Summary

This document provides a summary of the development, analysis and results of the "What Would it Take?" scenario, which is one of two scenarios in the TPB Scenario Study. This scenario examines what it would take in the National Capital Region to meet aggressive regional climate change mitigation goals in the transportation sector. This report includes a baseline inventory and forecast of carbon dioxide emissions in the region, identification and analysis of potential mitigation strategies, and an analysis of whether any combination of these strategies meets long-term mitigation goals. The report also includes cost-effectiveness analysis of these measures and specifically identifies short-term measures that can be feasibly implemented by local governments in the region.
