On the motion of the Environmental Committee as the leading committee, the second reading of the Bill on Amendments to the Ambient Air Protection Act (422 SE), initiated by the same Committee, was concluded. The main objective of the Bill is to provide the principles of the allocation of the national reserve of permitted greenhouse gas emissions. The reserve provided by the allocation plan for permitted greenhouse gas emissions is divided into the reserve for new entrants to the trading system and the joint implementation projects reserve. The amendment proposed by the Bill concerns the principles of the allocation of the reserve for new entrants to the trading system. The permitted greenhouse gas emissions of the national reserve will be allocated between new entrants to the trading system at one time for the whole trading period by years according to the extent of the national reserve. According to the approval of the European Commission, the average total permitted emission is 11 832 452 tons of carbon dioxide for Estonia on the basis of the allocation plan for permitted greenhouse gas emissions for installations for 2008–2012. The European Commission’s Directorate General for Environment will not approve the national reserve for new entrants to the trading system before the principles of allocation of the national reserve will have been provided by legislation and this is the purpose of this Bill. The Bill was sent to the third reading.
