IBM’s total operational greenhouse gas (GHG) emissions totaled 364,000 metric tons of carbon dioxide equivalent (tCO₂e) in 2023, a 15 percent reduction compared to the previous year.
The main source is coal combustion, followed by natural gas. Power generation is the main contributor to these emissions. Reducing the level of emissions to control global warming will therefore have a big impact on the power sector. The international effort to limit global warming is being led...
Emissions are given in real mass per year and in CO2-equiv. mass per year. GWP, global warming potential; HFC, hydrofluorocarbon. Source. IEA (1999); rounded values. 1.2 Methodological Basis and Scope of Comparisons The most straight-forward accounting of GHG emissions can be based on emissio...
The most abundant of the GHGs, CO2 emissions represent three-quarters of all human-caused GHG emissions. The primary source of CO2 emissions is the burning of fossil fuels such as coal, oil and natural gas for energy and transportation. CO2 is also released through deforestation and other land...
NAIROBI, Jan. 23 (Xinhua) -- Kenya has embarked on an effort towards capturing greenhouse gas (GHG) emissions from the livestock subsector, a government official said on Tuesday. Andrew Tuimur, Livestock Principal Secretary, said that the East African nation is developing a Measurement, Reporting...

Figure 2: This figure, also based on the classification of emission sources in ISO 14064-1, categorizes greenhouse gas emissions into three major categories.(Source: iST) (2) How to Select Emission Factors and GWP Values Correctly i. Emission Factors ...
Carbon emission reduction in the transportation sector is essential in the global mitigation effort, and a large-scale public transport system has the potential to be an effective instrument. High-speed rail (HSR) is one such example, yet it is unclear h
This value includes a minor amount of CH4 and N2O emissions inherent in the production of some inputs whose greenhouse gas emissions were reported according to the kg CO2e/kg product emitted by their production. 3.3. Emissions profiles by source Enteric CH4 was the major source of GHG emissions...
Current understanding of GHG emissions in SSA is particularly limited when compared to the potential the continent has as both a GHG sink and a source (Kim et al., 2016; Boateng et al., 2017). Limited data and information on agricultural production in Africa make it difficult to quantify ...
