Coal’s most notorious byproduct is carbon dioxide (CO2). Every million BTUs released from burning coal releases an average of 208 pounds of CO2 (see note below). Since a ton of coal has 20.025 million BTUs, that means it creates 4,172 pounds of CO2 when it is burned.
How do you calculate co2 emissions from coal?
Pounds of coal burned
Carbon dioxide emissions per pound of coal were determined by multiplying heat content times the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to that of carbon (44/12).
How much co2 is produced per ton of steel?
The global iron and steel industry accounts for approximately 5% of total global CO2 emissions. On average, 1.9 tonnes of CO2 are emitted for every tonne of steel produced.
How much co2 is produced for each tonne of paper production?
212 Kg CO2
How much co2 is produced per ton of cement?
The reason one tonne of cement produces 1.25 tonnes of CO2 comes from two sources. First the limestone which is burned to make cement is more than twice the density of water and has to be heated to 1,450 degrees C, which uses a lot of fossil fuel, about . 75 tonnes per tonne of cement.
How much does coal contribute to global warming?
Coal is the single biggest contributor to anthropogenic climate change. The burning of coal is responsible for 46% of carbon dioxide emissions worldwide and accounts for 72% of total greenhouse gas (GHG) emissions from the electricity sector.
What fossil fuel produces the most co2?
Can steel be made without coal?
Now, nearly all new steel globally is produced using iron oxide and coking coal. Coking coal is usually bituminous-rank coal with special qualities that are needed in the blast furnace. While an increasing amount of steel is being recycled, there is currently no technology to make steel at scale without using coal.
How much co2 is produced per ton of stainless steel?
Can you make steel with renewable energy?
At present, the ultimate solution is considered to be ‘green’ steel, made with renewable hydrogen. … Just as thermal coal can be replaced with clean energy from renewables, we can use low-emissions steel manufacturing to phase out metallurgical coal.
How many trees are cut down for paper?
Out of the 17 billion cubic feet of trees deforested each year, over 60% are used to make paper. This deforestation is responsible for nearly a fifth of the world’s annual greenhouse gas emissions.
How does paper pollute the environment?
Nitrogen dioxide(NO) sulfur dioxide (SO) and carbon dioxide (CO) are emitted during paper manufacturing. All of them cause acid rain and CO is a major greenhouse gas that causes climate change. These toxic gases contribute to air pollution. … Deinking recycled paper pulp produces waste slurry which may go to landfill.
Does paper produce methane?
First, when paper is not recycled, 80% of it ends up in landfills. Decomposition of the paper in landfills produces methane, a greenhouse gas with 21 times the heat-trapping power of carbon dioxide (CO2).
Which industry contributes most to global warming?
- Transportation (28.2 percent of 2018 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions. …
- Electricity production (26.9 percent of 2018 greenhouse gas emissions) – Electricity production generates the second largest share of greenhouse gas emissions.
What is the largest co2 contributor?
What is the biggest co2 emitter?
In 2018, China was the biggest emitter of fossil fuel carbon dioxide (CO2) emissions. With a share of almost 30 percent of the world’s total CO2 emissions that year, this was almost twice the amount emitted by the second biggest emitter the United States.
