Carbon Footprint

Introduction

By carbon footprint (CF), we mean the emission of greenhouse gases, in terms of CO2 equivalent, attributable to a product, an activity, an organization or an individual, estimated through a life cycle analysis (LCA - life cycle analysis). In other words, in the CF estimate, the different materials or activities that originate the emissions are considered, and these refer to the product or activity unit.

The logic of the CF is derived from that of the "ecological footprint", a concept coined in the mid-1990s and defined as "the overall bio-productive area used by a given human population (individual, family, community, nation) to produce the resources it consumes and to assimilate the waste it produces ”. While the ecological footprint considers different types of environmental impacts and pressures (for example, the occupation of physical space linked to an agricultural activity or the disposal of waste) and quantifies them in terms of the bio-productive land used, the CF considers only one of its components, that deriving from greenhouse gas emissions.

This calculator has been developed to highlight the carbon footprint of foods and to improve the generic calculations of computers such as Carbon Footprint that do not allow for updates and improvements in the calculation.

If you want to use it offline with excel, here is the corresponding exce

Electric energy
(kg CO2eq/year), negative if the impact is positive (if emissions are avoided); Emission Factor (EF): 0.445 kg Co2eq./kwh per national mix with 36.6% renewable, Source
(kg CO2eq / year), emissions avoided available to others if renewable input is greater than the levy
Thermal energy
(kg CO2eq/year) Sources: methane, LPG, wood
Transport
gCO2 / km / passenger; (motorcycle data) and average passengers. - motorcycle with a cylinder capacity of less than 125cc: 70 gCO2 / km - motorcycle with a cylinder capacity between 125cc and 500cc: 85 gCO2 / km - motorcycle with a cylinder capacity over 500cc: 112 gCO2 / km
(kg CO2eq / year); Sources: Car: Emissions Guide , Moto , Train , Bus + tram + MM , Plane
Water and waste
(kg CO2eq / year) Sources: Waste
Feeding
Considering one year of feeding, each food has a different impact, in the Emission Factor (EF) the default value is the average of the values accumulated in the study. However, these values can be modified, a minimum and a maximum are indicated in the comment. For example, in the case of meat from nearby breeding, it may be sensible to indicate the minimum if the supply chain is known and has little impact. On the other hand, it cannot be null except in rare cases (fruit and vegetables from its permaculture vegetable garden) because there are always impacts and the 'small is beautiful' and the 0 km are not sufficient conditions, indeed as the study says they can also to be inefficient. Another important consideration is that the waste of food on the whole supply chain is very impactful (20-30%) so it must at least consider the weight of the total food taken.
(kg CO2eq / year) Sources: The carbon footprint of food

Carbon footprint values representative of 40 different types of food products (in brackets the number of IC values collected for each category is shown, on which the statistical indexes are calculated).
For beef meat the maximum value is out of scale and is equal to 83.5 kgCO 2 and / kg.

CF Italian average: 2737 kgCO2eq / year / person

CF replacing beef with poultry meat: 2372 kgCO2eq / year / person

CF Change from current to Mediterranean diet: 2226 kgCO2eq / year / person

CF Change from current to vegetarian diet: 2117 kgCO2eq / year / person
eliminating post-production food waste (retailers and consumers): 1788 kgCO2eq / year / person

 

Results
(kg CO2eq / year / person), total avoided emissions available to others
The average carbon footprint of the inhabitants in Italy is 5270 kg CO2eq / year / person

The average carbon footprint for industrialized nations is about 11000 kg CO2eq / year / person

The average global carbon footprint is 4000 kg CO2eq / year / person.

The worldwide goal to combat climate change with a 1.5 ° objective:

carbon budget: 420 GtCO2 (ref. SR15_SPM C.1.3), per person 52 tCO2, net zero around 2050.
IPCC Special Report: Global Warming of 1.5 ºC
