Veganuary is an annual challenge run by a UK nonprofit organisation that promotes and educates about veganism by encouraging people to follow a vegan lifestyle for the month of January. Since the event began in 2014, participation has increased each year. 400,000 people signed up to the 2020 campaign. The campaign estimated this represented the carbon dioxide equivalent of 450,000 flights and the lives of more than a million animals. Veganuary can also refer to the event itself.
