This document summarizes a life cycle assessment report that compares the environmental impacts of teleworking (working partially from home) versus non-teleworking (working full-time in the office) for Telstra employees. The report finds that teleworking has lower environmental impacts for global warming, abiotic depletion, and photochemical oxidation, but higher impacts for human toxicity. A sensitivity analysis shows the key parameters that influence the results are commuting distance, how quickly office space is consolidated, and energy efficiency of home offices.
