Traditionally, voluntary measures have been evaluated using the same framework regardless of their structure. The framework assumes that the measure provides partners with a treatment (information, research support, etc) that will not be transferred to nonpartners. In this framework, a voluntary...

The framework for voluntary program evaluation assumes that voluntary programs provide partners with information that will not be transferred to non-partners. In this framework, a voluntary program is said to be worthwhile if there are significant differences between the behavior of partners and...

Mineral carbonation of alkaline waste materials is being studied extensively for its potential as a way of reducing the increased level of CO2 in the atmosphere. Carbonation converts CO2 into minerals which are stable over geological time scales. This process occurs naturally but slowly, and...

One of the options that can contribute to the reduction of carbon dioxide emissions for climate change mitigation is the so-called CO2 sequestration by mineral carbonation, or CO2 mineral sequestration. Steel manufacturing could benefit from this option by utilizing its own by-products, i.e....
