Aucklander's carbon footprint compared to Londoner's...

Did you know:


London Vs. Auckland transport CO2 emissions: 2006 comparison




Population
Total emissions
Per capita total emissions
Transport emissions
Per capita transport emissions
% transport emissions of total emissions


London*

7.3 million
44.3 MtCO2
6,068 kg/person
9.6 MtCO2
1,315 kg/person
22%


Auckland**

1.2 million
11.93 MtCO2
9,941 kg/person
5.14 MtCO2
4,283 kg/person
43%


* Halcrow Group et al, 2009 VIBAT Stage 1 Report, p.58 (see:www.vibat.org)

** ARC Modelling

So. Aucklanders are responsible - on average - for THREE TIMES more transport CO2 emissions compared to Londoners, due to our higher travel demands and greater transport energy use. Interestingly, London's relatively low transport carbon footprint, the UK Government and Greater London Authority are jointly getting on with a set of policy initiatives to reduce this carbon demand (due to transport) by 60% by 2030.

The UK is taking CO2 emissions - and transport energy efficiency - very seriously.

I wonder when our Government will get round to translating its 10 - 20% CO2 reductions by 2020 target it has commited NZ to at Copenhagen, into policies and strategies that will reduce transport energy in Auckland....

And I wonder what we need to do as a region to ensure that our new Regional Land Transport Strategy also tackles this imperative....

But, hey ho, even if we do have a great little regionally agreed RLTS, Transport Minister Joyce doesn't seem to feel any need to give it any attention anyway. He's just advanced the biggest road building program NZ has seen. Totally in conflict with the current RLTS. Maybe he thinks it's a sign of economic strength and power to push Auckland's transport related CO2 emissions way up, so that then we can skite internationally that we emit FIVE TIMES more CO2 per capita getting around than our London mates. Now there's a claim to fame....

How sustainable is ferry travel....?

This is an interesting one. The issue of how "carbon hungry" ferries are first came to my attention when I was asking the former CEO of Veolia (Chris White), how expensive it was to run our diesel trains. I did some research and found the following:


Cost of fuel to run Auckland's public transport. % of mode operating costs.


Mode

Rail
Bus
Ferry



% of Operating Cost

3%
11%
30%



You can appreciate how much it costs to push a ferry through the sea, compared to the low rolling friction of a train, with steel wheels running on steel rails whose gradients are usually not more than 2%. But a train is a very heavy thing - when it's full of passengers the total weight hardly changes.

Now we have a "free weeks ferry and bus" ticket being offered by ARTA and Fullers. This is good. But it is helpful to understand what we are promoting here....

There is a fantastic link I recommend if you are interested in growth strategy and intensification and stuff. It's a blog: Agenda 21, Auckland, Intensification, and Sustainable Urban Development, by Manish Udar. You can find it here:
http://sustainability.rediffiland.com/blogs/2007/05/21/Agenda-21-Auckland-Intensification-and-3.html

Here's a quote:
".....Public transport is an area of considerable energy wastage. It is quite commonly believed that commuter trains are the most sustainable form of urban transport, followed by fully occupied buses followed by fully occupied cars and that the least sustainable form of urban transport is an empty commuter train followed by an empty bus followed by a single occupancy car. But these common assumptions are not borne out by facts, if energy consumption and CO2 emissions for various transport modes are examined....As is shown by the following table, urban transport also contributes heavily to the greenhouse effect if it consists of petrol, diesel or gas driven buses, or if coal or gas is used in the production of electrical energy to power public transport trains. It also shows that vehicles with a high occupancy rate are less likely to contribute to the greenhouse effect. If a lot of people are packed together in a given space, they are more likely to be able to find a group of persons to occupy their vehicle to its optimum capacity. This seems to suggest that an intensified city will lead to lower greenhouse emissions. Whether this is borne out by experience needs to be examined....."

That old Jet Raider ferry is seriously hungry.
Because those partly filled trips really chew through the diesel.
Wonder how the Kea does?
