Million tonnes of CO2
Outbound flights only 2.53
Apply 1.9 RFI* 4.80
Surface Access 0.12
On-site activities 0.04
Grand Total 4.96
*RFI = Radiative forcing index - Latest IPCC advice on climate change impact of air travel is 1.9 X CO2. This excludes the impact on cirrus cloud formation.

Stansted CO2 Emissions
Think Global – Act Local SSE Community Conference 2007
Switching off all street lights in Essex all the time would save
19,000 tonnes CO2 p.a.
Equates to only 1 day full
use of the Stansted runway

Hadyard Hill is the largest wind farm in the UK today and saves
300,000 tonnes CO2 p.a.
...but this equates to only 16 days full use of the Stansted runway

Save 4.5m tonnes of CO2 p.a.
Equates to only 235 days full use of the Stansted runway

Full use of the Stansted runway
would eliminate the savings from
350 million low energy light bulbs

A year’s driving in a typical family
car will produce 3 tonnes of CO2
Full use of the Stansted runway
would produce as much CO2 as
2.3 million typical family cars
On the Road
Think Global – Act Local SSE Community Conference 2007
Full use of the Stansted runway
would produce as much CO2 as
1.4 million family homes
An average UK family home produces 5 tonnes of CO2 p.a.

To offset the CO2 emissions from full use of the Stansted
runway we would need to ...
Recap

... build 23 new wind farms each as big as Hadyard Hill – the UK’s largest covering 12 square kms
Either:

But that’s not enough ...
• We need to dramatically reduce our CO2 emissions
• UK target is 60% reduction by 2050
• Needs to be achieved globally to stabilise atmospheric CO2 levels

• All these comparisons are simply for full use of the Stansted runway
• For a second runway the numbers would be far more worrying
Remember!
