Greater Dhaka is home to 17 million people and has been experiencing rapid urbanization since its independence in 1971. The population is expected to rise to by roughly 25 million by 2025. With a rising population alongside economic growth, the GHG emissions from the transport sector have been steadily increasing since 2005.
It is estimated that only a fraction of the one million tons of wastewater sludge is processed safely in Uzbek wastewater treatment plants. Around 93% of the wastewater generated by the densely populated Namangan province is discharged with a high risk of leakage to rivers and agricultural areas. As most areas are not connected to any wastewater treatment system, wastewater leakage threatens to contaminate the water, soil and food crops of the region.
The construction industry is currently responsible for more than 23% of the world's greenhouse gas emissions and for 30% of global resource consumption. Maintaining this pattern in this sector, which depends on carbon-intensive machinery and materials, threatens to put the world on a fast track towards a global temperature rise of 3°C or more by 2050 (C40, 2020).
