Bus fleet emissions: new strategies for mitigation by adopting natural gas

Economic and environmental performances of natural gas for heavy trucks: A case study on the French automotive industry supply chain

“…NGV is seen as part of the solution in the city of Delhi (India), where all public transport has been running exclusively on CNG since 2001 (Pal et al, 2009). CNG is a common solution for urban applications such as refuse trucks (Shahraeeni et al, 2015;López et al, 2009) or bus networks, with up to 34% less GHG emissions compared to diesel in the US and Brazil (Galbieri et al, 2018;Shahraeeni et al, 2015;Chandler et al, 2006). However, there is still no large-scale empirical study focused on HDV running on CNG.…”

“…Most studies model the cost breakdown of CNG investment as an extra cost on the purchase and a gap in fuel prices multiplied by a given annual distance (Mouette et al, 2019;Hagos & Ahlgren, 2018b;Hao et al, 2016;Krupnick, 2010). Galbieri et al (2018) studied projected fuel prices by 2035 in Brazil but ignored the tricky transition period, which is key to technology entrenchment, and hence the most likely outcome would be an abandon of natural gas projects, as was the case in Germany (von Rosenstiel et al, 2015), Canada (Flynn, 2002) and New Zealand (Yeh, 2007).…”

“…There is a huge discrepancy between the steady-state carbon price needed to reach environmental targets and the trajectory with a real and constrained starting point. Here, unlike other studies (Galbieri et al, 2018;Krupnick, 2010), we account for the transition period. Thus, the profitability of projects depends on the specific evolution of fuel prices but also on the carbon component specific to each country.…”

Bus Fleet Management – A Systematic Literature Review

“…According to UITP [2], 243 billion transport journeys are made per year in 39 countries, while 63% is by public transport. Even though these numbers stress out the social and economic impact, transit agencies need to evolve beyond the environmental impact [3,4] and move towards the concept of integrated sustainability [5]. Hence, the fleet managers should no longer be solely responsible for routing and scheduling problems; on the contrary, they must rely on performance associated with fuel economy [6], availability [7][8][9], operational efficiency [10,11], life cycle management [12], and pollution [13,14] -highlighting the complexity of decision-making in the BFM domain.…”
