The capital behind the transition: How corporate green capex plans stack up against labeled bond issuance

Companies looking to advance their climate transitions have disclosed more than $7 trillion in spent and planned green capital expenditure, but relatively few of them have issued labeled debt to finance those efforts.

Highlights

Linking green and transition capital expenditure with labeled bond issuance reveals where corporate climate transition ambitions are accompanied by labeled financing and where capex plans have not yet been matched up with financing.

The Green and Transition CapEx dataset from Arctal and Sustainable1 identifies about $7.2 trillion in green capex, including both spent and planned investment, across 6,633 companies. Yet labeled bond issuance at these companies to date totals only about $2.7 trillion. The difference identifies a substantial universe for financing analysis and engagement.

This gap varies sharply by sector and region. Energy, utilities, materials and industrials account for most of the mismatch, with labeled debt covering just 16% of current and future green capex disclosed by these companies.

Issuance of labeled debt is highest in Europe, narrowing the gap with green capex the most among regions. By contrast, large capex plans in Asia have relatively little financing behind them.

Tracking the capital behind the climate transition has been a challenge historically. Disclosure of green capital expenditure (capex) at companies with transition ambitions is fragmented and often opaque, with relevant information frequently buried in narratives rather than available in financial reporting. Using the Green and Transition CapEx dataset from Arctal and S&P Global Energy Horizons Sustainable1, we identified the companies, sectors and geographies putting green, transition and adaptation and resilience-related capex into action. In this analysis, we take this data one step further by showing where green capex is outpacing issuance of sustainable debt — a gap that companies and financial institutions may look to explore as this market evolves.

The Green and Transition CapEx dataset screens, collects and standardizes disclosed data across about 25,000 companies, representing more than 95% of global market capitalization. We align reporting periods, sectors, regions and currencies; trace data back to underlying disclosures; and apply rigorous quality and consistency controls. Comparability is core to this approach, as companies may disclose similar targets but deploy capital toward them in fundamentally different ways. The result is a consistent, company-level view of green capex, which we are also able to link to a company's labeled debt, emissions, net-zero targets, alignment with Paris Agreement goals and climate physical risk exposure using additional Sustainable1 datasets. 

At a high level, we can see the broad landscape for corporate green and transition capex, including amounts that have been invested to date as well as multiyear capex investment plans. We have identified about $7.2 trillion in invested and planned green capex across 6,633 companies. About 80% of this total comes from future capex pipelines that companies have disclosed.

In this analysis, we explore how companies’ green capex compares to how they access the sustainable debt market. While labeled bond issuance is just one of the ways companies finance their transition spending, green infrastructure buildouts typically feature heavy upfront costs and long time horizons, and companies with large green capex ambitions tend to rely more on long-term debt to finance it. But as we discuss below, many companies with ambitious green capex plans have yet to issue labeled bonds at scale.

Green capex in transition sectors

Below, we rank sectors by total disclosed green capex versus their labeled debt issuance (green, sustainability, sustainability-linked and transition bonds, excluding social bonds) since 2021. The sectors with the largest disclosed green capex are utilities, industrials, energy and materials — carbon-intense sectors that are critical to delivering the energy transition. Yet these sectors also show relatively low labeled debt issuance. With labeled debt issuance equivalent to just 16% of disclosed green capex in these sectors, the difference between disclosed investment and labeled debt issuance is substantial. Across sectors, disclosed green capex totals $7.2 trillion, but these companies’ labeled bond issuance to date totals about $2.7 trillion.

For example, across the industrials sector, green capex exceeds labeled bond issuance by more than $1.2 trillion, identifying a substantial universe for financing engagement. Labeled bond issuance is equivalent to only 18% of disclosed green capex across the sector. On an individual company level, disclosed green capex has a median of $25 million and an average of $1 billion. That difference reflects concentration at the top, where a small number of very large programs pull the average well above the typical company. Therefore, the scale of disclosed investment varies significantly across companies' climate transition and resilience ambitions, while actual financing needs require further company-level assessment.

Financial institutions are a notable exception and should be interpreted differently. For banks in particular, labeled bond issuance primarily supports eligible green lending to clients rather than the bank’s own green capex, although a portion of proceeds may still finance the decarbonization of its own operations, such as green buildings.

Investment intent is not yet investment delivered

The Green and Transition CapEx dataset includes forward-looking green capex plans and commitments as well as historical spending, which gives us a view into where investment may accelerate. Disclosed future green capex plans are about 4x larger for utilities and industrials companies than already invested green capex, for example. Comparing capex with labeled debt clarifies the relationship between investment plans and resilient infrastructure build-out. Labeled debt reporting is now to some extent common practice, thanks to frameworks such as the International Capital Markets Association’s labeled bond principles (though disclosure is still not universal, as we have found in recent research). For green capex, on the other hand, effectively no standardization or expectation of reporting exists, which is where comparable data adds value. 

While Europe leads in sustainable finance, Asia leads in green capex

On a regional basis, Europe has mainstreamed sustainable debt, while Asia leads on green capex disclosure. Asia has the largest volume of disclosed green capex but one of the lowest shares of labeled bond issuance relative to it, a pattern that likely reflects regional capital markets conditions. As previous S&P Global Energy Horizons research has shown, China by itself accounts for more than half of global solar additions, and spending on cleantech far outpaces investment in fossil fuels. Labeled bond issuance is still relatively small in the region compared with its capex ambitions, however. In Europe, where sustainable debt issuance is common, labeled bond issuance represents nearly 70% of disclosed green capex.

Green capex is only part of the full picture

Combining a suite of corporate climate transition information — green capex, labeled bonds, emissions trajectory, transition plans and climate financial risk exposure — provides a basis for prioritizing where to deploy financing, transfer risk or allocate capital.

Let’s look at an individual company as a concrete example to illustrate the distance between recent disclosed spending and longer-term investment ambitions. This company, an Asian energy firm, has disclosed multi-billion-dollar green capex plans over the next decade in renewable energy and related infrastructure, compared with recent green capex in the millions and a relatively small amount of labeled debt issuance. Additional datasets can be called on to provide a full picture:

Data from the Sustainable1 Net-Zero Commitments Tracker shows that the company has committed to achieving net-zero by 2050 across Scope 1, Scope 2, and all upstream and downstream Scope 3 categories. The company has also stated interim targets.
Using the Sustainable1 Trucost Paris Alignment dataset, we can identify that the company’s emissions trajectory on an enterprise level is indeed below a 2 degrees C pathway based on the greenhouse gas emissions per unit of value added (GEVA) methodology. The largest share of emissions is associated with Scope 3 Category 11 (use of products).
The annual S&P Global Corporate Sustainability Assessment (CSA) also contains information on the company’s climate risk management practices and governance.
Using the Sustainable1 Physical Risk dataset to assess the company’s climate physical risk exposure, we find there is projected financial impact on the company’s assets from significant exposure to hazards including water stress, wildfire landslide and pluvial flooding in the 2030s.

These additional datasets enable us to cross-reference the company’s disclosed multi-billion-dollar future capital deployment plan with actual resilient infrastructure investments and the extent to which these investments support the company’s targets or respond to relevant climate risks.

Detailed, company-level analysis such as this allows:

banks to originate, identifying financing patterns where disclosed green capex appears large compared to current labeled debt issuance;
insurers to assess underwriting exposure, using disclosed transition and resilience investments alongside risk and vulnerability metrics; and
investors to allocate, comparing stated commitments with actual capex deployment.

Our data shows that companies have disclosed more than $7 trillion in green capex, but labeled bond issuance at these companies is equivalent to about 40% of that amount. Indeed, about $3.5 trillion in green capex has been disclosed by companies without recorded any labeled bond issuance. These figures reveal the scale of green capex occurring outside the labeled bond market, not necessarily investment that is going unfunded. How are these companies financing their plans?

In future blogs in this series, we take a deeper dive into this $3.5 trillion whitespace and explore the companies that disclose both green capex and issue labeled bonds.
