The difference between the carbon emissions of the rich and the poor within a country is now greater than the differences in emissions between countries, data shows. The finding is further evidence of the growing divide between the “polluting elite” of rich people around the world, and the relatively low responsibility for emissions among the rest of the population. It also shows there is plenty of room for the poorest in the world to increase their greenhouse gas emissions if needed to reach prosperity, if rich people globally – including some in developing countries – reduce theirs, the analysis has found. Most global climate policy has focused on the difference between developed and developing countries, and their current and historical responsibility for greenhouse gas emissions. But a growing body of work suggests that a “polluting elite” of those on the highest incomes globally are vastly outweighing the emissions of the poor. This has profound consequences for climate action, as it shows that people on low incomes within developed countries are contributing less to the climate crisis, while rich people in developing countries have much bigger carbon footprints than was previously acknowledged. In a report entitled Climate Inequality Report 2023, economists from the World Inequality Lab dissect where carbon emissions are currently coming from. The World Inequality Lab is co-directed by the influential economist Thomas Piketty, the author of Capital in the Twenty-first Century, whose work following the financial crisis more than a decade ago helped to popularise the idea of “the 1%”, a global high-income group whose interests are favoured by current economic systems. The report found that “carbon inequalities within countries now appear to be greater than carbon inequalities between countries. The consumption and investment patterns of a relatively small group of the population directly or indirectly contribute disproportionately to greenhouse gases. While cross-country emission inequalities remain sizeable, overall inequality in global emissions is now mostly explained by within-country inequalities by some indicators.” The report also found that although overseas climate aid – a key focus of the recent Cop27 climate negotiations – would be needed to help developing countries reduce their emissions, it would not be enough and developing countries also needed to reform their domestic tax systems to redistribute more from the wealthy. The authors suggest windfall taxes on excess profits could help to fund low-carbon investment, as well as progressive taxation in countries, including developing countries, which often under-tax rich citizens and companies.         https://www.theguardian.com/environment/2023/jan/31/emissions-divide-now-greater-within-countries-than-between-them-study                                                               The scientists behind a new database of more than 400 extreme weather attribution studies have performed an essential service. This piece of work, drawing together every study of this type, ought to galvanise a greater sense of urgency around policymaking and campaigning. It shows that intense heatwaves, hurricanes, droughts and floods have all been made far more likely by greenhouse gas emissions, which trap the sun’s heat and put more energy into weather systems. And it spells out the alarming unpredictability as well as the extent of global heating’s consequences.         https://news.climate.columbia.edu/2021/10/04/attribution-science-linking-climate-change-to-extreme-weather/
