Climate Action Q&A #1

This Little Piggy went to market…

Q: How fast should Little Piggy go when driving to the market?

——

Plot of CO2 emissions at actual speeds compared to those at 100 kph

A: No faster than 80 Km per hour.

For each one kilometre we travel at 10 kph below our open road speed limit (of 100 kph), we avoid dumping around 0.03 KG of CO2 emissions to the atmosphere.   

That does not sound very much, but with 3.8 million light vehicles*** in the New Zealand fleet travelling at total of 22,208 million km at open road speeds***, that represents a total of 651 KT CO2/year, or around 4.4% of the transport sector emissions.  Step the speed reduction up to 20kph, the emissions reductions would total 1,220 KT CO2/year which equates to around 8.2% of the transport emissions.

This series of posts is based around a resource prepared by Anglicans CAN for an Expo organised by Community Networks Franklin

Held at the Pukekohe Town Hall on Wednesday 29th May, the Anglican Climate Action Network was represented with a stand covering carbon budgets presented in a Q&A style.  This is the fifth of five posts.

Here’s five questions (and the answers) that the Anglican Climate Action Network (Anglicans CAN) are asked at climate action events.  

The answers are detailed and given for parents to explain to their children. 

The questions are set in the context of a little ditty told by parents to their children across many past generations, and future ones too – I hope.

The answers are determined from the Sustainable Anglicans Carbon Footprint Calculator.  For more information, call John on 021 46 36 86.
