Recently, NITI Aayog has released a report titled-Towards Decarbonising Transport 2023.

  • The report serves as a comprehensive resource for assessing the current status and developments in the transport sector, with a focus on G20 nations and their climate commitments.

What is Decarbonising Transport?

Decarbonizing transport refers to the process of reducing or eliminating the carbon emissions associated with the transportation sector. The goal is to make transportation more environmentally friendly and sustainable by reducing its carbon footprint.

This involves several key strategies:

  • Transition to Clean Energy: Decarbonizing transport often involves shifting from fossil fuels, such as gasoline and diesel, to cleaner energy sources like solar electricity, hydrogen, or biofuels.
  • Improving Fuel Efficiency: Another approach is to make traditional internal combustion engine vehicles more fuel-efficient, reducing the amount of carbon dioxide (CO2) emissions per mile traveled.
  • Public Transportation and Active Transportation: Promoting the use of public transportation, walking, and cycling can reduce the number of individual vehicles on the road, leading to lower emissions.
  • Multi-Modal Transportation: Encouraging a combination of transportation modes, such as combining cycling with public transit, can reduce the overall carbon footprint of travel.
  • Infrastructure Development: Building infrastructure for electric vehicle charging stations, hydrogen refueling, and alternative fueling options is critical to support the transition to cleaner energy sources.
  • Policy and Regulation: Setting emissions standards, providing incentives for clean energy vehicles, and implementing congestion pricing to encourage more sustainable transportation choices.

Need 

  • Despite global action to keep global warming well below 2°C target, transport emissions continue to grow, which is why the efforts of G20 countries to decarbonise the sector are so important.
  • Globally, the transport sector contributes about 25% of CO₂ emissions from fuel combustion and 15% of Greenhouse Gas (GHG) emissions.
    • According to the latest The International Transport Forum report, by 2050 CO₂ emissions from transport will increase by 16%, even if today’s political commitments are fully implemented
  • A strong increase in transport demand is expected to offset policy-led emissions reductions.

What are the Current National and International targets in Transport Decarbonization?

Global Commitments:

  • Zero-emission cars : Signatories from both industrialized and emerging economies committed to achieving 100% zero-emission cars and vans by 2035-2040.
  • Net-Zero Pledges to transportation : COP26 resulted in an unprecedented number of net-zero pledges and commitments related to transportation, including the Declaration on Accelerating the Transition to 100% Zero-Emission Cars and Vans
  • Transport Targets in NDCs: 41% of second-generation NDCs include transport-related targets, covering both greenhouse gas (GHG) mitigation goals and non-GHG objectives.
    • Nationally Determined Contributions (NDCs) under the Paris Agreement are essential for climate mitigation. The second round of NDC submissions concluded in 2021, with COP26 calling for updates and a third round beginning in 2025

What is the significance of G20 Countries in Transport Decarbonisation?

  • Major Political and economic contributors:
    • G20 countries are home to over 4.7 billion people, accounting for 62% of the global population. By 2050, approximately half of the world's population is expected to reside in G20 nations.
    • G20 countries collectively account for almost two-thirds of the world’s population, around 80% of global economic output, nearly 75% of global exports, and more than 80% of current global CO₂ emissions.
  • High Urbanization:
    • G20 nations are highly urbanized, with a substantial percentage of the population living in cities. Per capita emissions in G20 countries are significant and will continue to have a disproportionate impact on global emissions.
      • For instance, in Argentina, 92% of the population resides in urban areas.
    • The G20 collectively produces around 80% of global economic output, nearly 75% of global exports, and is responsible for over 80% of current global CO₂ emissions.
  • Major Carbon Emitter :
    • G20 countries are responsible for nearly 70% of worldwide transport emissions, emitting around 5.8 billion metric tons of CO₂ from fuel combustion.
    • Transport emissions are closely tied to economic prosperity, the movement of people and goods, and have been a persistent challenge. Globally, the transport sector contributes about 25% of CO₂ emissions from fuel combustion and 15% of Greenhouse Gas (GHG) emissions.
    • CO₂ emissions since 1990, they still contribute two-thirds of these emissions.
    • Despite the COVID-19 pandemic's impact on emissions, it did not significantly alter the overall share of transport emissions from previous years.
  • Growth in Transport Emissions:
    • Transport emissions have seen a substantial increase, with a 64% rise in G20 countries and a 79% increase worldwide since 1990
    • Between 2015 and 2019, G20 countries saw a 6% increase in transport-related emissions, indicating the persistent challenge of reducing emissions in the sector.

What are the Challenges Faced by Individual G20 Members in achieving Transport Decarbonization?

  • Infrastructure and Investment:
    • Developing and upgrading transportation infrastructure to support sustainable and low-carbon modes of transport, such as electric vehicles (EVs), requires substantial investments in charging or refueling stations, public transportation systems, and sustainable urban planning.
  • Technological Adoption:
    • Encouraging the adoption of cleaner and more efficient transport technologies, like electric vehicles, can be hindered by factors such as high initial costs, limited availability, and consumer reluctance to switch from traditional fossil-fueled vehicles.
  • Regulatory Frameworks:
    • Establishing and implementing effective policies and regulations to incentivize cleaner transport options and penalize high-emission vehicles is often met with resistance from industry stakeholders and requires political will and public support.
    • G20 members face contesting challenges in achieving socio-economic transformation, especially in the remaking of the transport sector.
  • Energy Transition:
    • Transitioning to renewable energy sources for transportation, such as clean electricity or sustainable biofuels, can be challenging due to the existing infrastructure and vested interests in fossil fuels, making it necessary to develop comprehensive energy transition plans.
    • The energy sector's transition to renewables presents challenges, particularly regarding core economic sectors like vehicle manufacturing.
  • International Cooperation:
    • Collaborating with other nations on issues like emissions standards, cross-border transportation, and harmonizing policies can be difficult due to geopolitical tensions and differing national priorities.
    • Shifts in geopolitics have led to greater economic competition between emerging economies and industrialized countries.
  • Behavioral Change:
    • Encouraging people to adopt more sustainable travel behavior, such as carpooling, public transit, or active transportation, can be challenging due to cultural norms and lifestyle preferences.
    • China, India, and Indonesia have relatively low per capita emissions but face significant increases in absolute transport-related emissions.

However, there are also positive trends when it comes to sustainable transport in G20 countries :

  • Growth in Electric Vehicles (EVs):
    • The market for electric vehicles (EVs) has seen significant growth in recent years. In G20 countries, the EV fleet expanded almost eightfold from 2015 to 2020, reaching 8.4 million vehicles.
    • Electric vehicle new sales in G20 countries reached 1.6 million in 2020.
    • International Energy Agency (IEA) scenarios forecast significant growth in the cumulative EV stock fleet for China, India, the USA, and the EU, ranging from 123 million to 195 million EVs.
  • Charging Infrastructure:
    • As of 2020, G20 countries had 560,000 slow charging points and 330,000 fast charging points in publicly available charging infrastructure, with an average ratio of around 10 electric vehicles per public charging point.
    • Data limitations exist as only 14 countries provide up-to-date information for electric cars, and even fewer offer current data for buses, vans, or two-to-three wheelers.
  • Transition to Clean Energy:
    • G20 countries show a clear trend toward decarbonization, with the average share of renewables in G20 countries being around 28% in 2019 (approximately 25% if weighted with respective total electricity generation in terawatt-hours) and increasing by nearly 5 percentage points.

To maintain operational transport systems while avoiding long-term disadvantages, countries must prioritize investment in clean, renewable, and efficient modes of transport.

    • The government's immediate target is to set up 4,000 MWh of battery storage capacity to increase renewable energy penetration in the national grid.
    • The Central Electricity Authority (CEA) projects that 27,000 MW/108,000 MWh of battery storage capacity (or four hours' worth) will be installed by 2029–30

What are the Major Recommendations for Transport Transformation?

  • Transitioning to Sustainable Mobility:
    • Achieving a successful "transport transformation" requires a "mobility transition" and an "energy transition in transport."
    • The "energy transition in transport" aims to transform technology to meet mobility demands efficiently while generating fewer emissions.

  • Promoting Energy-Efficient Transport:
    • Increasing investments in energy-efficient passenger and freight transport can shift consumer demand toward lower-carbon options.
    • Electric vehicles (EVs) offer better energy efficiency, producing about 20% fewer CO₂ emissions than internal combustion engines.
    • Private companies like Audi and Jaguar, supported by GridCars, are installing public EV charging stations in South Africa.
    • In India, two- and three-wheelers are widely used modes of transport, and the country has set a 2030 electrification target for these modes to reduce carbon emissions.
  • Urgent Need for More Ambitious Action:
    • To achieve the objectives of the Paris Agreement and uphold COP26 commitments, more ambitious efforts are needed in the transport sector.
    • While some countries have made promising policy developments, a marginal decrease (-0.15%) in year-over-year growth in transport-sector emissions was observed in 2019.
    • Overall G20 transport emissions increased by almost 6% between 2015 and 2019.
  • Policy Measures to Reduce Transport Demand:
    • Policies that reduce transport demand are needed, and modern communication technologies, such as video conferencing, play a crucial role.
    • Access to reliable, high-speed communication infrastructure is essential for harnessing technology to lower transport demand.
  • Complementing Efficiency with Weight Reduction:
    • Efforts to increase the energy efficiency of light-duty vehicles should be complemented by measures that encourage the use of smaller, lighter vehicles.
  • Renewable Energy for Electrification:
    • Electricity used in the transport sector should come from renewable sources.
    • Support measures for electrification or power-to-X technologies should be linked to renewable energy requirements.
    • Decarbonization efforts in land-based transport and expansion of power-to-X fuels for aviation and shipping should be based on renewables to be effective.
  • Grid Emission Factors and Energy Transition:
    • Grid emission factors reflect progress in the energy transition of the power sector in G20 countries.
    • While most countries show moderate improvement in grid emission factors, Brazil, Indonesia, Japan, and South Africa have higher GHG emissions per kWh compared to 1990.
  • Power-to-X Fuels for Decarbonization:
    • Long-haul aviation and maritime shipping still depend on energy-dense fuels.
    • G20 member states should lead the market ramp-up of power-to-X by adopting ambitious policies, increasing funding, and fostering cooperation between states.
      • “Power-to-x” refers to a series of techniques and pathways allowing to convert, store and utilize renewable electrical energy.
  • Elimination of Fossil-Fuel Subsidies:
    • Several countries, including India, have begun to reduce fossil-fuel subsidies.
    • Fossil-fuel subsidies distort the market, favoring carbon-intensive transport modes.
    • Eliminating these subsidies would free up resources for public transport, electrification, and zero-carbon fuels.
  • Need for Integrated System Approaches:
    • The transport sector requires integration with other sectors like electrification and digitalization.
    • The G20 should establish a work stream dedicated to transforming transport to identify measures promoting greater integration and guide decarbonization.

Conclusion

Thus, solely emphasizing on vehicle technology, such as fuel standards and electrification, falls short of achieving effective decarbonization. To address this challenge comprehensively, a holistic approach is required that not only promotes efficient, less carbon-intensive modes of transportation but also embraces an integrated system approach.

The integrated system approach should encompass addressing grid emission factors, investing in power-to-X fuels, and eliminating fossil-fuel subsidies, all of which are crucial steps toward advancing the energy transition and achieving decarbonization within the transport sector.
