  1. Overview

    by Michael W. Toffel

    My research examines how companies strive to increase operational discipline, primarily in terms of environmental management and performance, but also with respect to occupational safety and process quality. Most of my research papers have addressed two related questions: (1) Why do some companies adopt a more proactive environmental strategy than others?, and (2) Which environmental management approaches are particularly effective in improving environmental performance, and why?

  2. Managing sustainability in supply chains

    by Michael W. Toffel

    I am examining codes of conduct, management process standards, and government voluntary programs that address environmental and labor issues, seeking to understand what enables some of these programs to actually deliver on their promise of distinguishing organizations as possessing superior management practices and operational performance.Current research projects in this domain include investigations of the following questions:
    • Under what circumstances do social audits of factories lead to sustained improvements in working conditions? How do social audit team characteristics affect operational improvements?
    • Why are some suppliers more willing than others to disclose to their buyers their carbon footprint and vulnerability to climate change? (working paper)
    • To what extent can private-sector governance mechanisms mitigate corruption, and thus excess pollution, in vehicle emissions testing? (working paper)
    • To what extent does adopting the ISO 14001 Environmental Management System Standard affect an organization’s environmental performance? (working paper)
    • To what extent are government policies that mandate green building practices in public construction projects stimulating the private sector green building market? (related: Genzyme Center case on LEED and green building practices)

  3. Corporate transparency and information disclosure strategies

    by Michael W. Toffel

    This research focuses on transparency and information disclosure strategies, a topic of growing importance in environmental sustainability, corporate strategy, stakeholder relations, and public policy.  My prior research in this area explored why some facilities were voluntarily disclosing compliance violations to the US EPA that their internal environmental compliance auditing programs had uncovered. Another article examined why some companies were voluntarily disclosing greenhouse gas emissions and the opportunities and risks they perceived global climate change was posing to their businesses. I have also looked at how managers respond to environmental ratings. My current research projects in this domain address the following questions:
    • What factors lead particular quality problems documented within organizations to garner follow-up problem solving activities? (working paper)
    • Why are some corporations much more transparent in disclosing their environmental performance than others? (working paper)
    • Why are some suppliers more willing than others to disclose to their buyers their carbon footprint and vulnerability to climate change? (working paper)

    Keywords: transparency; disclosure strategy; disclosure; environment; environmental performance; regulation; supply chain; Environmental Sustainability; United States;

  4. Conceptualizing and measuring environmental sustainability

    by Michael W. Toffel

    This research involves developing clarity around the murky construct of environmental sustainability, and improving techniques to measure corporate environmental performance. My prior research in this domain includes clarifying environmental sustainability as a construct, and a case about one company’s sustainability initiative and its approach to greenhouse gas emissions management, and a case about green building that analyzes performance implications of the LEED green building process standard. Other prior work has tested the predictive validity of environmental ratings, and developing better ways to measure environmental performance using Toxic Release Inventory data and to deploy hybrid life cycle assessment techniques.
