Chatter about emoji might seem frivolous. But whether it’s a drop of blood symbol helping to lift the taboo around periods or adding emotional context to conversations that have moved online during lockdown, emoji play a crucial role in modern culture. Like gifs, memes and other cultural references, emoji are part of how we talk to each other today. As such, it only seems sensible that the ever growing emoji vocabulary should include symbols relating to climate change. There’s an oil drum, a gas pump and a power station, so why nothing relating to green tech?
