Guidance Documents

This page features guidance documents to help with conducting life cycle assessments. Most of the information on this site was sourced from the Global CO2 Initiative’s guidelines, and there are different approaches or emphases in other guidance.

However, both the Global CO2 Initiative’s guidelines along with those from the National Energy Technology Laboratory (NETL) are consistent with the ISO 14040 and 14044 life cycle assessment guidelines. This article expands on this subject.
