BACKGROUND The introduction of renewable jet fuel (RJF) is considered an important emission mitigation measure for the aviation industry. This study compares the well-to-wake (WtWa) greenhouse gas (GHG) emission performance of multiple RJF conversion pathways and explores the impact of different co-product allocation methods. The insights obtained in this study are of particular importance if R...

Economic analysis of emission permit markets, and particularly of the initial permit allocation, have concentrated largely on static approaches. This is somewhat unsatisfactory as the allocation method in subsequent commitment periods may influence the behaviour of the market participants in the current period. For instance, some advocate a system of “rolling grandfathering”, in which later per...

to date, the effects of nanoparticles on woody plants remain unaddressed. this study reveals some of the physiological and biochemical effects of sio2 nanoparticles on wild pear seedlings. the seedlings were irrigated with different concentrations of nano silica (0, 10, 100, 500 and 1000 mg/l) for 14 days. nanoparticle adsorption and absorption, biomass allocation, gas exchange, relative water ...

The introduction of a price on carbon dioxide will have important effects on the U.S. economy, and especially important effects on the electricity sector, which currently accounts for about 40 percent of carbon dioxide emissions. This paper examines alternative approaches to the distribution of allowance value to the sector, including free allocation to consumers through electricity and natural...

Explicit algebraic equations for calculation of wind and stack driven ventilation were developed by parametrically matching exact solutions to the flow equations for building envelopes. These separate wind and stack effect flow calculation procedures were incorporated in a simple natural ventilation model, AIM-2, with empirical functions for superposition of wind and stack effect and for estima...

This paper presents a case study of using oil ®ngerprinting technology to correctly back allocate commingled pipeline crude to production from six contributing ®elds in an o€shore southeast Asia basin. A large number of oil and pipeline samples were collected over time and analyzed by gas chromatography for their oil ®ngerprints. In this case, production from each ®eld pipeline could easily be ...

An auction of carbon permits is the best way to achieve carbon caps set by international negotiation to limit global climate change. To minimize administrative costs, permits would be required at the level of oil refineries, natural gas pipe lines, liquid sellers, and coal processing plants. To maximize liquidity in secondary markets, permits would be fully tradable and bankable. The government...
