Which Is the Better International ETF: State Street's Climate-Focused NZAC or iShares' Emerging Markets IEMG?

The article compares two international ETFs: NZAC, a climate-focused global fund with over 50% U.S. exposure, and IEMG, an emerging markets fund with true international diversification. IEMG offers lower costs (0.09% vs 0.12%), higher yields (2.3% vs 2.0%), and stronger 1-year returns (33.4% vs 19.8%), making it the better choice for emerging market exposure. NZAC delivered stronger 5-year growth ($1,591 vs $1,444 on $1,000) with lower volatility but behaves more like a climate-filtered U.S. tech portfolio than a true international diversifier.
