Hydrogen is a possible alternative to the internal combustion engine, alongside battery-powered vehicles, in the context of reducing greenhouse gas emissions associated with transport activities. The costs associated with hydrogen vehicles are currently high, even when considering the greenhouse gas emissions and other pollutants avoided by their use. Efforts to reduce these costs, which will determine the social and environmental desirability of hydrogen vehicles, face two challenges: the high cost of refuelling, linked to the crucial problem of coordination between development of the vehicle fleet and refuelling infrastructure; and high purchase prices, which may decrease when sufficient quantities generate experience effects. This paper argues that each of these two handicaps calls for a specific policy design: at a local level for coordination between actors, and at a European level to generate sufficient volumes. The example of hydrogen-powered urban buses analysed through the Joint Initiative for Hydrogen Vehicles across Europe (JIVE) offers a telling illustration of these issues.
The cattle sector, both emissions- and land-intensive, represents a great opportunity for mitigation through reforestation. In this paper, we study the efficiency of land-use regulation. Our analytical results indicate that the subsidy is the best alternative policy to emissions tax, provided that the elasticities of land use and emissions to cattle feeding are close. Interestingly,...
The workshop aims to identify the key uncertainties and debates regarding the role of bioenergy in a climate neutral economy, at national and global scales, and the challenges for the design of climate policies. Speakers and precise time will be confirmed soon.
