Comparison of Carbon Dioxide and Sulphur
Dioxide Emissions from Various Fuels
Carbon dioxide emission factors for delivered energy
in kilogrames of carbon dioxide per gigajoule (source: SAP 1998,
DETR)
| Fuel
| kg CO2
per GJ
| Calorific Value
GJ/tonne
|
| LPG (Propane) | 69
| 49.4 |
| Heating Oil | 75
| 46.2 |
| House Coal | 81
| 30.6 |
| Anthracite | 88
| 33.9 |
| Electricity | 142
|
|
Each thousand tonnes of LPG replaced by the following
fuels will result in increased emissions (for equivalent energy
input) of:—
| Fuel
| Increased CO2
(tonnes)
| Increased SO2
(tonnes)
|
| Heating Oil (Class Cl kerosene)
| 296.4
| 0.47 |
| Heating Oil (Class C2 kerosene)
| 296.4
| 3.89 |
| Gas Oil | 296.4
| 3.96 |
| House Coal | 592.8
|
|
| Anthracite | 938.6
|
|
| Electricity | 3606.2
|
|
Each thousand tonnes of the following fuels replaced
by LPG will result in reduced emissions (for equivalent energy
input) of:—
| Fuel
| Reduced CO2
(tonnes)
| Reduced SO2
(tonnes)
|
| Heating Oil (Class Cl kerosene)
| 277.2
| 0.44
|
| Heating Oil (Class C2 kerosene)
| 277.2
| 3.64
|
| Gas Oil | 272.4
| 3.64
|
| House Coal | 367.2
|
|
| Anthracite | 644.1

Gross calorific values of fuels from Digest of United
Kingdom Energy Statistics 1998, DTI, sulphur dioxide emissions
based on maximum sulphur content in BS4250 for propane, BS2869
for kerosene and gas oil.
