Carbon dioxide removal from the atmosphere is becoming an important option to achieve net zero climate targets. This paper develops a welfare and public economics perspective on optimal policies for carbon removal and storage in non-permanent sinks like forests, soil, oceans, wood products or...

We study optimal climate policy in a global economy where regions differ in wealth and climate vulnerability. Carbon emissions from production lead to output losses, and there is a technology for emissions absorption. We provide an aggregation result: the model with heterogeneity can be cast...

Socio-economic criteria for climate projects have been used in analysing the value of the climate benefit of a reduction in CO2. These reports are optimistic, yet CCS demonstration plants are not implemented as expected. Little attention has been devoted to profitability assessments based on...

Carbon Capture and Storage (CCS) is regarded as one of the most important technologies to mitigate climate change while providing fossil-fuel based energy security. During the past decade, projects in support of the development and deployment of the technology have been initiated across the...

There is a planning gap for CCS projects in Europe. CCS demonstration plants are not implemented as expected. This fact is at odds with optimistic valuation reports that apply socio-economic valuation criteria for climate projects. However, CCS plants are in most cases to be implemented by...

We develop and implement a new method for identifying wasted subsidies, and use it to provide systematic evidence on the misallocation of carbon offsets in the Clean Development Mechanism - the world's largest carbon offset program. Using newly constructed data on the locations and...

We model the value chain of Carbon Capture, transport and Storage (CCS) by focusing on the decisions taking by actors involved in either capture, transport or storage of CO2. Plants emitting CO2 are located along a Salop circle. If these invest in carbon capture facilities, the captured CO2 is...

It is widely recognized that a cost-efficient way to achieve the climate targets of the Paris agreement requires investment in carbon capture and storage (CCS). However, to trigger sizeable investment in CCS the carbon price must exceed the historic carbon prices. This paper examines whether a...

Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or second period. When that cap is tightened the...

The focus of the green paradox literature has been either on demand-side climate policies or on effects of technological changes. The present paper addresses the question of whether there also might be some kind of green paradox related to supply-side policies, i.e. policies that per-manently...
