Carbon Footprint of Business Trips vs. Online Meetings: What Is The Actual Number?

A carbon footprint represents the total amount of greenhouse gases (GHGs) emitted directly or indirectly by an individual, organisation, event, or product, measured in units of carbon dioxide equivalents (CO2e).

This encompasses all emissions resulting from activities such as burning fossil fuels for electricity, heating, and transportation, as well as the production and consumption of goods and services.

By understanding and managing carbon footprints we can mitigate climate change, as reducing GHG emissions can significantly reduce the potential for global warming.

The Carbon Impact of Business Trips

Business trips, particularly those involving air travel, contribute significantly to our, or our organisation’s carbon footprint. Commercial passenger aircraft emit huge quantities of CO2, and the emissions are magnified when considering long-haul flights. To illustrate this, we can take a look at the carbon footprint of a five-day business trip from Singapore to Bangalore.

Note that the following calculations are based on flying Economy class. For Business Class the Carbon impact is roughly double.

A Singapore to Bangalore Business Trip

Flight Emissions:

• • Distance: The one-way flight distance between Singapore and Bangalore is approximately 3,180 kilometres.

• • CO2 Emissions: The average CO2 emission per passenger kilometre for long-haul flights is about 0.15 kg (Economy Class). Therefore, the round-trip emissions for a single passenger would be approximately: 3,180 km × 2 × 0.15 kg CO2/km = 954 kg CO2

Accommodation:

• • Hotel Stay: Staying in a mid-range hotel typically generates around 15 kg of CO2 per night. For a five-day trip, the total would be: 5 days × 15 kg CO2/day = 75 kg CO2

Local Transportation:

• • Daily Commute: Assuming a modest daily travel footprint of 10 kg CO2 for local transportation, the total for five days would be: 5 days × 10 kg CO2/day = 50 kg CO2

Other Activities:

• • Miscellaneous: Dining out, attending meetings, and other activities might add another 20 kg CO2.

Combining these elements, the total carbon footprint for the trip would be: 954 kg + 75 kg + 50 kg + 20 kg = 1,099 kg CO2

Versus Staying Local + Online Meetings

Online meetings, facilitated through platforms like Zoom, Microsoft Teams, or Google Meet, have drastically reduced the need for business travel. The carbon footprint of online meetings is significantly lower, as they primarily just rely on electricity.

Electricity Consumption:

• • Device Usage: The average power consumption for a laptop is about 50 watts. For an eight-hour meeting, this would be: 50 W × 8 hours = 0.4 kWh
    With the global average CO2 emission factor for electricity at about 0.5 kg CO2/kWh, the total CO2 emission would be: 0.4 kWh × 0.5 kg CO2/kWh = 0.2 kg CO2

Internet Usage:

• • Data Transmission: The carbon footprint for data transmission over the internet is estimated at 0.06 kg CO2 per GB. Assuming a high-definition video meeting uses about 1 GB per hour, for an eight-hour meeting: 8 hours × 1 GB/hour × 0.06 kg CO2/GB = 0.48 kg CO2

Summing these, the total carbon footprint for an eight-hour online meeting would be: 0.2 kg CO2 + 0.48 kg CO2 = 0.68 kg CO2

Local Commuting:

• • Daily Commute: Assuming a daily commute of 10 km by car, with an average car emitting about 0.24 kg CO2 per km, the total emissions for five days would be: 10 km × 2 × 5 days × 0.24 kg CO2/km = 24 kg CO2

Home Energy Consumption:

• • Electricity Usage: The average daily household electricity consumption in Singapore is around 10 kWh. For five days, the total would be: 10 kWh/day × 5 days = 50 kWh

    With the CO2 emission factor at 0.5 kg CO2/kWh, the total emissions would be: 50 kWh × 0.5 kg CO2/kWh = 25 kg CO2

Combining these, the total local carbon footprint for five days would be: 24 kg CO2 + 25 kg CO2 = 49 kg CO2

When added to the online meeting footprint: 49 kg CO2 + 0.68 kg CO2 = 49.68 kg CO2

The CO2 Impact of Making The Trip To Bangalore Vs Conducting Virtual Meetings

If we deduct the staying local CO2 estimate of 49.68 kg from the Bangalore travel CO2 estimate of 1,099 kg then we have an estimated impact of:

1,049.32 kg CO2

Weighing the Intangible Benefits

While the carbon savings of online meetings are clear, there is no denying that there can be substantial, sometimes intangible, benefits of face-to-face interactions, which we will often consider to justify the higher carbon footprint of business travel. Examples being:

Building Relationships: Face-to-face meetings often foster stronger relationships, trust, and rapport. Non-verbal cues, body language, and the overall personal touch can enhance communication and collaboration, leading to better business outcomes.

Networking Opportunities: Physical presence at meetings, conferences, or events provides networking opportunities that virtual platforms cannot fully replicate. These interactions can lead to new partnerships, business deals, and opportunities for professional growth.

Effective Communication: Complex negotiations, conflict resolution, and brainstorming sessions are often more effective in person. The immediacy and nuance of face-to-face communication can result in quicker, more decisive actions and solutions.

Cultural Sensitivity: In international business, understanding and respecting cultural nuances is crucial. Face-to-face interactions can help bridge cultural gaps, enhance mutual understanding, and foster stronger international relationships.

Balancing Act: Sustainable Business Practices

The challenge for modern businesses is to balance the carbon impact with the benefits of in-person meetings. Here are some strategies to achieve a balance:

Hybrid Meetings: Combining virtual and in-person meetings can optimise both carbon footprint and business benefits. Key stakeholders can meet in person, while others join virtually.

Carbon Offsetting: Businesses can invest in carbon offset projects, such as reforestation or renewable energy, to mitigate the carbon footprint of necessary travel.

Smart Scheduling: Consolidating multiple meetings into a single trip can reduce the frequency of travel and associated emissions.

Investing in Technology: Enhancing virtual meeting technology to improve the experience and effectiveness can reduce the need for travel.

Promoting Remote Work: Encouraging remote work and flexible schedules can decrease the overall need for travel, reducing the company’s carbon footprint.

In Summary

When we run the numbers as above and actually consider what the carbon impact of a business trip of just one individual can involve, it should make us think very hard about booking that flight. We often talk about Carbon Footprint but most of us have little knowledge of what that actually means.

No doubt face-to-face interactions are far more effective for the reasons listed but at what cost to the environment?
