How we calculate your rewards

By Paul Baxter, 19th September 2023

Our exclusive rewards portal is packed with discounts, offers and freebies.

We select brands who have a similar ethos to us, in addition to offering discounts on some household names to help you reduce your day-to-day spend. You can use your Leaves to buy eGift cards for supermarkets and other retailers.

Some of these brands have a strong environmental ethos and we love working with these companies. Others may be less environmentally focussed, but we include them to offer you discounts at places where you may already shop for your groceries and other daily household items.

How we calculate your rewards based on your driving emissions

It makes sense that if you drive less, then your driving would emit less carbon CO₂.

However, even if you drive minimal miles, your driving habits can also make a difference how much carbon your driving could produce.

For example:

Someone driving 7,000 miles each year, who sticks to the speed limit, who regularly maintains their car, and who doesn't take corners too fast, will likely emit less CO₂.

On the other hand, a driver (also only driving 7,000 miles each year) who exceeds the speed limit, accelerates hard when setting off, and drives round corners too quickly, will likely emit a significantly higher volume of CO₂.

Both drivers only cover 7,000 miles, but their habits can mean a difference between a high Green Driving Score of between 81-100 and a low green driving score of 50 and below.

At The Green Insurer we take the distance covered as well as the driver's habits into account when we calculate our customers rewards.

The table below shows how your drive could affect your green driving score and your CO₂ emissions.

This example is based on a driver who expects to drive 12,000 miles each year (1,000 average per month) and is based on the average CO₂ emissions from, our list of vehicles we get from the DVLA.

If the driver's driving habits, which are tracked in our App, are at an average score of 66 – 70, their emissions will have totalled 2.6 tonnes over the year.

If they had driven more carefully and reduced the number of miles driven, they could have reduced their CO₂ emissions by more than half (or 1.39 tonnes per year). This would have earned them more reward Leaves too.

To halve their CO₂ emissions, they would have needed to reduce their miles from 12k pa to 7k pa and have a driving score of over 91.

According to the RAC, as of March 2023 there were 33.48 million cars in the UK. If each car covered 12,000 miles a year and followed similar driving habits to the example shown, they could conceivably emit a total of 86.5 million tonnes of carbon in one year.
