The Spanish State, through Law 9/2020 of 16 December, amends Law 1/2005 to fully transpose EU Directive 2018/410 and align Spain's greenhouse gas emission allowance trading scheme with the 2021-2030 Phase IV framework. The legislation mandates a linear reduction factor increase to 2.2%, establishes auctioning as the primary allocation method, and introduces strict activity-level monitoring and mandatory return of excess free allowances for fixed installations. It further eliminates five-year authorisation reviews, updates free allocation percentages to phase out by 2030 for non-leakage-risk sectors, and strengthens coordination mechanisms between national and regional authorities alongside social dialogue participation.
