Both the State Street SPDR MSCI ACWI Climate Paris Aligned ETF (NZAC 1.15%) and iShares Core MSCI Emerging Markets ETF (IEMG 2.67%) target global equity exposure, but their approaches diverge: NZAC aims to align with climate goals across developed and emerging markets, while IEMG focuses on emerging-market equities. This comparison examines their cost, performance, risk, sector tilts, and structural quirks to help investors decide which may better fit their portfolio goals.

What this means for investors
IEMG seems to have better performance in various performance measures compared to NZAC, but that doesn’t mean the sustainability-focused ETF doesn’t have value. With various countries around the world progressing toward the pledges they made in the Paris Agreement. And as demand for climate change efforts worldwide increases, companies that have not yet passed the ESG screening may eventually meet the criteria to keep up.
One advantage that NZAC could potentially have over IEMG is its weaker international influence. For U.S. investors, that can be beneficial if they’re not familiar with international assets, as they are often more volatile and move significantly different from U.S. stocks.
While NZAC does have foreign assets, its top U.S. holdings currently hold enough weight to not be too impacted if a major foreign event were to occur in Asia and/or Europe. But for overall global tech exposure, both funds aren’t bad options.
