The researchers found that emissions from global tourism increased by 3.5% annually, reaching 5.2 gigatonnes of carbon dioxide equivalent in 2019
Global tourism-related carbon dioxide emissions have increased over the past decade, a study published in the journal Nature Communications has found.
The researchers studied data from 2009 to 2020 from 175 countries. They found that emissions from global tourism increased by 3.5% annually, reaching 5.2 gigatonnes of carbon dioxide equivalent in 2019. According to the researchers, this equates to 8.8% of total global greenhouse gas emissions, or with five times the annual emissions of France. In fact, carbon dioxide emissions from tourism are growing more than twice as fast as global emissions.
The study also reveals notable differences in per capita emissions due to tourism, with the 20 highest-emitting countries, including the US, China and India, contributing three-quarters of the total carbon footprint.
The findings, the scientists point out, highlight the urgent need for effective policy measures to align the tourism sector with global climate goals.
