At a September 5 meeting, the European Commission most member states’ Emissions Trading System plans to allocate carbon allowances through 2020. Proposals from the Czech Republic and Germany were not approved because they were found in noncompliance with allocation rules. The third phase of the system, which lasts from 2013 to 2020, will be conducted via auctions; the Commission reported that approximately 43 percent of the allowances in this phase will be free.
