“…It is recognized that the actual likely climate changes may be larger than those indicated by the SD-PCU scenario because we assume, for simplification, that conventional and nonconventional fossil fuels have the same emission factors, while some of the literature indicates that the GHG footprint of the various non-conventional fossil fuel resources are 11 higher than for the equivalent conventional resources Weber and Clavin, 2012;Mckellar et al, 2009;Brandt and Farrell, 2007 ). For example, claimed that life-cycle GHG emissions from shale gas are at least 30% more than those from conventional gas.…”

Climate projections are based on emission scenarios. The emission scenarios used by the IPCC and by mainstream climate scientists are largely derived from the predicted demand for fossil fuels, and in our view take insufficient consideration of the constrained emissions that are likely due to the depletion of these fuels. This paper, by contrast, takes a supply-side view of CO 2 emission, and generates two supply-driven emission scenarios based on a comprehensive investigation of likely long-term pathways of fossil fuel production drawn from peer-reviewed literature published since 2000. The potential rapid increases in the supply of the non-conventional fossil fuels are also investigated. Climate projections calculated in this paper indicate that the future atmospheric CO 2 concentration will not exceed 610 ppm in this century; and that the increase in global surface temperature will be lower than 2.6 o C compared to pre-industrial level even if there is a significant increase in the production of non-conventional fossil fuels. Our results indicate therefore that the IPCC's 2 climate projections overestimate the upper-bound of climate change. Furthermore, this paper shows that different production pathways of fossil fuels use, and different climate models, are the two main reasons for the significant differences in current literature on the topic.

“…Many studies examine the GHG emissions of single oil sources production like oil sands, oil shale, CTL, GTL, shale gas, natural gas, coal, petroleum, unconventional gas, and natural gas from shale formations, [40][41][42][43][44][45] but there is little literature making a comparison between them. Th e comparability of the GHG emissions from the diff erent oil sources is very diffi cult, as the evaluation of different studies on unconventional fossil fuel resources in EROI studies disclose also price developments.…”

Our report analyzes the substitution of marginal oil with biofuels. For that, we evaluate the effects that influence the substitution process in the short, mid and long term. We identify OPEC, resource nationalism, and geopolitical issues as important influence factors and arrive at the conclusion that in the short term biofuels will replace mainly OPEC oil but not the most expensive petroleum. In the medium and long term biofuels will replace the most expensive petroleum because OPEC production cuts are only possible on a temporary basis and in restricted quantities. Our comparison of the costs of the different fossil fuels with their greenhouse gas emissions shows that there is no direct correlation between the level of greenhouse gas emissions and production costs. However, we see strong evidence every time that the marginal oil gets more carbon‐intensive and that biofuels will increasingly displace these carbon‐intensive fossil fuels. That is shown especially in the increase of unconventional fossil fuels and new frontier oil (Amazon, deep‐sea, etc.). The investments in these technologies are very price‐sensitive, like the financial crisis 2008/2009 has showed. Further evidence brings the decline of the energy return on investment (EROI) of the oil production worldwide and the increase of the marginal oil costs from 25 to almost 100 dollars/barrel in the last 10 years. We expect that the increase of the carbon intensity of marginal oil will further enlarge the climate effects of global petroleum production. Marginal oil as an indirect effect of the biofuel use should therefore get the same significance value as indirect land‐use change (ILUC) in the current climate protection debate. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd
