Best Available Techniques (BAT) to Prevent and Control Industrial Pollution


What's new

Read the OECD’s new report on Best Available Techniques (BAT): Measuring the Effectiveness of BAT Policies (2019). The report is also available in Russian

While a growing number of countries use BAT as a key policy tool to prevent and control the emission of industrial pollutants, many countries lack appropriate datasets to measure the effectiveness of their BAT-based polices. This report presents the first major cross-country analysis of ways to evaluate the impact of BAT-based industrial pollution policies, providing analyses of data from the European Union, the United States, Chile, Israel, Korea, the Russian Federation, India, the People’s Republic of China, Kazakhstan and New Zealand.

Why the OECD works on Best Available Techniques (BAT)


An increasing number of countries use BAT as a tool to establish evidence-based environmental permit conditions for industrial installations, in order to prevent and control industrial pollution, and thus to ensure a high level of human health and environmental protection. BAT are state-of-the-art techniques that are developed at a scale that enables implementation under economically and technically viable conditions.

Countries spend significant resources on designing, developing and implementing policies for BAT-based permitting. Therefore, there is an added value in sharing experience, knowledge and best practices on this topic amongst OECD member and partner countries. The OECD’s BAT project has so far resulted in the following publications:

The overall objectives of the OECD’s BAT project are to assist governments to implement policies and practices that embody BAT (or similar concepts) to prevent and control industrial pollution, and to contribute to progress towards achieving the Sustainable Development Goals (SDGs).

Forthcoming activities for 2019-2021

OECD member and partner countries have given their support for the BAT project to continue for another three years. For the period 2019-21, the project has the following three objectives:

  • Develop guidance on determining BAT, deriving BAT Associated Emission Levels (BAT-AELs) from BAT and translating BAT into Emission Limit Values in environmental permits for industry operators
  • Conduct a study on the challenges and opportunities associated with value chain approaches to establishing BAT for industrial installations
  • Compare BAT and BAT-AELs across countries for selected sectors and/or pollutants
