Reducing global CO 2 emissions with the technologies we have

Abstract

The energy intensities of the various industrial sectors differ considerably across countries. This suggests a potential for emissions reductions through improved accessibility to efficient technologies. This paper estimates an upper-bound CO2 emission mitigation potential that could theoretically be achieved by improved access to efficient technologies in industrial sectors. We develop a linear optimization framework that facilitates the exchange of sectoral production technologies based on the World Input-Output Database (WIOD), assuming perfect substitutability of technologies and homogeneity within economic sectors, while ignoring barriers to technological adoption and price driven adjustments. We consider the full global supply chain network and multiple upstream production inputs in addition to energy demand. In contrast to existing literature our framework allows to consider supply chain

Tourism, the environment, and energy policies

The effect of industry delocalization on global energy use: A global sectoral perspective

“…Such mitigation strategies might be 20 particularly feasible for manufacturing sectors, which are both prone to delocalization, responsible for a large share of energy consumption and show large efficiency variations across countries (Kim and Kim, 2012;Saygin et al, 2011). Given that manufacturing sectors also imply significant energy consumption in their supply chains, targeting selected energy intensive sectors might imply significant reductions in both, energy consumption and emissions in upstream sectors (Ward et al, 2017).…”

An integrated gas-oil and bio-diesel supply network model with strategic and tactical applications considering the environmental aspects

“…Rising pollution, declining fossil fuels, environmental concerns, economic development, climate change, the food crisis, and fuel price fluctuations have posed serious challenges for energy planning and management [1]. In recent years, on the one hand, issues such as energy security and countries' dependence on fossil fuels that end one day, and on the other hand, crises caused by environmental pollution have shifted countries to alternative sources that address the above two challenges [2]. Experts have examined alternative sources that are both renewable and cleaner.…”
