The rules in the first two trading periods of the EU emissions trading system (EU ETS) differed in important respects from those of the current third period (2013-2020).
The 1997 Kyoto Protocol set for the first time legally-binding emissions reduction targets, or caps, for 37 industrialised countries. This led to the need for policy instruments to meet these targets.
In March 2000, the European Commission presented a green paper with some first ideas on the design of the EU ETS. It served as a basis for numerous stakeholder discussions that further helped shape the system.
The EU ETS Directive was adopted in 2003 and the system was launched in 2005.
The cap on allowances was set at national level through national allocation plans (NAPs).
This was a 3-year pilot of ‘learning by doing’ to prepare for phase 2, when the EU ETS would need to function effectively to help the EU meet its Kyoto targets.
Key features of phase 1:
Phase 1 succeeded in establishing
In the absence of reliable emissions data, phase 1 caps were set on the basis of estimates. As a result, the total amount of allowances issued exceeded emissions and, with supply significantly exceeding demand, in 2007 the price of allowances fell to zero (phase 1 allowances could not be banked for use in phase 2).
Phase 2 coincided with the first commitment period of the Kyoto Protocol, where the countries in the EU ETS had concrete emissions reduction targets to meet.
Key features of phase 2:
Because veriﬁed annual emissions data from the pilot phase was now available, the cap on allowances was reduced in phase 2, based on actual emissions. However, the 2008 economic crisis led to emissions reductions that were greater than expected. This led to a large surplus of allowances and credits, which weighed heavily on the carbon price throughout phase 2.
The market in emission allowances developed strongly from the start.
In phase 1, trading volumes rose from 321 million allowances in 2005 to 1.1 billion in 2006 and 2.1 billion in 2007, according to the World Bank’s annual Carbon Market Reports.
The EU ETS remained the main driver of the international carbon market during phase 2. In 2010, for example, EU allowances accounted for 84% of the value of the total global carbon market. Trading volumes jumped from 3.1 billion in 2008 to 6.3 billion in 2009. In 2012, 7.9 billion allowances were traded (worth €56 billion).
Daily trading volumes exceeded 70 million in mid-2011, data compiled by Bloomberg New Energy Finance and London Energy Brokers Association show.
