"The map fills in because the work is done — not because the pitch deck says so."
The numbers aren't projections.
Every figure below is drawn from completed engagements, filed reports, and audited inventories — not from model outputs or scenario analysis.
Accurate GHG inventories are the load-bearing wall of climate compliance. Before any action plan, before any federal report, before any procurement standard — the math has to be right, defensible, and audit-ready.
Inherited three years of inconsistent scope 3 data from a previous vendor. Mandate rebuilt the entire inventory from source documentation, reconciled against EPA's eGRID factors, and produced a baseline that survived a state audit six months later.
The Inflation Reduction Act and IIJA created the largest federal climate funding window in history — and the most complex application architecture. Most municipalities missed the first round because they lacked the compliance documentation to qualify.
Mandate structured King County's IRA Section 60103 application, cross-walking their existing climate action plan against EPA's Justice40 criteria and DOE's technical eligibility matrix. Application submitted 6 days before deadline.
The average municipal climate action plan has a political half-life of 18 months. Mandate designs plans that embed into procurement codes, capital improvement schedules, and departmental KPIs — so they survive whoever wins the next election.
Mandate's 2022 plan was written into Phoenix's purchasing ordinance and tied to three departmental budget line items. When leadership changed in 2023, the plan continued because defunding it required amending a city ordinance — a 90-day process no department wanted to initiate.
Three mandates.
One integrated practice.
Standalone engagements or a full compliance stack — scoped to your timeline and your reporting calendar.
Carbon Inventories
Scope 1, 2 & 3 · GHG Protocol · EPA GHGRP
We build GHG inventories that satisfy state disclosure requirements, EPA reporting, and third-party verification — simultaneously. The baseline is the foundation. We engineer it to hold.
- Community-wide & government operations inventories
- Scope 3 supply chain quantification
- Audit-ready documentation packages
- Year-over-year tracking frameworks
Climate Action Plans
Policy Architecture · Implementation Roadmaps
Plans designed to outlast the administration that commissioned them. We embed targets into procurement codes, capital schedules, and departmental KPIs.
Procurement Frameworks
Federal Compliance · Vendor Standards
Sustainable procurement policies that qualify agencies for IRA and IIJA funding streams while meeting Buy Clean and EPP requirements.
From the directors who signed the reports.
"Mandate handed us a carbon inventory that our state environmental office accepted without a single revision request. That has never happened in my twelve years doing this work."
"The procurement framework they built is already in our municipal code. When the new administration came in and wanted to roll back our climate commitments, there was nothing to roll back — it was purchasing policy, not a press release."
"The climate plans that survive are the ones written into ordinances, not PowerPoint decks."
