Climate change & carbon budgets: the contribution of international transport emissions

摘要: For global mean temperatures to remain below the 2C threshold, annual emission reductions of an unprecedented scale are required over coming decades. Yet, even within industrialising nations, two sectors in particular, international aviation and shipping, anticipate a medium-term continuation emissions growth. At analysis, it is unimportant which reduce their emissions, as long relevant carbon budget not exceeded. In this regard, those with lowest abatement costs likely compensate for significant technological socio-economic barriers reduction. Yet growth anticipated without step changes short-term, places additional pressure on other mitigate. Given overarching climate change challenge, paper explores available space shipping given managerial efficiency intensity improvements transport rates. The results illustrate necessity urgent effective policies mitigation if target achievable goal.
