An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from ...
In 2016 world gross carbon dioxide emissions from coal usage were 14.5 gigatonnes. [158] For every megawatt-hour generated, coal-fired electric power generation emits around a tonne of carbon dioxide, which is double the approximately 500 kg of carbon dioxide released by a natural gas-fired electric plant. [159]
Carbon footprints are usually reported in tonnes of emissions (CO 2-equivalent) per unit of comparison. Such units can be for example tonnes CO 2-eq per year, per kilogram of protein for consumption, per kilometer travelled, per piece of clothing and so forth. A product's carbon footprint includes the emissions for the entire life cycle.
Bełchatów is the fifth largest coal-fired power plant in the world. [8] According to estimates, in 2018, it emitted 37.6 million tons of carbon dioxide, more than any other power station, with relative emissions estimated at 1.756 kg per kWh. The plant releases more carbon dioxide each year than the entirety of Switzerland. [9] [10]
The plant's low CO 2 emissions per electric output, compared to other coal fired plants, were attributable to a relatively low heat rate combined with exclusive use of bituminous coal, which creates less CO 2 per heat output than other types of coal. [29] [30] [31] Mercury emissions in 2011 were 586 pounds (266 kg) or 3.4 pounds per 10 12 Btu ...

Coal is the largest contributor to the human-made increase of carbon dioxide in Earth's atmosphere. There are severe health effects caused by burning coal. [2] [3] [4] Worldwide 25 people die early for each terawatt hour of electricity generated by coal, around a thousand times more than nuclear or solar. [5]
