Promote public transportation, cycling, and walking through infrastructure investment.
Support remote work and virtual collaboration to reduce commuting.
Implement sustainable logistics practices, including route optimization and modal shifts to rail or water transport.
Encourage adoption of biofuels and hydrogen fuel cells where electrification is not feasible.

Corporate policies incentivizing low-carbon travel and employee participation in sustainable commuting programs are increasingly common.

5. Optimize Supply Chains and Foster Circular Economy Practices

The carbon footprint embedded in supply chains often surpasses direct operational emissions. Companies can reduce emissions by:

Requiring suppliers to disclose and reduce their emissions.
Locating suppliers closer to reduce transportation emissions.
Using sustainable materials and reducing resource consumption.
Implementing product lifecycle assessments to identify impact hotspots.
Engaging in circular economy models: designing for reuse, repair, recycling, and waste reduction.

Collaborative platforms and digital tools enable transparency and efficiency in complex global supply chains.

6. Invest in Carbon Capture, Utilization, and Storage (CCUS)

For industries where emissions are hard to eliminate, such as cement and steel production, carbon capture technology is vital. This involves:

Capturing CO2 emissions directly from industrial processes.
Storing the captured carbon underground or utilizing it in products like concrete or fuels.
Scaling emerging direct air capture technologies that extract CO2 from ambient air.

While still developing, CCUS is recognized as crucial for achieving net-zero targets.

7. Promote Sustainable Agriculture and Land Use Practices

Agriculture contributes significantly to methane and nitrous oxide emissions. Mitigation strategies include:

Shifting to plant-based diets to lower demand for carbon-intensive animal products.
Adopting precision agriculture to optimize fertilizer use and reduce emissions.
Implementing regenerative agriculture techniques that enhance soil carbon sequestration.
Reducing food waste through supply chain improvements and consumer awareness.

Forests and grasslands preservation with reforestation and afforestation also play major roles in absorbing atmospheric CO2.

8. Implement Comprehensive Carbon Accounting and Reporting

Accurate measurement and transparent reporting of emissions enable effective management and demonstrate progress. This involves:

Using standardized protocols and software tools to calculate emissions.
Covering all emission scopes and regularly updating data.
Reporting aligned with global initiatives such as the Science Based Targets initiative (SBTi), Task Force on Climate-related Financial Disclosures (TCFD), and the GHG Protocol.

Reliable carbon accounting forms the basis for strategy adjustments, stakeholder communication, and compliance with regulatory frameworks.

9. Leverage Digitalization and Advanced Analytics

Digital technologies enhance carbon reduction by providing real-time data and optimization capabilities:

Internet of Things (IoT) sensors monitor energy use and emissions continuously.
Artificial intelligence (AI) and machine learning optimize processes, predict maintenance needs, and improve resource allocation.
Blockchain enhances transparency and traceability in carbon credits and supply chains.
Virtual collaboration tools reduce travel-related emissions.

Digital transformation also enables innovation in business models towards sustainability.

10. Encourage Behavioral Change and Foster a Low-Carbon Culture

Technology and policies alone are insufficient without the active involvement of people. Businesses and governments can:

Run awareness campaigns highlighting the importance of carbon reduction.
Incentivize sustainable choices such as energy conservation and sustainable commuting.
Integrate sustainability into corporate values and employee performance metrics.
Engage customers through product labeling, carbon footprints, and sustainable options.

Empowered and informed individuals collectively contribute to substantial emission reductions.

11. Enhance Climate Policy and Regulatory Compliance
