SPDR MSCI ACWI Climate Paris Aligned ETF (NZAC 1.00%) and iShares MSCI World ETF (URTH 0.56%) differ on cost, yield, and coverage: NZAC is cheaper and climate-focused, while URTH spans more developed-market holdings, with superior recent performance and liquidity.
Both funds aim to give investors global equity exposure, but their approaches diverge. NZAC tracks a climate-aligned version of the MSCI ACWI index, integrating environmental screens and covering both developed and emerging markets. URTH, in contrast, tracks developed markets only and omits sustainability screens, making this a match-up of climate-conscious breadth versus conventional global reach.

What's inside
URTH holds 1,322 developed-market stocks spanning technology (27%), financial services (16%), and industrials (11%), with top positions in Nvidia (NVDA 1.41%), Apple (AAPL +0.10%), and Microsoft (MSFT 3.90%). Its 13.9-year track record and broad sector spread make it a staple for those seeking developed-markets exposure without climate or ESG overlays.
NZAC, by comparison, holds 687 stocks but covers both developed and emerging markets, with a heavier tilt toward technology (31%). Its top holdings mirror those of URTH but with a climate-focused, ESG-screened approach. This makes NZAC potentially more attractive to investors prioritizing sustainability, although its assets under management (AUM) remain significantly smaller.

Foolish take
From the standpoint of their composition, URTH and NZAC are remarkably similar. As mentioned above, the top three holdings in each fund are identical, and their respective weights in the portfolio are also similar. That said, even expanding out to the top 10 holdings, the commonalities are stark.
The primary difference between these funds lies in their stated goals. While URTH offers exposure to a broad range of international stocks, NZAC has an explicit focus on investors who want to reduce their exposure to climate risk, hence the reference to the Paris Climate Agreement in the fund's name. Each investor needs to decide if that distinction matters to them.
The distinguishing factor that could have the most significant impact on investors' returns is the difference in fees between these funds. With an expense ratio double that of NZAC, URTH doesn't appear to offer much by way of performance to justify the difference in fees.
Unless an investor has a clear desire to invest in or avoid a climate-focused ETF, the similarities between these funds make the fee the most important factor to consider when choosing where to invest their dollars. Over the long term, two funds with similar performance will yield noticeably divergent results for investors due to the difference in fees.
