Environmentally-extended input-output analyses efficiently sketch large-scale environmental transition plans: Illustration by Canada's road industry

چکیده
Industries struggle to build robust environmental transition plans as they lack the tools quantify their ecological responsibility over value chain. Companies mostly turn sole greenhouse gas (GHG) emissions reporting or time-intensive Life Cycle Assessment (LCA), while Environmentally-Extended Input-Output (EEIO) analysis is more efficient on a wider scale. We illustrate EEIO usefulness sketch example of Canada s road industry - estimation national contributions, most important issues, main potential levers sector, and metrics prioritization for green purchase plans). To do so, openIO-Canada, new Canadian database, coupled with IMPACT World plus v1.30-1.48 characterization method, provides multicriteria diagnosis economy. The generates limited impact (0.5-1.8 percent) but must reduce burden from material purchases mainly concrete asphalt products through eco-design invest in machinery powered cleaner energies such low-carbon electricity bioenergies. also captures impacts often neglected process-based pavement LCAs amortization capital goods, staff consumptions, services shows some substantial advocating enlarging system boundaries standard LCA. Yet, construction maintenance only explain 5 percent life cycle carbon footprint network, against 95 roads usage. Thereby, carbon-neutral pathway first focus reducing vehicle consumption wear better design (...)

An Introduction to Environmentally-Extended Input-Output Analysis
Environmentally-extended input-output (EEIO) analysis provides a simple and robust method for evaluating the linkages between economic consumption activities and environmental impacts, including the harvest and degradation of natural resources. EEIO is now widely used to evaluate the upstream, consumption-based drivers of downstream environmental impacts and to evaluate the environmental impact...

Best Upgrade Plans for Large Road Networks
In this paper, we consider a new problem in the context of road network databases, named Resource Constrained Best Upgrade Plan computation (BUP, for short). Consider a transportation network (weighted graph) G where a subset of the edges are upgradable, i.e., for each such edge there is a cost, which if spent, the weight of the edge can be reduced to a specific new value. Given a source and a ...

متن کاملSHREC ’ 14 Track : Extended Large Scale Sketch - Based 3 D Shape Retrieval
Large scale sketch-based 3D shape retrieval has received more and more attentions in the community of contentbased 3D object retrieval. The objective of this track is to evaluate the performance of different sketch-based 3D model retrieval algorithms using a large scale hand-drawn sketch query dataset on a comprehensive 3D model dataset. The benchmark contains 12,680 sketches and 8,987 3D model...
