Background<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The choices we make regarding our food consumption and how they are produced have significant implications for both our health and the environment<\/a>. From growing and processing to transportation, distribution, preparation, consumption, and disposal, each stage of the food\u2019s lifecycle generates greenhouse gases<\/a>, contributing to climate change. Our carbon footprint<\/a>, this is, the amount of greenhouse gases<\/a> like carbon dioxide<\/a> and methane<\/a> that are generated by our actions, is heavily influenced by our food-related activities, with approximately one-third of human-caused greenhouse emissions linked to food production.<\/p>

The climate impact (this is, the carbon footprint<\/a>) of food can be quantified in terms of its greenhouse gas<\/a> emissions intensity, measured in kilograms of carbon dioxide<\/a> equivalents (kg CO2<\/sub> e) per kilogram of food (kg of food). Animal-based foods are generally associated with the highest greenhouse gas<\/a> emissions \u2013 but do all animal-based food alternatives contribute to the same extent? What are other factors in the food production chain that contribute to greenhouse gas<\/a> emissions?<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

In this activity, you will calculate the carbon footprint<\/a> of various animal-based food alternatives consumed in Nuuk, Greenland. The alternatives include poultry<\/a> and pork transported from Denmark by boat or plane, and locally hunted seal (hunted either near or far from the city). You will assess greenhouse gas<\/a> emissions from different phases of production and transportation, from the farm or field to the consumer<\/a>.<\/p>

<\/u>\"\" Handout 1<\/a><\/u> contains all the necessary tables to complete the activity and \"\" Handout 2<\/u><\/a>\u00a0includes a graph for plotting the final results.<\/p>

Start the activity by calculating the emissions from transporting pork and poultry from Denmark to Greenland by both boat and plane, using the data in Tables 1, 2 and 3 (<\/u>\"\" Handout 1)<\/a><\/u>. The provided data in Table 4 includes greenhouse gas<\/a> emissions from pork and poultry production (farming and the cultivation of food for feeding these animals), and emissions from hunting seals including fuel for the trip and ammunition (data from Ziegler et al., 2021; <\/u>\"\" Handout 1<\/a><\/u>), that you will use to calculate the total greenhouse gas<\/a> emissions from the production and transport of animal-based food alternatives in Greenland. Finally, compare these emissions by plotting the data on a graph (\"\" Handout 2<\/u><\/a>).<\/p>

  1. Start by calculating the greenhouse gas emissions from transporting 1 kg of poultry or pork from a farm in Aalborg (Denmark) to the port in Nuuk (Greenland). Use the information in Data Table 1 to complete Table 2 (<\/u>\"\" Handout 1<\/a><\/u>). Pay attention to the units!<\/li>
  2. Fill the \u201cTotal emissions from transport from Aalborg to Nuuk by boat\u201d in Table 2.<\/li>
  3. Repeat steps 1 and 2, but this time use the Table 3 to calculate the transport of poultry and pork by plane.<\/li>
  4. Copy your results into Table 4 and plot them on a stacked bar chart (\"\" Handout 2<\/u><\/a>) for each food alternative. Use different colors to represent each component (production, shipping, fuel, etc.) of the total greenhouse gas<\/a> emissions.<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
