Every few years I visit CES (formerly the Consumer Electronics Show) in Las Vegas, a goliath event that is equal parts shameless spin and publicity, trade show and business conference. I’m an atmospheric scientist, and I want to get some insight into the technologies that might reduce our personal emissions in future.
In 2018, there was an explosion in interest in air-quality sensors alongside products aimed at cleaning air in the home. I wondered back then whether air filtration would gain traction in Europe and whether this was environmentally sustainable or socially equitable.
That was in a pre-COVID world. While indoor air filters still aren’t ubiquitous, I see far more today than I’d have predicted in 2018. My futurologist skills are pretty poor.
