Emissions intensity comparisons and consumption-based CO2 accounting of transportation services

As the international division of labour becomes more entrenched, distance goods travel before they reach final consumer increases; at least this was case outbreak COVID-19 pandemic. International trade and cross-border cargo movements generate significant carbon emissions. Despite theoretical advances, empirical studies frequently draw contradictory conclusions influence on a country’s decarbonization efforts is inconclusive. This study examines emissions caused by countries’ transportation services global value chains. The input–output (IO) model 2015 multi-regional environmental table from UNCTAD-Eora database are employed. approach used to determine generated transport sector, along chains, in 190 countries. Environmentally extended IO analysis then reallocates responsibilities sector production consumption. identifies which sectors add or emit CO2. Our findings indicated that: (1) industry country may have detrimental effect environment while generating minimal economic benefit; (2) be tightly related chain operations, but does not create considerable impact. Given differences intensity, we propose only calculating production-based accounting (PBA) CO2 emissions, also consumption-based (CBA). If CBA lower than PBA carbon-leakage credit. top three countries with highest credit for were China, Russia USA. taken into consideration, some nations cease possess comparative advantage manufacturing trade.
