An Evaluation of Integrated Climate Protection Policies for the United States Ecology and Society
Bernow, Stephen; Tellus Institute; sbernow@tellus.org; Duckworth, Max; Tellus Institute; maxd@tellus.org.
This paper presents and discusses an integrated set of policies designed to reduce U.S. carbon emissions over the next four decades. This innovation path also aims to promote environmental quality, particularly by reducing emissions of criteria air pollutants, to reduce U.S. dependence on imported oil, and to induce technological innovation and diffusion in energy production and consumption. The innovation path would reduce economy-wide carbon emissions by 26% below baseline projections for 2010 and by 62% below baseline projections for 2030; this translates into 10% below 1990 levels in 2010 and 45% below 1990 levels in 2030. Emissions of criteria pollutants also would be significantly reduced, as would petroleum imports by the United States. Moreover,...

Carbon Labeling for Consumer Food Goods AgEcon
Shewmake, Sharon; Okrent, Abigail M.; Thabrew, Lanka; Vandenbergh, Michael.
We construct a model to predict how consumers will respond to better information about the carbon content of 42 foods and a nonfood composite as well as product categories through a label, and provide guidance as to what kinds of goods would provide the highest CO¬2eq emission reductions through a labeling scheme. Our model assumes that consumers value their individual carbon footprint, allowing us to utilize estimates of own- and cross-price elasticities of demand from the literature on demand analysis. We make three different assumptions about how consumers currently value their carbon footprint and find that when a label informs consumers, their baseline perception matters. We also find that carbon labels on alcohol and meat would achieve the largest...

Curtailing Fertilizer Scarcity and Climate Change; an appraisal of Factors Affecting Organic Materials Use Option in Nigeria’s Agriculture AgEcon
Omotesho, O.A.; Fakayode, S.B.; Tariya, Y..
Global trends nowadays towards long term sustainable crop production is hinged on either supplementing the use of chemical fertilizers with organic materials or a complete use of organic materials. This is more so since substituting chemical fertilizers with organic materials reduces the risks of exposure to ailments that arise on account of synthetic compounds and increases farmers’ gains via reduced soil erosion and carbon emissions and increased bio-diversity. In this vein, the current study investigated organic materials use in Nigeria’s agriculture. Specifically, the study examined availability and use of chemical fertilizer and organic materials substitutes and investigated factors affecting the use of organic materials in the Nigerian food sector....

Early Emissions Reduction Programs: An Application to CO2 Policy AgEcon
Parry, Ian W.H.; Toman, Michael.
In the wake of the December 1997 Kyoto Protocol, which, if implemented, would oblige the United States and other industrialized countries to reduce greenhouse gases (GHGs) by 2008-2012, a number of proposals have been offered to increase the incentives for reducing emissions over the nearer term. The existence of an interim period between setting and implementing environmental goals is ubiquitous in environmental policymaking. The existence of this interim period gives rise to several potential rationales for early emissions reductions. In this paper we use a series of simple models and numerical illustrations to analyze some aspects of the performance of early emissions reduction programs in the case of GHGs. We show that there is a compelling economic...

Forest carbon emissions from cropland expansion in the Brazilian Cerrado biome. Repositório Alice
NOOJIPADY, P.; MORTON, D. C.; MACEDO, M. N.; VICTORIA, D. de C.; HUANG, C.; GIBBS, H. K.; BOLFE, E. L..
Abstract. Land use, land use change, and forestry accounted for two-thirds of Brazil?s greenhouse gas emissions profile in 2005. Amazon deforestation has declined by more than 80% over the past decade, yet Brazil?s forests extend beyond the Amazon biome. Rapid expansion of cropland in the neighboring Cerrado biome has the potential to undermine climate mitigation efforts if emissions from dry forest and woodland conversion negate some of the benefits of avoided Amazon deforestation. Here, we used satellite data on cropland expansion, forest cover, and vegetation carbon stocks to estimate annual gross forest carbon emissions from cropland expansion in the Cerrado biome. Nearly half of the Cerrado met Brazil?s definition of forest cover in 2000 (?0.5 ha with...

Forest Cover Changes in Tropical South and Central America from 1990 to 2005 and Related Carbon Emissions and Removals. Repositório Alice
EVA, H. D.; ACHARD, F.; BEUCHLE, R.; MIRANDA, E. E. de; CARBONI, S.; SELIGER, R.; VOLLMAR, M.; HOLLER, W. A.; OSHIRO, O. T.; ARROYO, V. B.; GALLEGO, J..
This paper outlines the methods and results for monitoring forest change and resulting carbon emissions for the 1990-2000 and 200-2005 periods carried out over tropical Central and South America. To produce our forest change estimates we used a systematic sample of medium resolution satellite data processed to forest change maps covering 1230 sites of 20 km by 20 km, each located at the degree confluence. Biomass data were spatially associated to each individual sample site so that annual carbon emissions could be estimated. For our study area we estimate that forest cover in the study area had fallen from 763 Mha (s.e. 10 Mha) in 1990 to 715 Mha (s.e. 10 Mha) in 2005. During the same period other wooded land (i.e., non-forest woody vegetation) had fallen...

How Ambitious are China and India’s Emissions Intensity Targets? AgEcon
Stern, David I.; Jotzo, Frank.
As part of the negotiating process for a post-Kyoto climate policy regime, several developing economies have announced carbon emission targets for 2020. China and India’s commitments are framed as emissions intensity reductions by 40 to 45 per cent and 20 to 25 per cent respectively between 2005 and 2020. But how feasible are these proposed emissions intensity reductions, and how do they compare with the targeted reductions in the United States and the European Union? In this research report we use a stochastic frontier model to explain the variation in countries’ energy intensities. We use the model to produce emissions projections for China and India under a number of scenarios that consider various rates of technological change and changes in the...

Modelling the Global Diffusion of Energy Efficiency and Low Carbon Technology AgEcon
Stern, David I..
The aim of this study is to measure and understand the long-term factors behind trends in energy and carbon intensity in different economies. It also looks at how improvements in energy efficiency are spread to countries around the world. Of particular interest is the rate at which efficiency improvements spread from developed to developing countries and what affects this diffusion. Countries that are considered are Australia, major European economies, USA, Canada, Mexico, Japan, China, and India.

Should Corporate Average Fuel Economy (CAFE) Standards Be Tightened? AgEcon
Parry, Ian W.H.; Fischer, Carolyn; Harrington, Winston.
This paper develops analytical models to estimate the welfare effects of higher Corporate Average Fuel Economy (CAFE) standards on new passenger vehicles. The analysis incorporates a broad range of fuel-and-driving-related externalities, fuel taxes, different assumptions concerning consumers' valuation of fuel saving technologies and their alternative value in enhancing other vehicle attributes, and endogenous vehicle fleet composition. To implement the analysis, we develop estimates of CAFE's impact on local pollution, nationwide congestion, and traffic accidents. We find that higher fuel economy standards can produce anything from moderate welfare gains, to very little or no effect, to substantial welfare losses, depending on how consumers value fuel...
