2. Developing the use of tools and methods

There are two types of tools and methods:

• environmental assessment tools;

• environmental improvement tools.

There are two main types of environmental assessment tools: multi-criteria approaches, covering several categories of environmental impacts (water, toxicity, biodiversity, human health), and single-criteria analyses focused, for example, on climate change and greenhouse gas emissions (e.g., Bilan Carbone®), water, or biodiversity (e.g., Global Biodiversity Score®).

The most comprehensive environmental assessment method is life cycle assessment (LCA)
