Energy Use and Carbon Footprint for Potable Water Treatment in Haiderpur Water Treatment Plant, Delhi, India

Abstract

With the advent of the environmentally conscious decision-making period, the carbon footprint of any engineering project becomes an important consideration. Despite this, the carbon footprint associated with water resource projects is often overlooked. Water production, its supply and treatment processes involve significant energy consumption and thus, are source of emissions of greenhouse gases (GHGs) such as carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) which contribute to global warming. The emissions are not direct but come as a by-product of burning of fossil fuels to produce electricity to carry out these processes. Since water demand is continuous and keeps on rising, the quantification of carbon footprint associated with the water industry is vital. This paper studies and attempts to quantify the carbon footprint of one such urban water system, that is the Haiderpur Water Treatment Plant in Delhi, capital region of India by using the Life Cycle Assessment methodology and evaluate its performance from the point of view of energy consumption and make suggestions.

Shaping India's climate future: A perspective on harnessing carbon credits from agriculture

“…Nonetheless, the recently announced framework on VCM in Indian agriculture and schemes such as the Green Credit Program, Promotion of Alternate Nutrients for Agriculture Management Yojana (PM-PRANAM), and the Mangrove Initiative for Shoreline Habitats and Tangible Incomes (MISHTI) among others, incentivize green growth (Ministry of Agriculture and Farmers Welfare, 2024; Gazette of India, 2023; Press Information Bureau, 2023). Furthermore, regular consultations with carbon farming stakeholders including project developers, certifiers like VERRA and the Gold Standard, international agricultural R&D organizations, the Integrity Council for the VCM, the Carbon Market Association of India, and carbon credit rating agencies can facilitate holistic policy formulation (Singh and Chaturvedi, 2023). 4…”

“…This disparity could be accredited to biophysical variations that must be considered (Chavan et al, 2023). Furthermore, cultural barriers like lack of stakeholders’ awareness, personal interest, and attitude cause apprehensions about carbon farming (Singh and Chaturvedi, 2023; Sharma et al, 2021). In developing countries, especially in Africa and South Asia, women are often excluded from decision-making in agriculture due to intrinsic gender inequality (Lee et al, 2015; Raghunathan et al, 2019).…”

Air quality and health co-benefits of climate change mitigation and adaptation actions by 2030: an interdisciplinary modeling study in Ahmedabad, India

“…While A/C saves lives, its use can worsen both air pollution and climate change itself, if the energy to meet associated increases in electricity demand is supplied from fossil fuels (Abel et al 2018 ). India operates 47 thermal coal-fired power plants more than 25 years old, with an average age of 34 years (Singh and Sharma 2021 , Global Energy Monitor 2022 ), including the torrent power plant (TPP) in Ahmedabad, opened in 1934. Prior work estimated that in India, air pollution from coal combustion in thermal power plants and industries contributes to 169 000 premature deaths annually (Ganguly et al 2020 ).…”
