Countries have pledged to stabilize global warming at a 1.5 to 2°C increase. Either target requires reaching net zero emissions before the end of the century, which implies a major transformation of the economic system. This paper reviews the literature on how policymakers can design climate...

Over the coming decade, the power sector is expected to invest ~7.2 trillion USD in power plants and grids globally, much of it into CO2-emitting coal and gas plants. These assets typically have a long lifetime and commit large amounts of (future) CO2 emissions. Here, we analyze the historic...

Long-term Strategies for Decarbonization, termed long-term low emissions and development strategies (LT-LEDS) by the UNFCCC, and sometimes referred to as LTS, can influence the transition to a resilient and decarbonized economy. LT-LEDS additionally make it possible to identify investments and...

This paper investigates the optimal timing of greenhouse gas abatement efforts in a multi-sectoral model with economic inertia, each sector having a limited abatement potential. It defines economic inertia as the conjunction of technical inertia - a social planner chooses investment on...

Decision makers facing abatement targets need to decide which abatement measures to implement, and in which order. This paper investigates the ability of marginal abatement cost (MAC) curves to inform this decision, reanalysing a MAC curve developed by the World Bank on Brazil. Misinterpreting...

This paper finds that it is optimal to start a long-term emission-reduction strategy with significant short-term abatement investment, even if the optimal carbon price starts low and grows progressively over time. Moreover, optimal marginal abatement investment costs differ across sectors of the...
