Dispatches on Climate, Technology and Getting to Zero.

About Cipher

Cipher is a publication by Breakthrough Energy.

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.

Meet Amy Harder

Amy Harder, a longtime energy and climate change journalist, is the executive editor of Cipher. Before joining Breakthrough in early 2021, Amy has covered these topics for Axios, The Wall Street Journal and more.

Breakthrough Energy

Breakthrough Energy is a network of investment vehicles, philanthropic programs, policy advocacy and other activities committed to scaling the technologies we need to reach net-zero emissions by 2050. Its founder is Bill Gates, Microsoft co-founder and co-chair of the Bill and Melinda Gates Foundation.

Our Mission

The mission of Cipher is to help accelerate the technological transformations required to get to net-zero greenhouse gas emissions by 2050 through trustworthy and objective journalism. 

We will facilitate the critical conversations that help us understand the challenges and opportunities of these needed transformations.  

Cipher editorial leadership has final say over our journalism. We include disclaimers as needed when we cover topics, people and/or companies that are in or connected to the Breakthrough Energy network.
