NETL CO2U is an open source database developed by the National Energy Technology Laboratory, U.S. Department of Energy focusing mainly on the USA's energy options.

The NETL CO2U openLCA LCI Database Version 2 is part of the NETL CO2U LCA Guidance Toolkit for Carbon Utilization funding recipients to meet their LCA requirements.

NETL uses life cycle analysis (LCA) as a tool and framework for evaluating energy technology and policy options on a common basis. LCA includes the environmental burdens of converting fuel to useful energy, infrastructure construction, extraction and transportation of fuel, and transport of the final energy product to the end user. NETL's LCA method also includes life cycle costing (LCC), which applies cost metrics to the same boundaries as their environmental models. NETL has applied LCA to fossil, nuclear, and renewable energy systems that produce electricity and liquid fuels. The final products of these LCAs include detailed reports as well as dynamic software tools.
