Climate Action Tracker (CAT), an independent scientific analysis that tracks climate action across 32 countries covering around 80 % of global emissions, has some good news about India. It believes India will overachieve its climate action targets submitted under the Paris Agreement on climate change – a broad consensus that 195 countries had arrived at in 2015 to legally ratify action to lower emissions through the United Nations Framework Convention. Leaders aimed to limit the long-term rise in average world temperature to 2° C.
Clearly, meeting that target wouldn’t be easy to achieve unless drastic and difficult measures are initiated. And we’ve seen the government taking some harsh decisions in recent times, ably supported by the automotive sector. CAT is appreciative of the current policies implemented by the government in the country, and believes India will become a global climate leader in due course.
At the core of this movement is the industry’s drive towards cleaner mobility – primarily through electric and hybrid propulsion, and upgrading existing internal combustion engines to meet the most stringent emission regulations under the Bharat Stage VI norms. While every stakeholder in the electromobility value chain believes EVs are the future of mobility, large-scale adoption of EVs in India is fraught with challenges. Many experts question India’s preparedness to shift from oil to lithium as an energy source. The dependency on hydrocarbon liquid fuels may continue for a few more decades, they say.
Such claims are proven by the numerous new discoveries made by researchers and engineers globally. There’s constant improvement in the areas of combustion, air intake technology and fuel injection technology, for instance. There is work happening in the area of engine design architecture, cold starting issues, after-treatment mechanisms and NOx treatment. We also have examples of how the use of 48 V mild hybrid system on a diesel engine helps bring down fuel consumption and CO2 emissions, while also reducing NOx emissions by 60 %.
In this edition focused on IC engines, we have a fantastic article that takes a detailed look at GHG life cycle comparison of internal combustion and BEVs. Moreover, there are articles on coasting as a real driving function, and the use of hydrogen as a fuel for combustion engines, apart from our regular sections. Hope you enjoy reading this one!
