Wallpapers can be sources of VOCs.

Choose wallpapers made from water-based paints to minimise harmful solvents. They should be bound using natural resins, and made from paper from an FSC certified sustainable source.

Currently it is very difficult (and expensive) to find environmentally friendly wallpaper, so you could as an alternative consider buying wallcoverings made from hemp, arrowroot, bamboo or wildgrass, which are readily available. They tend to be more expensive, but longer lasting.

Think also about buying water-based, chemical free wallpaper paste, such as Volvox, sold by Earthborn For wallpaper removal, try to avoid chemical based products, and use a steam stripper. Yes, it uses energy, but its better than releasing more enzymes into the atmosphere.
