Investors choosing between State Street SPDR MSCI ACWI Climate Paris Aligned ETF (NASDAQ:NZAC) and iShares Core MSCI Emerging Markets ETF (NYSEMKT:IEMG) must weigh a global climate-tilted strategy against broad emerging markets exposure.

Both funds provide international equity exposure but with fundamentally different goals. NZAC targets a "net-zero" strategy by filtering global stocks for climate risk, while IEMG serves as a low-cost cornerstone for investors seeking large-, mid-, and small-cap companies specifically within developing nations.

What this means for investors

These two funds rarely end up in the same conversation, and for good reason: They are built for entirely different investors with entirely different goals. NZAC is a global fund spanning both developed and emerging markets, but its defining feature is its climate mandate. It tracks an index aligned with the Paris Agreement, overweighting companies positioned for the low-carbon transition and reducing exposure to high-emission industries. The result is a broadly diversified global portfolio with an environmental lens built in.

IEMG has no climate screen whatsoever. It tracks the full MSCI Emerging Markets index (China, India, Taiwan, South Korea) capturing the growth potential of developing economies regardless of their carbon footprint. That breadth includes energy companies, heavy industry, and state-owned enterprises that NZAC would downweight or exclude entirely.

The fee difference between them is modest, but the philosophical gap is enormous. NZAC suits investors who want global equity exposure aligned with their environmental values. IEMG is the better fit for those making a deliberate bet on emerging market growth without any values-based filter applied.
