As part of actions to mitigate climate change, book and paper conservators increasingly implement sustainability-focused changes to their practice on either a personal or organisational level. Methods for increasing the sustainability of book and paper conservation work include the responsible sourcing of tools and repair materials (e.g. bamboo spatulas),[63] the use of less industrial chemical solvents and safer chemical alternatives, the use of fewer animal-sourced products (e.g. replacing gelatine glues with synthetic ethylene-vinyl acetate emulsions),[64] and reducing the amount of labour and energy required in conservation activities (e.g. preventive treatment measures, using materials sparingly).
