At Glower, sustainability isn’t just a goal, it’s our mission. In September alone, our customers helped us save 5,912 tonnes of CO₂ through energy-efficient solutions like heat pumps, air conditioners, solar batteries and solar panels.
It is equivalent to taking over 1,300 cars off the road for a year, planting 98,500 trees, or powering 1,100 Australian homes for a year.
But what does that number mean in the bigger picture of Australia’s carbon footprint and global emissions? Let’s answer some key questions.

How much CO₂ does Australia have?
Australia emits around 400 million tonnes of CO₂ each year. While this might sound small compared to global giants, on a per capita basis, Australians are among the highest emitters in the world.
That’s why every step towards energy efficiency, whether it’s installing solar panels or upgrading to heat pumps, makes a measurable difference. Our September savings of 5,912 tonnes of CO₂ show how small actions add up to big impact.
What is the largest source of CO₂ emissions?
The largest source of CO₂ emissions in Australia is electricity generation, particularly from coal-fired power plants. Transport and industry follow closely behind.
By switching to renewable energy sources and improving home energy efficiency, households can cut down their reliance on fossil-fuelled electricity and directly reduce their carbon footprint.
Which country is the biggest polluter in the world?
Globally, China is the biggest emitter of CO₂, followed by the United States and India. Together, these countries contribute more than half of all global emissions.
Australia, while smaller in size, still plays a critical role. By adopting sustainable living practices and energy-efficient technologies, we can set an example and push towards a cleaner, greener future.
Which country has the lowest carbon footprint?
Many small island nations such as Tuvalu or Vanuatu have some of the lowest carbon footprints in the world. They emit very little CO₂ but are among the most vulnerable to the impacts of climate change, such as rising sea levels.
This highlights the global responsibility: cutting emissions in Australia can help protect communities worldwide.
Where does Australia rank in global warming?

Australia is considered a high per-capita emitter and is particularly vulnerable to climate impacts, think bushfires, droughts, and heatwaves. According to international rankings, Australia has one of the highest per-person carbon footprints globally.
That’s why energy efficiency and carbon savings matter more than ever. By saving 5,912 tonnes of CO₂ in just one month, our customers proved that sustainable choices can help shift these rankings.
The Importance of Energy Efficiency
Improving energy efficiency is one of the most effective ways to reduce your carbon footprint. It lowers your energy bills, reduces reliance on fossil fuels, and cuts greenhouse gas emissions.
At Glower, we see energy efficiency not just as a trend but as the foundation of a sustainable future.
Most effective ways to reduce carbon footprint as a homeowner

If you’re looking to make a difference at home, here are some practical tips to improve your home’s energy efficiency:
- 🌞 Install solar panels and a battery to power your home with renewable energy.
- ❄️ Upgrade to energy-efficient heat pumps and air conditioners.
- 💡 Switch to LED lighting and smart appliances.
- 🏠 Improve insulation and sealing to reduce heating/cooling needs.
- 🚴♂️ Choose sustainable living habits, like reducing car use and saving water.
Available technologies and solutions to become energy efficient
Today, Australian households have access to a range of technologies:
- Solar panels and batteries to generate and store clean electricity.
- Heat pump hot water systems that use less energy than conventional systems.
- Multi-split and ducted air conditioners designed for both comfort and efficiency.
💡💵 These solutions are supported by government rebates, making them more affordable than ever.
Sustainable living with renewable energy sources
Solar panels remain one of the most powerful tools to cut emissions. They not only reduce your electricity bill but also help build long-term energy independence.
Combined with heat pumps and efficient air conditioning, solar creates a complete sustainable living solution.
