Buy and grow local food
The way we shop and the food we eat can have a big impact on our household footprint. Choosing New Zealand made products and locally grown food will cut emissions and support local jobs. Growing food at home and having a plant-rich diet can help even more and will shrink your shopping bills too.

- Grow food at home. Edible Christchurch(external link)(external link) and the Canterbury Horticultural Society(external link)(external link) can help with gardening tips.
- Gather fruit and nuts from trees growing in public places. To encourage food foraging the Council has a mapped edible trees(external link) growing in public places throughout the city.
