How HVO Reduces Scope 1 Carbon Emissions for Singapore Businesses
Singapore businesses are under growing pressure to measure, report, and reduce their greenhouse gas emissions. For companies operating diesel-powered equipment, vehicles, generators, or vessels, the fastest and lowest-friction path to Scope 1 reduction is switching to HVO (Hydrotreated Vegetable Oil) renewable diesel. No new equipment. No capital expenditure. Same fuel system. Up to 90% lower carbon.
What Are Scope 1 Emissions?
Under the GHG Protocol — the global standard for corporate carbon accounting — emissions are categorised into three scopes:
- Scope 1: Direct emissions from sources owned or controlled by your organisation — e.g., fuel burned in your vehicles, generators, boilers, or vessels
- Scope 2: Indirect emissions from purchased electricity, heat, or steam
- Scope 3: All other indirect emissions in your value chain
Diesel combustion in company-owned equipment is a Scope 1 emission. For logistics operators, construction companies, industrial manufacturers, and marine operators, diesel is often the single largest Scope 1 source.
Singapore’s GHG Reporting Requirements
Several frameworks are converging to require Singapore businesses to disclose and reduce their Scope 1 emissions:
- Singapore Carbon Tax: S$25/tonne CO₂e from 2024, rising to S$45 by 2026 and S$50–80 by 2030. Industrial facilities emitting above 2,000 tonnes CO₂e/year are liable.
- SGX ESG Reporting: SGX-listed companies must report climate-related disclosures aligned with TCFD, including Scope 1 and Scope 2 data, from FY2023.
- MAS Climate Disclosure: Financial institutions regulated by MAS must disclose climate risks and transition plans.
- Singapore Green Plan 2030: National targets include reducing emissions intensity by 36% vs 2005 levels by 2030.
How HVO Reduces Scope 1 Emissions
When you burn fossil diesel, the CO₂ released was sequestered millions of years ago — it is a net addition to the atmosphere. When you burn HVO, the CO₂ released was absorbed from the atmosphere by the plants that produced the feedstock (waste cooking oil, animal fats, crop residues). On a lifecycle basis, the net CO₂ addition is up to 90% lower.
Under the GHG Protocol, you may report the lifecycle emission factor of certified HVO rather than the combustion emission factor. This means your Scope 1 inventory reflects the full lifecycle carbon benefit — not just the tailpipe emissions.
Practical example: A Singapore logistics company running 20 trucks on 500,000 litres of diesel per year generates approximately 1,325 tonnes CO₂e in Scope 1 emissions. Switching to HVO100 reduces this to approximately 130–200 tonnes CO₂e — a saving of over 1,100 tonnes CO₂e annually, with full ISCC certification documentation.
ISCC and RSB Certification Explained
To claim the Scope 1 reduction benefit of HVO, the fuel must carry a recognised sustainability certification:
- ISCC (International Sustainability and Carbon Certification): The most widely recognised scheme for renewable fuels. ISCC certification verifies feedstock origin, chain of custody, and lifecycle GHG values for each batch.
- RSB (Roundtable on Sustainable Biomaterials): An alternative certification scheme with strong environmental and social criteria.
RenewableDiesel.com.sg supplies HVO with batch-specific ISCC or RSB certificates. Each delivery includes documentation showing the feedstock, lifecycle CO₂e value, and certification reference — everything you need for your GHG inventory and sustainability report.
Practical Steps for Singapore Businesses
- Identify your diesel consumption — fleet, generators, marine, or industrial equipment
- Calculate current Scope 1 footprint — litres of diesel × 2.65 kg CO₂e/litre (approximate)
- Request HVO pricing — compare with current diesel cost and factor in carbon tax savings
- Transition fleet or equipment — HVO is drop-in, so transition is as simple as switching fuel supplier
- Update GHG inventory — use the lifecycle emission factor from your HVO sustainability certificate
Calculating Your Emission Reduction
Use this simplified formula for your Scope 1 estimate:
Scope 1 reduction (tonnes CO₂e) = Annual diesel volume (litres) × 0.8445 kg/litre density × (fossil diesel lifecycle factor − HVO lifecycle factor) / 1,000
