The Dutch Emissions Authority (Nederlandse Emissieautoriteit, NEa) is a competent authority which ensures that companies taking part in the European Emissions Trading System (EU ETS) and the laws and regulations governing renewable energy for transport and air pollution from fuels fulfil their obligations. The NEa does so by providing information and advice and by monitoring the companies involved (among other activities).

The NEa is an agency, with an Executive Board as a non-departmental public body (NDPB). In conjunction with the Ministry of Economic Affairs, the Ministry of Infrastructure and the Environment (IenM) is responsible for developing policy related to climate and renewable energy. The NEa ensures compliance with this policy within the bounds of its mandate.

The NEa performs its duties in the following areas:

• Emissions trading for stationary installations in the industrial and energy sectors (EU ETS)

• Emissions trading for aviation (EU ETS Aviation)

• Renewable energy and fuels (EV)

The NEa's duties include:

• Issuing and updating greenhouse gas emission permits;

• Allocating and issuing allowances;

• Managing the EV and EU ETS registries;

• Auctioneer of allowances;

• Monitoring compliance with laws and regulations.
