Recent research has shed light on the cost-effective contribution that agriculture can make to global greenhouse gas abatement; however, the resulting impacts on agricultural production, producer livelihoods, and food security remain largely unexplored. This paper provides an integrated assessment of the linkages between land-based climate policies, development, and food security, with a partic...

This paper reviews ways of reducing surface transport noise by natural means. The noise abatement solutions of interest can be easily (visually) incorporated in the landscape or help with greening the (sub)urban environment. They include vegetated surfaces (applied to faces or tops of noise walls and on buildings’ façades and roofs), caged piles of stones (gabions), vegetation belts (tree belts...

This paper examines the investment strategies of regulated companies in irreversible abatement technologies and the environmental achievements of the system in an inter-temporal cap–and–trade market using laboratory experiments. The experimental analysis is performed under varying market structures: firstly, in a market where there are exclusively regulated companies and then in a market with t...

In this study we use historical emission data from installations under the European Union Emissions Trading System (EU ETS) to evaluate the impact of this policy on industrial greenhouse gas emissions during the first two trading phases (2005-2012). As such the analysis seeks to disentangle two causes of emission abatement: that attributable to the EU ETS and that attributable to the economic c...

This paper focuses on a type of voluntary pollution abatement agreement (VA) in which the regulator offers regulatory relief for the participating firm in exchange for environmental improvements. If the regulator does not have statutory authority to provide regulatory relief, the VA can leave the firm more vulnerable to legal challenges through citizen lawsuits. I use a model of negotiated VAs ...

This study examines whether policies to encourage cattle ranching intensification in Brazil can abate global greenhouse gas (GHG) emissions by sparing land from deforestation. We use an economic model of global land use to investigate, from 2010 to 2030, the global agricultural outcomes, land use changes, and GHG abatement resulting from two potential Brazilian policies: a tax on cattle from co...

This study uses the GAINS model framework to estimate current and future emissions of the fluorinated greenhouse gases HFCs/HCFCs, PFCs and SF6 (F-gases), their abatement potentials and costs for twenty source sectors and 162 countries/regions, which are aggregated to produce global estimates. Global F-gas emissions are estimated at 0.95 Pg CO2eq in 2005 with an expected increase to 3.7 Pg CO2e...

Many studies have been done on various properties of dust and one of the most important characteristics of dust is the ability to carry different microorganisms from the source points. The aim of this study was to investigate the bacterial and fungal community of dust and to identify its dominance species in a single event of intense dust storm, in the northern regions of Sistan and Blauchestan...

In this study we evaluate the profitability of nutrient abatement measures in eutrophied coastal areas exposed to a risk of frequent oil spills. The case studied is the Gulf of Finland, which forms part of the Baltic Sea. We present a dynamic model that integrates land loads of nitrogen and phosphorus, cost of nutrient abatement measures in agriculture, nutrient dynamics in the sea basins adjoi...

This paper analyzes the impact of environmental policy instruments on the choice of pollution control techniques. I ̄rst recast the existing theoretical model of pollution abatement technology choice. Previous studies have found that the cost savings to a ̄rm that adopts a technical innovation in pollution control are greater under a market-based instrument, such as an emissions tax or tradeabl...
