Bangladesh’s more than $30 billion textile industries are vital to its economy as generating around 20 percent of GDP and over 80 percent of total export earnings, while employing more than 4.5 million people. But garment factories have become a serious environmental threat for Bangladesh due to unsustainable consumption and production process consuming around 1,500 billion litres of water annually, which aggravates falling ground water levels and contaminating waterways and surrounding environments, which has become a serious threat to human health, food production, and natural environment. Considering these climate threats and unsustainable practices to textile sector in Bangladesh, this research will explore how can promoting local innovation and having transfer of climate technologies for the relevant sector of Bangladesh, the country could transform into climate smart textile production to deliver sustainability and accelerate circular economy and thereby to attain targets of the SDGs (particularly SDGs 1, 12 and 13). The aim of this presentation is to explore how can international climate change law (particularly the Paris Agreement) and intellectual property law (with reference to the World Trade Organizations’ TRIPS Agreement) facilitate climate smart textile production in Bangladesh to deliver sustainability and accelerate circular economy. This presentation would like to shed lights on the potential means for Bangladesh for utilizing international legal mechanisms for the sustainability transitions of the textile sector.
