The Greenhouse Energy Guide Simulator is an online tool for calculating the effects of different (combinations of) renewable energy sources on the environmental foodprint, expressed in energy consumption, crop performance, variable costs and CO2-emission according to the European Union Emissions Trading System (EU ETS). This means that the CO2-emission from fuel combustion is counted as contribution to emissions (each fuel has its own conversion factor per unit of fuel). Emissions related to import of commodities to a greenhouse (e.g. electricity, heat, fertilizer) are not attributed to the greenhouse enterprise. The other way around, savings on CO2 emission by third parties because of services from a greenhouse (heat, electricity or CO2 supply) are not subtracted from the greenhouse CO2 emission.
