Emissions from the maritime industry will be included in two steps: carbon dioxide will be included in the ETS from 2024 whereas methane and nitrous oxide will be included from 2026. According to the European Commission, EU ETS covers the following sectors and gases, focusing on emissions that can be measured, reported and verified with a high level of accuracy: - carbon dioxide (CO2) from electricity and heat generation, energy-intensive industry sectors, including oil refineries, steel works, and production of iron, aluminium, metals, cement, lime, glass, ceramics, pulp, paper, cardboard, acids and bulk organic chemicals, aviation within the European Economic Area and departing flights to Switzerland and the United Kingdom; maritime transport
- nitrous oxide (N2O) from production of nitric, adipic and glyoxylic acids and glyoxal;
- perfluorocarbons (PFCs) from the production of aluminium.
