Carbon Pricing Mechanisms: Implementing carbon taxes and cap-and-trade systems to incentivize emissions reduction.

Data Insight: Carbon pricing initiatives cover approximately 23% of global GHG emissions, with prices ranging from $1 to over $100 per tonne of CO2, highlighting the disparity in global adoption.

Grid Modernization: Investing in smart grids to integrate variable renewable energy sources like wind and solar efficiently.

2. Transport Sector

Transport policies focus on reducing emissions from road, rail, aviation, and maritime sectors:

Vehicle Electrification: Subsidies and mandates for electric vehicle (EV) adoption, as seen in Norway, where EVs constitute over 80% of new car sales.

Data Insight: EV sales reached 10.5 million units globally in 2022, representing 14% of new car sales, a significant rise from just 4% in 2020.

Fuel Efficiency Standards: Establishing stringent standards for fuel consumption and emissions for internal combustion engine vehicles.

Data Insight: The International Council on Clean Transportation (ICCT) estimates that improved fuel efficiency standards could save 1.5 billion tonnes of CO2 by 2030.

Public Transit Investments: Expanding public transport networks and promoting active mobility options like cycling and walking.

Data Insight: Investments in public transit in cities like Paris have led to a 30% increase in ridership and a 10% reduction in road congestion over the past decade.

3. Industrial Sector

Industries are responsible for about 21% of global CO2 emissions. Key decarbonization policies include:

Energy Efficiency Programs: Encouraging the adoption of energy-efficient equipment and processes.

Data Insight: According to the International Energy Agency (IEA), industrial energy efficiency improvements could reduce emissions by 8 gigatonnes by 2050.

Circular Economy Initiatives: Promoting waste reduction and recycling to minimize resource consumption.

Hydrogen and Carbon Capture Technologies: Supporting R&D for green hydrogen and carbon capture, utilization, and storage (CCUS).

Data Insight: As of 2023, there are over 30 large-scale CCUS projects worldwide, capable of capturing 44 million tonnes of CO2 annually. However, this represents only 0.1% of global emissions.

India's Decarbonization Policies in Comparison

India, as one of the largest emerging economies, has adopted a range of decarbonization policies, which reflect its unique developmental challenges and opportunities:

1. Energy Sector

Ambitious Renewable Energy Targets: India aims to achieve 500 GW of non-fossil fuel capacity by 2030 and 50% of its electricity from renewables.

Comparison: While India’s targets align with global ambitions, its reliance on coal for over 50% of its energy mix presents a significant challenge compared to countries like Norway, which rely heavily on hydroelectricity.

Solar Energy Leadership: India’s solar energy capacity has grown from 2.6 GW in 2014 to over 70 GW in 2023, driven by initiatives like the International Solar Alliance (ISA).

Comparison: India’s rapid solar deployment surpasses many developed nations in terms of growth rate but faces constraints in grid infrastructure.

2. Transport Sector

FAME (Faster Adoption and Manufacturing of Electric Vehicles): Subsidies and incentives for EV production and adoption aim to electrify 30% of vehicles by 2030.

Comparison: India’s EV adoption lags behind Norway but represents significant progress in a price-sensitive market.
