Stansted CO2 Emissions

Switching off all street lights in Essex all the time would save

19,000 tonnes CO2 p.a.

Equates to only 1 day full

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

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

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

Think Global – Act Local SSE Community Conference 2007

• All these comparisons are simply for full use of the Stansted runway

• For a second runway the numbers would be far more worrying

Remember!

Think Global – Act Local SSE Community Conference 2007

• Climate change is now inevitable

• The best we can do is to prevent catastrophic climate change

• Everyone must play a part

• Aviation/BAA cannot be exempt
