📋 Tender Overview
Scope :
The peoples republic of china (prc) is shifting its growth target away from quantity and toward quality and sustainability, adopting a green and low-carbon development path to tackle climate change and address environmental degradation. the prc committed (i) its nationally determined contributions that aim for carbon dioxide (co2) to peak before 2030 and achieve carbon neutrality before 2060, and (ii) a strategy for climate change adaptation. responding to these national-level commitments and strategies, governments at provincial, municipal, and district-level have formulated their own plans, programs, and strategies to contribute to national government targets and results.
chongqing is a centrally administered municipality developed as one of the main industrial bases of the inland prc. a large portion of chongqings gross domestic product is derived from the secondary sector, and the share of heavy industries in the economy is high. its resource-based and polluting economy is impacting the environment. chongqing is facing challenges in transforming itself into a green and low-carbon economy. furthermore, chongqing has been experiencing severe climate events, including extreme high temperatures, mountain fires, heavy rains, floods, and droughts. responding to the national-level targets and strategies, chongqing has plans to actively respond to climate change, demonstrate low-carbon cities and communities, advocate green lifestyles, innovate institutional mechanisms to realize low-carbon cities, reduce pollution, and increase climate resilience and disaster responsiveness in urban and rural areas.
chongqing gaoxin district (cgd), one of the chongqings districts with an area of 316 square kilometers (km2), is situated in the liangtan river basin between two mountain ranges with rivers, lakes, wetlands, and green spaces. by mid-2023, cgds population was around 575,000, about 86% of which are urban residents. this is chongqings primary strategic development area-home to a national-level high-tech zone with enterprises and education and research institutions.
although urban infrastructure was developed with the rapid urbanization of cgd, it is of poor quality, resulting in negative consequences. the nonrevenue water rate is substantial, and combined sewer systems pose pollution risks during heavy rain season. peoples awareness of sorting and reusing domestic garbage and building materials still needs improvement. many of cgds buildings are still not energy efficient, and their energy consumption and carbon emissions are high and need improvement. about 18% of the co2 emissions of cgd in 2021 were produced from peoples daily activities. residents, including women, are concerned about the air quality deterioration.
chongqing and cgd strive to address environmental degradation through ecology and river rehabilitation. pollution sources are not effectively controlled--the water quality of liangtan river and its tributaries fluctuates depen
