    Forestry, forestry and wildlife: "Unconditional Contribution In the unconditional scenario, GHG emissions would be reduced by 27.56 Mt CO2e (6.73%) below BAU in 2030 in the respective sectors. 26.3 Mt CO2e (95.4%) of this emission reduction will be from the Energy sector while 0.64 (2.3%) and 0.6 (2.2%) Mt CO2e reduction will be from AFOLU (agriculture) and waste sector respectively. There will be no reduction in the IPPU sector. Conditional Contribution In the conditional scenario, GHG emissions would be reduced by 61.9 Mt CO2e (15.12%) below BAU in 2030 in the respective sectors."

    "Key Long-Term Climate Actions Cleaner and greener vehicles on our roads Singapore is working to enhance the overall carbon efficiency of our land transport system through the large-scale adoption of green vehicles. By 2040, we aim to phase out internal combustion engine vehicles and have all vehicles running on cleaner energy. We will introduce policies and initiatives to encourage the adoption of EVs. The public sector itself will take the lead and progressively procure and use cleaner vehicles."
