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...

This paper describes the WITCH - World Induced Technical Change Hybrid - model in its structure, calibration, and the implementation of the SSP/RCP scenario implementation. The WITCH model is a regionally disaggregated hard-linked model based on a Ramsey type optimal growth model and a detailed...

Carbon taxes are advocated as efficient fiscal and environmental policies, but they have proven difficult to implement. One reason is that carbon taxes can aggravate poverty by increasing prices of basic goods and services such as food, heating, and commuting. Meanwhile, cash transfer programs...

Developing Asia has the world's fastest greenhouse gas emissions growth. This study uses an economy-energy-climate model to assess the effects of Paris Agreement pledges on Asia, in comparison with business as usual (BAU) and more ambitious scenarios. Results confirm that pledges must be...

To mitigate climate change, some governments opt for instruments focused on investment, like performance standards or feebates, instead of carbon prices. We compare these policies in a Ramsey model with clean and polluting capital, irreversible investment and a climate constraint. Alternative...

Carbon dioxide removal (CDR) is a potentially important climate strategy for attaining low climate stabilization objectives. However, climate analysis has indicated a possible weakening of the ocean carbon sinks -the largest in the world- in relation to CDR deployment. Here, we provide an...

Latin America and the Caribbean must respond to the challenge of climate change while making progress with other sustainable development goals. How much will it cost to meet climate change goals in this context? This work reviews the evidence on the costs of meeting the goals the goals of the...

Governments worldwide have agreed that international climate policy should aim to limit the increase of global mean temperature to less than 2oC with respect to pre-industrial levels. The purpose of this paper is to analyse the emission reductions and related energy system changes in various...
