In the fight against climate change, the financial sector plays a pivotal role in reducing global carbon emissions. While banks may not produce significant direct emissions, their indirect impact through financed activities is immense. These “financed emissions” arise from the loans and investments banks make in industries like energy, transportation, and real estate, which are often major contributors to carbon footprints. In fact, a recent study found that financed emissions of global banks are 700 times greater than their direct operational emissions, highlighting the importance of addressing this issue at its core. [3] 

Banks have a unique responsibility to help steer capital towards low-carbon solutions and sustainable businesses. This is where the Partnership for Carbon Accounting Financials (PCAF) comes into play. PCAF provides a standardized methodology that helps banks measure and disclose the carbon footprint of their lending and investment portfolios, enabling them to take actionable steps in reducing emissions. 

In this article, we’ll explore the importance of carbon footprint calculation for banks using the PCAF methodology. You’ll learn the key concepts, calculation steps, and benefits of adopting PCAF standards, as well as insights from real-world examples of banks leading the way in climate responsibility. 

What is PCAF? 

The Partnership for Carbon Accounting Financials (PCAF) was established in 2015 by a group of Dutch financial institutions committed to addressing the impact of their investments on climate change. Initially a regional initiative, PCAF has grown into a global partnership, with over 400 financial institutions from all continents now participating. The initiative’s primary objective is to provide a standardized methodology that allows financial institutions to measure and disclose the greenhouse gas (GHG) emissions associated with their loans and investments—commonly referred to as financed emissions. 

PCAF’s framework is designed to help financial institutions assess their climate impact in a transparent and consistent way. Key stakeholders in PCAF include banks, asset managers, pension funds, and insurance companies. These institutions use PCAF’s guidelines to improve their carbon accounting practices, aligning their portfolios with global sustainability goals. [1] 

In supporting climate action, PCAF enables financial institutions to track and reduce their financed emissions, contributing to the broader objectives of limiting global warming. PCAF’s methodology aligns with other prominent frameworks, such as the Task Force on Climate-related Financial Disclosures (TCFD) and the Science-Based Targets initiative (SBTi), ensuring that the financial sector can meet both regulatory and voluntary sustainability commitments while driving meaningful change in the global economy. 

Key Concepts in PCAF Carbon Footprint Calculation 

Financed Emissions Explained 

Financed emissions refer to the greenhouse gas (GHG) emissions associated with the loans, investments, and financial activities of institutions like banks. Unlike direct emissions, which come from a bank’s internal operations (e.g., energy use, transportation), financed emissions arise from the activities of the companies and projects a bank finances. For example, when a bank lends money to a company in the energy sector, the emissions produced by that company’s operations are considered part of the bank’s financed emissions. Tracking these emissions is essential because they often make up the largest part of a bank’s total carbon footprint. By measuring and managing financed emissions, banks can reduce their indirect impact on climate change. 

Scopes of Emissions 

Emissions are categorized into three Scopes based on their source: 

• Scope 1: Direct emissions from owned or controlled sources (e.g., company vehicles). 

• Scope 2: Indirect emissions from purchased energy (e.g., electricity). 

• Scope 3: All other indirect emissions, including financed emissions. For banks, PCAF focuses on Scope 3, as it encompasses emissions from lending and investment activities, making it the most relevant scope for carbon accounting in the financial sector. [2] 

PCAF’s Emissions Attribution Approach 

PCAF’s methodology attributes emissions to banks based on their share of financing in a particular company or project. For instance, if a bank provides 40% of the financing for a business, it would account for 40% of that company’s emissions in its carbon footprint. This approach ensures that emissions are accurately reflected in proportion to a bank’s financial involvement, allowing for more precise measurement and reporting. 

The PCAF Methodology for Banks 

Data Collection and Quality Standards 

Accurate data collection is the foundation of PCAF’s carbon footprint calculation. Banks need to gather detailed loan data (e.g., the amount lent, duration, and purpose of loans) and borrower emissions data, such as greenhouse gas (GHG) emissions reported by companies. If borrower-specific emissions data isn’t available, banks can use sector averages or estimates based on financial metrics like revenue or asset size. PCAF assigns a data quality score ranging from 1 (best) to 5 (worst), which reflects the accuracy and reliability of the data used. A higher-quality score means more accurate emissions reporting, ensuring better decision-making for managing carbon footprints. 

Sector-Specific Calculation Approaches 

PCAF tailors its methodology to account for the unique characteristics of various sectors. For instance: 

• Real Estate: Emissions are calculated based on energy consumption data from buildings or real estate assets, often using data such as square footage and energy intensity. 

• Agriculture: Emissions are based on land use, livestock, and production inputs, accounting for the environmental impact of agricultural activities. 

• Energy: Emissions from energy companies are calculated using data on fuel production, energy output, and emissions factors. These sector-specific approaches ensure that banks can accurately calculate the carbon footprints of diverse portfolios, reflecting the varying emissions intensity of different industries. 

Steps for Banks to Implement PCAF 

Step 1: Assessing Portfolio Coverage 

The first step for banks is to evaluate their lending and investment portfolio to understand the extent of their financed emissions. This involves reviewing all asset classes, loans, and investments to determine which sectors are most carbon-intensive. Sectors such as energy, real estate, agriculture, and manufacturing often have high carbon exposure. By identifying these high-risk sectors, banks can prioritize their carbon accounting efforts, focusing on areas where their financing has the most significant environmental impact. 

Step 2: Collecting and Assessing Data 

Banks must then gather borrower-level emissions data and relevant financial data. Borrowers may provide direct emissions data, such as annual GHG reports. When direct data is unavailable, banks can use industry averages or proxies based on sector-specific emissions factors. One of the key challenges in this step is the availability and accuracy of data. To overcome these challenges, banks can use third-party databases or emissions estimates while prioritizing data quality (using PCAF’s data quality score). Close collaboration with borrowers and sector-specific benchmarks helps ensure data reliability and improve emissions tracking. 

Step 3: Calculating Emissions 

Once data is collected, banks can apply the PCAF methodology to calculate their financed emissions. This involves attributing a portion of a borrower’s emissions to the bank based on the bank’s share of financing. Available tools and software, such as carbon accounting platforms, help banks automate this process and ensure calculations are consistent with PCAF’s standards. These tools also enable the inclusion of various emission scopes, making the calculation process efficient and scalable across portfolios. 

Step 4: Reporting and Disclosing Emissions 

After calculating emissions, banks must report their findings in alignment with PCAF and other sustainability frameworks, such as the Task Force on Climate-related Financial Disclosures (TCFD). Regular, transparent disclosure of financed emissions is crucial for maintaining stakeholder trust and meeting regulatory requirements. Banks should present emissions data in sustainability reports and ensure that it is updated annually to reflect changes in the portfolio. Clear communication of these results shows a bank’s commitment to climate action and enhances its reputation in the financial community. 

Case Studies: Banks Successfully Using PCAF 

Case Study 1: European Bank Example 

ABN AMRO, a leading European bank based in the Netherlands, was one of the early adopters of the PCAF methodology. In line with its commitment to climate responsibility, the bank began calculating and disclosing its financed emissions in 2017. ABN AMRO implemented the PCAF framework across various sectors, including real estate, where they focused on energy efficiency improvements. Through data collection and collaboration with clients, ABN AMRO encouraged property owners to adopt low-carbon technologies. The bank also improved the quality of data used in their emissions calculations by integrating borrower-specific emissions data wherever possible. 

As a result, ABN AMRO managed to reduce its financed emissions by 20% over a five-year period. This was achieved through a combination of active engagement with high-carbon sectors, better data quality, and the redirection of capital toward sustainable projects. The bank’s transparency in reporting also earned them recognition in sustainability circles, further enhancing their reputation for environmental leadership. 

Case Study 2: US Bank Example 

In the United States, Bank of America embraced the PCAF methodology as part of its broader sustainability and climate initiatives. The bank started by assessing the carbon exposure of its lending portfolio, particularly in high-emission sectors such as energy and transportation. Through PCAF’s sector-specific approaches, Bank of America was able to quantify financed emissions and identify areas for improvement. 

One of the key steps the bank took was engaging with clients in high-emission sectors, providing incentives for businesses to transition toward renewable energy and more efficient operations. Bank of America also invested in data collection systems, using advanced tools to enhance the accuracy of emissions calculations. 

By leveraging the PCAF framework, Bank of America significantly improved its carbon accounting practices. This led to more precise emissions reporting and helped the bank set realistic, science-based targets for reducing its financed emissions. The improvements not only supported the bank’s climate goals but also strengthened relationships with stakeholders and clients, showcasing the benefits of responsible finance in a rapidly changing regulatory landscape. 

Conclusion 

The adoption of PCAF’s carbon footprint calculation methodology is a crucial step for banks in aligning their operations with global sustainability goals. By understanding and managing financed emissions, banks can not only mitigate climate risks but also enhance their role in fostering a low-carbon economy. The PCAF framework offers a structured and comprehensive approach to quantifying these emissions, empowering financial institutions to make data-driven decisions that benefit both their business and the planet. 

As climate change increasingly shapes the regulatory landscape and investor expectations, banks that proactively embrace carbon accounting will be better positioned to manage risks and seize opportunities in sustainable finance. By committing to transparent reporting and continuously refining their emissions data, banks can strengthen stakeholder trust and contribute meaningfully to the global transition toward a more sustainable future. 

Now is the time for financial institutions to adopt PCAF’s methodology, take ownership of their environmental impact, and lead the way toward a greener financial system.
