Closing in on Net Zero by 2030

As a nature organisation, it’s essential that we cut our greenhouse gas emissions. Our aim is to get as close to net zero as possible by 2030. This means drastically reducing the fossil fuels we use directly and indirectly in our operations. Our plan considers everything from electricity and transport to tools and waste.

What it means to reach Net Zero

To become a Net Zero organisation by 2030 we are reducing our greenhouse gas emissions by 158t CO2e and will offset any residual emissions.

‘Net Zero’ refers to a state where the greenhouse gases going into the atmosphere are balanced by the gases being removed from it.

What we look at

In considering our strategy for cutting emissions, we looked at:

  • Travel – for business, commuting of staff and volunteers, use of Trust vehicles for operations
  • sighting
    Our activities and premises – including emissions from staff working from home
  • protect
    The waste we produce and how it’s processed
  • fundraising
    The things we buy – the energy consumed by producing and transporting them

Habitat creation at Pevensey Levels nature reserve means, in time, the site will also store more carbon, helping to achieve our Net Zero target by optimising the ability of our nature reserves to mitigate the impacts of climate change.

How are we cutting our emissions?

We looked at the areas with the greatest carbon emissions and thought about what practical steps we could take to reduce those. These steps have become our pathway to reach our carbon-cutting goals. Below are some of the key ones. Some of them have been completed, others are planned:

Switched to having more electric or hybrid vans and cars

Switched to a renewable electricity supplier for Rye Harbour Discovery Centre

Installed Electric Vehicle (EV) chargers at Woods Mill and Southerham Farm

Moved our HQ from Woods Mill, Henfield to The Keep, Falmer

Installed 24 solar panels on Southerham Farm buildings

Added 66 more solar panels to Rye Harbour Discovery Centre, bringing the total to 89

Install solar panels or wind turbines if viable on other reserves

Trialling Hydrotreated Vegetable Oil (HVO) for some of our off-road fleet

Switching from petrol-powered to battery-powered tools wherever possible

Put in places policies to support car-sharing, cycling and use of public transport

Encourage hybrid working and staff using renewable energy suppliers at home

Moving our HQ from Woods Mill nature reserve to The Keep at Falmer

Although having our HQ on one of our reserves was ideal for our nature-loving staff, it was less ideal for carbon emissions. Commuting to Woods Mill was only really viable by car for most of our staff.

In late 2025, we moved our HQ to The Keep in Falmer, on the outskirts of Brighton. The move was a key part of our 2030 net zero strategy to reduce carbon emissions. This modern building has a BREEAM rating of ‘Excellent’ and  is:

  • Easily accessible by public transport
  • Uses solar energy
  • Harvests rainwater

Livestock emissions

The cow in the room: or rather the cows and the sheep in our reserves

Grazing herds of sheep and cattle on our reserves is critical to how we manage and restore our nature reserves. In the past, natural wild herbivores, like deer, would have done their task: tearing up vegetation, fertilising soil with their dung, disturbing the soil, causing seeds to germinate and pools of water to form. All of this helps to sustain diverse thriving habitats and reinvigorate degraded land.

But we can’t ignore the environmental impact of animal agriculture, including carbon emissions. In our 2030 goal, we have included all aspects of the operation of herds in our calculations – such as emissions from vehicle fuel, water use and waste – but not the emissions of the animals themselves.

We’ve done this because at the moment, we don’t currently have a practical, viable alternative we can implement on our reserves that would achieve the same environmental goals as conservation grazing. Realistically, offsetting the residual emissions of the animals themselves would be more than the Trust can afford. We’ll keep working to find alternative nature-based solutions that could help us change things in the future.

FAQs

How will the Trust offset residual emissions?

We will be exploring options for the possible deployment of solar or wind power generation on selected nature reserves, where it would not conflict with our conservation aims.

What kinds of vehicles does the Trust operate?

We operate a variety of vehicles according to our requirements: 

  • Fully electric and mild-hybrid cars and vans, for  visiting sites and premises
  • An electric minibus, for transporting volunteer work parties to sites
  • Diesel trucks, tractors and all terrain vehicles and petrol quad bikes, for work on out nature reserves

Why does the Trust still use diesel or petrol vehicles?

There are some vehicles, such as our 4×4 trucks and tractors used for managing our nature reserves, for which there are currently no viable electric alternatives.  We aim to put these in place as they become available, but in the meantime, we have begun improving the situation by using hydrotreated vegetable oil (HVO), a greener alternative to diesel fuel, that can lead to a reduction greenhouse gas emissions of up to 90% and gives a significant reduction in particulate emissions.

Why can’t the Trust use deer instead of cattle or sheep for conservation grazing?

Deer don’t eat in the same way as sheep and cattle, and we need the diversity of different herbivores to give the varied vegetation structure we are looking for. Deer also require significantly more infrastructure to keep them on reserves and this would not be practicable.
