Climative and TD Bank Group Explore Novel Approaches to Improve Financed Emissions Reporting in Canada

As financial institutions face increasing regulatory pressures and stakeholder expectations to measure, disclose, and reduce their financed emissions, the need for accurate, scalable, and cost-effective carbon reporting solutions has become critical. TD Bank Group worked with Climative to test a novel approach (described in a white paper) for improving financed emissions data quality in residential portfolios.

The pilot demonstrated how Climative’s Automated Climate Model (ACMTM) empowers financial institutions to achieve a PCAF Data Quality Score (DQS) of 3 or higher for reporting carbon emissions on their financed emissions portfolio at scale. Climative is now a Regional Accredited Partner of PCAF.

Good to Know:

PCAF is the Partnership for Carbon Accounting Financials, the framework that financial institutions use to measure and disclose financed emissions in accordance with OSFI Guideline B-15.

Data Quality Score (DQS) ranges from 1 (highest data quality) to 5 (lowest data quality).

The Challenges

The white paper discusses the challenges financial institutions are facing in measuring and reporting their financed emissions footprint and setting carbon reduction targets, including:

  1. Data gaps due to limited access to building-specific information, such as living area, energy source, and insulation details.
  2. Reliance on low data quality carbon scores (DQS 4 or 5) based on regional averages, which can lead to understating financed emissions and limit the ability to set and monitor actionable reduction targets.
  3. Scalability and cost constraints associated with achieving DQS 3 or above, which requires data and detailed analysis at the individual property level.

Climative's Approach

Climative’s ACM leverages machine learning algorithms, historical energy audit results, property-level building characteristics data, weather data, and region-specific emission factors to develop a robust framework for measuring and tracking financed emissions. This approach not only addresses key challenges in data quality, scalability, and regulatory compliance but also provides actionable climate risk and carbon emission reduction roadmaps for financial institutions and individual homeowners.

The Results

Key findings from the pilot project evaluating Climative’s carbon assessment framework include:

  1. PCAF DQS 3 compliance: The study confirmed that Climative uses property-level building characteristics to create energy labels and estimate carbon emissions, while training its model on actual energy assessment data from EnerGuide, meeting PCAF DQS 3 requirements. PCAF alignment is a
  2. Improved data quality: The ACM achieved a weighted average PCAF data quality score of 3 for the BC provincial inventory, a significant improvement from the previous DQS of 4 or 5 using regional averages.
  3. Strong alignment with EnerGuide assessments: The ACM output demonstrated high correlation with historical onsite EnerGuide assessments (Canada’s official energy labels), showing a Mean Percentage Error of 1% and a Mean Absolute Percentage Error of 14%.
  4. Enhanced Scalability and Cost-Effectiveness: The ACM’s automated approach enabled instant assessment of entire portfolios, offering an efficient and cost-effective solution.
  5. Delivery of Actionable insights: The property-level data facilitated the identification of properties in climate risk zones, high-emission properties and potential retrofit opportunities, supporting financial institutions in creating actionable protection and decarbonization roadmaps in response to regulatory requirements.

The Impact for Financial Institutions

By adopting the ACMTM and partnering with Climative, financial institutions can enhance the data quality of their emissions reporting, set more meaningful decarbonization targets, and craft impactful strategies for addressing climate-related risks and opportunities in their mortgage portfolios.
