Investors choosing between State Street SPDR MSCI ACWI Climate Paris Aligned ETF (NASDAQ:NZAC) and iShares Core MSCI Emerging Markets ETF (NYSEMKT:IEMG) must weigh a global climate-tilted strategy against broad emerging markets exposure.
Both funds provide international equity exposure but with fundamentally different goals. NZAC targets a "net-zero" strategy by filtering global stocks for climate risk, while IEMG serves as a low-cost cornerstone for investors seeking large-, mid-, and small-cap companies specifically within developing nations.
| Metric | NZAC | IEMG | |---|---|---| | Issuer | SPDR | iShares | | Expense ratio | 0.12% | 0.09% | | 1-yr return (as of May 6, 2026) | 29.00% | 52.10% | | Dividend yield | 1.80% | 2.20% | | Beta | 1.04 | .99 | | AUM | $188.8 million | $155.0 billion |
Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-yr return represents total return over the trailing 12 months. Dividend yield is the trailing-12-month distribution yield.
The iShares fund is the more affordable option with a 0.09% expense ratio compared to 0.12% for the SPDR fund. Additionally, the iShares fund offers a higher trailing-12-month distribution yield of 2.20%.
| Metric | NZAC | IEMG | |---|---|---| | Max drawdown (5 yr) | (28.30%) | (35.90%) | | Growth of $1,000 over 5 years (total return) | $1,591 | $1,437 |
iShares Core MSCI Emerging Markets ETF (NYSEMKT:IEMG) provides exposure to 2,661 holdings across technology (23%), financial services (18%), and consumer discretionary (9%). Launched in 2012, its largest positions include Taiwan Semiconductor Manufacturing at 12.56%, Samsung Electronics at 5.39%, and SK Hynix at 3.87%. The fund has a trailing-12-month dividend of $1.85 per share and tracks an index focused on large-, mid-, and small-capitalization emerging market equities.

These two funds rarely end up in the same conversation, and for good reason: They are built for entirely different investors with entirely different goals. NZAC is a global fund spanning both developed and emerging markets, but its defining feature is its climate mandate. It tracks an index aligned with the Paris Agreement, overweighting companies positioned for the low-carbon transition and reducing exposure to high-emission industries. The result is a broadly diversified global portfolio with an environmental lens built in.
Four leading AI models discuss this article
"NZAC functions more as a US-tech proxy than a diversified climate-impact fund, making its performance correlation to IEMG almost entirely dependent on global semiconductor demand."
The article presents a false equivalence between a thematic ESG overlay (NZAC) and a broad-market beta play (IEMG). Investors must recognize that NZAC is essentially a high-conviction, tech-heavy growth fund disguised as a climate product; its top holdings—Nvidia, Apple, and Microsoft—are identical to a standard S&P 500 growth index. Conversely, IEMG is a geopolitical bet on the Global South, heavily concentrated in the semiconductor supply chain via TSMC. The 29% return for NZAC versus 52% for IEMG highlights a massive divergence: emerging markets are currently capturing a cyclical recovery, while NZAC is merely riding the AI infrastructure boom. Choosing between them isn't about climate vs. growth; it's about US-tech concentration versus EM cyclical exposure.
One could argue that NZAC’s climate-aligned screening acts as a superior risk-management tool, potentially shielding portfolios from the 'stranded asset' risk inherent in the fossil-fuel-heavy indices that IEMG does not filter.
"NZAC's stronger 5-year risk-adjusted returns and regulatory-tailwind climate screens position it superior to IEMG's momentum-driven EM volatility for long-term investors."
Article spotlights IEMG's eye-popping 52% 1-yr return (as of dubious 'May 6, 2026' date—future-dated data raises red flags on accuracy) versus NZAC's 29%, but buries NZAC's edge: 5-yr $1K grows to $1,591 (vs $1,437) with milder -28% max drawdown (vs -36%). NZAC's Paris-aligned screens (714 holdings, 30% tech w/ NVDA 5.9%, AAPL 4.4%) embed low-carbon transition bets amid rising regs, while IEMG's EM tilt (2,661 names, TSMC 12.6%) chases cyclical China/semi surges prone to reversals. Liquidity gap huge (IEMG $155B AUM vs NZAC $189M), but for risk-aware global allocs, NZAC wins long-term.
IEMG's 0.09% fee (vs 0.12%), 2.2% yield, and vast scale enable core EM exposure with less tracking error, potentially compounding higher if demographics/tech adoption propel EM outperformance despite volatility.
"NZAC is mislabeled as 'global climate-tilted'—it's actually a developed-market tech fund with ESG branding, making the comparison to IEMG fundamentally misleading."
The article frames this as a simple choice, but the data screams a different story: IEMG returned 52.1% in one year versus NZAC's 29%—a 23-point gap that dwarfs the 0.03% fee difference. IEMG's $155B AUM versus NZAC's $188.8M suggests the market has already voted. The real tension: NZAC's climate filter excludes high-emission sectors (energy, materials) that have driven EM outperformance, while IEMG captures the full EM cycle. Over 5 years, IEMG's 35.9% max drawdown is worse, but total return ($1,437 vs $1,591) favors NZAC—yet that's before the recent 23-point divergence. The article omits sector composition risk: NZAC is 30% tech (Nvidia, Apple, Microsoft—all developed-market mega-caps), while IEMG is genuinely emerging (TSMC, Samsung, SK Hynix). These aren't comparable global funds.
NZAC's outperformance over 5 years despite lower recent returns suggests the climate filter may have genuine alpha, and the article's recency bias toward IEMG's 1-year surge ignores that mean reversion often punishes crowded EM trades.
"NZAC’s climate-aligned mandate may provide resilience in a policy-driven transition but trades diversification and incurs tracking error versus a broad EM index."
NZAC offers climate-aligned exposure with a Paris tilt, but headline numbers hide risks. A 714-holding screen can distort diversification, potentially concentrating in megacaps (NVIDIA, Apple, MSFT) even as the mandate seeks low-carbon exposure, which increases tracking error versus a broad global index. Climate policy momentum, carbon pricing, or green-tech cycles can swing results—leading to underperformance when energy/materials rebound or when climate-focused rules lag. The article glosses over concentration risk, regulatory tailwinds/headwinds, and begs the question: does small-cap EM exposure with a climate lens actually add resilience or just drag performance? Costs are small but cumulative.
Strong counter-argument: In a world with meaningful decarbonization policy and carbon pricing, NZAC's tilt could offer durable tailwinds and downside protection, making its underperformance in certain regimes less likely than the article implies.
"NZAC's historical outperformance is a relic of a low-rate, pre-commodity-supercycle environment that has fundamentally shifted."
Grok, your reliance on the 5-year total return is misleading because it captures a pre-AI-boom regime that no longer exists. Comparing a $189M fund to a $155B behemoth ignores the massive liquidity premium and implementation shortfall inherent in NZAC. While you highlight drawdown protection, that 'safety' is just a side effect of underweighting the commodity cycle that currently drives EM. You are confusing a structural climate mandate with a temporary tech-beta hedge.
"IEMG's headline returns are distorted by favorable USD strength, exposing it to sharp FX reversals ignored by all."
Gemini nails Grok's backward-looking 5-yr bias, but nobody flags IEMG's crippling currency headwind: 52% USD return masks ~15% EM FX depreciation YTD (e.g., CNY -5%, KRW -8%), inflating 'gains' for USD investors. NZAC's developed-market core sidesteps this volatility trap. If Fed holds rates, EM carry trade unwinds fast—TSMC weight (12.6%) won't save it.
"NZAC's climate mandate isn't risk management—it's a directional bet that underweights the cyclicals driving current EM returns."
Grok's FX headwind is real but overstated. CNY/KRW weakness inflates USD returns ~5-8%, not 15% systematically across IEMG's basket. More pressing: nobody's addressed NZAC's 714-holding screen creating hidden concentration—it's not diversification, it's a filtered mega-cap bet. If climate screens exclude cyclicals, you're not hedging; you're just betting on a regime. IEMG's 52% includes FX noise, but stripping that still leaves 40%+ real EM cyclical gains NZAC missed.
"Regime/policy risk in EM and decarbonization tailwinds could dwarf currency effects; FX is secondary."
Grok, your FX headwind argument is too narrow. The bigger risk is regime risk: policy shifts, debt dynamics, and AI/semiconductor cycles that can flip EM markets regardless of currency moves. NZAC’s megacap tilt reduces certain diversification concerns but invites policy/regulatory exposure in climate/tech cycles. The article underplays tailwinds/tailwinds and relies on currency noise to explain performance; regime risk should be the focal concern.
