GARP SCR Chapter 10 Formulas: How to Recognize Which Formula the Question Is Testing
Chapter 10, Transition Planning and Carbon Reporting, is one of the areas where GARP SCR candidates can encounter calculations. The good news is that the SCR Exam is not highly quantitative. GARP says candidates should expect only limited multiplication and division, ratios, units, tables, and quantitative information rather than advanced mathematics. The 2026 exam contains 80 equally weighted multiple-choice questions over four hours.
For Chapter 10, the challenge is therefore less about difficult mathematics and more about recognizing what the question is asking you to calculate.
Formula 1: Calculating GHG Emissions
The 2026 learning objectives require candidates to calculate greenhouse gas emissions using activity data, conversion or emission factors, and global warming potential (GWP). The core relationship is:
GHG Emissions in CO₂e = Activity Data × Emission Factor × GWP
Your FutureGreenWorld 2026 fact sheet specifically connects this calculation to Scope 1, Scope 2, and Scope 3 emissions.
The current GHG Protocol also describes the same calculation methodology: activity data is multiplied by an emission factor and, where required, GWP to express different greenhouse gases in CO₂-equivalent terms.
How do you recognize this question?
Look for phrases such as:
fuel consumed, electricity used, kilometres travelled, tonnes of material, emission factor, kg CH₄, GWP, or calculate CO₂e.
For example, suppose a company produces 100 kg of methane emissions, and the question provides a GWP of 29.
CO₂e = 100 × 29 = 2,900 kg CO₂e
The clue is the presence of a greenhouse gas other than CO₂ plus a GWP. The question wants you to convert that greenhouse gas into CO₂-equivalent emissions.
First identify the correct Scope
Before calculating anything, determine which emissions category is being tested.
Scope 1 covers direct emissions from owned or controlled sources, such as fuel burned in company vehicles or boilers.
Scope 2 covers emissions associated with purchased electricity, steam, heating, or cooling.
Scope 3 covers other indirect value-chain emissions, such as business travel, purchased goods, waste, and financed emissions.
A calculation may therefore be mathematically simple but conceptually difficult because GARP can test whether you selected the correct activity data and emissions scope.
Formula 2: Attribution Factor
Financial institutions need another calculation because they usually finance only part of a company or project.
The Chapter 10 fact sheet gives:
Attribution Factor = Outstanding Amount ÷ (Total Equity + Debt)
The learning objective is to understand what portion of a borrower's or investee's emissions should be attributed to the financial institution.
Suppose a bank has a $20 million outstanding loan to a company with $100 million of total equity and debt.
Attribution Factor = 20 ÷ 100 = 20%
Recognition clue
If the question gives you:
outstanding investment or loan + company financing/value + emissions
you should immediately think:
Attribution factor first. Financed emissions second.
Formula 3: Financed Emissions
Once the attribution factor is known:
Financed Emissions = Attribution Factor × Borrower/Investee Emissions
For a portfolio:
Total Financed Emissions = Σ (Attribution Factorᵢ × Emissionsᵢ)
This is explicitly part of the Chapter 10 learning objectives.
Using the previous example, assume the borrower generates 50,000 tCO₂e.
Financed Emissions = 20% × 50,000 = 10,000 tCO₂e
The bank therefore attributes 10,000 tCO₂e to its financing activity. GARP SCR Chapter 10 Formulas
One important 2026 study note: the current PCAF methodology uses asset-class-specific attribution denominators. The simple Total Equity + Debt relationship is particularly relevant to business-loan/unlisted-equity style calculations; candidates should not assume every real-world asset class uses exactly the same denominator. PCAF's latest standard continues to apply the basic principle of attributing emissions according to the financial institution's proportional financing share.
The fastest way to identify the formula GARP SCR Chapter 10 Formulas
On exam day, classify the information before touching your calculator:
If the question gives you… | Think… |
Activity + emission factor | GHG emissions |
Non-CO₂ gas + GWP | Convert to CO₂e |
Outstanding financing + company value | Attribution factor |
Attribution factor + company emissions | Financed emissions |
Several borrowers/investees | Sum financed emissions |
Chapter 10 is therefore not about memorizing dozens of equations. It is about recognizing which stage of the carbon-accounting process the question is testing.
A useful sequence to memorize is:
Activity → Emissions → CO₂e → Attribution → Financed Emissions
If you can identify where a question sits in that chain, most Chapter 10 numerical problems become much easier.
