Abstract

In 2021, Zimbabwe updated its Greenhouse Gas (GHG) reduction target from a 33% reduction in per capita energy sector GHG emissions to a 40% reduction from all sectors, compared to 2030 baseline emission scenarios. This work aims to demonstrate how the actions identified in Zimbabwe's Nationally Determined Contribution (NDC) can achieve this updated target, and what development benefits could be achieved in Zimbabwe through the implementation of these actions. The magnitude of GHG emissions in Zimbabwe are modelled historically, and to 2030 to quantify GHG emission reduction potentials, and contributions to selected sustainable development goal targets from implementation of 28 mitigation measures. The estimated ∼37 million tonnes CO2-equivalent emissions emitted by Zimbabwe in 2017 are projected to increase by 109% to ∼77 million tonnes without implementation of any mitigation measures. The mitigation measures included in the updated NDC could reduce GHG emissions by 40% in 2030 compared to the baseline, while additional measures included in other plans and strategies in Zimbabwe could achieve a further 23% reduction. Implementing Zimbabwe's NDC could also lead to substantial development benefits locally in Zimbabwe, including to public health, biodiversity, and sustainable energy use. This assessment therefore provides a clear pathway to achieve Zimbabwe's updated climate change mitigation commitment, as the target is linked to the implementation of specific, concrete mitigation actions. It provides a practical example as to how methods to assess climate mitigation and development priorities can be integrated within climate change mitigation target-setting assessments. The more widespread adoption of prospective, quantitative assessment of development benefits from climate change mitigation actions could provide further motivation for more ambitious climate change action.
