How to actually reduce your carbon footprint - Postpone big outputs

We make decisions about big infrequent emissions all the time. Taking an overseas holiday, pouring a large concrete slab, buying a new car. A simple - even banal - way to reduce emissions in a given time period is to not emit in that time period. In other words, to postpone a project and thus the big emission associated with it.

In "How Bad Are Bananas" Mike Berners-Lee proposes a 10-tonne annual CO2 'budget' per person. I think this is a good starting point for a sustainable first-world lifestyle, but will probably not be enough in the end.

Here are some examples of postponed emissions.

• A new car is more or less a 1-tonne embedded carbon purchase. If you wait another year before you upgrade your car, you postpone the carbon emission to manufacture not your car, but the one that replaces your new car in the sales yard.
• An overseas trip (from Australia) is more or less a 1-ton per capita emission. How about you go camping a couple of hours drive out of the city this year, and schedule that trip to Europe for next year or the year after. You will postpone that emission. 
• A concrete slab is, conveniently enough for counting, about a ton of CO2 per room. Putting your new house extension on posts instead of a slab, or hunting around for low CO2 emissions concrete (hey check out the Roman technology here!)
  The rest of the new room is about a ton as well. How about you let the kids share a bedroom for another year, and postpone the whole renovation. Or the new kitchen. Or the landscaping & new swimming pool. Renovating in timber is not simple because it's a carbon cost and a carbon sink.
  But if there are manufactured surfaces (like plaster) or manufactured appliances, you can bet on at least 1 tonne. 
• Professionally, can you encourage your company to get another year out of that large appliance for your corporation (the big printer, the server rack, the factory air conditioner, the big industrial pump/machinery thingo)? Can you persist in the existing premises for just one more year without designing a new purpose-built thing in a concrete industrial park?
• Can you get the fleet cars to be used for 4 years instead of 3?
• Can you think of any other 1-tonne CO2 expenditures which can be postponed without much fuss? You might surprise yourself.

Simple, obvious, and astoundingly easy (inaction is often very easy). Plus, it may have unexpected benefits for your personal or organisational financial outgoings as well.
