GHG Scope 3: Start with Product-Specific Data from LCA\/EPD \u2014 or with General Data?<\/h2>\n\n\n\n
<\/div>\n\n\n\n

When organizations begin calculating their GHG Scope 3 emissions<\/strong>, a common question arises: do you need to start directly with product-specific data from LCA or EPD<\/strong>, or is it acceptable to begin at a more general level using generic data<\/strong>?<\/p>\n\n\n\n

<\/div>\n\n\n\n

The answer is that it depends on the requirements, drivers, and how mature the organization is in its sustainability work.<\/p>\n<\/div>\n<\/div>\n\n

Different Paths into GHG Scope 3<\/h2>\n\n\n\n
<\/div>\n\n\n\n

GHG Scope 3 covers emissions across the entire value chain. Because of its broad scope, specific data on environmental impact from multiple suppliers is often not available. This gap needs to be filled when calculating Scope 3, either with specific data from suppliers or with generic data. <\/p>\n\n\n\n

<\/div>\n\n\n\n

Some companies, such as Essem, have chosen to start with product-specific EPDs for their largest product groups. This provides good, specific results for the majority of their Scope 3 calculations. Other companies do not have access to product-specific LCA data at an early stage. In those cases, general data is often the most effective starting point. <\/p>\n<\/div>\n<\/div>\n\n

General Data Provides Guidance<\/h2>\n\n\n\n
<\/div>\n\n\n\n

When specific data from completed LCAs is not available, the impact can be calculated using generic data based on standard assumptions for the production of the purchased product or material. This is a fully accepted and often necessary starting point for a GHG Scope 3 calculation. <\/p>\n\n\n\n

The advantages of general data are that it:<\/p>\n\n\n\n
