To Tree or Not to Tree – How Many Is Enough for Carbon Offsetting My Life?

(Or: Can I Just Plant a Hedge and Call It Even?)

Let’s be honest. We've all had that moment where we think:

“If I just plant a few trees… I can keep eating cheese, flying to Valencia, and running my tumble dryer with a clear conscience, right?”

Well, not quite. But you’re not alone in wondering:
How many trees does it actually take to offset my life?

Spoiler: it’s more than one.

🌍 What Even Is Carbon Offsetting?

Carbon offsetting is the act of compensating for your own carbon emissions by investing in projects that reduce CO₂ elsewhere — such as:

  • Planting trees

  • Restoring peat bogs

  • Funding renewable energy projects

  • Paying for someone else not to burn a forest down

Planting trees is the classic option. It’s tangible, green, and doesn’t require a PhD in climate economics to understand.

But…

🌳 How Much CO₂ Does a Tree Actually Offset?

Let’s crunch some numbers (sustainably, of course).

  • A young tree absorbs about 5–10 kg of CO₂ per year

  • A mature tree can absorb up to 20–25 kg per year

  • Over its full life (say 40 years), one tree might absorb 1 tonne of CO₂
    (assuming it lives that long, isn’t chopped down, and doesn’t die in a drought)

📈 The UK Average Carbon Footprint

According to the UK Government:

  • The average UK person emits about 10–12 tonnes of CO₂ per year

  • That includes home energy, transport, food, shopping, and holidays

So…

You’d need to plant 10–12 trees every single year
And wait 40 years
And protect them like your favourite pet

Or to offset your entire life until age 80?
Somewhere around 800–1,000 trees.

🪓 The Reality Check

Planting trees is great. But it’s not a get-out-of-jail-free card.

  • Trees take decades to absorb the carbon you're emitting right now

  • A single return flight to New York? 2 tonnes CO₂ — that’s 2 trees per year for 40 years

  • Buying offsets from dodgy websites? Often greenwashing

🗨️ “Offsetting without reducing is like eating cake on a treadmill and wondering why you’re not getting fitter.”

🌿 So, Should I Plant Trees? Yes — But Also…

✅ Reduce what you can

  • Cut food waste

  • Use public transport

  • Switch to green energy

  • Don’t leave the fridge open long enough to name the condiments

✅ Offset what you can’t

  • Flights, cars, heating

  • Choose certified, verifiable offsetting schemes (e.g. Gold Standard, Woodland Carbon Code)

✅ Plant trees anyway

  • In your garden

  • In local community spaces

  • Or support reforestation charities

  • Bonus: they make you feel better, clean the air, and attract squirrels

🌲 How Many Trees Have We Planted?

  • We’ve added hedgerows, apple trees, and shade trees around our house

  • We support projects that restore UK woodlands

  • We also use solar panels, battery storage, and an electric boat — because offsetting only works if you’re also reducing

🌳 Final Thought: Offset Smart, Not Just Hard

Yes, trees are wonderful. They’re nature’s slow-motion carbon vacuum cleaners. But we can’t just keep emitting and hope the oaks will sort it out later.

Shower Power – Saving Water Without Turning Into a Smelly Hippie

  Shower Power – Saving Water Without Turning Into a Smelly Hippie ( Or: How Solar Hot Water Quietly Became the Unsung Hero of Sustainability ) Let’s talk about something personal. Steamy. Daily. Environmentally impactful. That’s right — your shower. Now, I’m all for reducing water use, but not if it means becoming one with your own scent . You’ll be glad to hear that saving water and energy doesn't require cold showers, fewer showers, or turning into a low-pressure dribble monk. Especially if — like us — you’ve tapped into the magic of the forgotten solar : solar hot water . 🌞 Why Solar Hot Water Deserves More Hype Everyone's talking about solar PV panels, battery storage, and smart meters. But solar thermal panels ? Hardly a whisper. Which is a shame, because: They’re cheaper to install They have fewer moving parts The return on investment (ROI) is often higher And they provide hot water for free from around March to October 🗨️ “Yes, our kettle i...

Greenwashing for Beginners: How to Spot an Eco-Con

  Greenwashing for Beginners: How to Spot an Eco-Con ( Or: Just Because It’s Green Doesn’t Mean It’s Clean ) Ever bought a product that had leaves on the label, a name like “Eco-Fresh Ultra Clean”, and a picture of the Earth… only to discover it’s wrapped in five layers of plastic and was shipped from the other side of the world? Congratulations. You’ve been greenwashed. Let’s dive into what greenwashing is, how to spot it, and how to avoid falling for it — even when it’s wearing a hemp T-shirt and whispering about carbon offsets. 💚 What Is Greenwashing? Greenwashing is when a company or product pretends to be more environmentally friendly than it really is — using marketing spin, misleading labels, and vague claims to make you feel good about buying something that’s… well, not all that green. It’s like putting a solar panel on a diesel truck and calling it “eco-aware.” 🧼 Common Greenwashing Tactics to Watch For 1. Vague Claims Words like: Eco-friendly Susta...

Heat Pumps vs British Weather – Who Wins When It’s Cold AND Damp?

  Heat Pumps vs British Weather – Who Wins When It’s Cold AND Damp? ( Spoiler: It’s Closer Than You Think ) When we first installed our air source heat pump , I imagined cosy winter evenings, warm radiators, and smugly low heating bills. What I didn’t quite picture was the battle of the century: Heat Pump vs British Weather (Round 1: Cold and Damp – because why choose?) The British climate is, let’s face it, passive-aggressive . One minute it’s 12°C and drizzly, the next it’s -2°C with “feels like minus ten” wind. Not exactly ideal conditions for pulling heat from the air. So… how does a heat pump hold up? Let’s get real. ❄️ But Wait… Can a Heat Pump Cope with the Cold? Yes. Just… slower. Heat pumps work by extracting warmth from the air , even in low temperatures. In fact, modern heat pumps work efficiently down to -15°C , which is colder than your average British grumble. But there’s a catch: The colder it gets , the harder it has to work. The damp makes t...
