Finland’s capital city of Helsinki launched a sustainability app this summer that lets residents, tourists and business owners make smarter daily choices that contribute to the metropolis’ goal of reaching carbon neutrality by 2035. Think Sustainably launched in June 2019 and helps users decide on activities, transportation options and shops by toggling specific sustainability filters to find choices that best suit their preferences and meet environmental metrics. “Individual choices matter,” said Kaisa-Reeta Koskinen, the director of the Carbon Neutral Helsinki Initiative.
