The Carbon Cost of Everyday Choices: A Guide to Mindful Living

Every purchase, every meal, every trip has a carbon cost—but some costs are far higher than others. Understanding the climate impact of common choices helps you make trade-offs consciously rather than blindly. This isn't about guilt; it's about informed decision-making that aligns your values with your actions.

Who is the test for?

The PS Lifestyle test is for anyone who’s concerned about global warming, and wants to understand what kind of impact their lifestyle has on their carbon footprint, and the environment.

What you get

By answering a few questions, we provide a detailed look at your personal carbon footprint,. You also get tailored lifestyle tips and an action plan. You also help steer society towards a positive and sustainable future.

Making Visible What's Usually Invisible

The hardest part about sustainable living is that consequences are invisible. When you drive to the store, you don't see the CO2 entering the atmosphere. When you buy new clothes, you don't witness the energy and water consumed in production. When you order beef, the massive land use and emissions are hidden behind restaurant walls. Our modern economy deliberately obscures these connections—what you see is the product, not the process. That makes unsustainable choices easy and sustainable ones hard, because only immediate costs (price, time, convenience) are visible.


Let's make some costs visible. A round-trip transatlantic flight: roughly 2-3 tons of CO2e—as much as the rest of your year combined. Owning a gas car driven average distance: 2-4 tons annually. Heating a poorly insulated home: 2-3 tons. Eating beef regularly: easily 1 ton or more. These aren't minor factors—they're the bulk of most people's footprints. Compare to things we often worry about more: plastic bags, paper versus digital, long showers. These matter, sure, but they're rounding errors compared to the big four: transportation, housing, food, and stuff.


Mindful living means conscious trade-offs. Maybe you fly occasionally for important family visits but commit to never flying for frivolous weekend trips. Maybe you eat meat but choose chicken over beef and never waste food. Maybe you drive but keep the car longer, maintain it well, and combine trips efficiently. Maybe you buy new clothes but invest in quality pieces that last years instead of fast fashion worn twice. These trade-offs acknowledge reality: we can't be perfect, but we can be strategic. Research on behavioral priorities reveals which trade-offs people find sustainable versus which lead to guilt and burnout.


Take the Lifestyle Test to see your specific carbon costs across categories. Once you know where your emissions concentrate, you can make informed trade-offs rather than optimizing randomly. Some people have strong preferences (love flying, don't care about meat) while others are opposite (vegetarian, never fly). That's fine—what matters is dramatically reducing your total footprint, not following some one-size-fits-all playbook. Mindful living respects your values and circumstances while ensuring your choices align with climate realities. That's empowerment, not restriction.
