Some promises already made at St Barbe

(through carbon literacy training and during the HERDS project)

  • I am going to drive an initiative to introduce coffee bean composting into our cafĂ©
  • I'm going to buy second-hand books and toys (age 8)
  • I'm going to litter pick
  • Do the laundry only once a week (age 9)
  • I intend to research the best place to invest our Endowment Fund in a sustainably run and invested investment fund.
  • Installation of solar panels at the museum store at Braxton, to help power the air source heat pump (which is already installed).
  • I will actively seek to only use suppliers for our shop that put sustainability at the heart of their business. For example those that have FSC (Forestry Stewardship Council) certification and those that use either no plastic wrapping and that use sustainable plastic alternatives e.g. compostable packaging.
  • To reduce our contribution to the emissions generated through the manufacture and disposal of exhibition materials

St Barbe and sustainability

As part of its mission, St Barbe Museum has committed to:
"inspire greater respect for the planet and take a lead in developing more sustainable practices"

All staff and many volunteers have already received carbon literacy training and the Museum holds the Carbon Literate Organisation Bronze Award. It is working towards Silver.

Why Show Your Stripes?

Our planet is warming up. These climate stripes show how things are changing:

To raise awareness, people all over the world take part in #ShowYourStripes day around the summer solstice:

Why the Butterfly Effect?

Small changes can have a bit impact - but this project aims to gather in lots of tiny promises which together will help make a change.

The butterflies have already collected lots of promises!

knitted buterflies on Whitchurch Bridge

In May 2023, Art in the Community covered Whitchurch on Thames bridge with thousands of butterflies made from upcycled materials - knitted and crocheted using odd bits of yarn with some made by schoolchildren from shiny crisp packets to reflect the light.
