The SPDR MSCI ACWI Climate Paris Aligned ETF (NZAC 1.24%) stands out for its lower cost and tech tilt, while the iShares MSCI ACWI ex US ETF (ACWX 1.76%) offers a higher yield, greater international diversification, and significantly more assets under management.
Both NZAC and ACWX track global equities, but NZAC integrates climate-focused screening and includes U.S. stocks, whereas ACWX holds only non-U.S. companies. This comparison weighs their costs, sector exposures, recent performance, and liquidity to help investors understand which may better fit their goals.

Key Data Points
What this means for investors
Both of these ETFs offer global equity exposure, but NZAC is designed around climate alignment while ACWX focuses purely on geography by excluding U.S. stocks. Investors choosing between the two need to decide whether climate screening or a dedicated international allocation better fits their portfolio strategy.
NZAC holds global companies that meet Paris Climate Agreement targets, screening out fossil fuels and controversial weapons while maintaining broad diversification across developed and emerging markets. The fund charges a 0.12% expense ratio and yields 1.9%, delivering ESG-focused exposure without sacrificing U.S. market participation.
ACWX tracks large- and mid-cap stocks across developed and emerging markets outside the United States, offering investors pure international exposure. With a 0.32% expense ratio, ACWX costs more than double what NZAC charges -- meaning you'll pay higher fees each year. However, ACWX's 2.7% dividend yield delivers considerably more income from the fund's $8.4 billion in assets, potentially offsetting those extra costs for investors prioritizing cash flow.
Ultimately, the choice here hinges on portfolio construction: NZAC suits those seeking complete global coverage with climate considerations, while ACWX works best for those building separate U.S. and international allocations who prioritize dividend income over cost efficiency.
