The Belt, the Road, and the carbon emissions in China

This paper explores the effect of the Belt and Road Initiative (BRI) on China's exports and the domestic carbon emissions induced by the exports. We employ a decomposition framework to assess the driving factors of the change of CO₂ emissions induced by China's exports to different destinations and evaluate the main contributions of the gap between the BRI countries and non-BRI (NBRI) countries. The decomposition results show that while the scale effect was the dominant force behind the pre-BRI emission growth, the contribution of the composition effect became more prominent after the inception of the Initiative. Our econometric analysis suggests that the Initiative leads to an increase in the share of carbon-intensive products in China's exports to the BRI countries by nearly 5 percentage points, which is approximately one quarter of the share of carbon-intensive exports to the BRI countries. A further investigation reveals that China's international project contracting is the main channel that has resulted in the increase of the share of carbon-intensive exports in China's exports to the BRI countries.
