Large cities may cut emissions by a third based on improvements in housing density alone. Reducing driving is essential

Patrick Sisson at Curbed pointed out recently that some studies have estimated that large global cities could cut their emissions by a third based on improvements in housing density alone. We have to start talking about these solutions and making them part of mainstream environmental policy, Hankins says. Time is running out. “We can’t afford to ignore significant climate mitigation measures just …
