Global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. In 2021 alone, China’s CO 2 emissions rose above 11.9 billion tonnes.

Thus, the Duisburg steelworks is continuing to boil steel as in the past—but with hydrogen and green power instead of coal.
Life-cycle GHG emissions from fossil and alternative sources of electricity. Lead author Kharecha and colleagues note that current climate science indicates that atmospheric CO 2 concentrations, already at 387 ppm in 2009 and rising, need to be reduced to no more than 350 ppm.

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. The climate effects of hydrogen have been an under-researched topic.
Fuel-cycle SO 2 emissions of EVs compared to those of gasoline ICEVs and HEVs in China, current (left) and future (right). The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.
Energy-related carbon-dioxide (CO2) emissions in 2010 were the highest in history, according to the latest estimates by the International Energy Agency (IEA). After a dip in 2009 caused by the global financial crisis, emissions are estimated to have climbed to a record 30.6 tonnes for China, and 1.5 tonnes in India.

Coke is carbon fuel made from coal. RAR is thus the quantity of carbon fuel used in blast furnace ironmaking.
US President Barack Obama said the US will cut net greenhouse gas emissions in the US by 26-28% below 2005 levels by 2025. Together, the US and China account for more than one third of global greenhouse gas emissions. The US and China jointly announced greenhouse gas (GHG) reduction targets. per year on average between 2020 and 2025.
Energy-related CO 2 emissions buy state, 2010. The US Energy Information Administration (EIA) has released a new report, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010. The report shows a significant variation of energy-related carbon dioxide emissions across states on both an absolute and a per capita basis.
The MIT Energy Initiative has released a new report on reducing carbon dioxide emissions from existing coal plants. There is no credible pathway toward prudent greenhouse gas stabilization targets without CO 2 emissions reduction from existing coal power plants. We may not see a strong CO 2 price signal for many years.

Liquid fuels. trillion kilowatthours in 2010 to 5.5
A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. The paper is published in Nature Communications.
Global carbon dioxide emissions show no sign of abating and may reach record levels in 2010, according to a study led by the University of Exeter (UK). The global financial crisis severely affected western economies, leading to large reductions in CO 2 emissions. For example, UK emissions were 8.6% below the record 2008 figures.
The President’s Council of Advisors on Science and Technology (PCAST) released a letter to President Obama describing six key components the advisory group believes should be central to the Administration’s strategy for addressing climate change. Both approaches are essential parts of an integrated strategy for dealing with climate change.
Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge. BIT:ENI) recently unveiled what has been hailed as the most ambitious climate pledge yet by an oil supermajor. Eni has announced plans to cut down its greenhouse gas emissions by 80% over the next three decades.
Removing fossil fuel subsidies would have only a small effect on CO 2 emissions and renewable energy use, according to a new study led by the International Institute for Applied Systems Analysis (IIASA) and published in the journal Nature. That means that in some cases the removal of subsidies causes a switch to more emissions-intensive coal.
Compared with conventional steel, bluemint Steel used for sustainable wheel production offers emission savings of 70% up to the hot strip production stage. This enables less coal to be used for the reduction process, resulting in reduced emissions. In this way, the CO 2 intensity of each metric ton is reduced by 1.5 metric tons.
Researchers have measured CO 2 emissions from fossil fuel use in California and compared them to reported emissions. This is the first time fossil fuel emissions have been independently checked for such a large area. Fossil fuels lack a type of radioactive carbon, an isotope called carbon-14, which decays over time.
Global CO 2 emissions from fuel use and cement production by region. Emissions increased by 1.7% Global CO2emissions increased from 15.3 The lower increase in CO 2 emissions was mainly due to a decrease in global fossil oil consumption of about 0.6%, the first global decrease since 1992.
