3. Proposed disaggregation, links to policymaking and its impact

Proposed disaggregation Link to policymaking Impact

Hazardous waste generated, by relevant sub-national territorial division (tonnes)(UNEP 2021e)

Applies to:

  • EN_HAZ_GENV

This disaggregation is useful for spotting and localizing the main sources of hazardous waste and for taking appropriate measures to reduce sources of hazardous waste pollution to minimize adverse effects on human health and the environment(UNEP 2021e). It can be used to support sound management of hazardous waste at the local level to minimize associated health and environmental risks(OPN n.d.).

This disaggregation is consistent with the Basel Convention - Article 4(UNEP 2019e).

Having improved information on the quantities of hazardous waste generated at local levels empowers policymakers with required evidence to lower such impact on the surrounding environment and communities, which can exacerbate as air, water, soil, and land pollution.

In addition, local policymakers and authorities have the prominent role ofenforcing waste legislation and implementing national waste strategies to prevent the impacts of inappropriate waste management, especially for poorer populations who are the most vulnerable(UNEP 2015; OECD 2023c).

Hazardous waste generated by economic sector (ISIC) (tonnes)(UN 2008a; UNEP 2021e):

  • Agriculture, forestry and fishing
  • Mining and quarrying
  • Manufacturing
  • Electricity, gas, steam and air conditioning supply
  • Construction
  • Other economic activities

Applies to:

  • EN_HAZ_GENV

This disaggregation provides a breakdown of the production of hazardous waste by economic activities in accordance with the ISIC Rev.4(UN 2008a). It is helpful in identifying the main sources of hazardous waste generation and adapting, as necessary and on the basis of enhanced evidence, the hazardous waste policy and required actions for reducing impact on the surrounding environment and communities.

This disaggregation is consistent with the Basel Convention - Article 4 and Annex 1(UNEP 2019e).

Assessing quantities of generated hazardous waste can lead to implementing policies that target the sound management of hazardous waste, which protect the surrounding environment and communities as a result(UNEP 2015; OECD 2023c).
