An upper bound of Scope-1 CO 2 emissions were f m a x (g 1) obtained by considering only CH 4 emissions from waste in each city, approximated by national per capita methane waste emissions The first interactive chart shows per capita greenhouse gas emissions. This is measured as the sum of all greenhouse gases, and given by a metric called ‘carbon dioxide equivalents’. ‘Carbon dioxide equivalents’ try to correct for the fact that one unit (e.g. a tonne) of a given gas doesn’t have the same same impact on warming as another. Figure 9: International comparisons for per capita emissions (in million tonnes of carbon dioxide equivalent, Mt CO2-e) in 2018. Annex 1 countries (UNFCCC) are compared with Australia, Japan, New Zealand, the United Kingdom, and the United States of America. Each country shows two bars which represent ‘CO 2 only per capita’ and ‘All gases’. Libya. > CO2 emissions, metric tons per capita, 2019: 6.77. > CO2 emissions, metric tons per capita, 2010: 8.16 — #36 highest of 147 countries. > CO2 emissions per GDP, 2019: 0.40 — #19 Carbon dioxide emissions per capita, 2020: The average for 2020 based on 185 countries was 3.84 metric tons. The highest value was in Qatar: 31.73 metric tons and the lowest value was in Democratic Republic of the Congo: 0.03 metric tons. While the largest CO2 emitter, on a per head basis Germany is the fifth-largest emitter among the EU14, with 8.4 tonnes of CO2 per head. Luxembourg emits around 14.3 tonnes of CO2 per head, more than any other EU14 nation. With per head CO2 emissions of just under 6 tonnes in 2020, the UK emits less than Germany but more than Italy, France and Carbon intensity vs. GDP per capita. Carbon intensity: CO₂ emissions per dollar of GDP. Carbon opportunity costs per kilogram of food. Change in per capita CO₂ emissions and GDP Adjusted for consumption. Change in per capita CO₂ emissions and GDP Production-based. Consumption-based CO₂ emissions. To calculate consumption-based emissions we need detailed trade data between countries and the emissions intensity (the amount of CO2 emitted per dollar spent) across many industries and sectors in each country. Prior to 1990, there is insufficient high-quality, high-resolution data to produce these calculations. ZgwC.
