Promoting Green R&D to Allow Green Products to Outcompete Non-Green Products: Subsidize Consumers or Manufacturers?

Sustainability, Journal Year: 2025, Volume and Issue: 17(3), P. 832 - 832

Published: Jan. 21, 2025

Although green R&D is recognized as an effective approach to achieving sustainability goals, the adoption of technology has not been ideal. As such, many governments support by subsidizing manufacturers’ or consumers’ sustainable purchases. Accordingly, we develop two theoretic models, where a manufacturer engages in compete with competitor who focuses on producing non-green products, and government promotes either (a) consumers (Model C) (b) manufacturers M). Our analysis reveals that implications are quite different from each other. In particular, find although incentive for Model C always lower than M, former scenario enables benefit more subsidy policy. suggest if cares about how affects environmental performance, it should pay attention manufacturers. However, profits subsidize consumers. Finally, be noted hurts more.

Research on the Impact of New Energy Vehicles on Carbon Emissions of Urban Transportation

E3S Web of Conferences, Journal Year: 2025, Volume and Issue: 617, P. 02002 - 02002

Published: Jan. 1, 2025

With the acceleration of urbanization, growth urban travel demand has led to rising carbon emissions, and development low-carbon transport become particularly urgent. This study focuses on prediction emissions in road traffic sector City A 2030, explores potential changes under different scenarios. The research objects include private cars, taxis, buses ordinary trucks, two scenarios are constructed: baseline scenario policy scenario. reflects natural trend future existing technology conditions, while considers implementation new energy vehicle promotion policies evaluates contribution vehicles reducing emissions. multiple linear regression model S-curve used predict total number motor scenarios, “bottom-up” method IPCC is calculate transportation. results show that vehicles, especially pure electric a significant effect field

Design of a carbon footprint-based carbon subsidy impact mechanism for collaborative carbon reduction in new energy vehicle supply chains

Applied Economics, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 16

Published: Feb. 26, 2025

This study constructs a collaborative carbon reduction decision-making model for the supply chain of new energy vehicles under footprint-based subsidy policy. It is found that footprint policy reduces emissions each vehicle in its whole life cycle more than traditional Higher used segment With increase footprint, emission product shows trend increasing and then decreasing. Second, profits manufacturers with policies are smaller those policies. Third, selling price manufacturers' decrease when per unit increased. On other hand, sales, supplier profits, total social welfare unit. Fourth, firms utility products to consumers innovative ability reduce segment.

New energy vehicles are an important tool for the transition to clean and sustainable development. The Nudge Theory is introduced construct a management model conservation carbon reduction in new vehicles. takes into account strategy of reducing or exempting charging fees Through dynamic simulation, we analyze impact considering not on energy-saving effect analysis, it found that (1) constructed by introducing consumer reference optimize fee vehicles, which further enhances saving reduction. (2) consideration boosting can increase consumers’ willingness purchase growth more significant under combined compared with baseline scenario. In strategy, from beginning simulation Scenario 6 end increased 131.74%. (3) terms effects, 3 single has best effect, 9 effect. Compared scenario, number 253.03%, dioxide emissions decreased 38.85%. reach peak 2030, will decrease year year.

Digital infrastructure, as a core component of new plays powerful engine role in driving urban development. It not only profoundly shapes the future landscape cities but also an irreplaceable accelerating dual transition industries toward digitization and greening. This process promotes deep integration synergistic development greening cleverly builds bridge for benefits pollution reduction carbon reduction, laying solid foundation achieving environmentally friendly resource-saving society. study adopt multifaceted approach to explore impact digital infrastructure on management abatement reductions. The coefficient this effect was statistically significant at 1% significance level (0.1056), demonstrating its capacity support reductions both emissions, with regional variations observed. Furthermore, examining factor flows reveals that enhanced labor, capital, innovation flows. Notably, these sectors exhibited coefficients 57.5616, 0.0097, 0.0189 respectively. These findings point nexus between sustainable A nonlinear U-shaped relationship observed joint mitigation reduction. concludes policy recommendations aiming optimize utilization goals.

An Analysis of the Synergistic Effects of Air Pollutant Reduction and Carbon Mitigation in Major Emission Reduction Policies in China’s Transportation Sector

Energies, Journal Year: 2025, Volume and Issue: 18(8), P. 1980 - 1980

Published: April 12, 2025

As of 2023, China’s transportation energy carbon emissions account for over 10%, which has a significant impact on achieving “dual carbon” goals. China successively issued various policies to address pollution in the industry. This study mainly analyzes synergistic effects reduction and measures implemented this We selected 2023 as base year, focused promoting new vehicles (NEVs), advocating bus transit (ABT), advancing rail (ART) three major emission policies, analyzed their air pollutant control greenhouse gas reduction. Based national scale data driving conditions, consumption, factors, reductions gases pollutants brought about by were first calculated. Then, using coordinate system effects, cross elasticity analysis pollutants, normalization evaluation methods, multi capabilities each policy quantified. Quantitative results revealed that NEV substitution achieved CO2 100.966 million tons alongside 1.0196 (CO), 59,506 (NOx), 103,500 (NMHC), 6266 (PM10), 3071 (SO2).
