This website gives information about the regulatory approaches adopted by OECD member countries to mitigate pesticide risks to insect pollinators. Following a survey of OECD member countries, it was concluded that mitigation of risks to insect pollinators is important to all its member countries, and that mitigation is a critical component of balancing the benefits of plant protection products with potential risks to insect pollinators.

The first version of the Globally Harmonised Submission and Transport Standard was published May 2014.

PRTR have been established throughout the world to track releases and transfers of potentially harmful chemicals. But most of the PRTR systems were designed without considering comparability, each PRTR has its own requirement of reporting chemicals and sectors. To harmonise globally, OECD reviewed the reporting chemicals and sectors across PRTR systems and produced proposal for harmonised lists of reporting pollutants.

This guidance is intended to harmonise the way non-guideline in vitro test methods are described. This should in future facilitate an assessment of the relevance of test methods for biological activities and responses of interest, of the quality of data produced, irrespective of whether these tests are based on manual protocols or assay protocols adapted for use on automated platforms or high-throughput screening systems (HTS).
