In the wake of life cycle assessments of a digital camera, comparing a normal type (144g) with a slim one (133g), the slim type had a 25% less impact on the environment, while the difference in weight is a mere 8%. This clearly indicated that improvements, such as eliminating the soldering Pb, reducing the surface size of the print circuit, simplifying the assembly process, or improving the packing material can have a greater affect than reducing the weight alone. .
