The experts from Greenhouse Marketeers will draw up an improvement plan based on the environmental impact. The most sustainable applications were already incorporated when World Horti Center was constructed, but we still think is important to obtain an insight. That is why Greenhouse Marketeers are calculating World Horti Center’s footprint, and we will offset this by planting bamboo through Bamboo Village Uganda on the basis of the results. That sounds very laudable, but what does it actually mean? We talked to Greenhouse Marketeers, who explained that it’s important to understand a couple of things.
Firstly, the term ‘footprint’. A footprint is a measure of how much impact something has on something else. The most commonly used footprint is the carbon footprint, which shows how much impact something has on global warming, expressed in CO2 equivalents. This means that there needs to be a calculation of how much greenhouse gas is emitted, after which this is converted to CO2. Methane, for example, is a more potent greenhouse gas than CO2: for every kilogram of methane emissions a figure of 25 kg of CO2 is calculated.
We are calculating the carbon footprint for World Horti Center: we are therefore calculating how much CO2 World Horti Center emits, i.e. how much impact World Horti Center has on global warming. We also need to define this first: what is the aim, the scope and the functional unit?
