Slowdown in the reduction in global CO2 intensity in 2020 (-1.3%)

In 2020, the CO2 intensity declined by 1.3%, as the COVID-19 pandemic accelerated the fuel substitution of coal by gas and renewables in the power sector and led to a strong decline in oil consumption in transports. This remains slower than over the 2010-2019 period (-2.3%/year), as the economic downturn also impacted less CO2-intensive sectors such as services. The CO2 intensity decreased significantly in OECD countries (-7.5% in the USA, -5% in the EU, -11% in Canada, -5.4% in South Korea), much faster than over the 2000-2019 period. It slightly declined in China (-0.2%, even if it remains 63% above the global average), in Russia (-2.3%), and in Australia. It also contracted in Latin America (declining trend, especially in Brazil and Mexico) and Africa (declines in Egypt and Algeria but growth in South Africa and Nigeria). The CO2 intensity slightly increased in Asia (+0.5%), though with various trends in countries (growth in India and in Thailand, where the GDP fell by 8%, but declines in Japan and Indonesia). As well, it tended to rise in the Middle East, where the energy intensity (energy consumption per unit of GDP) increased in 2020.

All the information presented in this energy data tool are extracted from Global Energy & CO2 Data service, the most comprehensive and up-to-date database on all CO2 emissions from fuel combustion by sector and sources, industrial process, waste, but also on CH4, N2O, PFC, SF6 emissions. Detailed indicators are available by country and by sector.

According to Ireland's Environmental Protection Agency, the country's greenhouse gas (GHG) emissions decreased by 3.6% in 2020 to 58 MtCO2eq. The decrease in emissions is reflected in most sectors with the exception of increases in residential, agriculture  and public services. In the energy sector, GHG emissions fell by 7.9% (-0.74 MtCO2eq), as peat-fired power generation halved and renewable power generation increased noticeably (+15% from wind), covering 42% of the Irish power mix. Residential emissions grew by 9% (+0.59 MtCO2eq), as a result of colder temperatures, historic low oil prices (impacting heating choices), and home working. Emissions from transports fell by nearly 16% (-1.9 MtCO2eq) due to transport restrictions. Overall, Ireland's GHG emissions are still only 7% below 2005 level. The country committed under an EU agreement known as the Effort Sharing Decision to cut GHG emissions by 20% between 2005 and 2020.



According to the Global Wind Energy Council (GWEC), 6.1 GW of offshore wind capacity was installed in 2020 (down from 6.2 GW in 2019), including 3 GW in China, 1.5 GW in the Netherlands, and 0.7 GW in Belgium. More than 35 GW of offshore wind capacity is currently operational, with 29% of the total in the UK, 28% in China and 22% in Germany.



South Africa’s total greenhouse gas emissions excluding FOLU (forestry and other land use) increased by 14% between 2000 and 2017 to 513 MtCO2eq, according to the country’s 7th National Greenhouse Gas (GHG) Inventory Report. The energy sector is the largest contributor to emissions excluding FOLU (80%) and is responsible for 97% of the increase over 2000-2017. Energy industries were responsible for 61% of emissions from the energy sector in 2017. This was followed by transport (13%), other sectors (9%) and manufacturing industries and construction (7%).



According to the Turkish Electricity Transmission Corporation (TEIAŞ), installed wind capacity in Turkey reached the 10 GW threshold in early August 2021. Most of the capacity is located in the Izmir province (1.7 GW), followed by Balıkesir (1,300 MW), Çanakkale (850 MW), Manisa (750 MW), and Istanbul (420 MW). Wind represented 10% of the installed capacity connected to the transmission network (10,010 MW out of 98,800 MW) and over half (51.9 GW) was considered "clean" electricity. In the first half of 2021, wind power accounted for around 9% of the power generation, replacing nearly US$1bn in gas imports.
