The study shows that just 25 mega-cities produce 52% of the greenhouse gas emissions from the studied cities. Asian cities emit the most greenhouse gasses (GHG), and most cities of developed countries had significantly higher per capita GHG emissions than those of developing countries. The authors propose three key policy recommendations. A BAU scenario was created by fixing non-electric CO2 emissions for each sector at 1990 per-capita levels, or at the year at which per-capita emissions started declining if they increased after 1990. The year chosen as the start of the BAU scenario was 1990 for business, 1998 for residential, 1997 for public buildings and agriculture, 1990 for Emissions Factors 2022. The Emissions Factors database includes the following indicators related to emissions from electricity and heat generation: CO2 emission factors from electricity and heat generation for world countries (in CO2 per kWh, 1990 to 2020). CO2 emission factors from electricity only generation (CHP electricity included) for According to Statistics Finland’s preliminary data, the total emissions of greenhouse gases in 2020 corresponded with 48.1 million tonnes of carbon dioxide (CO2 eq.). Emissions fell by nine per cent from the previous year. The fall in emissions was affected by the warm winter, recent changes in the production structure of electricity and the 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’. CO 2 emissions per capita. CO 2 emissions per capita measure the average annual emissions per person for a country or region. It is calculated by dividing the total annual emissions of the country or region by its total population. The source for the annual CO 2 emissions data is the Global Carbon Project, as described above. Per capita emissions represent the emissions of an average person in a country or region - they are calculated as the total emissions divided by population. This data is based on territorial emissions, which do not account for emissions embedded in traded goods. Emissions from international aviation and shipping are not included in any country 13.
