Abstract

How can economies achieve economic growth without causing negative environmental externalities? There are two aspects to the long-standing debate on 'sustainable growth'. A first-best solution is for economies to replace fossil fuels with renewable energy sources, mitigating carbon emissions. A second-best solution is for economies to also adopt efficient waste management, recycling residual waste and pollutants (including hard-to-abate carbon) from production (circular economy). We establish a simple growth model that integrates three fundamental pillars of economics: (i) the net-zero carbon target in environmental economics (ii) the circular economy, dealing with waste management in resource economics, and (iii) sustainable growth, in growth economics. We argue that growth, circularity and net zero emissions present a trinity of solutions to the sustainable growth problem, showing that the circular economy is a necessary condition for achieving net zero. We show that an economy with 'active' environmental policy achieves net-zero faster than one with 'passive' policy, and also eliminates carbon.
