What does the CO2 estimates feature do in a nutshell?
When we calculate a route, we can estimate the CO2 emissions using published (often government) standards where available. These figures can only be used as a guide as CO2 emissions are abstract.
Why are CO2 estimates abstract?
- Generate virtually the same CO2 emissions whether it’s empty or it carries 5 passengers.
- Does that mean passengers travelling on a full bus use less CO2 than those on an almost-empty bus because it’s shared across more people? What happens when it’s empty?
- Should passengers be penalised when the bus isn’t full or should full capacity be assumed to calculate?
- This is only an average because CO2 emissions for cars vary significantly
- Variances occur when driving a big or small car or an old or new one
- The driver also impacts this – steady drivers, fast drivers and less confident ones
- Levels of traffic, stopping and starting, using air con and numerous other factors play a part
- Electric Bikes
- Different trains emit different levels of CO2 emissions
- Type of ferry and other modes
Why use it?
- To give searchers a rough guide of how their journey is impacting the environment
- To set carbon emission reduction challenges
- To increase your customer awareness of CO2 emissions and deliver a green product
