Global carbon dioxide emissions from fossil fuels and industry totaled 37.01 billion metric tons (GtCO₂) in 2023. Emissions are projected to have risen 1.08 percent in 2024 to reach a record high of 37.41 GtCO₂. Since 1990, global CO₂ emissions have increased by more than 60 percent....
The baseline scenario projects an increase in anthropogenic emissions an additional 20% beyond the absorptive capacity of natural sinks by 2100 (RAF=2.3±0.6) (cf.Fig. 1). In the nominal energy pathway, REs (that is, solar, wind and biomass) grow at an average annual rate of 4.0% from ...
exposing sediments to the atmosphere. Yet, data on carbon dioxide (CO2) emissions from these sediments are too scarce to upscale emissions for global estimates or to understand their fundamental drivers. Here, we present the results of a global survey covering 196 dry inland waters across...
U.S. CO₂ emissions from energy consumption have fallen by approximately 20 percent since 2005. Sources of emissions in the U.S. The main source of CO₂ emissions in the U.S. is the transportation sector. For many years, the power sector was the country’s biggest contributor to CO...
Depending on the COVID-19 recovery scenario, the study found that investing in green energy infrastructure, including energy efficiency, had "by far the strongest effect on reducing emissions." The study recommended to directly support zero-emission technologies and vehicles and to accelerate research...
Global CO2 emissions from cement production, 1928–2018 Global production of cement has grown very rapidly in recent years, and, after fossil fuels and land-use change, it is the third-largest source of anthropogenic emissions of carbon dioxide. The availability of the required data for estim.....
2, Pages 1742-1764: Addressing Climate Change at the State and Local Level: Using Land Use Controls to Reduce Automobile Emissions Automobiles are a major source of CO2 emissions. Because there is no immediate technological fix to reduce these emissions, the most promising current strategy is to...
In contrast to many discussions based on annual emissions, this article presents calculations and projections of cumulative contributions to the stock of atmospheric CO2 by the major players, China, Europe, India, Japan and the USA, for the period 19002080. Although relative contributions to the cli...
The switching among fossil fuels has also reduced emissions by 329 tons. The power sector has become less carbon intensive partly as natural gas-fired generation took over coal-fired and petroleum-fired generation. In 2016, natural gas generation surpassed coal as the largest source of electricity...
Freshwater reservoirs are considered as the source of atmospheric greenhouse gas (GHG), but more than 96% of global reservoirs have never been monitored. Compared to the difficulty and high cost of field measurements, statistical models are a better choice to simulate the carbon emissions from rese...
