Green loans – what exactly are they?


If you’re looking to reduce your footprint on the planet, but need some financial support to get there, you may choose to consider a green loan. We take a look at what green loans are, which financial institutions are offering them, and how they compare to other types of loans on the market.

We all know there are many things we can do at a personal level to help reduce our carbon emissions or reliance on the grid. But whether you are installing energy-efficient products in the home or upgrading to an electric vehicle, these green moves can come with a heavy price tag. Ideally, we would save up to make the purchase outright. But if that isn’t an option and you would like to make an environmentally conscious change sooner, a product you could think about is a green loan. And on average lenders are offering lower interest rated to consumers who want to put their credit towards ‘green products’, Canstar research shows.

What is a green loan?

A green loan is a type of credit offered by a financial institution to a customer on the basis that they use that money for something the lender considers to be environmentally friendly.

For example:

  • unsecured personal loans that can be used to purchase certain green products for your home. 
  • car loans used to purchase a more environmentally friendly vehicle, such as electric or hybrid
  • green home loans are also being introduced to the marketplace.

What can a green loan be used for?

The types of products you can purchase using a green loan may vary between lenders, but in general it can be used to purchase products that are more efficient in energy or water usage, reduce your reliance on the grid or reduce pollution. It is a good idea to ask your lender directly to determine whether the purchase you have in mind qualifies for a green loan. For example, the product may need to meet a particular star rating in energy efficiency.

Some products that you may be able to purchase using a green loan include:

  • Solar panels, hot water systems, pool heater or battery systems
  • “Green” or eco-friendly vehicle
  • Double glazing for windows or external awnings
  • Water tanks
  • Insulation
  • Grey water treatment system
  • Energy-efficient appliances and white goods
  • Energy-efficient electric heaters or split system, evaporative cooler or energy-efficient air conditioner
  • Home ventilation

How do green loans stack up against other loans?

Lenders say that they offer green loans as an incentive for consumers to switch to more efficient and environmentally friendly products. Often, the interest rates on green loans are lower than a standard personal or car loan.

For example, based on Canstar’s database, the average interest rates and fees for these loans compared to standard personal and car loans are shown below.

Other upfront and/or ongoing fees may apply.

One complication with this product type is that the loan can only be used for approved purchases. So, for example, if you are doing a renovation, you would only be able to use some green loans for the components of the renovation that are “green”. You may end up requiring a separate loan for the remainder of the work. Additionally, there are fewer lenders who offer green loans compared to personal loans, which means your options are more limited.

Who is eligible for a green loan?

Beyond the purpose of the loan, eligibility criteria for green loans are typically similar to other credit products. When applying, the lender will consider factors such as your income, your credit history (and credit score), whether you are an Australian citizen/resident or if you have filed for bankruptcy. You will likely need to supply the lender with your personal details including address and phone number, and evidence of your income, employment status, assets and debts as well as information on what you intend to use the loan for. Using that information, the lender will decide whether to approve the loan and, in some cases, what interest rate or other variable conditions will apply based on your particular circumstances.
