Climate change and flying: what share of global CO2 emissions come from aviation?

Flying is a highly controversial topic in climate debates. There are a few reasons for this. The first is the disconnect between its role in our personal and collective carbon emissions. Air travel dominates frequent travellers’ individual contributions to climate change. Yet aviation overall accounts for only 2.5% of global carbon dioxide (CO2) emissions. This Read more about Climate change and flying: what share of global CO2 emissions come from aviation?[…]
