The signage and T-shirts have long been green. Now Mitzvah Day is encouraging a “greener” approach to local projects.

Its theme for November’s day of faith-based social action was launched on Sunday at the Jewish Vegetarian Society’s vegan centre in Golders Green.

The Mitzvah Day team shared ideas for “collecting, cleaning or making your project green” with activity co-ordinators and volunteers and unveiled the charity’s new artwork and T-shirts.

Reflecting the greener theme, guests upcycled old Mitzvah Day T-shirts into dog toys for nearby rescue centres.

“There is a clear Jewish imperative to care for our environment and this couldn’t be more important today,” said Mitzvah Day chief executive Georgina Bye.

“Even small things like picking up litter or recycling and upcycling old clothes and furniture can have a huge impact in helping others and helping our planet.”

Mitzvah Day chair Laura Marks added that “environmental issues are something which affect all of us, regardless of religion, creed or background. It’s a powerful current issue and an ideal theme for Mitzvah Day.”

Sunday’s event also featured discussion groups on the importance of interfaith work and on managing and supporting Mitzvah Day volunteers. An additional session on Jewish concern for the environment was led by Rabbi Mark Goldsmith of Edgware and Hendon Reform Synagogue.

A Manchester launch event for northern co-ordinators and volunteers will be held at the end of the month.
