It is often used when it comes to environment. For example, if we are speaking about a Corporate Carbon Footprint or Product Carbon Footprint, ‘hotspot’ is where there is the greatest concentration of greenhouse gas emissions: hotspot can be one of the 3 Scopes (Scope 1, 2 and 3), a subcategory of Scope 3, a phase in the product’s life cycle, a particular production process, and so on. 

​

Or if we are speaking about biodiversity, hotspot can mean a region which is particularly rich in biodiversity that is threatened by habitat loss, climate change and other pressures which may be attributed to human activities.​​
