A new study from the University of Southern Denmark shows that if we all bicycled as the Dutch do, annual global carbon emissions would drop by 686 million tons per year. That is more than the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia, and Australia. The UK climate organization Hubbub says that around 50% of our daily journeys are less than two miles (3.2 kilometers). But while cycling bloomed during the pandemic, it still only accounts for five percent of daily trips worldwide. Lessons we can learn from Denmark and the Netherlands "include, but are not limited to, for example, proper bicycle lanes planning and construction, pro-bicycle education and culture, and policies to discourage car use through tax," the study says.
