New energy efficiency improvement in the USA in 2020, twice the 2000-2019 pace
Significant slowdown in energy intensity improvement in 2020 (-0.4%, vs. -1.5%/year over 2000-2019)
Global energy intensity (total energy consumption per unit of GDP) dipped by 0.4% only in 2020, i.e. much slower than its historical trend (-1.5%/year on average between 2000 and 2019), widening again the gap with the 3.5%/year decrease required to achieve the 2°C scenario. This slowdown is mainly due to the economic recession in 2020, which had a negative impact on economic activity, but did not reduce energy consumption to the same extent (the economic downturn affected all sectors, such as services, not only the most energy-intensive). Energy intensity levels and trends differ widely across world regions, reflecting differences in economic structure and energy efficiency achievements. Since 2000, the USA and the EU have cut their energy intensity by around 2%/year thanks to energy efficiency efforts (especially in the power sector) and to a lesser extent to a structural shift toward less energy-intensive industry branches and the growing share of services in the GDP. In 2020, the improvement was much slower in the EU (-0.6%), whereas it accelerated in the United States (-4.2%). China’s energy intensity remained stable in 2020 (+0.4%, compared to a 2.9%/year improvement over the 2000-2019 period). In 2020, its energy intensity stood 43% below its 2000 level, still 27% above the world average. The high energy intensity in the CIS, the Middle East, China and some Asian countries (Taiwan, South Korea) is explained by the dominance of energy-intensive industries, commodity exporting-based economies and low energy prices that do not encourage energy efficiency. In 2020, energy intensity increased in Asia (especially in India and China, improving in other countries), in Australia, in the Middle East, in Africa (strong growth in Nigeria and South Africa, contrasting with improvements in Algeria and Egypt) and in Latin America to a lesser extent (increase in most countries except Mexico). On the contrary, energy intensity improved in Canada and Russia, though remaining much higher than the global average.
Iran exported 17 bcm of natural gas in the past year (March 2021-March 2022), according to the National Iranian Gas Company (NIGC), including 7.3 bcm to Iraq (43%) and 3.3 bcm to Turkey (19%). Around 98% of cities and 85% of villages in the country are connected to the natural gas transmission network. In 2020, Iran exported 11.3 bcm of natural gas and Iraq sourced 100% of its natural gas imports from Iran, totalling 5.7 bcm in 2020.
Greenhouse gas (GHG) emissions under the EU Emissions Trading System (EU ETS) rose by 7.3% in 2021, due to higher emissions from the power sector, industry and aviation; however, they remain below their 2019 levels.
India's crude oil production declined by 2.7% in the fiscal year 2021-2022 (April 2021 to March 2022) to 29.7 Mt, in line with the recent decrease in oil production due to ageing fields. Oil and Natural Gas Corporation (ONGC) produced 19.45 Mt of crude oil (-3.6%). With the economic recovery, refineries processed 242 Mt of crude oil in the fiscal year 2021-2022 (+9%), producing 254 Mt of petroleum products (+8.9%). In addition, natural gas output rose by 18.7% to 34 bcm in the fiscal year 2021-2022.
US greenhouse gas (GHG) emissions (including LULUCF) declined by 11% in 2020 to 5,222 MtCO2eq, i.e., 21% below 2005 levels, according to the United States Environmental Protection Agency. This was driven by an 11% decrease in CO2 emissions from fossil fuel combustion, primarily due to a 13% drop in transportation emissions driven by lower demand owing to the COVID-19 pandemic. In addition, power sector emissions also fell by 10%, reflecting both a slight decline in demand from the COVID-19 pandemic and a continued shift from coal to natural gas and renewables. In 2020, CO2 accounted for 79% of total emissions, followed by methane (11%), nitrous oxide (7%) and fluorinated gases (3%). Transport is the largest emitter sector (27%), followed by electricity (25%), industry (24%), commercial and residential (13%) and agriculture (11%).
