Everyday choices, lasting impact

HOW YOU
MOVE MATTERS.

Transport is responsible for around 27% of UK carbon emissions. How you get from A to B every day adds up faster than any holiday flight.

GETTING FROM A TO B

Grams of CO₂ emitted per kilometre, per passenger. Source: UK Government DEFRA / Our World in Data 2024. Your daily commute decision is one of the highest-impact choices you make all year.

Short-haul flight

255

gCO₂ per km

The single highest-impact way to travel. A return London–Edinburgh flight emits more CO₂ than 3 months of average driving.

Petrol / diesel car

170

gCO₂ per km

Solo driving is expensive and carbon-heavy. Sharing with one passenger halves this figure immediately.

Electric car (UK grid)

47

gCO₂ per km

72% less than petrol on the current UK grid, and improving every year as renewables grow. Significant — but not zero.

Bus / coach

29

gCO₂ per km

Often overlooked. A full bus produces a fraction of the same number of cars. Electric buses are even better.

Best

Cycling / walking

~0

gCO₂ per km

Zero direct emissions. The food calories burned cycling add a negligible ~16g CO₂/km on a typical diet.

RETHINK YOUR COMMUTE

Switch one commute a week to cycling

If every UK commuter cycled just once a week instead of driving, it would cut transport emissions by around 7%. For the average 10km commute, cycling saves roughly 1.7kg CO₂ each way.

↓ ~170kg CO₂/yr on a 5-day week

Take the train for longer journeys

For commutes over 20km, rail is 6× less carbon-intensive than driving alone. Season ticket prices have come down relative to fuel costs — it's often cheaper too, especially with a railcard.

↓ Up to 85% less CO₂ vs solo driving

Work from home when you can

One day working from home per week can cut your annual commuting emissions by 20%. The key is making sure your home energy is renewable — otherwise the savings are smaller than they appear.

↓ ~20% transport emissions per WFH day

If you drive — share the journey

Carpooling with one other person immediately halves your per-person emissions. Apps like Liftshare and BlaBlaCar make it easy to find commute matches. Splitting fuel costs helps too.

↓ 50% emissions with one passenger

Consider an e-bike for medium distances

E-bikes extend the practical cycling range to 20–30km, making them a genuine car replacement for many commuters. The UK government's Cycle to Work scheme offers tax savings of up to 47% on purchase.

↓ Near-zero emissions, 5–40km range

Offset unavoidable journeys via Climeworks

Some commutes simply can't be avoided. For those, Climeworks' direct air capture removes actual CO₂ permanently — not tree-planting promises. From £7/month for 50kg of removal.

Electric vs petrol

ELECTRIC VS PETROL

EVs are significantly better for climate — but the honest picture is more nuanced than the headlines suggest. Here's the data.

Petrol carHigh impact
CO₂ per km (tailpipe)~170g
Annual fuel cost (10,000 miles)~£1,800
Road tax£190–£600/yr
Servicing (avg)~£500/yr
Manufacturing CO₂~6t CO₂
Lifetime CO₂ (10 yrs avg)~41t CO₂
Electric carLower impact
CO₂ per km (UK grid 2024)~47g
Annual energy cost (10,000 miles)~£600
Road tax£0 (until 2025)
Servicing (avg)~£200/yr
Manufacturing CO₂~10–14t CO₂
Lifetime CO₂ (10 yrs avg)~18t CO₂

THE HONEST PICTURE

EVs are better — significantly — but manufacturing a new EV still produces around 10–14 tonnes of CO₂ before it leaves the factory, largely due to battery production. This means the greenest car is often the one you already have, run for as long as possible.

If you are switching, the best time to buy an EV is now — the UK grid is getting greener every year (35% renewable in 2024, up from 7% in 2010), so the lifetime emissions of an EV bought today will be lower than one bought in 5 years.

Second-hand EVs are the sweet spot: the manufacturing carbon is already spent, and you benefit from the lower running emissions. The Nissan Leaf, Renault Zoe and earlier Teslas are strong used options.

Planes vs trains

FLIGHT VS TRAIN

For most European routes, the train is not only dramatically lower-carbon — it's often comparable door-to-door once you factor in airports.
