We care about our environment and are proud to be 'tree huggers'.

Hugging trees?

We love trees — they clean the air we breathe, filter the water we drink, support over 80% of the world’s terrestrial biodiversity, regulate climate, and help create healthier, more resilient environments.
But we don’t just like trees — we act on it.
We don’t aim to be carbon neutral; we aim to operate beyond it. As part of this, we fund the planting of trees through Carbon Positive Australia and offset our vehicles and flights as part of how we operate.

Donated native trees

2022

Evoegy was founded in June 2019. By the end of our first year, we had already funded the planting of 141 native trees through Carbon Positive Australia.
These trees began offsetting between 0.38 and 1.13 tonnes of CO₂e per year, depending on environmental conditions.
That early impact set the direction — we wanted to see how quickly we could reach carbon neutrality, and whether we could go beyond it.

2023

By November 2020, we had effectively achieved carbon neutrality with 665 trees planted under optimal conditions.
By the end of 2022, we had funded a further 1,501 trees — bringing the total to 2,166.
As of November 2023, that number had grown to 2,898 trees, offsetting between approximately 7.7 and 23.2 tonnes of CO₂e per year depending on conditions.
This forms the baseline of how we operate — and we continue to build on it as we grow.

'Back of a beer mat' calculation

We approached this as engineers — by understanding the numbers. Working with ecologists and Carbon Positive Australia, we looked at how carbon uptake is measured. Rather than per tree, it is calculated per hectare and depends on species, planting density, rainfall, and soil quality.
In high-rainfall areas with good soil, it can take as few as 3–5 trees over 25 years to remove 1 tonne of CO₂. In lower rainfall areas with poorer soil, this can increase to around 15 trees.
We took a conservative approach. We based our calculations on 5 trees per tonne in optimal conditions and 15 trees per tonne in less favourable environments. This equates to approximately 0.008 and 0.003 tonnes of CO₂e per tree per year, respectively.
By choosing conservative assumptions, we avoided overstating our impact — and ensured we would always be doing more, not less.

'high rain, good soil'

'low rain, poor soil'

We ran a simple ‘back of a beer mat’ model to estimate our impact, based on CO₂ emissions per consultant, adjusted for their geographical location.
We calculated emissions relative to working time using consultant hours per year, with other major sources accounted for through Carbon Positive Australia’s offset programme.
So, does it add up? Yes
We reached beyond carbon neutrality on average by June 2021 with 1,115 trees planted. By October 2022, we had achieved carbon neutrality even under low rainfall and poor soil conditions.
Today, Evoegy operates approximately 17.9 tonnes of CO₂e per year beyond carbon neutral under optimal conditions, and 2.5 tonnes per year beyond carbon neutral under conservative conditions.
