If every country were to meet its stated climate goals, America’s per capita emissions would decline and converge with China’s by 2030, the Rhodium Group estimated. An increasing number of countries, sub-national governments and companies, have made net-zero GHG emissions pledges. As of 1 September 2022, net-zero targets have been adopted or proposed by 136 countries and the European Union (Figure 3). These targets cover around 83% of global carbon emissions. Enlarge / Per capita emissions for the top 4 countries/groups. The solid line simply calculates emissions taking place within their borders, while the dashed line adjusts for consumption of goods The USA has emitted most to date: more than a quarter of all historical CO 2: twice that of China which is the second largest contributor. In contrast, most countries across Africa have been responsible for less than 0.01% of all emissions over the last 266 years. What becomes clear when we look at emissions across the world today is that the This is because the emissions growth recorded in China and India suggests that citizens of these countries are now the biggest contributors to climate change. In reality, however, even after the dramatic growth recorded over the past three decades, per capita emissions remain higher in both Europe (7.3 MtCO2) and the US (16.1 MtCO2) than China Total emissions and emissions per capita declined from 2007 to 2009, due in part to a drop in U.S. economic production during this time. Emissions decreased again from 2010 to 2012 and continued downward largely due to the growing use of natural gas and renewables to generate electricity in place of more carbon-intensive fuels. 3 Total household carbon footprint across 177 EU regions in tonnes of CO2 equivalent, encompassing both direct and embodied emissions. Note that only national averages are shown for Sweden and the Netherlands. Source: Ivanova et.al 2017. As for the per capita map, this also clearly shows large differences in emissions between regions. Asia is by far the largest emitter, accounting for 53% of global emissions. As it is home to 60% of the world’s population this means that per capita emissions in Asia are slightly lower than the world average, however. China is, by a significant margin, Asia’s and the world’s largest emitter: it emits nearly 10 billion tonnes each year Carbon Dioxide (CO2) Emissions by Country in the world with Global share of CO2 greenhouse emissions by country. Per capita Share of world ; 1: China Most are in the Middle East: In 2017 Qatar had the highest emissions at 49 tonnes (t) per person, followed by Trinidad and Tobago (30t); Kuwait (25t); United Arab Emirates (25t); Brunei (24t); Bahrain (23t) and Saudi Arabia (19t). 8qpgPo2.
