Carbon accounting is the entry point. A credible sustainability program is the outcome.
Higher Impact helps companies build Scope 1-3 inventories and the supporting systems, methods, supplier workflows, and reporting outputs needed to stand behind the numbers.
Scope 1-3 Carbon Accounting
Build a credible GHG inventory aligned to the GHG Protocol and designed for internal decision-making, customer requests, investor review, and future assurance.
- Organizational and operational boundary review
- Scope 1, Scope 2, and Scope 3 data collection
- Emissions factor selection and documentation
- Data QA and outlier review
- Baseline development and annual refreshes
- GHG Protocol-aligned methodology documentation
Scope 2 Market-Based Validation
For companies using renewable energy, onsite generation, RECs, PPAs, or supplier-specific instruments, Scope 2 market-based accounting needs careful documentation and validation.
- REC claimability review
- Market-based methodology review
- Contractual instrument treatment
- Facility-level documentation
- Emissions factor hierarchy review
- Pre-assurance readiness memo
Scope 3 Methodology & Supplier Data
Scope 3 is where most companies struggle. We help move from rough estimates toward practical, defensible, decision-useful methods.
- Category screening and prioritization
- Spend-based, activity-based, hybrid, and supplier-specific methods
- Supplier data strategy
- EcoVadis and supplier emissions data integration
- Emissions factor strategy
- Data quality tiers and improvement roadmap
- Product carbon footprint readiness
Pre-Assurance Readiness
Before external assurance, companies need clean documentation, clear calculation logic, and a defensible audit trail.
- Methodology memos
- Assumption logs
- Evidence and source documentation
- Data controls and QA workflows
- Internal review packages
- Assurer-ready documentation
Reporting, Ratings & Disclosure
Translate sustainability data into credible reporting for customers, investors, regulators, and rating platforms.
- CDP
- EcoVadis
- TCFD
- ISSB / SASB
- CSRD readiness
- California climate disclosure readiness
- Customer sustainability questionnaires
- Investor reporting packages
Net Zero, SBTi & Reduction Roadmaps
Once the baseline is credible, we help companies identify practical reduction pathways and build a roadmap that leadership can act on.
- SBTi target setting
- Net zero transition planning
- Reduction lever analysis
- Supplier reduction strategy
- Internal business case development
- Implementation roadmap
Data Systems & Automation
Sustainability reporting should not be rebuilt from scratch every year. We help companies design repeatable workflows for data collection, QA, and reporting.
- Data collection workflows
- Utility, facility, procurement, supplier, and HR data inputs
- Platform implementation support
- Data model design
- QA processes
- Reporting calendar and ownership model
Fractional Sustainability Lead
For companies without a dedicated sustainability function, or with teams that are over capacity, Higher Impact can act as an embedded execution partner.
- Sustainability roadmap ownership
- Cross-functional project management
- Executive updates
- Vendor and partner coordination
- Data and reporting governance
- Customer and investor response support
