Institutional investors managing more than $9 trillion in assets are tightening the way they measure and report climate risks within their investment portfolios.
The Net-Zero Asset Owner Alliance (NZAOA) has released the fifth version of its Target-Setting Protocol, a key framework that guides how asset owners align their investment portfolios with the goal of net-zero greenhouse-gas emissions by 2050.
The updated protocol introduces a new category of transition targets, designed to help investors track and support companies that are actively moving toward low-carbon business models.
Rather than focusing exclusively on reducing portfolio emissions, the revised framework places stronger emphasis on how investors support real-economy decarbonisation, particularly in sectors that currently produce high levels of emissions.
The new approach reflects a growing understanding within financial markets that achieving net zero requires not only reducing emissions within investment portfolios but also directing capital toward companies transforming their operations.
Markets move fast; don’t get left behind. We’ve paired the Serrari Group Market Index with a curated Marketplace and a comprehensive Financial Literacy Course to ensure you have the data—and the skills—to act on it.
A $9 Trillion Investor Coalition Driving Climate Alignment
Founded in 2019 under the United Nations Environment Programme Finance Initiative, the Net-Zero Asset Owner Alliance brings together institutional investors committed to aligning their portfolios with the Paris Agreement’s climate goals.
The alliance has expanded rapidly in recent years and now includes 87 signatories across 19 countries, representing pension funds, insurance companies and sovereign wealth funds.
Collectively, these investors manage more than $9 trillion in assets, giving the alliance significant influence over how global capital markets respond to climate risk.
Members commit to setting intermediate climate targets in five-year cycles while progressively aligning their investment strategies with net-zero emissions by mid-century.
The Target-Setting Protocol serves as the alliance’s main guidance document for how investors measure progress toward these commitments.
With the release of its fifth version, known as TSP5, the framework evolves to address emerging challenges in climate reporting and transition finance.
Shift From Portfolio Emissions to Real-Economy Transition
One of the most notable changes in the updated protocol is a shift away from focusing solely on portfolio-level emissions metrics.
While measuring financed emissions remains important, the alliance now emphasizes the need for investors to support companies that are actively transitioning toward low-carbon business models.
This change reflects a key challenge in climate finance: many of the industries responsible for the largest share of global emissions—such as heavy industry, transportation and energy—remain essential to the global economy.
Rather than divesting entirely from these sectors, investors increasingly aim to finance their transformation.
The updated protocol therefore encourages asset owners to demonstrate how their capital supports companies that are implementing credible decarbonisation strategies.
By doing so, the alliance hopes to move climate investment beyond portfolio optics and toward measurable emissions reductions in the real economy.
New Transition Targets for High-Emitting Sectors
The introduction of transition targets represents the most significant structural addition to the framework.
These targets measure the share of portfolio emissions associated with “transitioning assets.”
Transitioning assets generally refer to companies operating in high-emitting sectors that have credible strategies in place to reduce emissions and align with net-zero pathways.
Instead of encouraging investors to abandon these sectors entirely, the framework aims to support capital flows toward companies that are actively working to decarbonise.
To qualify as a transition asset, companies must meet a series of criteria that demonstrate their commitment to climate alignment.
These criteria include:
- Alignment with the Paris Agreement
- Adoption of science-based emissions targets
- Clear timelines for emissions reductions
- Integration of climate goals into corporate policies
- Transparent reporting on progress
By introducing these indicators, the alliance seeks to help investors differentiate between companies that are genuinely transitioning and those that rely on long-term pledges without meaningful operational changes.
Credible Transition Plans Become Central to Climate Reporting
The updated protocol also introduces clearer principles for evaluating whether corporate transition plans are credible.
Investors are expected to assess whether companies have established time-bound decarbonisation strategies that are integrated into their governance structures and operational planning.
For example, companies must demonstrate that climate targets influence capital expenditure decisions, business strategy and executive oversight.
The framework also examines whether corporate lobbying activities align with climate commitments.
Transparency is another critical element. Companies classified as transition assets must provide regular climate disclosures allowing investors to monitor progress.
These reporting requirements aim to strengthen the credibility of net-zero commitments while improving the quality of climate risk information available to financial markets.
A Revised Four-Part Target-Setting Framework
With the introduction of transition targets, the alliance’s target-setting structure now consists of four categories.
These include:
- Engagement Targets
- Sector or Transition Targets
- Climate Solutions Investment Targets
- Sub-portfolio Emissions Targets
Members of the alliance are required to set targets in at least three of these four categories.
However, engagement targets remain mandatory, reflecting the alliance’s view that investor engagement plays a critical role in accelerating corporate decarbonisation.
Under these targets, asset owners must actively engage with companies responsible for the largest share of their financed emissions.
Investors are required to engage with at least 20 high-emitting companies or companies representing 65% of emissions within their corporate equity and bond holdings.
The goal is to ensure that investor influence is directed toward the companies with the greatest potential to drive emissions reductions.

Quantifying Investment in Climate Solutions
Another key feature of the updated protocol is a stronger focus on climate solutions investments.
For the first time, the framework introduces quantitative targets requiring investors to track how much capital they allocate to technologies and infrastructure supporting the energy transition.
Examples of climate solutions include:
- Renewable energy infrastructure
- High-voltage transmission networks
- Electric battery manufacturing
- Smart grid technologies
- Climate-resilient agriculture
Investments in these sectors play a crucial role in supporting global decarbonisation efforts.
By requiring asset owners to track these investments more rigorously, the alliance aims to encourage greater capital flows toward technologies that enable the energy transition.
Integrating Carbon Removals Into Investor Strategies
The updated protocol also expands guidance on the role of carbon dioxide removal (CDR) in investor climate strategies.
Carbon removals refer to technologies or natural solutions that remove carbon dioxide from the atmosphere, including:
- Direct air capture technologies
- Reforestation projects
- Soil carbon sequestration
The alliance encourages signatories to help finance the development of high-integrity carbon removal markets.
However, the framework maintains strict safeguards to prevent over-reliance on these solutions.
The protocol states clearly that carbon removals cannot be used to meet portfolio emissions targets before 2030.
This restriction reflects concerns among investors and regulators that excessive reliance on carbon offsets could delay real emissions reductions.
Instead, the alliance emphasizes that direct decarbonisation must remain the primary strategy.
Strengthening Climate Risk Transparency
The revised framework arrives at a time when financial regulators and investors are placing increasing emphasis on climate risk disclosure and reporting standards.
Institutional investors face growing scrutiny from regulators, beneficiaries and the public regarding the credibility of their net-zero commitments.
Critics have argued that some climate pledges rely too heavily on portfolio metrics without demonstrating how capital allocation actually contributes to emissions reductions.
By introducing transition targets and strengthening reporting requirements, the alliance hopes to address these concerns.
The updated protocol encourages investors to link portfolio strategies directly to real-economy decarbonisation outcomes, improving transparency in climate risk reporting.
Implications for Global Capital Markets
Because the alliance’s members collectively manage trillions of dollars in assets, its frameworks often influence broader market practices across global financial markets. When major institutional investors adopt shared climate frameworks, their expectations can shape how other investors and companies approach climate risk and sustainability strategies.
The updated protocol could therefore influence how investors assess climate risk, transition pathways and portfolio alignment with net-zero goals. Many market participants look to initiatives like the Net-Zero Asset Owner Alliance for guidance on translating climate commitments into practical investment strategies.
For pension funds, insurance companies and sovereign wealth funds, the framework raises expectations around portfolio transparency, engagement strategies and the evaluation of credible transition plans.
It also highlights the growing importance of integrating climate considerations into long-term financial planning.
Companies seeking access to institutional capital may therefore face stronger expectations to demonstrate measurable progress toward decarbonisation and clear, credible transition strategies.
Outlook: Climate Reporting Moves Into a New Phase
The release of the Net-Zero Asset Owner Alliance’s updated protocol signals that climate finance is entering a new phase.
Rather than focusing primarily on reducing portfolio emissions, investors are increasingly seeking to drive real-world emissions reductions across key sectors of the global economy.
The introduction of transition targets reflects this shift.
For investors, the challenge now lies in identifying companies that are genuinely transforming their operations and allocating capital accordingly.
For corporations, the message is becoming clearer: credible, transparent and science-aligned transition plans are likely to become a key requirement for attracting long-term investment capital.
As regulatory scrutiny intensifies and climate risks become more prominent in financial markets, frameworks such as the NZAOA’s Target-Setting Protocol are likely to play an increasingly influential role in shaping the future of sustainable finance and climate reporting.
