2025 Decarbonization Presentation

Today I published my annual decarbonization presentation. You can view it here: https://www.nathanielbullard.com/presentations Blog_decktitlejan2920252025 marks the third year I've completed this labor of love. There's so much going on, so much noise and so much signal, and so many important potential inflection points. The story is much more complex than it was even five years ago, and it's remarkably different as well. 

When Bruce and I founded Halcyon, one of our BHAGs (big hairy audacious goal) was that eventually, Halcyon could power all the data and research contained within this presentation. At exactly 200 slides, we're not quite there yet — but we are on our way. 

In addition to my annual presentation and my contributions to Machine Readable, I also publish a weekly roundup of the interesting things I discovered via Halcyon Alerts every Friday morning. Sign up for Halcyon Alerts to get exclusive access to that note as well.

I'm grateful to my colleagues, customers, and all of you readers for your feedback and support. Thank you, and as always, if you have any thoughts or questions, drop me a line at sayhi@halcyon.eco
