ICI handles and processes many different materials. If released, each may have an impact on the environment. To create a measure of ICI’s overall environmental impact, we group emissions of individual substances into six categories of ‘environmental burden’:
- global warming,
- photochemical ozone creation,
- ozone depletion
- aquatic oxygen demand,
- hazardous air emissions, and
- acidity to air
For more details see ICI’s Environmental Burden booklet .
Burden factors
In 2005 we reviewed the burden factors used for individual substances in line with international standards, and have incorporated some changes for Greenhouse gases and Hazardous air emissions. For details see ‘ About our data’
