Global average CO2 emission per
tonne cement production is estimated by Worrell et al. (2001b) at 814 kg (222 kg C), while Humphreys and Mahasenan (2002) estimated 870 kg (264 kg C).

Global carbon dioxide emissions from fossil fuel combustion and
cement production grew 2.3 per cent to a record high of 36.1 billion
tonnes CO2 in 2013.
The carbon majors are defined as fossil fuel
production entities and
cement manufacturers that produced more than ≥ 8 million
tonnes carbon per year (MtC / y), while the total human attribution case refers to all relevant human activities that have been measured and used in climate assessment model scenarios that influence climate change.
Emissions of CO2 by human activities, including fossil fuel burning,
cement production, and gas flaring, amount to about 27 billion
tonnes per year (30 billion tons)-LSB-(Marland, et al., 2006)-- The reference gives the amount of released carbon (C), rather than CO2, through 2003.].

cement production — from 1750 to 2011 — was about 365 billion metric
tonnes as carbon (GtC), with another 180 GtC from deforestation and agriculture.
The carbon majors are defined as fossil fuel
production entities and
cement manufacturers that produced more than ≥ 8 million
tonnes carbon per year (MtC / y), while the total human attribution case refers to all relevant human activities that have been measured and used in climate assessment model scenarios that influence climate change.
The Intergovernmental Panel on Climate Change in 2013 estimated that cumulative carbon dioxide emissions from fossil fuels and
cement production — from 1750 to 2011 — was about 365 billion metric
tonnes as carbon (GtC), with another 180 GtC from deforestation and agriculture.
According to the trillionthtonne.org website, humans have already emitted 561 billion
tonnes of carbon from fossil fuels,
cement production and land use changes.
In 2010, emissions from fossil fuel burning,
production of
cement, forest clearance and other factors, reached a record 10 billion
tonnes.
