Out of Office: I Offset My AI With AI for 96 Cents, Over Breakfast

August means vacation for my family, and, though I’m not fully out of the office — b/c *cough* …living the start-up dream, in the age of 24-hour AI-powered product development… — some regular business is backgrounded for a bit, including detailed invoice review.

So, while planning sightseeing over breakfast a few days ago, I was pleasantly surprised to see a ‘CarbonGuru.io Automatic renewal notice’ in my inbox, for an upcoming offset order covering the climate impact of Claude Code, ChatGPT, DreamHost, and related services — 36 kg of CO₂e in total, for a cost of $0.96.

To be honest, I’d forgotten about setting up recurring offsets for these. One of the early tests of CarbonGuru’s automated offsetting via agent was a session at the beginning of the summer using Claude connected to the CarbonGuru MCP server to estimate the carbon footprint of some of the AI, application hosting, and other digital services that power the platform itself (screen recording here). After confirming the MCP tools and end-to-end automation functionality worked, I’d posted the recording, and gone on to building other features.

Thirty days later, between sips of coffee, I was relieved to realize that I’d (accurately) assumed I would forget to use my own product — yes, I know… — during our upcoming vacation, and taken the agent’s recommendation to make the offsetting for several of CarbonGuru’s regularly billed AI tools a recurring subscription, instead of a one-time purchase. Effortless, affordable, automated climate impact management is literally on the CarbonGuru homepage, so as a builder, it’s a tremendous relief gratifying when your product actually works genuinely delivers as claimed.

Large enterprises consider this kind of exercise vanilla carbon accounting, typically something that dedicated in-house sustainability and finance teams take on; often using a combination of specialized tools and licensed data sets for the detailed LCA calculations, then integrating with an established ERP suite and a compliance-focused SaaS platform for the scaled carbon accounting and reporting.

Mid-sized firms that are conscientious about managing environmental impact might take this on as one instance of a quarterly or semi-annual exercise in ‘Understanding our impact’, passing the new question of carbon footprints generated by the AI services they’re experimenting with to a sustainability consulting provider, which consolidates data across silos to estimate operational footprints, and composes bespoke offsetting programs for clients.

For most technology product and service startups — and for small businesses in general — the ability to accurately estimate carbon footprints and climate impact for a rotating basket of AI and software tools, and then automatically set up recurring offsetting on a predictable schedule for the ones that persist in the stack, is wholly new. CarbonGuru combines LCA, carbon accounting, and offset sourcing and acquisition with agent-based automation to integrate all of these directly into existing admin workflows without additional friction to close the gap for you — even when on vacation.

In my case, from the customer perspective, it meant I could go back to a proper vacation task: looking for ways to keep my kids off their screens for the rest of the day, while seeing a foreign city.

The footprints behind the 36 kg

The combined footprint for these services is 36 kg CO₂e. To see detailed analysis on all the line items — the ChatGPT Plus subscription has a footprint of 1.42 kg CO₂e, roughly comparable to a bag of potato chips — here are some of the carbon footprints mentioned:

• Claude Code Max — 16.91 kg CO₂e · similar footprint to 1× sleeping bag
• ChatGPT Plus — 1.42 kg CO₂e · similar footprint to 1× bag of potato chips
• DreamHost — 12.68 kg CO₂e · similar footprint to 1× wireless headphones
• Figma — 1.51 kg CO₂e · similar footprint to 1× USB-C cable (6 ft)

The individual carbon credits and retirements include a variety of locations, methods, and registries around the globe, incidentally reflecting the reality that my carbon is also your carbon, and anyone’s offset benefits everyone, since we all share the same atmosphere.

Here are three of the individual carbon offsets purchased in this most recent round (every order is matched automatically to offsets each month):
