eiolca.net - Free Life Cycle Assessment on the Internet

	Introduction:
This 'Hybrid' feature allows you to perform a hybrid life cycle assessment (LCA) for a custom product. The term 'hybrid' indicates that you will be able to create your own theoretical sector through which you will be able to model a custom product or process based on input-output data from the EIO-LCA model and process LCA data to which you may have access. This feature will allow you to look beyond the aggregation of existing EIO-LCA sectors and towards a more fine-tuned analysis of various custom products, including early development, hypothetical, or existing products that may not be adequately modeled with the existing aggregation of the input-output sector in question (i.e. an electric car, palm pilot, hydrogen fuel cell, or specific existing product). This Hybrid feature will provide you with information regarding the sectors that directly contribute in the economic supply chain of a 'model' sector of your choice. Curious how the Hybrid feature operates? (Show / Hide) The economic numbers you're allowed to alter on the next page include the model sector's initial demand (I) and the direct suppliers for this demand (A) [hence, I+A]. To calculate the results of whatever changes you make, the Hybrid feature takes advantage of the large matrices already stored on the EIO-LCA server to support 'normal" EIO-LCA operation. Consequently, the Hybrid feature determines the change from the original model sector supply chain value for each sector (the difference between the original and revised value for each row). It then calculates a revised final demand as (I+A)model sector + delta(I+A). Any changes in I+A are consequently run through the entire EIO-LCA model so as to incorporate supply chain additions and circularities and present a truly hybridized sector that adequately portrays the economic and environmental results of a given purchase.
	Choose a model:
Your current model is the USEEIO 2012 Producer Model (v2.0.1-411), which is a Producer model. (What does this mean?)

Please select the input-output sector that you think best approximates your custom product by browsing through the model of your choice. Please enter the amount of economic activity you want in this sector: (What does this mean?) Million Dollars Sector descriptions will appear here.
