Fossil Fuels Reserve (%)

For Stocks:
This field identifies companies with evidence of owning fossil fuel reserves regardless of their industries, including companies that own less than 50% of a reserves field. 100% indicates there is evidence of owning fossil fuel reserves, and 0% indicates there is no such evidence. Fossil reserves are defined as proved and probable reserves (i.e. 1P and 2P) for coal and proved reserves (i.e. 1P) for oil and natural gas. Evidence of owning reserves includes companies providing the exact volume of reserves, and companies making a statement about their ownership of reserves.

For ETFs/Mutual Funds:
The percentage of portfolio's market value exposed to companies that own fossil fuel reserves.

For Model Portfolios:
The percentage of portfolio's market value exposed to companies that own fossil fuel reserves. This is calculated by finding the weighted mean of the holdings' fossil fuels reserve % with the weights that have available data coverage. There's a 65% data coverage threshold requirement for the data point's calculation.

Formula

(Holding1 exposure % * Holding1 weight) + ... + (HoldingN exposure % * HoldingN weight) / (Holding1 weight + ... + HoldingN weight) = Portfolio Exposure %
