米国におけるCO2排出量の新たな増加.

CO2排出量の増加(+ 1.9%)は過去の増加に基づく

経済成長の鈍化、エネルギー原単位の低下、および燃料構成の変化に関連して、2016年までの3年間の排出量の停滞の後、エネルギー関連CO2排出量は2017年に2.1%、2018年に1.9%増加しました。 石炭とガスの切り替え政策にもかかわらず、中国(+ 3.1%)、インド(+ 4.2%)、ロシア(+ 3.9%)で排出量が増加しています。
米国では、部分的に気象条件によってエネルギー消費量が増加したため、CO2排出量は3.1%増加しました。
欧州連合では、エネルギー需要の減少(ドイツなど)、発電用の再生可能エネルギーの寄与の大きさ、および天候(穏やかな天候)のため、CO2排出量が減少しました(-2.1%)。
日本では、2016年以降の太陽光発電の貢献度の増加と2018年の原子力発電の増加により、CO2排出量は5年連続で減少し続けました。

US EIA expects 90 GW of coal-fired power plants to retire by 2030

According to the US Energy Information Administration (EIA), the US coal-fired power capacity fell by around 60 GW between 2011 and 2017 as a result of power plant retirements, which were due to high operating and maintenance costs. Sustained relatively low gas prices have made coal-fired power plants less competitive and less used, reducing revenues and operating margins for their operators, prompting them to retire these coal-fired units. A study led by the EIA highlights that coal-fired power plants with the lowest variable operating and maintenance costs have higher capacity factors (59% in 2017) than the coal fleet average (54%) and than the highest cost group (47%).

Japan's greenhouse gas emissions fall to record low in 2018/19

According to Japan National Institute for Environmental Studies, the country’s greenhouse gas (GHG) emissions have declined from 1,291 MtCO2 in the financial year 2017/18 to 1,244 MtCO2 in 2018/19 (-3.6%), which is their lowest level since 1990/91. It was the fifth year in a row of decline, which was mainly driven by the increased use of renewable energies and the restart of nine nuclear reactors. As the world’s fifth-biggest carbon emitter, Japan aims at reducing its GHG emissions by 26% by 2030 (from 2013 levels). The observed decrease stood at 11.8% at the end of 2017/18.

US wind capacity exceeds 100 GW mark

According to the American Wind Energy Association (AWEA), the installed wind power capacity in the United States has reached 100 GW in the third quarter of 2019 (from over 94 GW at the end of 2018), enough to supply power to 32 million US households. Wind installations accelerated in the third quarter of 2019, with 8 new large power projects totalling 1.9 GW commissioned.

GHG emissions under the EU ETS scheme fell by 4.1% in 2018

According to the annual report on the functioning of the European carbon market, greenhouse gras (GHG) emissions from installations covered by the EU ETS decreased by 4.1% (around 73 MtCO2eq) to 1,682 MtCO2eq in 2018, thanks to a 7.3% drop in emissions from the power and heat production sector (down to 913 MtCO2eq). Verified emissions from the industrial sector remained stable (-0.1%) at 769 MtCO2eq, while those from aviation grew by 3.9% to 67 MtCO2eq.
