• Monthly Streaming Hours: Add the hours you spend watching videos online, for example, 35 or 50, and select the corresponding streaming quality.
• Streaming Quality: Choose from Standard Definition (SD), High Definition (HD), or Ultra HD (4K) to reflect your streaming resolution.
• Monthly Video Call Hours: Enter your video conferencing time, like 15 hours or 45 hours, typically used for remote meetings or social calls.
• Cloud Storage (GB): Record the amount of data you store in the cloud, such as 80 GB or 300 GB.
• Monthly Social Media Hours: Track the time spent on social platforms, examples include 25 hours or 70 hours per month.
• Device Type: Select your primary device used for internet activities, like a smartphone or desktop computer.
• Renewable Energy Use: Check if your home uses renewable energy to adjust emissions accordingly.

What Is the Digital Carbon Footprint Calculator?

This tool estimates the carbon emissions generated by your digital lifestyle. It calculates the greenhouse gases linked to your internet use, streaming, emailing, cloud storage, and device energy consumption. By understanding your digital carbon footprint, you can take actionable steps to reduce your environmental impact.

Purpose and Benefits

• Raise Awareness: See how your digital habits contribute to carbon emissions.
• Encourage Change: Identify high-impact behaviors and adjust them to lower your footprint.
• Track Your Impact: Monitor monthly changes in your carbon emissions.
• Support Sustainability: Make informed decisions about energy use and online activity.
• Save Costs: Reduce unnecessary digital data use and device energy consumption.

How the Digital Carbon Footprint Is Calculated

The calculator uses energy consumption data and regional carbon intensity values to estimate emissions. It combines factors such as electricity sources, device efficiency, and usage patterns to provide a detailed analysis.

Core Emissions Formula

The primary basis for calculation is:

$$ \text{Carbon Emissions (kg CO}_2\text{e)} = \text{Energy Consumption (kWh)} \times \text{Carbon Intensity (kg CO}_2\text{e/kWh)} $$

Activity-Specific Calculations

• Data Transfer Emissions: Calculated by multiplying your data usage in gigabytes, the energy consumption per gigabyte, and your region’s carbon intensity:
  $$ \text{Data Transfer Emissions} = \text{Data (GB)} \times 0.06\, \text{kWh/GB} \times \text{Carbon Intensity} $$
• Streaming Emissions: Based on hours streamed, streaming quality factor, and carbon intensity:
  $$ \text{Streaming Emissions} = \text{Hours} \times \text{Quality Factor} \times \text{Carbon Intensity} $$
• Email Emissions: Calculated by combining emissions from emails without and with attachments:
  $$ \text{Email Emissions} = (\text{Simple Emails} \times 0.0003) + (\text{Attachment Emails} \times 0.00365) $$

Example Calculation of Monthly Digital Carbon Footprint

Suppose you have this monthly digital profile:

• Location: United Kingdom (carbon intensity approx. 0.230 kg CO₂e/kWh)
• Data Transfer: 100 GB
• Emails: 400 without attachments, 50 with attachments
• Streaming: 40 hours in Standard Definition (SD)
• Video Calls: 15 hours
• Cloud Storage: 120 GB
• Social Media: 20 hours
• Device: Smartphone
• Renewable Energy: Yes

Calculation:

$$ \text{Data Transfer} = 100 \times 0.06 \times 0.230 = 1.38 \, \text{kg CO}_2\text{e} $$$$ \text{Emails} = (400 \times 0.0003) + (50 \times 0.00365) = 0.355 \, \text{kg CO}_2\text{e} $$$$ \text{Streaming} = 40 \times 0.05 \times 0.230 = 0.46 \, \text{kg CO}_2\text{e} $$$$ \text{Video Calls} = 15 \times 0.025 \times 0.230 = 0.086 \, \text{kg CO}_2\text{e} $$$$ \text{Cloud Storage} = 120 \times 0.00072 \times 720 \times 0.230 = 14.33 \, \text{kg CO}_2\text{e} $$$$ \text{Social Media} = 20 \times 0.02 \times 0.230 = 0.092 \, \text{kg CO}_2\text{e} $$$$ \text{Device Usage} = (20 + 40 + 15) \times 0.005 = 0.375 \, \text{kWh} $$Since renewable energy is used, the device emissions are not multiplied by carbon intensity.

Total Monthly Emissions: Summing all emissions gives approximately 17.058 kg CO₂e per month.
