The iShares Paris-Aligned Climate Optimized MSCI USA ETF (the Fund ) seeks to track the investment results of an index composed of U.S. large- and mid-capitalization stocks that is designed to be compatible with the objectives of the Paris Agreement by, in aggregate, following a decarbonization trajectory, reducing exposure to climate-related transition and physical risks and increasing exposure to companies favorably positioned for the transition to a low-carbon economy.
The fund tracks the MSCI USA Climate Paris Aligned Benchmark Extended Select Index using representative sampling, holding a sample of securities designed to reduce greenhouse gas intensity by at least 50% relative to the broad U.S. market while maintaining sector exposure to climate-transition industries. The index excludes companies involved in tobacco, weapons, firearms, thermal coal, oil and gas, and severe environmental or governance controversies. Because the fund samples rather than holds all index constituents, its returns may diverge from the index.

How it has done
PABU share class · total returns with dividends reinvested
Volatility over the last 12 months: 15.42%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 and Aug 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
