The Human Impacts Database

A collection of useful numbers for quantifying the impacts of the human presence on Earth.

This quantity is a single measurement of the quantity at a given point in time (2021).


Value:		≈ 9000 - 14000 kg CO₂e / t see this value in other units This is equivalent to... ≈ 9 - 14 kg CO₂e / kg
HuID:		31787
Relevant Year(s):		2021
Summary:		Carbon dioxide (CO₂) equivalent greenhouse gas emissions from wild bivalve production. Transportation and emissions from the fishing boats are a large portion of these.
Method:		This value comes from a compilation of life cycle analysis studies. They used hierarchical Bayesian modeling to estimate stressors at the species level and used global production values to obtain means for taxonomic groups. The upper and lower bounds reported represent 50% of the width of the distribution of the parameter obtained from Bayesian modeling.
