Earth Day 2025
22 April 2025
,Every year on the 22 April, Earth Day is celebrated across the globe. The aim of Earth Day is simple: “to diversify, educate and activate the environmental movement worldwide”. 2025 marks the 55th anniversary of Earth Day and the theme is “Our Power, Our Planet”.
Amgueddfa Cymru declared a climate emergency and a nature emergency in 2019. We have long taken our commitment to protecting the environment seriously, but since this important milestone, we’ve increased our efforts and provided inspiration for others to follow. Amgueddfa Cymru is uniquely placed to be a centre of learning and discovery for the Welsh public and for visitors from further afield. We are committed to preserving historic items, maintaining beautiful buildings, keeping traditional skills alive and reducing our negative impact on the environment – all so that future generations can enjoy and be inspired by the same things that we have been fortunate enough to experience.
This blog explores some areas where Amgueddfa Cymru has been active. Whether at home or work, how might you contribute to the Earth Day philosophy?
Biodiversity and Nature
Amgueddfa Cymru boasts a variety of outdoor spaces – from the dramatic landscapes surrounding the National Slate Museum in Llanberis, to the sweeping moorland of Big Pit in Blaenavon, to the tranquil marshy meadow of the National Wool Museum in Drefach Felindre. There is a wide variety of species living in these special habitats.
Amgueddfa Cymru is fortunate to have a team of dedicated Natural Sciences curators with specialisms in Botany and Zoology. As well as caring for the Museum’s sizeable collection (c. 5 million objects), the curators are actively involved in fieldwork and research. The curators carry out surveys at of our 8 sites and recommend actions to maintain and enhance the habitats, so as to maximise the chances of increasing biodiversity. Over time, it will be interesting to see how climate change impacts the species living at sites.
At National Museum Cardiff and St Fagans National Museum of History, the Gardening Team and Volunteer Team work to develop wildflower meadows by sowing yellow rattle and taking part in “No Mow May” (and June, July etc.). Such activities will encourage pollinators to the area. Why not visit in Spring or Summer and see how many species you can identify? Alternatively, visit the National Wool Museum and follow the family friendly Meadow Trail.

Sustainability, Reuse and Self-Sufficiency
Several of Amgueddfa Cymru’s sites showcase sustainable methods and ways of life from the past. The methods and materials used to construct the historic buildings re-erected at St Fagans can provide learning points for us today. The story of the ingenuity of Welsh minds is expressed at the National Waterfront Museum Swansea while the National Wool Museum and National Slate Museum demonstrate how key Welsh industries harnessed the power of water and displayed a remarkable level of self-sufficiency.
Moving away from a linear economy (take, make, waste) and towards a circular economy is key to preserving the planet’s resources for future generations. A recent example of the reuse culture within Amgueddfa Cymru is the refurbishment of the shop at Big Pit. Old coal drams were reclaimed, lovingly restored and now take pride of place as a display feature in the shop.

Decarbonising
Amgueddfa Cymru is on a mission to decarbonise its built estate. Work has been on-going to reduce the consumption of fossil fuels at sites by upgrading equipment to more efficient versions and by replacing heating systems with electrically powered alternatives (e.g. air source heat pumps). Over 5 years (2019/20 to 2023/24), the consumption of natural gas has reduced by 36%. The National Roman Legion Museum and the National Slate Museum are already heated and powered entirely by electricity from 100% renewable sources.
A significant project took place from January to March 2025 when eight buildings at four sites had fossil fuel heating systems (natural gas, LPG an oil) replaced with air source heat pumps. The work took place thanks to funding from the Welsh Government Energy Service and will further reduce our carbon emissions.
