Already, some suburban jurisdictions are adapting to new realities, transforming themselves into "urban 'burbs" with pedestrian downtowns, light-rail lines, and new forms of housing. This conscious urbanization is savvy in terms of meeting younger people's preferences, but it's also the only environmentally responsible course. The October 2018 report of the UN Intergovernmental Panel on Climate Change warned that we have only a short window of time until the year 2030-to bring down emissions enough to avoid catastrophic warming, and doing so will require "rapid, far-reaching and unprecedented changes in all aspects of society." Research shows that sprawl-style land use increases greenhouse-gas emissions by decentralizing jobs and services and prompting us to drive more.
