Klima vs Commons: Which Carbon Tracking App Is Better

Key Takeaways

‍

• Klima estimates your carbon footprint from a short lifestyle quiz. Commons calculates it from your actual purchases.
• Both fund verified climate projects: Klima through a monthly subscription and Commons through a curated portfolio.
• Commons also helps you cut emissions with No-Buy Streaks, brand sustainability ratings, and points for low-impact choices.

‍

Klima and Commons both calculate your carbon footprint and let you fund climate projects, but they measure your impact in very different ways. Here is how the two compare, so that you can decide which one fits where you are right now on your sustainability journey.

Klima vs Commons at a Glance

‍

‍

Klima: A Simple Place to Start

‍

Klima keeps things light. Its calculator focuses on the few emission factors that move your footprint most, that you can answer off the top of your head, and that you can actually change. Pick a subscription, fund science-based projects that capture or prevent the same emissions elsewhere, and watch a real-time tracker show the impact on the ground.

‍

That simplicity is the point. If you are just starting and you want one clear step, Klima gets you there quickly.

‍

Commons: Tracks Your Spending To Calculate Your Footprint

‍

Instead of answering lifestyle questions, you connect your cards to Commons to see your climate impact. The app reads your purchases and estimates emissions for each transaction and your overall carbon footprint. With a single toggle, you can view the emissions associated with a coffee, a flight, or a thrifted jacket. Similar to Klima, Commons also offers a curated portfolio of verified climate solutions to offset your footprint. But it doesn’t stop there. It also helps you reduce your carbon footprint through:

‍

• No-Buy Streaks: Pick one thing to skip for the month, like fast fashion or a Prime subscription, and watch your streak (and your savings) grow.
• Brand sustainability ratings and reviews: Search hundreds of expert-rated brands before you shop, so you can skip the greenwashing and find quality that lasts. Then, see what our sustainably-minded community had to say about the brands.
• Points and rewards: Earn points for sustainable choices like thrifting or taking public transit, then redeem them for gift cards or trusted climate solutions.
