The study will appear next month in the peer-reviewed journal Climatic Change Letters. The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. —Tom Wigley.
A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011. The CO 2 emissions from burning this coal will also decline by 50%.
The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.
This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.

Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1
The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data, but the overall decline of about 6% masks wide variations depending on the region and the time of year. But our numbers show we are returning to carbon-intensive business-as-usual.
This reduction is achieved through a closed-loop carbon recycling system, which could replace 90% of the coke typically used in current blast furnace-basic oxygen furnace systems and produces oxygen as a byproduct. A double perovskite, Ba 2 Ca 0.66 This reacts with the iron ore in the furnace to produce CO 2.

All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon.
The report—titled “The Role of China in Mitigating Climate Change” and published in the journal Energy Economics , compares the impact of a stringent emissions reduction policy with and without China’s participation. The researchers tested various levels of emission reduction plans—a global carbon tax of $10, $30 or $50.
Plastics are on track to contribute more greenhouse gas emissions than coal plants in the US by 2030, according to new report by Beyond Plastics, a nationwide project based at Bennington College in Vermont. This report represents the floor, not the ceiling, of the US plastics industry’s climate impact. million tons of GHG each year.
“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Our analysis assumes that captured carbon dioxide can be stored indefinitely, an optimistic and unproven assumption.
Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. Air pollution mitigation efforts focusing on reducing combustion pollution are likely to have major benefits for climate and human health.
A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. Recent reports in the scientific literature and popular press have produced confusion about the climate implications of natural gas.
To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine.
It aims to replace coking coal, traditionally needed for iron ore-based steelmaking, with fossil-free electricity and hydrogen. The result is expected to be fossil-free steelmaking technology, with virtually no carbon footprint. By 2040, Volvo Cars’ ambition is to be a climate-neutral company.
A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. Black carbon is released into the atmosphere via incomplete combustion of carbonaceous fuel and is of major concern because of the impact on climate systems. Click to enlarge.

A NASA-led team of scientists has uncovered strong evidence that coal soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age (LIA). Black carbon is the strongest sunlight-absorbing atmospheric particle.
In a fairly bleak assessment of global progress towards low-carbon energy, the International Energy Agency (IEA) concluded that, despite a few bright spots such as the rapid expansion of renewable technologies and the growth of hybrid and EV sales, the progress is far below that required to achieve a 2 °C pathway—i.e., Source: IEA.
India’s energy landscape is at a pivotal crossroads, exemplified by the notable recent decline in coal- and gas-fired power generation, which in May 2025 marked the steepest year-over-year drop since COVID-19.
Since carbon dioxide is not emitted when ammonia (NH 3 ) is burned, it is viewed to have promise as a next-generation fuel that could mitigate shipping’s impact on global warming. In particular, a significant reduction in CO 2 emissions is expected to be achieved by replacing coal and natural gas as the main fuels for power generation.
