Study Notes
Climate Change in Singapore
- Challenges in addressing climate change highlighted, particularly pertaining to greenhouse gas (GHG) emissions.
- Encouragement to follow research from the Centre for Climate Research Singapore for insights.
Greenhouse Gases and Global Warming
- Methane, nitrogen dioxide (NO2), and fluorinated gases have significantly higher global warming potentials than carbon dioxide (CO2).
- Emission equivalency:
- 1 tonne of methane = ~30 tonnes of CO2e
- 1 tonne of NO2 = ~300 tonnes of CO2e
- 1 tonne of SF6 = ~23,500 tonnes of CO2e
Major Sources of Greenhouse Gases (GHG)
- Different types of GHGs include CO2, methane (CH4), nitrous oxide (N2O), and fluorinated gases (HFCs, PFCs, NF3, SF6).
Policies Promoting Electric Vehicles in Norway
- Norway implemented policies to incentivize electric vehicle (EV) adoption, such as:
- Zero registration tax
- Free tolls and parking
- Waiving value-added tax
- Public funding of approximately $3.8 billion USD contributed to these incentives.
- Results in 2023:
- 82% of new car sales were EVs in Norway.
- Contrast with U.S. at 7.6% and Singapore at 18.1%.
Science Based Targets Initiative (SBTi)
- SBTi addresses sector-specific considerations for industries including:
- Financial institutions
- Forest, Land and Agriculture (FLAG)
- High-impact industries (iron and steel, cement, aluminum, pulp and paper)
- Information and Communication, Power sectors.
- These sectors are critical for achieving global warming targets through focused engagement.
Case Study: Grab vs. ComfortDelGro
- Total GHG emissions reported:
- Grab: 3.35 million tonnes CO2e
- ComfortDelGro: 1.4 million tonnes CO2e
- Analysis on Scope 3 emissions shows significant disparity, highlighting differences in operational emissions profiles and calculation methodologies.
Understanding Scope Emissions
- Scope 1, Scope 2, and Scope 3 emissions encompass direct and indirect emissions from industrial activities.
- Scope 3 emissions are particularly challenging to measure as they require consideration of the entire value chain.
Regulatory Framework for GHG
- The Montreal Protocol, adopted in 1987, is a universally ratified treaty aimed at regulating man-made ozone-depleting substances.
- The Kyoto Protocol, adopted in 1997 and effective from 2005, established emission reduction commitments for industrialized countries and created flexible market mechanisms for trading emissions permits.
