National Emission Reduction Commitments (NEC) Directive

NEC Directive¹ establishes a binding framework to reduce emissions of key air pollutants, thereby improving air quality and protecting human health and ecosystems. It sets domestic emission reduction commitments for five primary pollutants: nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), sulphur dioxide (SO₂), ammonia (NH₃), and fine particulate matter (PM2.5). The directive is a central pillar of EU air quality policy, addressing emissions at source across multiple sectors, including energy, transport, industry, agriculture, and residential heating.

The directive establishes two compliance periods. The first applies from 2020 to 2029, while a second, more stringent set of emission reduction commitments applies from 2030 onwards. The 2030 commitments are designed to significantly reduce the adverse health impacts of air pollution, with the overall objective of cutting related health damage by around half compared to 2005 levels. To deliver these commitments, authorities are required to prepare, adopt, and regularly update  Air Pollution Control Programmes (NAPCPs)² that set out the policies and measures needed to achieve emission reductions in a coherent, cost-effective manner.

Application of the EMEP/EEA Air Pollutant Emission Inventory Guidebook³ can support the preparation of consistent, transparent, and comparable emission inventories. The Copernicus Atmosphere Monitoring Service⁴ provides supplementary modelling tools and Earth observation data that can support emission verification, trend analysis, and the assessment of potential exceedances.

The Industrial Emissions Directive (IED)

The Industrial and Livestock Rearing Emissions Directive⁵ (Directive 2010/75/EU; IED 2.0 – Directive (EU) 2024/1785) is the central EU legal framework for preventing and controlling pollution from large industrial installations and intensive livestock rearing activities. Recently revised as IED 2.0 through Directive (EU) 2024/1785, it strengthens the EU’s approach to integrated pollution prevention and control and supports the objective of achieving zero pollution by 2050. The directive seeks to reduce emissions to air, water, and land while promoting resource efficiency, circular economy principles, and high levels of environmental and health protection.

At the core of the directive is the application of Best Available Techniques (BAT), which form the basis for environmental permitting. BAT represents the most effective, technically advanced, and economically viable methods for preventing or reducing emissions, as identified through the EU-level Sevilla Process⁶. These techniques and associated emission levels are documented in BAT Reference Documents (BREFs)⁷ and legally binding BAT Conclusions (BATCs), which guide permitting authorities in setting emission limit values and operational conditions. IED 2.0 further strengthens enforcement by tightening emission standards, streamlining permitting and reporting through a dedicated Industrial Emissions Portal, and enhancing public access to justice, including the right to seek compensation for health damage resulting from unlawful pollution.

The recast directive also expands its scope to cover additional activities with significant environmental impacts, including metal mining, large-scale battery manufacturing facilities, and major landfills. By broadening coverage and strengthening transparency and enforcement mechanisms, IED 2.0 reinforces the role of industrial emissions control as a cornerstone of the EU’s zero pollution and industrial transformation agenda.
