Ecotopias I recommend

Here are the ecotopia books I have read and recommend:

• A Half-Built Garden – Ruthanna Emrys (best one)
• A Psalm for the Wild-Built – Becky Chambers (+ its sequel A Prayer for the Crown-Shy, they are really short!)
• METAtropolis – edited by John Scalzi; specifically “The Desire Lines”, although it’s a good set of short story collections
• Ecotopia – Ernest Callenbach (1990)
• Arboreality – Rebecca Campbell

Not so much ecotopia, but eco-sci-fi

• City – Clifford D. Simak
• The Nitrogen Fix – Hal Clement
• Semiosis – Sue Burke
• The Many Selves of Katherine North – Emma Geen

Ecotopias, but I don’t recommend them

• Another Life – Sarena Ulibarri
• Emergency Skin – N.K. Jemisin
• The Fifth Sacred Thing – Starhawk (magical??)
• The Word for World Is Forest – Ursula K. Le Guin

Ecotopias I haven’t read yet, but maybe they are good

• The Ministry for the Future / Pacific Edge / Blue Mars – Kim Stanley Robinson
• Stealing Worlds – Karl Schroeder
• The Tusks of Extinction – Ray Nayler
• Meru – S.B. Divya
• Blue Remembered Earth – Alastair Reynolds
• Be the Sea – Clara Ward

Nonfiction, but about getting to ecotopia in a way

• The Once and Future World: Nature As It Was, As It Is, As It Could Be – J.B. MacKinnon
• Wild Souls – Emma Marris
• Abundance – Ezra Klein & Derek Thompson
• The Synthetic Age – Christopher J. Preston
• Ghosts of Evolution – Connie Barlow
• Living Through the End of Nature – Paul Wapner (philosophy exploring both extremes)

The whole list

I’ve also got a list of nonfiction about novel ecologies, rewilding, and so on. Here is my entire 135-book list of ecological books – of which I have read about three quarters!
