Reducing a carbon footprint is the heart of climate action — offsets only come later. The Science Based Targets initiative (SBTi) frames the ambition clearly: halve emissions before 2030 and reach net zero before 2050, in line with the Paris Agreement's 1.5°C goal. For manufacturers, that means cutting emissions across Scope 1, 2 and 3, not just buying credits. This article sets out practical reduction strategies.
Set a Science-Based Target First
A credible reduction program starts with a target. SBTi, a partnership of CDP, the UN Global Compact, WRI and WWF, validates company targets against climate science. The process runs through five steps: commit, develop, submit for validation, announce, and disclose progress. Importantly, SBTi excludes the use of offsets for target achievement — the cuts must be real. A validated target keeps the program disciplined and signals credibility to buyers and investors.
Reduce Scope 1 and Scope 2
These are the emissions a manufacturer controls directly or through purchased energy, so they are the fastest to act on.
Energy efficiency. Upgrade motors, lighting, compressed air and process controls to cut kWh at the source.
Electrification of heat and process. Replace gas-fired boilers and furnaces with electric or heat-pump alternatives where the grid allows.
Renewable electricity. Switch purchased power to renewables through power purchase agreements (PPAs), on-site generation, or certified green tariffs (Scope 2).
Fuel switching. Move from high-carbon fuels to lower-carbon alternatives where electrification is not yet feasible.
Tackle Scope 3 — the Supply Chain
For most manufacturers, Scope 3 is the largest share of the footprint, covering purchased goods and services, upstream and downstream transport, and the use and end-of-life of sold products. Effective levers include:
Supplier engagement. Ask suppliers for primary emissions data and low-carbon options, and favor those with their own SBTi targets.
Low-carbon materials. Substitute virgin, high-impact inputs with recycled or lower-footprint alternatives where quality allows.
Logistics optimization. Consolidate shipments, shift to lower-emission transport modes, and locate stock closer to demand.
Material and Process Efficiency
Every unit of wasted material carries embodied emissions. Improving yield, reducing scrap, designing products for lower impact, and recovering heat or water all lower the footprint per unit produced. These actions often pay back through lower input costs as well as lower emissions.
Address the Residual with Removals
Under ISO 14068-1:2023, the carbon neutrality hierarchy is explicit: reduce first, enhance removals next, and only then offset the residual — and only with removal-based credits, while continuously shrinking the offset share. Removals are the final step, not a substitute for cuts. Our team can help sequence reduction and neutrality work.
Measure, Report, Repeat
Track emissions annually against a base year using the ISO 14064-1:2018 inventory, verify under ISO 14064-3, and disclose through SBTi and CDP. Regular internal tracking surfaces new hotspots early and keeps the reduction curve on track.
FAQ: Carbon Footprint Reduction
Q: What is the most effective way to reduce a manufacturer's carbon footprint?
A: Start with energy efficiency and switching purchased electricity to renewable sources (Scope 2), then electrify process heat and engage suppliers on Scope 3, which is usually the largest share. Set an SBTi target to keep the program disciplined.
Q: Does the SBTi allow the use of offsets?
A: For target achievement, no. SBTi excludes the use of offsets; reductions must come from actual emission cuts across Scope 1, 2 and 3. Offsets are separate from target achievement.
Q: Why is Scope 3 so hard to reduce?
A: Scope 3 covers the value chain — purchased goods, transport, use of products — where the manufacturer does not control the emissions directly. It requires supplier data, engagement and sometimes product redesign, which takes longer than on-site actions.
Q: How does carbon footprint reduction relate to carbon neutrality?
A: Reduction is the first and mandatory step under ISO 14068-1:2023; only the residual is balanced by removal-based credits after reductions and removals. You cannot claim neutrality without first cutting emissions.
Q: How often should progress be measured?
A: Annually against the base year, using the ISO 14064-1 inventory and ISO 14064-3 verification, and disclosed through SBTi and CDP. Frequent internal tracking helps catch hotspots early.
Conclusion
The most credible footprint reduction combines energy efficiency, renewable power, supply-chain engagement and a validated SBTi target, with removals reserved for the residual under ISO 14068-1. Measure yearly and verify under ISO 14064-3. Contact our specialists to build your reduction roadmap.
