# You asked: How much co2 does a tonne of coal produce?

Contents

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 of coal?

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.

212 Kg CO2

## How many tonnes of co2 does UK produce?

In 2019, UK net emissions of carbon dioxide were provisionally estimated to be 351.5 million tonnes (Mt), 3.9 per cent lower than 2018 (365.7 Mt). Carbon dioxide (CO2) is the main greenhouse gas, accounting for 81 per cent of total UK greenhouse gas emissions in 2019.

## How much co2 does a pound of coal produce?

For example, coal with a carbon content of 78 percent and a heating value of 14,000 Btu per pound emits about 204.3 pounds of carbon dioxide per million Btu when completely burned.

## How much co2 is produced per kg of coal?

## 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 does concrete produce?

In 2018 the standardised mix value was 72.1 kg CO2/tonne for concrete. For concrete + reinforcement the CO2 emissions are 80.2 kg CO2/tonne – this is a reduction of 15% (from 94.7kg CO2/tonne) since the first year of reporting in 2009.

## 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. As businesses, we need to do more to be greener, but that doesn’t mean we should operate in the red.

## 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).

## What is the biggest polluter in the UK?

Transport most polluting sector as UK greenhouse gas emissions fall. The latest figures show UK greenhouse gas emissions fell 2 per cent in 2018 but the transport sector, which is the biggest polluter, has seen little improvement.

## What is the biggest cause of co2 emissions?

Global Emissions by Gas

• Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2. …
• Methane (CH4): Agricultural activities, waste management, energy use, and biomass burning all contribute to CH4 emissions.

## How much does the UK contribute to global warming?

In 2016, the UK consumed the equivalent of an estimated total of 784 million tonnes of carbon dioxide emissions – more than one-and-a-half times the 468 million tonnes from territorial emissions alone.
