In the first activity cycle, CiViA will work on one of the environmental impact categories in the life cycle assessment (LCA): climate change. In this category, the environmental impact is caused by greenhouse gas (GHG) emissions throughout the product (good or service) life cycle stages. The calculation of GHG emissions associated with products is called carbon footprint.
There are a number of methods to calculate product carbon footprint; the three most popular ones are listed below. CiViA's goal is to qualify their members to be able to calculate their product GHG emissions, being aware of the concepts involved in such methods:
The first version of this method was published in 2008, and it is considered the first one to specifically cover calculation of GHG emissions associated with products.
It is known as PAS 2050.
This method was launched in 2011, within GHG Protocol initiative, well known for the method to account for corporate GHG emissions.
As it has not been translated into Brazilian Portuguese yet, it is usually called GHG Protocol for Products.
Greenhouse gases – Carbon footprint of products –
Requirements and guidelines for quantification
and communication (ISO).
In 2013, ISO published that specific norm to quantify and communicate product carbon footprint. Different from both norms listed previously, you have to pay for this one.
It is known as ISO 14067.
