ST. PAUL, Minn. – A law has been proposed in the Minnesota House to ban gas-powered lawn mowers. The bill’s goal: Reduce air pollutants in a step against global warming. The bill was introduced by state representatives Jerry Newton of Coon Rapids and Heather Edelson of Edina, both Democrats. It would require new lawn and garden equipment to be fully electric by 2025. This includes leaf blowers, chainsaws, brush-cutters and lawn edgers. The bill hasn’t found traction yet. There is no companion proposal in the Senate. And even though the Democrat-controlled House has an environment-friendly policy platform, House Speaker Melissa Hortman hasn’t assigned the bill to a committee for an initial review.
