Ten Things Individuals Can Do About Climate Change: Ranked Honestly

Wynes and Nicholas estimated that living car-free saves around 2.4 tonnes of CO2 equivalent per year ( Wynes and Nicholas, 2017). For many people in Britain, especially outside London and the larger cities, going fully car-free is impractical. The honest version of this action is a spectrum. Household transport still accounts for around 61 MtCO2e a year in the UK, and that figure has barely moved since 1996, unlike household heating which has fallen sharply (Defra).

If living without a car is not realistic, moving to one car per household rather than two, or to a smaller and more efficient vehicle, or to an electric one where circumstances allow, all move the needle. So does simply driving less: cycling short trips, walking the school run, using the train for longer journeys when time and geography allow. The point is that car ownership and use are among the largest single contributors to a UK household's carbon footprint, and small structural changes here compound.

A predominantly plant-based diet saves roughly 0.8 tonnes of CO2 equivalent per year compared to an average developed-country diet (Wynes and Nicholas, 2017). The gap between food types is larger than most people realise. Producing a kilogram of beef emits around 60 kilograms of CO2 equivalent, lamb around 24, cheese around 21, pork around 7, chicken around 6, and most legumes under one (Our World in Data, based on Poore and Nemecek).

You do not have to become vegan. Cutting back on beef and lamb specifically, treating red meat as an occasional feature rather than a daily one, and building meals around vegetables, grains and legumes all pull in the same direction. Around a quarter of global emissions come from the food system (Our World in Data). This is one of the few actions where partial progress genuinely helps: a family eating red meat once a week rather than four times has already made a substantial change. Read more about the environmental impact of meat diets. For anything that remains, credible climate finance can quietly do the rest, and this is one of the reasons we built a monthly individual offsetting subscription in the first place.

Roughly half of the UK's carbon footprint now sits in the things we import, and a large share of that is clothing, electronics, homeware, appliances and processed food. Every fast-fashion order, every replaced-because-it-broke appliance, every quickly-outgrown gadget carries emissions that were produced somewhere else on our behalf.

The single most effective change here is not choosing a "sustainable" version of the same purchase. It is buying less in the first place, and keeping what you own for longer. Not all purchases carry the same weight, and the honest order of impact is roughly this:

1. Cars. By a wide margin the highest-carbon single purchase most households make. Manufacturing a new car produces several tonnes of CO2 before it is even driven off the forecourt. Buying used, or keeping the one you have running longer, is almost always lower-carbon than buying new, including new electric.

2. Large appliances and electronics. Fridges, freezers, washing machines, dishwashers, televisions and desktop computers all carry significant embodied carbon. A large flat-screen TV can approach a tonne of CO2 across its life ( Statista, based on UN Trade and Development 2024). Repair rather than replace where possible, and when you do replace, buy for durability rather than newness.

3. Furniture. New furniture, particularly anything shipped from overseas, carries substantial hidden emissions. Second-hand is often better made, cheaper, and dramatically lower-carbon.

4. Personal electronics. Roughly 150 to 300 kilograms of CO2 to manufacture a typical laptop, and 50 to 90 for a smartphone, most of it locked in before you switch it on ( Ericsson, Embodied GHG emissions of ICT devices). Extending a phone's life from two years to four roughly halves its annual emissions. Repair screens. Replace batteries. Keep laptops for four or five years, not two.

5. Fast fashion. Worth a specific note, because the numbers are often overstated. The widely repeated claim that fashion produces "10% of global emissions" is contested: the UN Environment Programme's own official range is 2 to 8% ( UNEP, Sustainability and Circularity in the Textile Value Chain). Even at the lower end, textiles are one of the largest sources of imported emissions into the UK, and fast fashion specifically produces roughly eleven times the per-wear carbon footprint of longer-lasting clothing ( Guan et al., 2024, Science of the Total Environment). Fewer garments, kept longer, washed cooler, and repaired when they wear will do more than any "sustainable" label alone.

The reliable pattern is that heavy items with long manufacturing chains sit at the top, and small frequent purchases lower down. Buying less in the first two or three categories will do more than perfect discipline in the last. Read more about UK consumption habits and its impact on deforestation.

Where you keep your savings, pension and investments has a larger climate footprint than most people realise. A typical UK workplace pension, invested by default in broad global funds, will hold shares in oil and gas majors, banks that finance them, and heavy industries that depend on them. Moving that money into a fund that either excludes fossil fuels or actively supports the transition can, for many people, be one of the biggest single climate decisions they make in a given year.

Make My Money Matter, a UK campaign founded by filmmaker Richard Curtis, has argued that switching pension providers can be twenty-one times more effective than the combined impact of going vegan, giving up flying and switching energy provider (Make My Money Matter, 21x campaign). That specific figure deserves care: it depends on the size of the pension pot and the funds compared, and campaigners have an interest in dramatising it. Even at a fraction of that estimate, though, it remains one of the highest-leverage individual actions available.

Ask your pension provider which fund you are in. Ask whether a low-carbon or fossil-free option exists. It usually does, and moving is often a matter of ticking a box.

This one belongs on the list because individual behaviour change, at the scale of one household, is dwarfed by policy. A single well-designed national policy on home insulation, or on aviation fuel, or on grid decarbonisation, saves more emissions in a year than most of us could save in a lifetime.

Voting for candidates who take climate seriously, writing to your MP, joining a local campaign, supporting well-run environmental organisations, backing local planning applications for renewables and rejecting new fossil fuel infrastructure: these are all quiet, ordinary acts. They do not photograph well. They shape the country in which the other nine actions on this list become easier or harder to take. The Climate Change Committee's advice to government is public and worth reading (Climate Change Committee) if you want to know what an evidence-led national policy actually looks like.

The reductions above address emissions still to come. They do not address the carbon already in the atmosphere from more than a century of industrial activity. Cumulative CO2 does not simply expire when the West stops burning coal.

This is why credible climate finance sits alongside reduction, not after it. Funding verified emissions reductions and carbon removals now, through certified projects on recognised registries such as Verra, Gold Standard or Plan Vivo, is a way for individuals and businesses to take responsibility for what cannot yet be reduced and, in the case of removals, to begin drawing down historic emissions. CNB's own portfolio of verified offset projects uses these three standards, and each project is documented with the registry evidence you would expect. Read our article about offsetting compared with reducing emissions.

CNB's view is that this is not either-or climate action. Reduction changes the emissions still to come. High-integrity removals address the carbon already in the atmosphere. Both are needed, and both need scrutiny. Scrutiny is not a reason to abandon offsetting. It is a reason to demand better offsetting: methodologies that are public, projects that appear on active registries with retirement records, and providers who can show their working. That is the standard our certification process for British businesses is built around, and it is the same standard any individual buying credits should apply. We have written more about the specific standards we use for readers who want to look under the bonnet.

It is not a scoreboard, and it is not a way to tell anyone they are failing. Most people reading this will already be doing several of these things, imperfectly, and that is exactly how it should be. Climate action at the individual level is a lifetime of small structural adjustments, occasionally punctuated by a larger decision.

It is also not a way to let governments or industry off the hook. If we could redraw the UK's carbon footprint tomorrow so that half of it was no longer hidden in imports, the pressure on domestic manufacturing, agriculture, aviation and finance would look very different. Consumer choices matter partly because they are honest about where the emissions live, in a way that our official targets are not yet designed to be.

And it is not, whatever the internet occasionally suggests, an argument for despair. British households have already cut their heating emissions by nearly 40% since 1996. Renewable electricity now regularly supplies more than half the grid on windy days. Younger generations are eating less meat, flying less by choice, and moving their pensions in numbers that would have been unimaginable a decade ago. None of this is enough on its own. All of it is happening, and it is happening because ordinary people started doing ordinary things differently.

The habit of blaming distant factories is understandable. It puts the problem somewhere else, in a country most of us will never visit, in a system too large to feel personal. But the emissions produced in those factories are, by any honest accounting, also ours: bought, shipped, worn, used and eventually discarded here. We do not need to feel guilty about that. We do need to notice it.

Once you notice, the ten actions above stop looking like a lifestyle checklist and start looking like something more useful: a series of ordinary decisions, most of which improve life in other ways too. Fewer flights, more time at home. Less clutter, more considered purchases. Better-insulated homes, lower bills. A pension that quietly finances the transition rather than the delay of it.

The change can start whenever we decide to make it, driven by different consumption rather than different politics abroad. That is not a comfortable thought, but it is a hopeful one.

Individual climate action in Britain has been quietly reframed over the last two decades. We used to be told that our personal choices barely mattered. Then we were told they were everything. Neither is quite right.

What is true is that individual consumption, in aggregate, is now the largest hidden component of Britain's real carbon footprint, and it is the component our official targets have been slowest to acknowledge. Every serious action on the list above pulls, in some way, on that hidden half. Doing them will not solve climate change on its own. Not doing them makes solving it much harder.

CNB helps British businesses navigate the same principle at scale: reduce genuine emissions where possible, fund verified climate action for what remains, and be honest about the evidence in both directions. The same principle applies to households. Ordinary decisions, made carefully, add up to something that looks a lot like progress.
