1. What is the GWP Calculation?

The GWP (Global Warming Potential) calculation estimates the global warming impact of greenhouse gas emissions using UK-specific conversion factors. It provides a standardized way to compare the climate impacts of different greenhouse gases.

2. How Does the Calculator Work?

The calculator uses the GWP equation:

Where:

• \( Emission \) — Greenhouse gas emissions in kilograms (kg)
• \( UK Factor \) — UK-specific conversion factor (dimensionless)

Explanation: The equation multiplies the emission quantity by the UK-specific conversion factor to calculate the global warming potential in CO₂ equivalent units.

3. Importance of GWP Calculation

Details: Accurate GWP calculation is crucial for environmental reporting, carbon footprint assessment, climate change mitigation planning, and regulatory compliance in the UK context.

4. Using the Calculator

Tips: Enter emission quantity in kilograms and the UK-specific conversion factor. Both values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is Global Warming Potential (GWP)?
A: GWP is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, compared to carbon dioxide.

Q2: Why use UK-specific factors?
A: UK-specific factors account for regional variations in energy mix, transportation, and other factors that affect the carbon intensity of activities.

Q3: Where can I find UK conversion factors?
A: UK conversion factors are typically published by government agencies such as the Department for Business, Energy & Industrial Strategy (BEIS).

Q4: What time horizons are used for GWP?
A: Common time horizons are 20, 100, or 500 years, with 100 years being the most frequently used standard.

Q5: Are all greenhouse gases included in GWP calculations?
A: GWP calculations typically include CO₂, CH₄, N₂O, and various fluorinated gases, each with their own conversion factors.
