How the numbers are calculated

See the exact logic behind the dashboard.

This tab explains where each dashboard number comes from. It keeps live stock prices separate from annual emissions data so users know what is changing in real time and what is based on company disclosures.

Live input
Stock price
Used to update portfolio value and weights.
Annual input
Emissions
Latest available Scope 1 and Scope 2 data.
Main output
Financed tonnes

01

Portfolio value = quantity x live stock price

If the user owns 50 shares and the live price is Rs 1,000, that holding is worth Rs 50,000. When the stock price changes, the holding value and portfolio weight also change.

Example50 shares x Rs 1,000 = Rs 50,000 holding value. If the price rises to Rs 1,100, the holding becomes Rs 55,000.
  1. Fetch live price from the quote API.
  2. Multiply by quantity.
  3. Add all holdings to get total portfolio value.
  4. Divide each holding value by total value to get its weight.

Live prices change portfolio weights, and weights change carbon exposure.

02

Financed emissions = your share of a company's emissions

The model estimates your share by dividing holding value by enterprise value, then multiplying by the company's Scope 1 and Scope 2 emissions.

ExampleIf holding value is Rs 1 lakh and enterprise value is Rs 10,000 crore, the attribution share is tiny. That tiny share is multiplied by company emissions.
  1. Calculate holding value.
  2. Divide by enterprise value.
  3. Multiply by Scope 1 + Scope 2 emissions.
  4. The result is financed emissions in tonnes.

This is an educational PCAF-style approximation, not a certified audit.

03

Carbon cost shows a possible future liability

If the portfolio is linked to 10 tonnes of emissions and the carbon price scenario is Rs 2,600 per tonne, the possible carbon cost is Rs 26,000.

Example10 tCO2e x Rs 2,600 = Rs 26,000. If emissions rise to 20 tonnes, the same scenario becomes Rs 52,000.
  1. Take financed emissions from the dashboard.
  2. Choose a carbon price scenario.
  3. Multiply tonnes by price.
  4. Use the result as a stress-test number.

Carbon cost is not today's bill. It is a scenario to understand possible future risk.

04

CBAM exposure shows which holdings may face export carbon rules

The site labels sectors like steel and cement as CBAM-covered, and textiles as a watchlist scenario. It then calculates how much current portfolio value sits in those categories.

ExampleIf Rs 2 lakh of portfolio value is in steel and cement, and total value is Rs 10 lakh, then 20% of the portfolio is in CBAM-covered sectors.
  1. Label each company by policy exposure.
  2. Use live prices to calculate current holding values.
  3. Add values in covered and watchlist sectors.
  4. Show the share as a percentage of portfolio value.

CBAM exposure is a policy-risk indicator, not a guarantee of future cost.
