The estimation of emissions will be based on a bottom-up approach, as this is considered to be the most reliable approach since it is based on a more detailed knowledge of the emitting sources (vehicle fleets related to logistics and waste collection) and implies the adjustment of the calculations to the specificity of the polluting sources.

União de Freguesias de Sintra e a União de Freguesias de Massamá e Monte Abraão are the first parishes to embrace the project that will apply solutions using technological features as a pillar of its construction, where an IUE will be generated for each property in the parish. This IUE in turn may have several functionalities, but initially the functionalities will be the reading of domestic meters, the use of the IUE for an environmental logistics/delivery system, and the IUE will be fundamental for the installation, maintenance and accounting of the bio-waste separated by the project participants.

Equation 1

This "integrated approach that contemplates intelligent logistics solutions, based on collaboration and sharing, in order to optimize the number of vehicles and resources needed in several operations" (1) with Living Laboratory in Massamá and Monte Abraão Parishes (Sintra Municipality) translates into concrete results, namely:

The emission factors to be used in the estimation will be those in the EMEP/EEA guide (EEA, 2019), by vehicle category.

Note : the vehicle categories to be considered are: light vehicles (passenger and goods), heavy vehicles (passenger and goods) and all motorcycles and mopeds. The fuels to be considered include gasoline, diesel, liquefied propane gas (LPG) and natural gas.

Equation 2

Still regarding the estimation of emissions, if it is considered to estimate other pollutants, to determine the SO2 pollutant, the emissions are obtained through the variables indicated in Equation 3, where:

For pure electric (or battery electric) vehicles, the exhaust emissions will be zero, so they do not directly contribute to air pollutant emissions. All CO2 emissions that they produce implicitly will be due to the production of electricity, which is part of the power generation.

According to the factors published in Order No. 17313/2008, of June 26, for the purposes of accounting for carbon intensity by greenhouse gas emissions, it should be considered, in calculating CO2 emissions associated with electricity consumption, that the emission factor associated with electricity consumption is equal to 0.47 kgCO2e/kWh.

Equation 3

The processing of the data obtained should result in the average physical composition of the stream characterized, expressed in terms of the average values obtained for the percentage by weight of each category and subcategory, on a wet weight basis.
The following statistical parameters must also be determined at each category level:
