Itsubo Lab
Machine-translated · View original
A lab that uses LCA to measure and evaluate the environmental impact of products across their entire life cycle.

AboutAbout the lab
Every human activity carries an environmental burden.
The Itsubo Lab studies LCA (life cycle assessment), which measures the environmental burden of products and services from the time they are made until they are disposed of.
LCA is internationally recognized as a method for corporate environmental management, and its procedures are defined by ISO (International Organization for Standardization) standards.
In recent years, the lab has also been developing new indicators to assess the impact of land-use change on biodiversity and nature-related risks.
Key terms
- LCA (Life Cycle Assessment)
- An assessment method that measures, as a whole, the environmental impact of a product or service from the time it is made until it is disposed of.
- Biodiversity
- The variety of living things on Earth and the connections among them.
- Nature Footprint
- A new assessment measure that expresses the size of the impact that corporate activities and the like have on the natural environment.

*Illustrative imageEnvironmental Impact Assessment Using LCA
The lab conducts research that evaluates environmental impact using LCA, a method for quantitatively measuring the environmental burden that a product or service causes from its creation to its disposal.
*Illustrative imageAssessing Impacts on Biodiversity
The lab is developing methods to quantitatively assess the impact of land-use change on biodiversity around the world, at a high resolution that reflects regional differences.
*Illustrative imageAssessing the Health Impacts of Climate Change and Air Pollution
The lab studies methods to quantify the effects of CO2 emissions and air pollutants such as PM2.5 and ozone on human health, taking future societal scenarios into account.
*Illustrative imageDeveloping the Nature Footprint
The lab is developing and field-testing an assessment indicator called the "Nature Footprint," so that companies and financial institutions can understand their impacts and risks related to nature.
