How to reduce your carbon footprint.
The most effective climate action is the emission you never make. This is the practical playbook: measure your footprint, cut the biggest sources first, lock in the structural changes that compound — then offset only what you genuinely can’t eliminate yet.
Measure, reduce, then offset.
A simple order of operations that puts cutting emissions first and offsetting where it belongs — last, for the remainder.
You can’t cut what you don’t count. Estimate your annual tonnes of CO₂e — by country — across travel, home energy, diet and spending.
A handful of categories dominate most footprints. Target those before the small stuff — one long-haul flight can outweigh a year of careful recycling.
Switch to a renewable energy tariff, electrify heating and transport over time, and shift diet and spending. These compound year after year.
Some emissions are unavoidable today. Offset the remainder with verified, registry-retired credits — alongside cutting, never instead of it.
Where your emissions actually come from.
For most people the largest sources are flights (a single long-haul return can outweigh a year of driving), car travel, home energy (heating and electricity), diet (especially red meat and dairy), and the goods and services you buy. Focusing on these few beats sweating the small stuff. Calculate your footprint to see your own breakdown.
What to actually do.
High-impact changes by category — start with travel and home energy, where the biggest savings usually sit.
- ›Fly less and direct; one fewer long-haul return can save 1–3 tonnes
- ›Choose train over plane and car where possible
- ›Switch to an EV or hybrid; combine and reduce car trips
- ›Work from home or carpool a day or two a week
- ›Move to a certified renewable electricity tariff
- ›Replace gas heating with a heat pump over time
- ›Insulate, draught-proof and turn the thermostat down 1°C
- ›Switch to LED lighting and efficient appliances
- ›Eat less red meat and dairy; even a few plant-based days/week helps
- ›Cut food waste — plan, store and use leftovers
- ›Buy seasonal and local where practical
- ›Buy less, buy better, repair and reuse
- ›Choose second-hand and durable goods
- ›Recycle properly and avoid single-use plastic
- ›Move savings and pensions to greener funds
- ›Use your voice — at work, with providers, as a voter
- ›Choose businesses with credible climate commitments
Scope 1, 2 and 3.
Businesses organise emissions into Scope 1 (direct fuel and fleet), Scope 2 (purchased electricity) and Scope 3 (supply chain and travel — usually the largest). Measure all three, then prioritise the biggest: switch to renewable power, improve efficiency, decarbonise the fleet, and engage suppliers. Offset residual emissions with durable removals as part of a science-based net-zero plan. See business offsetting →
Then offset what you can’t cut.
Even the greenest life has unavoidable emissions today. Offsetting them with verified, registry-retired credits funds real reductions elsewhere while you keep cutting your own — the honest order is reduce first, offset the remainder.
Common questions.
How can I reduce my carbon footprint?
Start by measuring your annual footprint, then cut the biggest sources first — usually flights, driving, home heating, diet and consumption. Switch to renewable energy, fly and drive less, eat less red meat, waste less, and electrify over time. Finally, offset the emissions you can’t yet eliminate with verified, registry-retired carbon credits.
What is the biggest contributor to a personal carbon footprint?
For most people in higher-income countries it’s flights, car travel and home heating, followed by diet and the goods they buy. A single long-haul return flight can emit more CO₂ than months of everyday activity, so reducing air travel is often the single highest-impact change.
What is the average carbon footprint per person?
The global average is roughly 4.7 tonnes of CO₂e per person per year, ranging from under 2 tonnes in many lower-income countries to 14+ tonnes in the US and Australia. A Paris-aligned target is around 2.3 tonnes per person.
Is it better to reduce or offset emissions?
Reduce first — cutting emissions is permanent and removes the source. Offsetting is for the emissions you can’t yet eliminate; it funds reductions elsewhere but shouldn’t replace cutting your own. The credible approach is reduce, then offset the remainder with high-quality credits.
How do I offset the carbon I can’t cut?
Calculate the tonnes you can’t eliminate, then buy verified carbon credits that we retire on a public registry in your name, with a certificate you can verify. You can offset a one-off amount or set up a recurring offset for your ongoing footprint.
How can a business reduce its carbon footprint?
Measure across Scope 1 (direct), Scope 2 (purchased energy) and Scope 3 (supply chain and travel), then prioritise the largest sources: switch to renewable power, improve efficiency, decarbonise the fleet and engage suppliers. Offset residual emissions with durable removals as part of a science-based net-zero plan.
