New and Updated Data

 

Updates and Extensions of Electricity Market Data

 

In the attributional system models, market compositions are available for all 142 countries which are part of the IEA statistics: 100% of (statistically represented) global electricity generation is covered by country-specific market data.

 

The consequential system model contains new electricity market compositions for 40 countries, based on projections from the EU and the IEA. These new data eliminate important shortcomings of the consequential system model and provide a consistent basis for electricity supply in consequential LCA.

 

Indian Electricity by State and Grid

 

The electricity production in the ecoinvent database is not just updated on a regular basis, but new geographies are added and existing geographies are divided into smaller geographical regions to provide more detail.

 

India is the seventh biggest country in the world (by area), with a booming economy. As such, the role of India is becoming increasingly important when assessing the environmental impacts of the supply chains of many products. That is why more than 160 new electricity production datasets and markets for the 29 states and 5 electricity grids in India were introduced in ecoinvent v3.4.

Natural Gas

 

More than 100 datasets composing the European supply chains (all imports of natural gas to European countries) were updated. With this version, the database consistently reflects the most current technology and supply mixes in all the European countries and their major suppliers.

 

 

Chemical Products

 

With the update of more than 120 datasets and the introduction of 50 new products, ecoinvent significantly extended the coverage of the chemical sector. Version 3.4 includes more recent data for main exchanges, such as heat and electricity, as well as production volumes, CAS numbers, formulas, etc.

 

Recycling of PE and PET

 

New datasets covering the sorting and recycling of post-consumer polyethylene (PE) and polyethylene terephthalate (PET) packaging materials are now included in version 3.4. These new datasets broaden the range of waste fractions and recycling activities covered by the database.

Version 3 Commitments

Properties

 

All products and elementary exchanges in ecoinvent version 3 come with at least six properties, dry mass, wet mass, water in wet mass, water content, carbon content fossil and non fossil. Additionally every single product in the database has a price that can be used among other things for economic allocation.

 

Documentation

 

As in version 3.3, the newly released update of the ecoinvent database provides users with a comprehensive and easy to access documentation. The PDF documentation contains both unit process information as well as some key impact assessment results directly in the dataset. Find an example of pdf documenation here

System Models

 

ecoinvent is the only major LCI database supporting three system models: Allocation cut-off by classification, Allocation at the Point of Substitution, and Consequential. In addition, for all version 3 users preferring to have access to unlinked unit processes, ecoinvent offers an undefined version on its website.
