ESG Carbon Metrics: tCO₂e
This article explains how Wiserfunding expresses ESG Carbon Metrics using tCO₂e
Carbon intensity measures the amount of greenhouse gas emissions generated relative to economic activity.
At Wiserfunding, carbon intensity is expressed as:
Tonnes of CO₂ equivalent (tCO₂e) per £1,000 of turnover
This allows companies of different sizes to be compared on a consistent basis.
For example:
- Company A emits 100 tonnes of CO₂e and generates £1 million of turnover.
- Company B emits 10,000 tonnes of CO₂e and generates £100 million of turnover.
Although Company B emits more in absolute terms, both companies have the same carbon intensity.
tCO₂e
tCO₂e stands for tonnes of carbon dioxide equivalent.
Greenhouse gas emissions include several gases, such as:
- Carbon dioxide (CO₂)
- Methane (CH₄)
- Nitrous oxide (N₂O)
Because each gas contributes differently to global warming, emissions are converted into a common unit called CO₂ equivalent (CO₂e). This allows all greenhouse gases to be measured and compared using a single metric.
