“…It is important to consider that the transportation industry must switch to electric vehicles in order to reach the climate change targets. For efficient resource use, CE practices like recycling, repairing, and refurbishing are crucial (Richter 2022 ). Batteries can be reused and converted into energy storage devices to increase their lifespan.…”

Concerning rapid resource depletion and the negative effects of climate change, the adaptation of Circular Economy (CE) strategies in the environmental sector is gaining global recognition and application. This study forecasts the energy demand and emissions scenarios for a circular economy-dependent green energy transition, based on learnings from the forced situation caused by the COVID-19 pandemic. This study focuses on the industrial, domestic, and transportation sectors of the National Capital Territory (NCT) of India i.e., Delhi. Implementation of circular economy strategies helps in limiting the impacts of rising energy demand by shifting towards green fuels and biofuels. The data related to energy demand, consumption, percentage share and growth, etc., was gathered and incorporated in Low Emission Analysis Platform model to generate three scenarios i.e., business as usual, circular economy (CE), and pandemic scenario to compare the outputs of energy demand and emissions in terms of CO 2 and particulate matter. The results for the CE scenario, for the year 2020 to 2040 shows that there will be a reduction of 158.2 kt PM 2.5 emissions (24.3%) and 540 Mt CO 2 emissions (49%) as well as a reduction of 203 Mtoe total energy usage (49.3%) as compared to the business-as-usual scenario. The COVID-19 pandemic had a significant impact on societal and commercial activities in the concerned city. Activities came to a standstill during the COVID-19 pandemic, but the same had significantly improved the environment. This unusual forced situation of COVID-19 lockdown produced a unique scenario which shows that the total extra reduction in energy demand of 46%, CO 2 and PM 2.5 emissions of 45–60% could be achieved by 2040, as compared to CE scenario.

“…Therefore, a circular economy approach for LCDs and solar PV panels is urgently needed. A circular economy approach does not only involve recycling, but its strategies also include reuse, repair, restoration, and remanufacturing. , In addition, for an effective circular economy, efforts should be made to engage the private sector, including manufacturers, retailers, and investors, which would stimulate the development of innovative solutions. , …”

Indium has emerged as a strategic metal for high-tech and renewable industries, being catalogued as a critical material to foster a greener future. Nevertheless, its global sustainability is not well addressed. Here, using dynamic substance flow analysis, we study the indium industry evolution between 2010 and 2020 and estimate its future demand in the medium and long term toward 2050 to identify potential paths and mechanisms to decrease indium losses and to identify the key stages in its life cycle. As electronics and photovoltaic industries will play a crucial role in the indium demand, we assess their indium demand employing three cumulative photovoltaic capacity scenarios (8.5, 14, and 60 TW by 2050) with different dominant photovoltaic sub-technologies. Results show that liquid-crystal displays and photovoltaic panels will drive indium future demand, increasing its current demand by 2.2–4.2, 2.6–7.0, and 6.8–38.3 times for the 8.5, 14, and 60 TW scenarios, respectively, threatening with shortages that could occur as early as the next decade. Therefore, measures to reduce losses in primary production, innovations and improvements in electronics and solar panels, and indium recycling with an effective circular economy strategy could promote and secure the future sustainability of indium.

“…These trends will affect the pathways towards decarbonization of passenger car travel, including changes in charging patterns 13 , cost structures 9 and the value of travel time [42][43][44] , which may induce additional travel activity 45 and cause modal shifts 46,47 . These trends may also cause changes in vehicle design, including materials used in manufacturing 48 and changes to facilitate material recycling 49 , but many of these aspects are yet to materialize.…”

“…Our analysis shows that the relationship between vehicle lifetime and driving intensity is an important factor when estimating the carbon footprint of shared mobility. Some analysts argue that passenger cars in today's fleets are not being used enough to compensate for material use and emissions during the manufacturing phase 49,50 . Therefore, increasing the driving intensity, for example through shared autonomous BEVs, may be an option for reducing lifecycle emissions from passenger car travel.…”

Shared mobility and vehicle lifetimes – implications for the carbon footprint

Car sharing will likely increase the annual vehicle driving distance, which may accelerate passenger car retirement. We develop a semi-empirical lifetime-driving intensity model using statistics on Swedish vehicle retirement. We integrate our semi-empirical model with a carbon footprint model, which assesses future decarbonization of global, European Union, and Swedish energy systems. In this work, we show that the carbon footprint depends on both calendar age and cumulative driving distance of the vehicle. Higher driving intensities generally result in lower carbon footprints due to increased cumulative driving distance over the vehicle’s lifetime. Shared autonomous vehicles could decrease the carbon footprint by about 41% in 2050, if one shared vehicle replaces ten individually owned vehicles. However, empty travel by shared autonomous vehicles – the additional distance traveled to pick up passengers – may cause carbon footprints to increase. Hence, vehicles should be designed for durability to enhance the carbon footprint benefits of sharing.
