By constructing a dynamic general equilibrium model this paper studies the optimal pollution emission and abatement policies for a small economy. We show that in autarky government issues an optimal level of emission permits but its optimal abatement level is zero at the unique steadystate equilibrium. On the other hand, government employs an optimal two-dimensional policy with free trade if th...

The negatively charged nitrogen-vacancy (N-V(-)) color center in diamond is an important solid-state single photon source for applications to quantum communication and distributed quantum computation. Its full usefulness relies on sufficient radiative emission of the optical photons which requires realizable control to enhance emission into the zero-phonon line (ZPL) but until now is still a ch...

Abstract In recent years, global studies have attempted to understand the contribution that energy demand reduction could make climate mitigation efforts. Here we develop a bottom-up, whole-system framework comprehensively estimates potential for at country level. Replicable other countries, our is applied case of United Kingdom where find reductions in 52% by 2050 compared with 2020 levels are...

Emission reduction ambition in shipping and efforts to provide measures achieve zero emission the industry is increasing parallel global environmental concerns. Designing container schedules that create minimum emissions can help zero-emission target. This study proposed a comprehensive green scheduling model considering port sea passage disruption recovery i.e., speed adjustment, skipping, col...

Fuel economy regulation is a powerful instrument to reduce CO2 emissions of vehicles and has recently been extended heavy-duty vehicles. In Europe, truck manufacturers are required the newly sold by 30% until 2030 compared 2019/2020. Accordingly, several have announced introduction zero emission (ZEVs) such as battery electric or fuel cell trucks. However, sales shares trucks meet targets not a...
