Abstract: A centralized emission management system is implemented via a server that is accessible to a large number of entities. The entities upload information relevant to determining a measure of environmental impact. The server calculates benchmarks for a performance metric based on the entities' measures of environmental impact and certain normalization factors. Based on a comparison of the performance metric of an entity against one or more benchmarks, the server may transmit initiatives to the entity for reducing environmental impact and an alert to related subordinate entities to reduce their environmental impact.

Abstract: A system and method for generating an updated version of, or reconstructing a previously enforced version of, a local client security policy stored in an application guard. A policy manager distributes a change (or an accumulation of changes) to the currently enforced version of the security policy through a network to the application guard. The application guard uses the distributed change to update the currently enforced version of the local client security policy. To reconstruct a previously enforced version of a local security policy, the policy manager generates a reversing delta equal to the reverse of the change (or accumulation of changes) from a previously enforced version to the currently enforced version of the security policy, and distributes the reversing delta through the network to the application guard. The application guard applies the distributed reversing delta to the currently enforced version to reconstruct the previously enforced version.
