トレンド 1990 - 2020 - kCO2/$15p





2020年には、二酸化炭素強度は1.3%の下降を見せました。背景には、COVID-19パンデミックのために発電業界で石炭から天然ガスや再生可能資源への移行が加速され、輸送における石油の消費量が急減したことがありました。この結果は、2010-2019年の期間(年間-2.3%)よりも減速されました。不景気がサービス業界のような二酸化炭素強度が低い業界にも悪影響を与えたためです。 二酸化炭素強度はOECD諸国で著しく下降しました(米国で-7.5%、欧州連合で-5%、カナダで-11%、韓国で-5.4%)。これは2000-2019年の期間よりもはるかに加速されました。二酸化炭素強度のわずかな下降は、中国(-0.2%。しかし、中国は世界平均よりも63%上にとどまる)、ロシア(-2.3%)、オーストラリアでも見られました。また、ラテンアメリカ(ブラジルとメキシコで下降トレンド)、アフリカ(エジプトとアルジェリアで下降アフリカ南アフリカとナイジェリアで上昇)でも、二酸化炭素強度が低下しました。 国によって二酸化炭素強度のトレンドが異なるアジアでは(GDPが8%減少したインドとタイで上昇、日本とインドネシアでは下降)、わずかな上昇がありました(+0.5%)。また、2020年にエネルギー強度(GDP当たりのエネルギー消費量)が上昇した中東でも、二酸化炭素強度が上昇トレンドを示しました。

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.
