How to reduce your carbon footprint
The most effective path is simple: measure where your emissions come from, then go after the biggest levers first. Here is how — with the tools to do it.
Start by measuring
You cannot shrink what you have not measured. Most people are surprised by where their emissions actually come from — it is rarely the things they feel guiltiest about. Calculate your carbon footprint to get a clear breakdown across home energy, travel, food and the rest, so you know which lever is worth pulling first.
Then aim for the heavy categories. For most households a handful of changes — how you heat your home, how you get around, and what you eat — account for the majority of the footprint. The guides below go deep on each.
Where to start
Four steps, in order: measure, commit, contribute, and do it together.
Calculate your footprint
Get your personal breakdown in a few minutes and find your biggest levers.
Commit to a change
Turn intent into a concrete pledge you will actually keep.
Contribute to projects
Fund verified climate action for the emissions you cannot yet cut.
Join the community
Change sticks better together — see what others are doing.

The Main Greenhouse Gases You Can Actually Reduce
Carbon dioxide gets the headlines, but it is one of several greenhouse gases warming the planet — and some of the others are easier for you to cut than you might think. Here are the main ones, and where your choices actually move the needle.
Switch to Renewable Energy to Cut Household Emissions
Home energy is one of the largest, most controllable parts of a personal carbon footprint. Switching to renewable electricity — and electrifying what you can — is among the highest-impact moves available to most households.
Practical Ways to Reduce Your Carbon Footprint at Home
Your home is where many small changes add up to a real reduction. Here is a practical, no-guilt checklist — and how to know which changes matter most for you.
Plant-Based Diet and Carbon Footprint: A Real Comparison
Going plant-based is one of the most talked-about ways to cut a personal footprint — but how big is the effect, really? Here is an honest comparison of diets, food miles, and what matters most.
Reduce Methane Emissions From Your Food Choices
Methane is a greenhouse gas roughly 80 times more potent than CO₂ over 20 years — and a large share of it comes from how we produce food. The good news: food is one area where everyday choices add up fast.
Low-Carbon Travel Tips That Make a Difference
Transport is a top-three slice of most personal footprints, and travel choices are some of the most visible. Here are the changes that genuinely move the needle — and the ones that are mostly noise.
Are Biofuels Better for Your Carbon Footprint?
Biofuels — ethanol, biodiesel, sustainable aviation fuel — are sold as a greener alternative to fossil fuels. Sometimes they are; sometimes they are not. The answer depends on what they are made from and what land they displace.
Brown Coal: Why It Matters in Your Energy Mix
Brown coal, or lignite, is the most carbon-intensive way to make electricity. If it is in your grid mix, it quietly inflates the footprint of everything you plug in. Here is why it matters and what to do about it.
Know your number, then shrink it
The fastest way to start is to measure. Get your footprint, pick one big lever, and go.
