 # Carbon Aware SDK
-The Carbon Aware SDK is a toolset to help you measure the carbon emissions of your software, 
-in turn helping you **measure and reduce your software's carbon emissions**.
+Carbon aware software does more when it can leverage greener energy sources, and less when the energy CO2 emissions are higher.

+The Carbon Aware SDK is a toolset to help you measure the carbon emissions of your software, in turn helping you **measure and reduce your software's carbon emissions**, and choose when and where you run your software to make it greener.

 By knowing the carbon emissions of the energy that powers your applications, 
-you and your organisation can make decisions on when and where to run your software, 
-and leverage greener energy sources.  
+you and your organisation can leverage greener energy sources to reduce your CO2 emissions by:  
 
-* Build your AI models when carbon emissions are lower
-* Deploy software into the cloud in locations that have greener energy sources
-* Run software updates at greener energy time windows 
-* Use data to run hypothetical models to understand how you could start driving impact and reduce emissions
