Flight emissions calculations: Google Docs June 2, 2010

Finally finished the spreadsheet which shows a sample day’s departures from Birmingham Airport and each flight’s average carbon emissions (calculated on travelmath.com which works on an assumption of a 65% load factor with 139 seats per flight). Obviously this is a rough estimate but from this, my initial calculation of the total emissions saved at Birmingham Airport during the ‘original’ UK air space ban is as follows:

Average daily carbon emissions = 27.94 tonnes

Number of days planes grounded (originally) = 6

Average total emissions saved = 27.94 x 6 = 167.64 tonnes

Hurray! : )

Finally got some figures to work with in my quest to map the emissions saved by flights being grounded at Birmingham Airport during the ash cloud (first-time round).

Again, Justine Hunt at the airport’s been really helpful and I’m going to visit the environment team on Friday…so hopefully more interesting stuff on the way for BRInvestigates…

Anyway…the rough figures so far (this whole project is very much a close ‘approximation’)…

  • The average number of flights in and out of Birmingham = 300 daily (over the six days, this is approx. 1800 flights cancelled)
  • Approximately 203 departures per day (sample from today, Wed 12th May)
  • Disregarding the type of aircraft, short and long-haul flights can be calculated using travelmath.com – which calculates the carbon emissions of each flight based on an assumption of a 65% load factor with 139 seats

As Justine pointed out, the only way to work out an average day’s flight emissions would be to take a sample from the departures board on the website (which would show short, long-haul and domestic flights) and calculate the approximate carbon output for each flight. I’ve started an Excel spreadsheet to organise and calculate this data and will attach it once completed.

Once I’ve finished the laborious task of using the calculator to estimate the total emissions from the day’s sample departures, this can then be multiplied by the six days (in which flights were grounded) to give an approximate idea of the total carbon emissions saved by flights being grounded at Birmingham Airport during the ‘first’ ash cloud incident.

 Then finally……….I will attempt to map the data. Getting there slowly….

Yep, that’s right – the one in Iceland that’s brought misery to thousands of stranded air passengers across Europe and caused UK airspace to close for 6 whole days. Well, the team at BRInvestigates have seen through the misery and thought GREAT! (well we didn’t exactly say that) What are we interested in? The environment. And what does the airspace closure mean for the environment? Less aviation emissions.

So what? Well as the winding path of Online Journalism continues to weave its complex web – we suddenly come face-to-face with another daunting and mind-boggling concept…….INTERACTIVITY….which I will tackle in another post.

So, in our quest to make our online journalism more interactive, we thought about creating some elements which represented data about the emissions saved during the airspace ban in other ways to writing an article. Mapping the flights that would normally have left the UK to Europe and showing the CO2 emissions that have been saved as a result of the ban would be one way of doing that.

Cue the pitiful efforts so far…..
