1:Global CO2 Emissions from Checked Baggage

We have previously analyzed the reduction in CO2 emissions by not carrying checked baggage on airplanes to Japan. This time, we will analyze CO2 emissions from checked baggage in the global airline industry.

According to “Project Drawdown,” CO2 emissions from the global aviation industry accounted for about 2.6% of global emissions in 2018. According to the World Bank, global CO2 emissions in 2018 were 34.29 billion tons (34.34 billion tons in 2019), which means that CO2 emissions from the aviation industry were 890 million tons in 2018. Note that according to the International Air Transport Association (IATA), CO2 emissions from the aviation industry in 2019 were 910 million tons.

According to IATA, the global air passenger transport distance (paid passenger kilometers) in 2019 was 8.68 trillion kilometers. Therefore, if all airplanes carried 20 kg of checked baggage by each passenger, 14.51 million tons of CO2 emissions would be from checked baggage. This is 0.3% of the global CO2 emissions of 34.34 billion tons in 2019. It is also 0.23% of global greenhouse gas emissions of 46.29 billion tons of CO2 equivalent in 2019.

The CO2 emissions from checked baggage (20 kg) are based on the data provided by ECTA (European Chemical Transport Association) in their “Guidelines for Measuring and Managing CO2 Emission from Freight Transport Operations 2011” of ECTA (The European Clean Trucking Alliance). The CO2 emissions intensity per ton-kilometer of cargo transported by airplanes used in the calculation is 0.602 kgCO2/tkm.

You may think that 0.3% of global CO2 emissions are small, but 104.51 million tons of CO2 emissions in more than 156 countries, including 96.29 million tons in the Czech Republic and 93.01 million tons in Belgium. You can see how significant the reduction of checked baggage is.

Note: Countries with the highest CO2 emissions and countries with lower CO2 emissions from checked baggage are selected.

 

We analyzed that the reduction in CO2 emissions per year (average of 1.8 trips) from one traveler without 20 kg of luggage traveling to Japan was 137 kg ( “Comparison of 87 CO2 reduction projects“).

145.51 million tonnes of CO2 emissions were from checked baggage worldwide. So dividing this by the 4.543 billion annual number of passengers worldwide, translates into 23 kg of CO2 emissions per person each way. The round-trip CO2 emissions would be 46 kg, and the reduction in CO2 emissions per year per traveler (for one trip per year) by not carrying 20 kg of baggage on board the aircraft would be the 26th largest effect (per global population) of the measures listed in the “Project Drawdown.”

81% of global travelers and 73% of Japanese travelers say that sustainable travel is important to them. Travelers who recognize the importance of sustainable travel should consider not bringing checked baggage. Without checked baggage is the best sustainable travel.

If you don’t bring checked baggage and rent what you need locally, you can have an “easy trip,” as there is no need to prepare and carry baggage or to wash and clean up after you return home. This “easy travel” will make increasing the number of trips for people such as the elderly, disabled people, and families traveling with children. This “easy travel” will also bridge the “Travel Divide.” Please consider using our travel rental service.
