We have less than seven years to dramatically alter our future. Under our year-long Vision 2020 program, we have conferred with building industry experts to establish a timeline critical goals and metrics we must establish and meet by the year 2020 in order to preserve our environment and meet large-scale goals such as those of the 2030 Challenge. Scroll over points in the timeline below, which has been updated for 2013, to learn more about the path ahead in green building. Then, visit Ecobuildingpulse.com/Vision-2020 to learn more about what we uncovered in this year's program.
