"Our key findings are:

    •    Optimized carbon-free portfolios closely tracked the U.S. market since 1988 and the global market since 1997
    •    Carbon-free portfolios in markets with large concentrations in Oil, Gas and Consumable Fuels have historically incurred significant tracking error
    •    On average, divesting has transferred assets from the Energy Sector to Utilities and Materials"
