Most large companies now tie some executive pay to ESG performance, but the design choice that determines whether it changes behavior is structural: whether the metrics sit in the short-term incentive plan (STIP), the long-term incentive plan (LTIP), or both, and how much weight they carry. Evidence points to a clear pattern. Short-term plans are the more common home for ESG metrics, but incorporating them into LTIPs is considered a leading practice because it aligns with the long-term nature of sustainability goals and the larger share of compensation those plans represent. Weighting matters just as much: around 20% is common, 30% on material issues is considered best-in-class, and weights as low as 2–5% risk being read as greenwashing.

Choosing Your Incentive Horizon: STIP vs. LTIP for ESG Metrics

The first design decision is which plan houses the metric, and it should follow from the nature of the objective. A STIP scorecard, measured on annual performance, suits operational goals a leadership team can move within a year. An LTIP suits transformation goals whose outcomes unfold over multiple years and where the payoff horizon matches the strategy's own horizon.

According to Dominik Legault and Yan Vermeulen, writing for Odgers, incorporating ESG measures into LTIPs is considered a leading practice because it "aligns well with the long-term nature of many ESG metrics and typically constitutes a larger proportion of an executive's compensation package, fostering a stronger commitment to sustainable business practices." That size advantage matters: a metric placed in the plan that carries more of the executive's total pay has more leverage over behavior.

There is also a hybrid path. Some companies link the two plans through front-end performance conditioning, in which annual STIP performance influences the size of LTIP grants. Odgers identifies organizations including major banks, Canadian Natural Resources Limited, and Canadian Apartment Properties REIT as using this approach, which lets annual ESG results modulate long-term rewards without requiring fully quantified multi-year targets.

Adoption, however, is uneven. A Conference Board analysis, discussed by Matteo Tonello on the Harvard Law School Forum on Corporate Governance, notes that limited adoption of ESG metrics in long-term plans reflects challenges in setting credible long-term targets, including data limitations, evolving ESG criteria, and potential misalignment with traditional financial goals. The same analysis suggests integration into long-term plans may increase as companies build ESG data capabilities and respond to expanding mandatory sustainability reporting requirements in the US and internationally.

ESG Incentive Plan Decision Framework

The matrix below organizes the core design choices. Read it by first identifying whether your priority is immediate operational change or long-term strategic transformation, then mapping the weighting strategy to that path.

Decision matrix: matching ESG objectives to incentive plan structure and weighting
Design dimensionSTIP path (operational focus)LTIP path (strategic focus)
Best-fit objectiveAnnual, operationally controllable ESG goalsMulti-year transformation goals matching the long-term nature of many ESG metrics
Strategic alignmentDrives immediate operational changes within the annual cycleEmbeds sustainable business practices into the larger share of executive pay
Target robustnessTargets can be less robust and transparent than LTI targets, per WTW's payout analysisGenerally more robust and transparent targets, though long-horizon climate targets are harder to set
Typical weightingCommonly around 20% of the scorecard; 30% on material issues is best-in-classSame weighting benchmarks apply; front-end conditioning can link STIP results to LTIP grant size
Key riskSmall ESG components of short-term bonuses may be immaterial to total payCredible long-term targets are difficult to set amid data limitations and evolving criteria

The weighting benchmarks come from Odgers: a 20% weight in executive compensation scorecards is common, while 30% on material ESG issues is considered best-in-class. The framework's logic is that plan type determines the horizon and pay leverage, while weight determines whether the metric is significant enough to change decisions.

Crafting Meaningful Weights for ESG Metrics

Weighting is where good intentions most often fail. The scale of the problem is visible in a widely cited example from an ECGI working paper: Microsoft CEO Satya Nadella's annual incentive award made up only about 18% of his nearly $55 million compensation package, and the ESG component of that award was only a little over two percent of his total compensation. At that level, even strong performance on the metric barely moves total pay.

Research published by HEC Paris sharpens the point: in sectors where ESG improvements align with financial performance, companies use material ESG incentives, but in industries without an obvious link between ESG and financial results, ESG-linked pay "remains immaterial and may function as a response to external pressures from investors, regulators, or the public." The study warns this practice risks devolving into greenwashing—presenting a socially responsible image without producing meaningful results.

The practical implication for a design discussion is to work backward from materiality. A weight that would change an executive's decisions if the target were missed is meaningful; a weight that would not is decoration. The 20% common benchmark and 30% best-in-class benchmark give a defensible starting range, with the higher figure reserved for issues genuinely material to the business.

Avoiding Greenwashing: Transparency and Measurability

Weight alone is not sufficient if the target is vague. Sustainalytics, reviewing recent disclosures, found that 76% of the largest publicly traded companies embedded some type of ESG metric into leadership compensation in 2023, up from 66.5% in 2021—but that many of the compensation schemes lacked clearly defined and measurable targets, creating ambiguity over what executives were being rewarded for achieving.

That ambiguity is the mechanism by which ESG-linked pay fails. If a scorecard says "improve sustainability performance" without a quantified threshold, the incentive rewards whatever interpretation the compensation committee later adopts. Odgers makes the same connection from the design side: higher weighting is particularly effective when it is clearly defined and linked to quantifiable targets, ensuring ESG goals are both significant and measurable within the overall compensation structure.

WTW's comparative analysis of payouts adds a nuance worth raising in any design discussion: quantifiable metrics may show lower payout trends because targets are more stretching and performance assessments more rigorous. In other words, demanding measurability may reduce payouts relative to softer metrics—and that is a feature, not a flaw, if the goal is genuine change.

Implementation Considerations and Challenges

Three practical challenges recur across the evidence. First, long-horizon target setting is genuinely hard: WTW's analysts note that climate-related targets over longer performance periods are more difficult to set due to the volatile and non-linear nature of carbon reduction strategies. A company choosing the LTIP path should expect to invest in scenario work before committing to numbers.

Second, metrics must be tailored to the role. The HEC Paris research calls for a more transparent and genuine approach using ESG criteria adequately tailored to specific managerial responsibilities, because generic metrics can misalign accountability with actual control over outcomes.

Third, plan choice interacts with data maturity. The Conference Board analysis links limited LTIP adoption to data limitations and evolving ESG criteria, suggesting that companies earlier in their ESG data journey may reasonably start with STIP metrics or front-end conditioning while building toward LTIP integration.

One caveat throughout: this is a structural design discussion, not legal or financial advice, and the benchmarks here describe market practice rather than a recommendation of specific metrics for any particular company or industry.

Making Your ESG Compensation Plan Impactful

To ensure ESG metrics in executive compensation actually drive sustainability goals, prioritize aligning the incentive plan type with the nature of your ESG objectives—STIP for operational, LTIP for strategic—and commit to material, clearly defined, transparent targets with meaningful weights. The measurable indicator of success is a higher proportion of executive compensation linked to material ESG targets, moving toward the roughly 30% weighting Odgers identifies as best-in-class, alongside a reduction in stakeholder criticism of greenwashing or vague ESG commitments in proxy statements. The next milestone to watch is the expanding mandatory sustainability reporting requirements in the US and internationally, which the Conference Board analysis expects to push more ESG metrics into long-term plans.
