The Chicago-based Union of Concerned Scientists is out with a new guide to explain how to reduce your carbon footprint in your own back- and front-yard. Most of the tips you’ve heard before: ditch the gas-powered lawnmower, pesticides, and synthetic fertilizers; plant trees and shrubs to remove CO2 and to shade your home, compost, limit lawns, and the like. But if you’re new to gardening, the green movement, or need a refresher, this nice concise guide will steer you straight. And for chemical-free fertilizer and electric mower recommendations, see Lou Manfredini’s latest column in Chicago Home + Garden’s May/June issue.
