Let us know if you have any ideas to help. We’ll add them. Go team. Thanks for caring. You’re awesome.


Carbon emissions are a big part of Treading Lightly. Jamie & Nick attempted to live within 2 tonnes of carbon emissions each. Settling on 2 tonnes was based on a average of multiple sources. Some sources suggest as little as 1 tonne p/person p/year up to 3 tonnes p/person p/year.

Sources supporting 1 tonne p/person (from Google Scholar):

Sources supporting 3 tonne p/person (great source of info and ideas in any case):

Book: How Bad Are Bananas? by Mike Berners-Lee

Book: How to Live a Low-Carbon Life by Chris Goodall

Interesting read:

We used (and continue to use) the search engine for the documentary. They use advertising revenue to plant trees.

For every 45 searches, 1 tree is planted = estimated 50 kg offset. Our 1700+ searches during our Treading Lightly year would make for a decent offset, but if we are going to be fair, it’s Ecosia’s offset, not ours. So we didn’t include it.


During the making of Treading Lightly, Jamie and Nick discovered the ecological footprint. This concept looks beyond carbon as a measure of human impact on the planet.

Earthships featured in the film for their unique approach to building with waste and recycled materials. More info on them below

Due to Jamie and Nick’s distance from most services, friends and the city, they purchased E-bikes to be a ‘middle way’ approach to transport. For more info on why, this article sums it up the best.

Food waste is bad for the environment. To see how bad, visit this food waste to methane calculator:

Food Waste Guide:

If you are looking to collect food waste for a charity, consumption or compost, this legislation might help:

Civil Liability Act 1936

It states in division 11A—Food donors and distributors 74A—Food donors and distributors

  • (1)  In this section, a reference to a food donor or distributor is a reference to a person who, acting without expectation of payment or other consideration and for a charitable or benevolent purpose, donates or distributes food with the intention that the consumer of the food would not have to pay for the food and to the agents or employees of such a person.
  • (2)  A food donor or distributor incurs no civil liability for loss of life or personal injury arising from consumption of the food donated or distributed.


What can be recycled in Australia will depends on your council. For Jamie and Nick, these websites were useful. Maybe they are for you too.

Recycling Disposal Guides are available for most councils online, you can search through your council website. Here’s Jamie and Nick’s.
