Mayor Katjana Ballantyne's leadership on environmental issues has made Somerville a recognized leader in climate change mitigation, urban ecosystem restoration, and carbon footprint reduction. She’s implemented many ground-breaking initiatives to address these critical issues. Examples are Mayor Katjana’s first-ever Pollinator Action Plan to protect native pollinators, building on Somerville’s Native Species Ordinance, which she introduced as a City Councilor. These are a first of a kind plans for a dense, urban city like ours, and have already become models for similar cities across the country.
