About the household

The Cavdarski family – Sheridan, Phil and their son – live in a townhouse in North Brisbane. The young family were determined to give the Brisbane Carbon Challenge their best shot and undertook actions across energy, transport and waste to reduce their carbon emissions. Being renters, the Cavdarskis had limitations to work with. Still, they managed to reduce their carbon footprint by an impressive 78%.

‘The more people that reduce their impact, the better off we all are. Even if it’s just one step at a time.’

Successes

Returning to cycling

Transport is the biggest source of carbon emissions for the average Brisbane household. Yet, it’s often the hardest emissions source for households to change or reduce, due to lifestyle factors that make it hard to get around without a car. However, this didn’t stop the Cavdarskis, who replaced their daily car commutes with bike riding. Sheridan notes, “We hadn’t been [bicycle] riding much since our baby was born, but since starting to ride to work, it reignited that passion, and now we ride almost every day for exercise as well as transport. Not only have we reduced our emissions [and] saved on petrol costs, but we also enjoy the exercise and health benefits we get from it.”

With petrol prices as high as they are, this switch to cycling will save the Cavdarskis more than $350 a year on fuel costs.

Inspiring a townhouse composting system

Living in a townhouse complex, the Cavdarskis saw an opportunity to help their neighbours reduce their food waste and allowed them access to their compost solution. Sheridan explains how they achieved this: “We put our compost tumbler just inside our gate and put a sign up with step-by-step instructions in case they were unsure. We used a sticker to identify which side they needed to add to.”

And now, not only have Sheridan, Philip and their son helped their neighbours reduce their food waste and corresponding greenhouse gas emissions, but their townhouse community compost system is giving back to their neighbours too: “We have also offered the mature compost and soil back to the [other] houses if they want to plant or put it into their courtyards.”

Challenges

Accessing renewable energy while renting

Switching to renewable energy by installing a solar power system is an obvious choice for Brisbane households looking to reduce energy emissions. However, this option wasn’t available to the Cavdarskis as they rent their home. Instead, the Cavdarskis switched to a 100% GreenPower plan, meaning their energy provider buys independently accredited renewable energy from renewable sources to match their household electricity consumption.

Home energy use was responsible for 56% of the Cavdarskis’ household carbon footprint at the start of the Brisbane Carbon Challenge. After making the switch to GreenPower, plus other small behaviour changes and investments, their energy emissions are now less than 1% of their total carbon footprint.

The Cavdarski’s top tip:

“Keep your compost caddy in the fridge and it doesn’t smell! Then you can add it to the compost tumbler outside when it’s full so you don’t have flies or a smelly bin on your counter.”

The Cavdarski’s low carbon action plan:

  • Replacing vehicle use with active transport (cycling).
  • Using E10 instead of petrol.
  • Purchased 100% GreenPower.
  • Using a fan instead of air conditioner.
  • Switching off lights when not in use.
  • Upgrading lights to LED.
  • Switching off appliances at the wall when not in use.
  • Installing low-flow shower head.
  • Reducing food waste.
  • Composting food waste.
  • Using reusable nappies.
