Carbon Estimates
As part of our journey planning service we provide an estimate of the CO2 emissions savings that would be made by taking the suggested public transport option instead of driving. Our calculations are estimates, as all distances involved are not exact—they are meant as a guide. We also assume zero carbon emissions for walking.
An example carbon saving estimate.
Carbon emission figures are provided by our carbon management partner Accuvio. The table below outlines the figures used in our calculations and their sources.
| Mode | g CO2 per passenger km | Source |
|---|---|---|
| Driving* | 155 | SEI 2008 |
| Dublin Bus | 77 | Dublin Bus 2006 |
| LUAS | 49.9 | RPA / Veolia Transport 2010 |
| DART** | 44.3 | Irish Rail 2006 |
- *
- Driving emissions are based on a singly-occupied petrol car, with a 1.21–1.5 litre engine.
- **
- DART emissions are estimated as diesel intercity/commuter train.
Accuvio provide a full suite of carbon management business support, from carbon accounting, energy monitoring, energy and emissions reduction, to carbon abatement (carbon offsets) from approved certified sources.
