Greenhouse Gas Emissions

Question

To ask His Majesty's Government why they do not publish data on greenhouse gas emissions embedded within the supply chain of (1) energy intensive goods, (2) car batteries, and (3) solar panels, imported into the UK.

Answer

Defra publishes annual data on greenhouse gas emissions embedded within goods and services imported into the UK here (see attached) as part of the UK and England’s Carbon Footprint.

Because of the methodology used, Defra does not hold data on these emissions at an individual product level, so the department is unable to publish estimates of greenhouse gas emissions embedded specifically within the supply chains of energy intensive goods, car batteries, and solar panels, imported into the UK.

For further information, a methodology document is published alongside the UK and England’s Carbon Footprint statistics here (see attached).
