This descriptions details the amount of carbon dioxide equivalent prevented as a result of the work of the BOCS Foundation, which is also a short summary of the QFPS™ standard, and the methodology of the generation of QFPC™ carbon credits.
The BOCS Foundation’s expenditures on public utility work was millions of forints every years. We regard 20% of this as indirect costs (e.g. accounting), so we only calculate with 80% of the spendings:
year 20xx: xxxx thousand HUF → its 80%: yyyy thousand HUF
It is expedient to take inflation into account, which results in earlier spendings to worth more in the present. This makes it possible to use the relations of a fresh report on the efficiency of spendings in the case of earlier expenses. This kind of value tracking may be calculated using valorization multipliers. Based on the 1st appendix of the 69/2017. (III. 31.) government decree, the above values are modified in the following way compared to 2016: zzzz thousand HUF
Since there is no Hungarian data available to estimate the cost efficieny of efforts aimed at preventing unintended pregnancies, we will use global data in the next step. According to the 2016 report of the Guttmacher Institute, the global average cost of preventing an unintended teenage pregnancy for a year is 128.33 USD, or 32 923 HUF. (2017.09.01. USD exchange rate: 256.55)
Using this exchange rate in our calculations, based on the spendings on public utility work of the BOCS Foundation in the last few years, the number of prevented unintended pregnancies is: z
Every year, 102 million of the 208.2 million pregnancies worldwide ends with the birth of the wanted child (49%), 41 million in abortion (20%), 31 million in miscarriage (15%), and 33.3 million in the birth of the unwanted child (16%). Globally, the ratio of intended pregnancies os 59%, and the ratio of unintended pregnancies is 41% (85.4 million).
What percentage of the unintended pregnancies ends in the birth of the unwanted child? We can get this ratio by dividing the number of unwanted children born (33.3 million) with the number of unintended pregnancies (85.4 million. Based on this, 39% of the unintended pregnancies end in the birth of the unwanted child. Therfore, 39% of the z number of the prevented unintended pregnancies attributed to the work of the BOCS Foundation would have resulted in the birth of the unwanted child, so the Foundation has prevented c number of unwanted births during this time.
Although the activity of BOCS has a global effect, it is mostly carried out in Hungary, so in the next step, we will use Hungarian data again. This simplification is decreasing the result, because the world average (4,97 t/capita) is higher than the Hungarian average. According to the World Bank, the Hungarian carbon footprint is 4.27 t/year (the most recent data is 2014). This is amount of greenhouse gases emitted by an average Hungarian in a year, expressed as carbon dioxide equivalent. According to the most recent data of WHO from 2015, the average life expectancy in Hungary is 75.5 years. Based on these sets of data, we can calculate how much greenhouse gas emission the BOCS Foundation has prevented in the past few years, using this formula:
Number of unborn unwanted children c (capita) x average Hungaian annual carbon footprint f (tonCO2e/year) x average life expectancy A (years) = G
G=c x f x A
Since carbon footprint changes from year to year, in order to make our calculations more accurate, we take the following into consideration: The calculated value is increased a bit by the fact that the actual per capita emissions in Hungary were somewhat higher between 2010 and 2013 than in 2014. On the other hand, the European Communities agreed in 2011 that they reduce their own greenhouse gas emissions in the following pattern: by 20% by 2020, by 40% by 2030, by 60% by 2040, and by 80% by 2050, related to the 1990 level. If these objectives are also met in the case of Hungary, then by 2050, per capita emissions will be reduced to about the third of the 2013 level. In Hungary, annual carbon footprint in 1990 was 6.71 tonnes, and it is 4.27 tonnes now, which is 63% of the former. Therefore, today’s level roughly equals the 2030 objective. The expected 2050 Hungarian annual carbon footprint is 1.34 tonnes, which is 31% of the 2014 level.
Between 2010 and 2014, we are calculating using available date, and between 2014 and 2050, we infer that the amount of annual per capita emissions will decrease linearly, from 4.27 tonnes to 1.34 tonnes, and then it will stabilize at that level.
Thus, the above G value changes to QFPC tonCO2e.
