The Greta effect

More Swedes are staying on the ground because of “flight-shame”

GRETA THUNBERG is currently afloat somewhere on the Atlantic Ocean. The 16-year-old Swedish climate-change activist is sailing from Britain to New York, where she will attend the UN’s Climate Action Summit. With cramped quarters, no toilet and the potential for rough seas, the two-week voyage will be uncomfortable. Ms Thunberg has described the experience as “camping on a rollercoaster”. By air, the journey would take just eight hours. But because of the greenhouse-gas emissions associated with air travel, she refuses to fly.
