What is the largest embodied carbon flow in the global PV trade?

The largest regional embodied carbon flows in the global PV trade are the intra-East Asia flow and the flow from East Asia to Southeast Asia, reaching 31.23 MtCO 2 e and 18.44 MtCO 2 e, respectively. The largest intercountry flow is from China to India (7.96 MtCO 2 e).

How much carbon does PV produce?

Carbon emissions embodied in the global PV product trade are estimated to be 128.35 million tons of carbon dioxide equivalent (MtCO 2 e) in 2017, accounting for 0.38% of worldwide fossil fuel combustion carbon emissions in the same year 58.

How can shared PV and ESS tracing be achieved based on carbon quota?

And based on the carbon emission contribution of each power source to each load, the CEF tracing and tracking can be achieved. A low-carbon allocating method of shared PVs and ESSs on the demand side, based on carbon quota mechanism, is proposed, in which all customers serve as the investors.

Why is the global solar PV product trade important?

The global solar PV product trade plays an important role in facilitating PV product production and utilization and in mitigating climate change. Traded solar cells and modules in 2017 could generate 2325.25 TWh of electricity over their 30-year lifetimes.

Does the global PV product trade contribute to global public goods?

The present study clarifies that, although the global PV product trade is accompanied by carbon emissions “migration”, emissions embodied in the global PV product trade are small compared with the substantial emissions reduction potential that this type of trade can contribute to global public goods by helping to avert climate crises.

Which countries export the most carbon embodied in PV products?

East Asia is the largest exporter region of carbon embodied in PV products, at 79.35 MtCO 2 e in 2017, accounting for 61.83% of the global total. China and Japan are the top 2 carbon outflow countries, aggregately accounting for 43.85% of the global total.
