CRBNBiShares Low Carbon Optimized MSCI ACWI ETF

IOOBiShares Global 100 ETF

In short

CRBN Keeps the whole world in the basket, then leans it away from carbon. CRBN tracks an MSCI ACWI index built for lower carbon exposure, with screens on thermal coal, oil sands and controversial weapons.

IOO Global investing boiled down to 100 mega-caps. Running since 2000, IOO tracks the S&P Global 100: blue chips that already sell on every continent, rather than the whole world's market.

Stated mandate

CRBN The fund seeks to track global equities through an index designed to have lower carbon exposure than the broad market, while applying screens for controversial weapons, oil sands, and thermal coal mining.

IOO The Fund seeks to track the investment results of an index composed of 100 large-capitalization global equities.

Why people hold it

CRBN Costs 0.20% a year, well under the 0.45% median for its index-wrapper cohort. Cheap for a screened, optimized mandate.
Not a niche slice. Roughly 1,100 stocks worldwide, so the carbon tilt sits on top of a whole-world equity core.
The rulebook is named out loud: the MSCI ACWI Low Carbon Target Index, plus stated exclusions. Portfolio and mandate line up tightly, top quartile among its peers.ishares.com
Trading since 2014, a long tenure for a climate-screened index fund, and a multi-billion-dollar fund today.

IOO Launched in 2000, one of the original global blue-chip index funds, and a multi-billion-dollar fund today.
Straight indexing, no manager discretion. It has tracked the S&P Global 100 very closely.ishares.com
At 0.40%, it runs a touch under the typical index wrapper in its peer group.
One ticket for global large-cap equity instead of bolting a US fund to an international one.

Worth knowing

CRBN Thinly traded next to the household-name global index funds, so bid-ask spreads and order type matter more here.
The carbon tilt carries a price. VT wraps global stocks for 0.06%, roughly a third of the cost.
Cash comes back once or twice a year, not quarterly or monthly.

IOO About 100 names, so a handful of mega-caps do the heavy lifting. Broad wrappers like VT own thousands.
0.40% is real money beside the broad-index cheapies: VT at 0.06%, SCHK at 0.03%.
Income lands once or twice a year, not monthly, and volume is moderate rather than heavy.
