Aiming to attain Net Zero Emission targets while attributing to safety

September 2022
By Amandine Yu


CO2 emissions in the global transport sector amounted to 7.2Gt in 2020.   This accounted for approximately 20% of total global CO2 emissions. While the overall transport market is on the rebound, the transport sector emissions will be required to fall by 20% down to 5.7 Gt by 2030. C02 emissions with the light duty vehicles, the largest sector, will be required to decrease from 3.3 Gt to 1.9 Gt in order to attain the goal of Net Zero Emissions by 2050. 


To meet this scenario’s C02 emissions trajectory, electric vehicles will need to account for 20% of the vehicle stock by 2030. 1,2

Given that the EV industry is still in its early stage of development, there are concerns in being able to achieve this ambitious target. With incidents of fires and explosions being widely reported, the safety of EVs has caught considerable attention. These incidents may have been the result of electrolyte leakage, partial short-circuit or insulation damage in power battery. How to protect batteries from mechanical shock, puncture, heat accumulation while maintaining high energy efficiency while minimizing cost, is a significant challenge for most EV manufacturers.  As an experienced solutions provider of bonding materials, CollTech has dedicated R&D resources to develop reliable and effective solutions to address these challenges.
