A personalized daily climate newsletter, written just for you

Climate is not one topic - it is fifty. Grid-scale batteries, carbon markets, EU policy, adaptation finance, atmospheric science, corporate disclosure rules: each is its own fast-moving beat, and general climate coverage either drowns you in doom or skips the technical substance you actually want. Meanwhile the field genuinely changes month to month, as costs fall, policies pass, and research lands.

Briefed lets you pick your fifty-first version. Describe the intersection you care about - say, the economics of solar and storage plus European energy policy, or climate tech startups and carbon removal, or adaptation and water - and Claude writes each issue for you personally, researched from public web sources at send time. It is not a mass newsletter with segments; it is one newsletter, written for one reader, and no two subscribers get the same one.

Most climate readers choose weekly or every-two-days delivery, but daily is there if you work in the field. Steering is conversational: reply to an issue with 'more on grid infrastructure, less on COP diplomacy' and the next issue follows. Briefed is completely free - no paid tier, no ads, no credit card - with a 30-second signup, double opt-in, and one-click unsubscribe.
