Determining carbon emissions from flights:
The top 5 overseas destinations for UK holiday-makers are Spain, France, USA, Italy and Greece.
According to COIN's (Climate Outreach and Information Network) study of online calculators, one of the best calculators for air travel is http://chooseclimate.org/flying
.
Using this calculator to determine carbon emissions for a return trip from London to each of the country's capitals (except for the USA where New York is a more popular holiday destination)
, results in the following emissions:
Spain - 1143 kg
France - 525 kg
USA - 3857 kg
Italy - 1226 kg
Greece - 1874 kg
Taking an average of these carbon emissions = 8625/5 = 1725 kg
Determining carbon emissions from domestic breaks:
Domestic holidays account for 3 out of every 4 holidays, and according to National Statistics, the average distance travelled on a long distance trip in the UK is 61.3 miles, so a return trip will be 122.6 miles.
Carbon emissions associated with domestic travel by car:
0.207 x 122.6 x 1.61 = 40.86 kg CO2
(where 0.207 = kg CO2 produced by a car of unknown fuel type per km
, and multiplying by 1.61 converts miles into km)
So calculating a weighted average of flights and domestic breaks:
3/4 x 40.86 = 30.64 kg
1/4 x 1725 = 431.25 kg
30.64 + 431.25 = 462 kg CO2 approx
In comparison, if an individual were to holiday locally instead, assuming travel within a 30 mile radius, by public transport, this would result in carbon emissions of around 5 kg
= 457 kg CO2 approx saved by taking a break in your local area.
