Dear Frederico
Thank you for your question. Due to the holidays we won’t be able to provide you with an answer before the new year. We will get back to you as soon as possible.
Best Regards

Dear Frederico
Happy New Year!

First of all, I would like to refer you to the Portuguese greenhouse gas country profile which might be useful to you:

http://www.eea.europa.eu/[…]/greenhouse-gas-country-profiles

As for your questions:

1. It is fine to subtract ETS emissions from total emissions to obtain non-ETS emissions. This is for example a correct approach for assessing progress under the Kyoto Protocol, as explained in the latest EEA report on GHG trends and projections (http://www.eea.europa.eu/[…]/ghg-trends-and-projections-2011). As of 1st of January 2012, emissions from civil domestic aviation (IPCC category 1.3.1.a) must also be deducted from total emissions, since aviation is now covered by the EU ETS. More accurate calculations involve accounting for installations opted in and out of the EU ETS during the first phase 2005–2007 and/or the second phase 2008–2012 of the EU ETS. Here, it depends on the purpose of the calculation. But the simple subtraction is a fair approach. See also details provided in the abovementioned report.

2. The % target under the Kyoto Protocol must be applied against a base-year level that is now fixed and that does not exactly correspond to the latest 1990 emission data. In particular, the base year represents 1990 for emissions of CO2, CH4 and N2O, while 1995 is the base year for fluorinated gases. The base year therefore represents a kind of 'hybrid' year. Obviously, given the weight of CO2 in total emissions, the base year is much closer from 1990 emissions than from 1995 emissions. In addition, as allowed under the Kyoto Protocol, the base-year of Portugal includes GHG emissions from deforestation (all emissions by sources minus removals by sinks reported in relation to the conversion of forests) for 1990, which constituted a net source of GHG emissions in that year. The detailed calculations and final numbers are provided in the UNFCCC review report of Portugal's initial report under the Kyoto Protocol: http://unfccc.int/resource/docs/2007/irr/prt.pdf. In the EEA GHG viewer, there is a separate category for 'base-year' next to 1990. In short: Portugal's base-year emissions = 60.14764 Mt CO2 equivalent => target = 76.38751 Mt CO2 equivalent

3. Official absolute 2020 targets under the effort sharing decision (non-ETS emissions) have not been determined yet and will not be available before the end of this year. Any number is therefore currently provisional. Relative targets have been agreed, but the exact numbers for the calculation of the 2005 base-year are not available yet. You can still find such tentative calculation in the abovementioned EEA report on GHG trends and projections in Europe.

I hope this helps. Please do not hesitate to ask if you have further questions.

Hello,

First of all, sorry for my (very) late reply.
Thank you very much for your clarification on all items.

Kind regards,
