Analysis of the total carbon dioxide emissions of countries since 1850 has revealed the nations with the greatest historical responsibility for the climate emergency. But six of the top 10 have yet to make ambitious new pledges to cut their emissions before the crucial UN Cop26 climate summit in Glasgow in November. The six include China, Russia and Brazil, which come only behind the US as the biggest cumulative polluters. The UK is eighth and Canada is 10th. Carbon dioxide remains in the atmosphere for centuries and the cumulative amount of CO2 emitted is closely linked to the 1.2C of heating the world has already seen. The analysis, produced by Carbon Brief, includes, for the first time, emissions from the destruction of forests and other changes in land use alongside fossil fuels and cement production. This pushes Brazil and Indonesia into the top 10, unlike when fossil fuel emissions alone are considered. The data also shows the world has now used 85% of the CO2 budget that would give a 50% chance of limiting heating to 1.5C, the danger limit agreed in Paris in 2015.

Luxury yachts, private jets and other carbon-intensive goods used by the “polluter elite” should be banned or heavily taxed in order to meet global climate change targets, a report says. Scientists studied the carbon footprints of people in nine G20 countries, including the UK, and analysed how lifestyles would have to change to meet the Paris Agreement target of limiting global warming to 1.5C. The footprint of people in high income countries such as the UK would have to fall by more than 90 per cent by 2050, according to the report co-written by scientists from the Universities of Oxford, Sussex and Lausanne and published by the Hot or Cool Institute think tank. It says that the 1.5C target means that the UK’s average lifestyle carbon footprint per person has to decline from 8.5 tonnes of carbon dioxide in 2019 to 0.7 tonnes by 2050. It identifies four “especially problematic” lifestyle choices: “Eating meat, using fossil fuel cars, flying and large and high energy-consuming houses.”
