Most books about saving the planet make you feel guilty before the end of the first chapter. This one makes you laugh. Isabel Losada's revised and expanded edition arrives at exactly the right moment — when environmental fatigue is real, and what people need isn't more data but a reason to actually start.
The Book That Doesn’t Preach
The subtitle says it all: How to Practise without Preaching. Losada is not interested in cataloguing the catastrophe — she assumes you already know things are bad. What she wants to find out is what one ordinary person can actually do, and whether doing it might feel less like punishment and more like a life worth living.
She starts with a small, relatable disaster: losing her temper in a restaurant that refuses to serve her without plastic cutlery. From there, the book takes off in every direction — planting native trees in the Scottish Highlands, switching banks, joining Extinction Rebellion samba circles, interviewing her own energy supplier, reconsidering how she shops, votes, travels, eats, and decorates her home. Every chapter is short. Every chapter covers something real.
This second edition, substantially expanded at 422 pages, adds new material on digital decluttering (apparently your unread emails have a carbon footprint), heat pumps, protecting urban trees, and how environmentalists can engage with the law. Losada is stubborn in the best way: she keeps following threads until she finds something usable.
Joy as Method, Not Marketing
What separates this book from the well-intentioned-but-heavy genre it belongs to is that Losada uses joy as a genuine filter. When she investigates something — ethical banking, organic food, sustainable fashion — she doesn’t just ask “is this better for the planet?” She also asks whether it improves her own life. Often the answer is yes. The chapter on changing banks is particularly good: she goes deep on where her money is actually invested, confronts the absurdity of funding fossil fuels while composting her coffee grounds, and ends up making the switch. It’s funny, specific, and actionable.
The chapter on darkness — what we’ve lost by filling every hour with artificial light — is the one readers seem to remember longest. It’s a good reminder that slowing down and going green are often the same thing.
The greatest threat to our planet is the belief that someone else will save it.
— Isabel Losada, The Joyful Environmentalist
What the Book Doesn’t Do
A fair caveat, and one worth naming: this is a book written from a position of relative comfort. Many of the suggestions — researching every purchase through Ethical Consumer, staying in rural AirBnBs for nature immersion, installing heat pumps — require time, money, or housing conditions that not everyone has. One critical reader on Goodreads put it plainly: environmentalism cannot be seen as a luxury for the affluent. The book doesn’t really grapple with this, and the revised edition apparently doesn’t either.
That’s a real limitation. But it doesn’t erase what the book does well for the readers it’s actually written for: people who want to do more but feel overwhelmed, guilty, and exhausted by the scale of it all. For that reader, this book works.
6 Key Ideas From This Book
Use joy as your compass for which actions to take. If it makes your life better and the planet better, it's a good place to start. Guilt is not a reliable motivator — joy is.
Where you bank is where your money invests. Most high-street banks fund fossil fuels. Switching to an ethical bank is one of the highest-impact changes an individual can make — and Losada walks you through it.
The book's central argument: individual actions do matter — not because one person changes the system, but because millions of small changes compose a different culture. You don't have to save the planet. You just have to do your bit.
Losada joins Extinction Rebellion but plays samba drums at the back. She volunteers, plants trees, and petitions her council. Being a "little bit activist" is a real position, and it's more sustainable than burning out on outrage.
New in the 2025 edition: email inboxes, cloud storage, and streaming all consume energy. Digital decluttering isn't just a productivity move — it has a small but real environmental dimension.
Several chapters return to the idea that the more time you spend in nature — really in it, not just near it — the more natural protecting it becomes. Wilding your garden. Walking without headphones. Sitting in darkness.
Anyone suffering from eco-anxiety who needs a way in — not more doom, but a door.
Zero Waste Home by Béa Johnson for the household deep-dive, and Wilding by Isabella Tree (who blurbs this book) for the land restoration side.
People who already consider themselves environmentalists but have run out of steam. The book is good at re-energising the already-committed, not just converting the sceptical.
UK-centric and assumes a degree of financial flexibility. Some suggestions won't translate easily to different economic contexts or housing situations. Read it for the mindset, not as a literal checklist.
Is The Joyful Environmentalist worth reading in 2025?
Yes — and the revised edition is the right version to read. It's been updated with new material on digital carbon footprint, heat pumps, and legal tools for environmentalists. The tone remains the same: funny, practical, and refreshingly free of lectures.
How does it compare to other sustainability books?
Most sustainability books are either data-heavy (Drawdown) or deeply personal memoir (Braiding Sweetgrass). This one sits in a different lane — narrative non-fiction that's primarily a how-to guide, but written with enough wit and warmth that it doesn't feel like homework.
Is this book too Western or too middle-class?
Honestly, yes — this is a fair criticism. The book is written from a London perspective and many of the specific recommendations (ethical banking, Ethical Consumer ratings, UK energy suppliers) are UK-specific. Readers elsewhere will need to find local equivalents. The mindset, however, travels.
What's new in the 2025 second edition?
The publisher describes it as "fatter" — most of the original content remains, with additions on digital decluttering, heat pumps, protecting urban trees from councils and insurance companies, and how environmentalists can use the law. It's worth reading even if you read the first edition.
The Verdict
The book's argument is simple and it makes it well: going green doesn't have to feel like self-punishment. Losada is funny, honest about her own failures, and genuinely curious — three qualities that are rarer in this genre than they should be. The Western bias is real, and worth knowing going in. But as a guide to building an environmental practice that you can actually sustain, this is one of the best available. Buy it for yourself. Buy a second copy for the friend who's given up.
