NZAC vs. ACWX: One Climate-Aligned Global ETF vs. One International ex-U.S. ETF

Meta description: NZAC vs. ACWX is a practical choice between a climate-screened global equity ETF that includes U.S. stocks and an international ETF that excludes the U.S. Here’s a detailed, investor-friendly breakdown of cost, yield, diversification, holdings, risk, and how each fund fits a portfolio in 2026.

Investors often say they want “global diversification,” but that phrase can mean very different things depending on how a fund is built. Two popular ETFs can look similar at first glance—both hold large baskets of stocks from around the world—yet they serve different goals. One is designed to align a portfolio with climate goals. The other is designed to remove U.S. stocks so you can build a separate international slice next to your U.S. holdings.

This article rewrites and expands on the Motley Fool comparison published on January 17, 2026, which highlights how NZAC and ACWX differ in fees, income, sector mix, performance, and liquidity. We’ll keep it simple, thorough, and practical—so you can actually use it when you’re picking ETFs.

1) The 2026 Snapshot: Cost, Size, Income, and Performance

Let’s start with the cleanest, most decision-friendly facts from the comparison. The Motley Fool summary shows both ETFs offer broad global stock exposure, but they differ sharply on fees, yield, and fund size.

Key metrics side-by-side

NZAC (SPDR MSCI ACWI Climate Paris Aligned ETF) is designed around climate alignment and charges a low fee. ACWX (iShares MSCI ACWI ex U.S. ETF) focuses on international markets and is much larger.

• Expense ratio: NZAC 0.12% vs. ACWX 0.32%
• Dividend yield: NZAC about 1.9% vs. ACWX about 2.7%
• Assets under management (AUM): NZAC about $182 million vs. ACWX about $8.4 billion
• 1-year return (as of 2026-01-09 in the article snapshot): NZAC 22.0% vs. ACWX 34.2%
• Max drawdown (5 years): NZAC -28.29% vs. ACWX -30.06%
• “Growth of $1,000” over 5 years (article figure): NZAC $1,501 vs. ACWX $1,267

Even if you only read the bullet list above, you can already see the story: NZAC is cheaper and (in the article’s five-year lookback) had stronger growth, while ACWX pays more income and is a bigger, more liquid fund. Those differences can shape how you use each ETF in a portfolio. (Source: Motley Fool comparison article, Jan 17, 2026.)

2) What Each ETF Is Trying to Do (and Why That Matters)

NZAC’s mission: climate-aligned global exposure (including the U.S.)

NZAC is built around the idea that climate risk is financial risk. Instead of simply holding the entire global market, it screens companies to better align with the goals of the Paris Agreement, which aims to keep global warming “well below 2°C” and pursue efforts to limit it to 1.5°C. That agreement is a major reference point for climate policy and many climate-focused investment frameworks.

Practical meaning: NZAC tries to keep broad diversification while filtering out (or reducing exposure to) certain categories such as fossil fuels and controversial weapons, based on its index approach. In other words, it’s a “global core” idea—but with a climate lens.

ACWX’s mission: international diversification without U.S. stocks

ACWX is about geography, not climate screening. Its defining feature is simple: it holds large- and mid-cap stocks across developed and emerging markets outside the United States. Investors often use an “ex-U.S.” fund like ACWX when they want to decide their U.S. allocation separately (for example, pairing a U.S. total market ETF with an international ETF).

Practical meaning: ACWX can be a clean building block for a two-fund or three-fund style portfolio, where you control the U.S. vs. international split directly.

3) What’s Inside: Holdings, Sectors, and “Hidden” Bets

All ETFs make “bets,” even passive index ETFs. Those bets come from index rules. When you change the rules—like adding climate screens, or removing a whole country—you can change the ETF’s behavior in ways that aren’t obvious until you inspect the portfolio.

ACWX: broad international basket with financials and industrials weight

According to the Motley Fool article, ACWX holds around 1,700 stocks and has a long operating history (about 17 years at the time of the article). It also notes ACWX’s largest sector weights as:

• Financial services: ~25%
• Technology: ~15%
• Industrials: ~15%

Top holdings cited include Taiwan Semiconductor Manufacturing (TSMC), Tencent, and ASML. This is typical of a global ex-U.S. basket: heavy representation from international financial firms plus major non-U.S. tech leaders.

Interpretation: ACWX is a “true” non-U.S. allocation. If the U.S. market is soaring while other regions lag, ACWX can look weaker. If international markets have a strong run, ACWX can shine.

NZAC: technology-leaning global basket, includes U.S. megacaps, adds climate screening

NZAC is described as having a stronger technology tilt—the article highlights a technology weight around 35%, and it includes U.S. giants such as Nvidia, Apple, and Microsoft. That matters because U.S. mega-cap tech can dominate global index returns in certain market cycles.

On top of that, NZAC applies an ESG screen aligned with climate goals and tracks a “Paris aligned” climate index framework. MSCI’s Climate Paris Aligned methodology describes exclusions and constraints that can include areas such as controversial weapons, severe environmental controversies, and revenue thresholds tied to oil & gas or certain power generation sources. That approach aims to reduce exposure to transition risks (like regulations, carbon pricing, or stranded assets) while maintaining broad market exposure.

4) Fees vs. Yield: The Tradeoff Most Investors Feel First

Fees and dividends are often the first thing investors compare because they’re easy to see and they affect outcomes directly. Still, it’s important to keep perspective.

Why the expense ratio gap matters

NZAC’s expense ratio is 0.12% while ACWX’s is 0.32%. That’s a difference of 0.20% per year. On $10,000 invested, that’s about $20 more per year in fund fees for ACWX (not counting market movement). On $100,000, it’s about $200 more per year. Over many years, that can add up—especially if returns are similar.

Why ACWX’s higher yield may compensate (for some investors)

The flip side is income. In the Motley Fool comparison, ACWX’s dividend yield is around 2.7%, higher than NZAC’s around 1.9%. If your priority is cash flow—maybe for rebalancing, living expenses in retirement, or a dividend-focused strategy—you might accept a higher fee to get a higher distribution stream.

Important nuance: Dividend yield isn’t “free money.” A distribution reduces the fund’s net asset value when it’s paid. Still, dividends can matter for investor behavior and for certain tax and planning situations.

5) Diversification: “Global” Can Mean Two Different Things

Both funds are diversified, but the type of diversification differs.

ACWX diversifies by removing the U.S.

ACWX offers a clean way to diversify away from the United States. If your portfolio is heavily U.S.-centric—like many portfolios are—ACWX may reduce that home-country bias. It also gives you broad coverage across developed and emerging markets in one fund.

NZAC diversifies by keeping the U.S. while screening for climate alignment

NZAC keeps U.S. exposure, which can be a big deal because U.S. mega-caps often drive global benchmarks. The fund’s pitch is: “You can have a global equity core while also applying climate-aligned rules.” That can be appealing if you want climate considerations but don’t want to carve the U.S. out of your global allocation.

6) Risk and Drawdowns: Similar Pain in Bad Times

During market stress, investors care less about fine details and more about one blunt question: “How much can this thing drop?” The Motley Fool comparison reports five-year max drawdowns of about -28.29% for NZAC and -30.06% for ACWX. That’s broadly similar.

What max drawdown can tell you

Max drawdown measures the worst peak-to-trough drop in a time window. Similar drawdowns suggest these funds can both get hit hard during global equity sell-offs. That makes sense: both are equity-heavy and diversified. Neither is designed to be a “crash-proof” product.

Why risk can still differ even with similar drawdowns

Two funds can share similar drawdowns but behave differently in normal markets. NZAC’s tech tilt and inclusion of U.S. megacaps can change its return pattern. ACWX’s stronger financials and industrials weight can change sensitivity to interest rates and global economic cycles. So, drawdown is a useful indicator—but not a full personality profile.

7) Liquidity and Fund Size: ACWX Has a Big Practical Edge

ACWX is far larger by assets under management. In the Motley Fool snapshot, ACWX has about $8.4 billion versus NZAC’s roughly $182 million. That’s a major gap.

Why AUM often matters

• Tighter spreads: Larger ETFs often have tighter bid-ask spreads, making trading cheaper.
• Higher trading volume: It can be easier to buy/sell without moving the market price.
• Lower closure risk: Small ETFs can be more at risk of shutting down if they don’t gather assets.

Reality check: A smaller ETF can still be perfectly fine, especially for long-term buy-and-hold investors. But if you trade frequently or move large amounts of money, liquidity becomes more important.

8) Which ETF Fits Which Investor? Clear Use Cases

This is where the decision becomes personal. You’re not just picking a fund—you’re choosing a role in your portfolio.

Choose NZAC if you want a climate-aligned “one-ticket” global core

• You want global exposure including the U.S.
• You prefer a lower fee structure
• You care about climate screens and want them built into your core ETF
• You’re comfortable with a tech-leaning portfolio profile

Choose ACWX if you’re building a clear U.S. + international split

• You want international stocks only (no U.S.)
• You like a fund with large AUM and high liquidity
• You prioritize dividend yield/income more than ultra-low fees
• You want one fund that covers developed + emerging markets outside the U.S.

9) The Big Picture: What the Motley Fool Article Is Really Saying

The Motley Fool’s conclusion is straightforward: both ETFs provide global equity exposure, but they answer different portfolio questions. NZAC is built around climate alignment, screening out certain industries while keeping broad global coverage (including the U.S.). ACWX is built around geography, giving you international exposure only—at a higher fee, but with higher yield and far greater scale.

If you’re choosing between them, the “right” answer is less about which fund is “better,” and more about whether you’re prioritizing climate screening in a single global fund or a dedicated international allocation that excludes the U.S. (Source: Motley Fool comparison article, Jan 17, 2026.)

FAQs (Frequently Asked Questions)

1) Is NZAC an “ESG ETF” or a “climate ETF”?

It’s best described as a climate-aligned ETF that uses a rules-based approach designed around climate goals (often discussed in the context of Paris alignment). It may use ESG-style exclusions (like controversial weapons) as part of that framework, but the headline goal is climate alignment.

2) Why does ACWX cost more than NZAC?

Funds can have different operating costs, index licensing costs, and business decisions by the issuer. In this comparison, ACWX’s expense ratio is higher (0.32% vs. 0.12%). That doesn’t automatically mean it’s “worse,” but it does mean you should be sure you want what ACWX uniquely provides: ex-U.S. exposure, higher yield, and large scale.

3) Does higher dividend yield mean ACWX will outperform?

No. Yield is only one part of total return. Total return includes price changes plus dividends. A higher yield can be helpful for cash flow, but performance depends on many factors like region, sector, currency moves, and market cycles.

4) Can I hold both NZAC and ACWX together?

You can, but be aware of overlap and what you’re trying to achieve. Since NZAC includes U.S. stocks and ACWX excludes U.S. stocks, holding both can tilt your portfolio toward non-U.S. stocks relative to NZAC alone—depending on how much you allocate to each.

5) Which one is better for beginners?

For many beginners who want one simple fund for global stocks, a global fund that includes the U.S. can feel easier. But “better” depends on your plan. If you’re intentionally pairing a U.S. ETF with an international ETF, ACWX can fit neatly as the international piece.

6) Are climate-screened ETFs guaranteed to be greener in the real world?

No guarantee. Screening changes what you own, but real-world impact is complex. Some investors choose climate-aligned ETFs to manage transition risk or align with values. Others prefer engagement and voting approaches. The key is to understand the ETF’s rules and decide if they match your goals.

Conclusion: A Simple Decision Rule You Can Actually Use

If you want a climate-aligned global ETF that still includes U.S. market leaders—and you care about low fees—NZAC is built for that job. If you want a dedicated international fund that excludes the U.S., pays a higher yield, and offers much deeper liquidity—ACWX is the cleaner tool.

In other words, don’t ask only “Which one performed better recently?” Ask: “Which one matches how I’m building my portfolio?” When you match the fund to the job, you make a calmer, smarter decision—especially when markets get noisy.
