In a 2023 study, Oxfam International found that the richest 1% globally – 77 million people – were responsible for 16% of global emissions related to their consumption. That is the same share as the bottom 66% of the global population by income, or 5.11 billion people. The report advocated that on this basis, policy actions must be progressive. "We think that unless governments enact climate policy that is progressive, where you see the people who emit the most being asked to take the biggest sacrifices, then we're never going to get good politics around this," one of the authors said. These measures could include, for example, a tax on flying more than ten times a year, or a tax on non-green investments that is much higher than the tax on green investments. While the report focused on carbon linked only to individual consumption, "the personal consumption of the super-rich is dwarfed by emissions resulting from their investments in companies," the report also found. Not only that, billionaires are twice as likely to invest in polluting industries than the average investor, previous Oxfam research has shown. The message is clear: Governments need to hold the wealthy to account for their emissions footprints through tax. Both their personal spending, and their investments. Vote here if you agree.
