How Masdar Measures Climate Outcomes Alongside Financial Returns

Masdar’s green finance reporting lets readers follow money to an Abu Dhabi solar project, see how avoided emissions are estimated and identify where the financial and environmental evidence diverge.

The Al Dhafra solar project in Abu Dhabi has more than one number that an investor might call its impact. Masdar’s 2025 green finance report puts the project’s annual avoided emissions at about 2.16 million tonnes of carbon dioxide. The same report attributes about 432,000 tonnes per year to Masdar’s green bonds. It also shows a cumulative bond allocation of approximately US$38 million to the project. Each number has a different boundary. The first covers the whole project, the second allocates part of the estimate to a source of financing, and the third tracks money.

Mazin Khan, identified as Masdar’s chief financial officer in the report, presents green finance as part of how the Abu Dhabi developer and project investor raises capital. In an earlier published interview, then CFO Niall Hannigan described the first green bond as a step in a wider financing programme. These accounts describe Masdar’s side of the transaction. Masdar invests in and develops projects, and it also issues debt. A person buying its corporate bonds is taking exposure to the issuer under the bond terms. The project’s avoided emissions and the bondholder’s financial outcome are different measures. Masdar’s investor disclosures, S&P Global’s published interview with Niall Hannigan

Start with the asset and the money

Masdar’s project factsheet identifies Al Dhafra as a solar photovoltaic independent power project developed by a consortium. It says Masdar owns 20%, TAQA owns 40% and the remaining share is split between two partners. It dates financial close to December 2020 and full operation to June 2023 and identifies Emirates Water and Electricity Company as the buyer of the plant’s power. That establishes a UAE asset, an ownership interest and a route for the electricity to be sold. It gives no private financial model or realised return for any shareholder. Masdar’s Al Dhafra project factsheet

Masdar’s June 2023 Instagram reel shows how the company presents its broader renewable-energy work.

The reel gives context about the company’s public communications. The allocation report does the accounting work. It shows the approximately US$38 million for Al Dhafra split across two 2024 bond tranches and lists no new allocation to the project in 2025. The fact that the asset was already operational before those bonds were issued matters when reading the word impact. The allocation records a financing relationship. A reader who wants to know whether that financing caused the project to be built would need separate evidence about what would have happened without it.

The project factsheet calls Al Dhafra a 2 GW plant. The 2025 finance report shows 1,640 MW in its table of contracted capacity and says in the methodology that nominal capacity is used in its calculations where capacity is an input. Those are different reporting labels. The figures should remain attached to their definitions unless the reader has evidence that translates one basis into the other. Neither is the same as electricity generated over a year, which the report expresses in gigawatt-hours.

Estimate the emissions the generation displaces

Masdar’s report describes multiplying annual energy generation by a baseline emissions factor for the electricity that the project is assumed to displace. Its appendix describes using a country-specific factor for intermittent generation. Al Dhafra’s row gives 4,651 GWh of annual generation and a displayed factor of 464 grams of carbon dioxide per kilowatt-hour. Multiplying the rounded inputs produces about 2.16 million tonnes of carbon dioxide for the project, consistent with the reported order of magnitude. Use the report’s figure for the exact published total. The values shown in the table are rounded, so they need not reproduce its last digits.

This calculation answers a question about an alternative. How much carbon dioxide would the assumed electricity mix have produced to supply the same generation? The factor is an assumption about the baseline. A meter can measure energy supplied, but it cannot measure the emissions of a scenario that did not happen. If the baseline changes, the estimate can change even if the plant delivers the same amount of electricity. This is one reason a reader should record the version of the factor alongside the number.

The 2025 report says its approach uses actual capacity and generation once a project has operated throughout the reporting period, and estimated data otherwise. A separate table footnote labels annual generation as a P50 yield assessment, a central estimate from a generation model. Those descriptions are enough to understand the method and the reported row, but they do not establish that the 4,651 GWh is an independently verified meter reading for 2025. The careful description is the annual generation input shown in the report. A reader who needs a historical output figure should seek a source that explicitly labels it as actual generation for the period.

Attribute only a share to the bonds

The report then assigns a share of the estimated project outcome to the bonds. The appendix starts with Masdar’s ownership share and applies financing terms that relate green bond proceeds and equity paid into the project. For Al Dhafra, the project table shows about 431,800 tonnes per year attributable to the bonds, roughly one fifth of its reported whole-project estimate. That arithmetic is consistent with the disclosed 20% ownership and the row’s stated financing basis. It does not mean that bondholders own one fifth of the plant or receive one fifth of the project’s cash flow.

Masdar says it changed the methodology in the 2025 report. Its prior approach compared bond proceeds allocated with estimated total equity commitment. The revised appendix describes using actual paid-in equity at the reporting date and adjusting for the relationship between estimated commitment and paid-in equity. The practical implication is that the attributed result can move when the financing basis changes, even if the project’s generation estimate stays constant. A comparison across years should therefore identify both the measurement year and the method used in each report.

An illustrative example makes the distinction easier to see. Suppose two reports both start from 100,000 tonnes of estimated annual project-wide avoided emissions and an investor’s ownership share is 20%. The ownership share of the estimate is 20,000 tonnes before any funding adjustment. If the attribution method assigns half of that share to the relevant financing, the reported financing impact is 10,000 tonnes. If the financing share changes to three quarters, the attributed amount rises to 15,000 tonnes. The physical estimate remained 100,000 tonnes in both cases. Those numbers illustrate the logic and do not reproduce a Masdar project calculation.

The same distinction applies when a report turns the attributed total into an intensity per dollar of financing. The numerator is the estimated annual impact allocated to the bonds. The denominator is a financial amount. A change in which projects receive the proceeds can move the ratio, as can a change in the emissions factors or the attribution method. Khan highlights a higher portfolio-level intensity in the 2025 foreword. Because the report also explains a methodological change, the reported progression alone cannot isolate how much improvement came from directing more money to higher-impact assets.

An investment team can make the comparison easier to audit by keeping a short reconciliation. Start with the prior figure, identify projects added or removed and then apply any revised generation or grid assumptions. Finally, show the effect of changing how the total is attributed. If the records cannot support each step, state which effects remain combined. That gives the reader a way to see whether the decision being discussed is about project selection, operating performance or accounting for the financing.

Read assurance and financial return separately

The 2025 report includes Ernst & Young’s limited assurance conclusion over selected metrics marked in the report. The assurance statement defines its subject matter by those marked items and the criteria applied to them. This can add confidence in the preparation of the specified figures under that method. It does not turn a baseline into an observed counterfactual or extend the conclusion to every claim in the document. A reader should check whether the exact line being cited carries the assurance mark and then read what the assurance report covers.

A financial review needs a different record. A corporate bond coupon gives a contractual rate applied to principal under its terms. What a particular investor earns also depends on the price paid, the timing of cash flows and whether the bond is held or sold. Project equity economics require a separate view of costs, power revenues, financing and distributions. The Al Dhafra allocation and impact figures do not supply those project cash flows. Khan’s foreword links capital allocation to estimated impact. It leaves the reader to use the appropriate evidence when assessing financial performance.

This separation becomes particularly important when comparing projects. One asset may show more estimated avoided emissions per dollar because its baseline is more emissions-intensive. Another may use a different ownership or attribution basis, or be earlier in construction. A commercial assessment can consider how predictable cash flows are and what risks the company must carry. An impact assessment can consider the expected generation and the counterfactual. Put the two views beside each other and explain why any comparison uses the same period and boundary.

A final question is what a project-level metric leaves outside its scope. Avoided electricity emissions do not describe every environmental or social effect of constructing and operating an asset. Masdar’s report describes screening environmental and social risks as part of its investment process. A reader assessing a specific effect, such as construction impacts or land use, would need a source that measures that effect. The avoided-emissions figure can be relevant to the decision without standing in for the rest of the assessment.

The Al Dhafra case is useful because it shows where each part of the claim can be checked. The project factsheet establishes the asset and Masdar’s role. The finance report traces allocations and explains its calculation. The assurance statement defines the extent of independent review. Readers can use those records to assess how Masdar reports a climate outcome alongside financing. Establishing the return on the project or on an individual bond purchase calls for financial evidence of its own.
