The financed emissions generated through a financial institution's loans, investments, and underwriting activities often eclipse its direct operational footprint. Banks, asset managers, and insurers need to be able to accurately measure and manage these greenhouse gases, especially in the face of growing climate disclosure expectations. Financed emissions software greatly streamlines the process. The right platform will ensure reliable, traceable, and decision-useful calculations. Key features to look for include alignment with PCAF and other global frameworks, portfolio engagement tools, traceability, and advanced data security.
Financial institutions increasingly find themselves at the center of the global climate conversation, and for good reason. The emissions generated by the companies, projects, and assets they finance generate a substantial (and largely underreported) share of global greenhouse gases. These financed emissions can account for up to 700 times more than the emissions an institution produces directly.
Financed emissions also represent risk. Despite recent policy shifts, global expectations for climate disclosure have persisted. Without a solid understanding of their financed emissions, institutions can expose themselves to legal and reputational damage. The credit and market risks from climate change are also growing. Institutions must now consider how climate factors might lead to stranded assets, devaluation, borrowers defaulting on loans, and other scenarios. The potential toll of these climate-related risks is not small—it could add up to more than $1T USD, according to research by the CDP.
To manage these risks, institutions first need a clear picture of their financed emissions. A growing market of specialized software has emerged to help banks, asset managers, insurance companies, and private equity firms quantify emissions, comply with emerging regulations, and decarbonize efficiently.
This guide provides an overview of what financed emissions software is, the features that matter most, and the platforms leading the market in 2026.
What is financed emissions software?
Specialized carbon accounting software measures a financial institution’s indirect scope 3 emissions.
Financed emissions software enables institutions to measure, manage, and disclose the greenhouse gases associated with their lending, investment, and underwriting activities.
These indirect emissions fall under Scope 3, Category 15 of the Greenhouse Gas Protocol, and they require a fundamentally different accounting methodology than direct scope 1 and 2 emissions. Rather than simply tracking emissions from electricity consumption or fuel usage, organizations must attribute a proportional share of a counterparty's emissions to their own balance sheet, weighted by the size of their financial exposure.
The leading framework for calculating financed emissions comes from the Partnership for Carbon Accounting Financials (PCAF) Global GHG Accounting and Reporting Standard, Part A (“PCAF Standard”). Financed emissions software that is fit for purpose will be built on PCAF's methodology and cover its full range of asset classes, including listed equity and bonds, business loans, mortgages, motor vehicle loans, commercial real estate, project finance, sovereign debt, sub-sovereign debt, UoP structures, securitizations, and structured products.
Why do financial institutions need dedicated carbon accounting software?
Calculating financed emissions is complex.
Measuring financed emissions can be resource-intensive and complex. It requires institutions to collect disaggregated data from portfolio companies, apply the correct methodology across asset classes, and align with the appropriate (and up-to-date) regulations and frameworks.
Challenges in calculating financed emissions
Data complexity and availability. To calculate financed emissions, you have to combine portfolio data (e.g., ownership stakes or outstanding balances) with emissions data (scope 1, 2, and sometimes 3) for each investee company. This data can be difficult to gather—it often comes from disparate sources, including financial systems, third-party data providers, and company disclosures, with widely ranging levels of quality and completeness.
Differences across asset classes. PCAF defines distinct methodologies for each asset class, and a large institution may hold dozens of asset types across thousands of companies. Applying the correct methodology consistently, at scale, is a substantial technical challenge.
Regulatory alignment. Despite recent rollbacks, climate disclosure regulations continue to advance around the world. These include Europe’s Corporate Sustainability Reporting Directive (CSRD), California’s SB 253, and ISSB-aligned policies in dozens of other jurisdictions. Institutions without a credible methodology and auditable data expose themselves to regulatory (and reputational) risk.
Features to look for in financed emissions software
Platforms should offer a few essential capabilities.
Different carbon accounting tools are suited for different purposes. If you’re looking for a platform specifically to measure financed emissions, there are a few essential features to keep in mind. These include:
PCAF-Aligned Methodology
The foundation of any credible financed emissions platform is adherence to the PCAF Global GHG Accounting and Reporting Standard. Choose a platform that applies PCAF's asset-class-specific methodologies accurately and transparently, with clear documentation of how attribution factors and emission intensities are derived.
Portfolio Engagement
Gathering data from portfolio companies is often one of the most resource-intensive steps in the carbon accounting process. Look for software that supports portfolio engagement: Many borrowers and investees will need help calculating their emissions before they can share data with you, and you want to ensure this data is consistent and comparable.
Advanced Analytics
Calculating financed emissions is only valuable if it helps inform your decision-making. The best platforms will go beyond measurement and provide portfolio-level analytics that allow you to pinpoint heavy emitters, model different scenarios, and quantify the emissions impact of investment decisions.
Traceability and Visibility
As third-party assurance of financed emissions disclosures becomes more common, you need to be able to track calculations all the way from raw inputs to the final figures you report. Look for software with the same rigor as financial ledgers, where every data point is traceable and defensible. You should retain full visibility and control over your data throughout the process, so you can easily see the methodology, data, and emission factors that were used to arrive at your estimate.
Global Alignment
Climate and sustainability regulations are rapidly changing. Platforms with dedicated regulatory monitoring and update cycles will lead to greater consistency, comparability, and efficiency. In addition to PCAF, your software should align with frameworks like CDP, ISSB, and TCFD, as well as major regulations like Europe’s CSRD and California’s SB 253 and SB 261.
Data Security
The data that flows through a carbon accounting platform is sensitive by nature. It can include portfolio compositions, counterparty information, financial exposures, proprietary investment details, and more. The use of AI introduces new liabilities and further raises the stakes. This makes software selection a critical security decision. The most trustworthy providers will be able to show how they protect your information. Look for platforms with SOC 2 Type II certification—the gold standard for data security.
The Best Financed Emissions Software in 2026
Sustainability rules are a moving target. Regulatory shifts, emerging technology, and market volatility continue to reshape disclosure requirements and expectations. As they do, carbon accounting software is evolving. To help you keep up, here’s our current breakdown of the top financed emissions software in 2026 (in no particular order):
Pulsora
Pulsora is an all-in-one enterprise sustainability management platform designed to streamline ESG data collection, measurement, reporting, and analysis. It allows teams to explore emissions data at a granular level, from location-based specifics to individual facilities or buildings.
Pulsora provides flexibility in calculation methods, emission factors, intensity factors, and other key parameters.
