Implementation of the GAINS-model for a greenhouse gas and air quality strategy for South Africa

Carmen Klausbruckner of the Cape Peninsula University of Technology, South Africa, examined how well climate change and air pollution policies are integrated in South Africa.

Introduction

South Africa produces the most greenhouse gases (GHG) in Africa and is also a significant emitter on a global scale. In 2009, the country committed itself to reducing its GHG emissions compared to a business as usual trajectory. Another pressing issue in South Africa is air pollution: indoor air pollution is estimated to cause around 3,000 premature deaths per year, and fires create significant air pollution across the country, affecting 200,000 South Africans.

Methods

Based on a qualitative text analysis of legal and policy documents, and a comprehensive literature review, contradictions among different policy approaches were identified. Criteria for a decision support tool were established and tested for the extent to which the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model is consistent with these criteria.

Results

South African climate change mitigation and air quality policies are not always coherent, and in fact can be partially contradictory. Climate change policies can also conflict with the country’s development priorities, poverty alleviation, and employment policy, mainly as a result of increased electricity prices. However, there is the potential for co-benefits between air pollution and climate change mitigation policies. For example, the control of GHG emissions usually also leads to a reduction in local or regional air pollutants.

Conclusion

An integration of GHG and air pollution policies is required. A common evidence-based, transparent decision support tool that takes into account economic and social factors is needed for the development of policy decisions. The GAINS model provides an evidence-based approach to investigating policy alternatives. It links GHG emissions and air pollution and can optimize cost, GHG emissions, or health impacts (measured in disability-adjusted life years). Implementation of the GAINS model would therefore assist South Africa in the development of GHG and air quality policies, and would be in line with the country’s overall development goals.
