Leopold matrix

[1] It is used to identify and assign numerical weightings to potential environmental impacts of proposed projects on the environment.

[4][5] The matrix is also capable of expanding and contracting based on the scope and environmental context of any given undertaking, rendering it functional for both large and small-scale projects.

[2] Finally, it is beneficial to practitioners that the tool can be applied at various temporal stages of the environmental impact assessment process.

[7][8][9] In the same vein, the method has also been identified as lacking the ability to facilitate any degree of public involvement, primarily due to the subjective value judgements of the user.

[20][21][22] Due to the presentation of completed matrices, the method has also been identified as treating interactions as though they are certain to occur, with no consideration of probability.
