The newest issue of the David Report adds more fuel to the smokin' hot topic of sustainability by discussing the outcome of green event Designboost, which recently took place in Malmö, Sweden. The Sustainable Wheel (it's imaginary, not physical like in The Price is Right) is a concept that emerged from the multi-faceted event as a guide or tool of sorts for designers, companies and organizations to easily define what sustainable design means for them. The system is upheld by seven factors: environmental influence, innovation, emotional connection, aesthetics, quality, authenticity, and compatibility--and like any wheel, it's as strong as it's weakest spoke. The report also includes a brief interview with Jennifer Leonard, a designer researcher and writer at IDEO who presented at Designboost.
