Is there a greener way to fly? We know that air travel is bad for the planet, with emissions from the aviation industry contributing substantially to global warming. But it is impossible to imagine a future without flying – at least every now and again. So how can we solve this dilemma? If ongoing work to develop electric planes succeeds, then by 2030 we could all be flying more sustainably. In this episode we take a closer look at the efforts to make electric passenger aircraft a reality, and find out what we can do in the meantime to travel in greener ways.
