Sustainability at ZSL

As well as our extensive conservation field programmes and endangered species breeding work, ZSL is also working hard to improve the way we manage our Zoo sites to reduce negative environmental impacts and enhance ecological and social benefits.

At ZSL we are:

  • Reducing our energy and fuel consumption by installing new condensing boilers, installing energy efficient LED lighting, using electric vehicles on site and installing renewable energy systems.
  • Reducing the amount of water we use through improved management, fixing leaks and collecting rainwater into water butts and moats.
  • Reducing the amount of waste which is sent to landfill – less than 3% of our waste currently goes to landfill, and we are working on reducing this even further. We also recycle over 8 different waste streams including paper, plastic, oil and batteries.
  • Encouraging local wildlife to our site with woodland areas, ponds, logpiles and bird and bat nestboxes.
  • Demonstrating green ideas to visitors with signs around the site on how to protect the environment and conserve local wildlife.
  • Promoting Fairtrade, organic, local and seasonal products in our Zoo shops and cafes, including selling only sustainably sourced fish on site. 
  • Working towards ensuring that only sustainable palm oil is used in all products we purchase including food products, animal feedstuff and cleaning products.

Environmental Animal Exhibits

Many of our animal exhibits are built and run in ingenious ways that make them much less wasteful, minimising their environmental impact and their cost. We are developing new ideas all the time, such as a new rainwater harvesting system.

Managing Eco-Friendly Estates

One of the central ways in which ZSL practices sustainability is through the reduction of our electricity and water use and our waste production, which is all thanks to our estates managers. We have an ISO14001 standard Environmental Management System.

Considerate Retail & Catering

What we offer to our visitors at the Zoos needs to support ZSL's core conservation message. We select our stock for the gift shops very carefully, and source sustainable food locally for our on-site cafes. Some we even grow ourselves!

Horticulture and biodiversity

Part of Whipsnade Zoo is a Site of Special Scientific Interest (SSSI) approved by Natural England, but our horticulture team go even further in trying to improve onsite diversity, collect sustainable timber and compost, as well as growing our own browsing plants for the animals.
