This is a blog for news and views on the future of sustainable cites. A major revamp is in the works. Until then I am keeping this version up as an archive of my past writing.

You can expect occasional updates, but not with the same frequency as in the past.

You can also find my writing on urban redesign and sustainability in ReNew Canada, The Mark, Sustainable Cities Canada, WorldChanging, and other more specialized academic publications.

Info on my consulting work, c.v. and current research focus is all here.
