A little late I know, but just before the end of the year, we were fortunate enough to be a part of the Sustainable Life Media conference in Miami. As is often the case, the event was full of interesting people extolling the virtues of more sustainable practices - from large MNC’s such as J&J through to some fantastically nimble social start-ups. But more than that, there was a real sense of change in the air. A sense that for the first time we were looking at making businesses sustainable, rather than bringing sustainability into business. In other words, for the first time I sensed that sustainability was being recognised as a key piece of DNA architecture for business, rather than some fan-fared adjunct.The ramifications of this are profound: for a start, this is what Peter Salmon from Moxie (who I had the pleasure to share a plenary session with) has labelled Sustainability 2.0. Or even 3.0. It also suggests an exciting trend that sees sustainability becoming near-impossible to focus on within the firm. That is not to say that it is absent, but rather just invisible. Or rather, inherent. We are constantly hearing clients and colleagues citing an economic downturn as the worst possible time to embark on initiatives under the sustainability banner. But to make this criticism is to make the mistake that sustainability remains an annexe to the firm - an incidental anecdote to be told when appropriate.
