greatly expands the international commitment to the cause, Harvard Professor Stavins says.

The need for continuous rigorous and relevant climate science will be more important than ever. With that framing, a group of scholars on Wednesday shared their ideas for improving the process by which the Intergovernmental Panel on Climate Change (IPCC) carries out its research agenda, at a side panel at the U.N. Climate Change Conference in Paris.

The private sector — from large corporations to small businesses — will undoubtedly be impacted by whatever international agreement emerges from the U.N. Climate Change Conference taking place in Paris, but opinions vary as to how burdensome and costly those impacts will be.

Harvard scientists are helping launch a new initiative to foster collaboration among scientists working at the intersection of the environment and health.

A side-event panel titled “Dialogue on the Comparison of Climate Change Policies” on Friday at the Conference of the Parties (COP21) featured Robert Stavins, faculty director of the Harvard Project and Harvard Project Manager Robert Stowe.

Using a simple game in which candy is distributed between two players, researchers found that children in various countries were quick to reject unfair deals, but in three countries they were also willing to reject deals unfair to others.

Panelists at the Kennedy School on Monday expressed optimism about the U.N. climate conference set to begin in Paris on Nov. 30, calling U.S. participation on the heels of domestic climate-related moves a “game-changer.”
