Climate Co-benefits

The achievement of net-zero greenhouse gas (GHG) emissions by 2100 is required to limit global temperature rise below 2 °C above preindustrial levels. Earlier accomplishments of net-zero GHG emissions at the regional level support this global target. We investigate scenarios to achieve net-zero GHG emissions sustainably by using detailed modelling of energy system transformation, cross-sectoral connectivity, and technology penetration. In the meantime, the decarbonization research also quantifies the associated health co-benefits from reduced co-emitted air pollutants. Decarbonization policies, such as vehicle electrification and clean energy transition are expected to produce health co-benefits by reducing air pollutants emission while reducing GHG emission. We aim to evaluate the public health co-benefits from decarbonization policies, provide quantifiable and science-based knowledge which can better inform the public and decision-makers to formulate a fair-for-all climate mitigation policy.
