I = PAT
“How can we represent environmental impact based on resource consumption?”
Every society has an environmental impact. But since each society has different levels of resource consumption and utilization, each one is different. So how can we quantify this? Well, we can measure impact based on the average of the amount used multiplied by its energy efficiency and the total population. This is known as the I = PAT equation where I is the Environmental Impact P is the Total Population A is the Level of Affluence (how many resources are used) and T is the Technological Efficiency.
