国別内訳 (tCO2/toe)

トレンド 1990 - 2020 - tCO2/toe





2020年には世界の炭素係数(石油換算トン当たりのエネルギー消費のCO2排出量)が0.9%減を記録しました。これは、2010-2019年の期間の減少(年間-0.3%)よりもはるかに速いペースでした。このような改善は、パンデミックに関係した都市封鎖措置と輸送制限の状況での石油消費量の急減と、発電における脱炭素化が加速されたことが背景にあります(電力消費量の落ち込みのために、火力発電を主とする柔軟性のある発電設備で発電電力量が減少)。実際には、電力消費量の減少と再生可能エネルギー発電の増大の継続が、(特に石炭を使用した)火力発電、そして発電業界における化石燃料の消費量減少に貢献しました。 炭素係数の低下は、欧州連合(-4.4%。スペインとドイツで著しく減少)、米国(-3.4%)、カナダ(-9.5%)、ラテンアメリカおよびアフリカ(それぞれ-4.4%。火力発電が減少した南アフリカで著しい改善)で、記録されました。 アジアではこの改善は鈍速しています(-0.6%)。(石炭消費量が今もなお増加中の)中国では、炭素係数の低下は0.5%にとどまりました。炭素係数の低下は、インド(石炭火力発電の縮小)、韓国(原子力発電の増加)で見られましたが、日本とインドネシアでわずかに上昇しました。炭素係数の低下は、石炭消費量を縮小したロシアとオーストラリア、そして中東(石油消費量の縮小)でも記録しました。

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.
