Here at the Horniman Museum and Gardens, we're working hard to be as environmentally friendly as possible.

Read our Sustainability Policy by downloading the PDF below.

From improving energy efficiency inside, to recycling and composting outside, here are just a few of the ways we're getting greener.

  • We are a Green Flag venue and hold a Green Tourism Gold Award.
  • The Horniman Gardens are part of the Green Chain Walk, and are regularly visited by the Lewisham Healthy Walks group.
  • We take care to ensure that our Nature Trail – the oldest in London – and our Gardens are a haven for wildlife. We have bat boxes, birdhouses and bug hotels, as well as protected plant species such as mistletoe.
  • Around 97% of our Gardens waste is composted, and then reused in the Gardens.
  • Each year around 187,000 litres of water from the Aquarium’s water filters are re-used for watering the Gardens. This water is a waste product which can't be used in the aquarium due to impurities and sensitivity of the fish and corals, but it's perfect for the plants.
  • We have an on-site Ridan composter to process food waste from our Café into mulch for our Gardens.
  • Our Café has replaced single-use plastic products with plant-based and commercially compostable Vegware – including disposable coffee cups, takeaway boxes, sandwich wrappers and straws.
  • We have two drinking fountains on site – a Victorian fountain near the Bandstand and a new water refill point near the main entrance, one of more than 20 across London provided by #OneLess and the Mayor of London, as part of the London Drinking Fountain Fund. The Café also offers free tap water refills and we are looking at greener alternatives to bottled water.
  • Our Gift shop has introduced a charge for plastic bags while we look for better alternatives, with the proceeds supporting our Project Coral conservation research. The shop stocks a number of fair trade items, as well as working with UK artisans and makers to create unique products inspired by the Horniman's collections.
  • The Café serves fair trade tea and coffee, locally sourced meat, free-range eggs and fish from sustainable sources, as well as local beer and cakes.
  • The weekly Horniman Farmers' Market is a locally sourced, locally sold market. See the current stallholders here.
