Introducing Cipher—Dispatches on Climate, Technology and Getting to Zero

Breakthrough Energy has launched Cipher, a new publication dedicated to accelerating the technological transformations required to get to net-zero greenhouse gas emissions by 2050 through trustworthy and objective journalism.

Sign up for Cipher

Cipher means zero, which we at Breakthrough find intriguing because our goal is simple, but hard. Going from the 51 billion tons of greenhouse gases we emit a year today to zero by 2050.

Cipher also means code. We aim to decode complex topics and make them clear to people at all levels working to solve the climate crisis — and anyone who wants to be an informed, concerned citizen.

We publish our newsletter most Wednesday mornings U.S. Eastern Time. We also have a regular video series where we interview newsmakers and innovators.

Our first edition featured an interview with U.S. Secretary of Energy Jennifer Granholm. Preview it here and subscribe to get Cipher in your inbox each week.
