# What is Factor X?

Factor X is a measurement that simultaneously considers both improvement to our quality of life through products that are easy to use, safe, and convenient, and production that is kind to the global environment.

## Relationship Between Factor X and Our Lifestyle

Factor X is an index that compares the environmental efficiency of a new product (the product being evaluated) with that of a previous product (reference product) and expresses the improvement in terms of a multiple (factor).
Environmental efficiency is a number derived by dividing "quality of life" by "environmental impact" that expresses the "value of the product in terms of its effect on the environment", where "value" means the life span and functions of the product.

### Improvement in quality of life means

• Making products easier to use
• Providing brighter and clearer images
• Extending product life spans, and so on

### Reducing the impact on the environment means

• Reducing emissions of greenhouse gases
• Reducing consumption of resources, and so on

The term "factor X" is used to represent the multiple of improvement over the current situation in terms of these measures. For example, "factor 4" means a four-fold improvement and "factor 10" a ten-fold improvement.
The higher the factor X value, the more the product helps achieve the "new affluence".

## Factor Evaluates Two Different "Environmental Impacts"

The two different factors used to evaluate "environmental impacts" are the factor of global warming prevention and the resource factor.

### Factor of global warming prevention

Numeric estimate of the contribution to global warming prevention (energy conservation)

First, obtain the efficiency of global warming prevention for the new product (product to be evaluated).

Next, compare against old product (reference product).

How to calculate the factor of global warming prevention
This calculates the factor of global warming prevention using a refrigerator as an example.

### Resource factor

Numeric estimate of the contribution to effective resource use

First, determine the resource efficiency of the new product (product to be evaluated).

Next, compare against old product (reference product).

How to calculate the resource factor
This calculates the resource factor using a refrigerator as an example.
