Carbonzero

What Carbonzero does

Carbonzero is a Toronto-based, privately held Canadian firm founded in 2006 that provides greenhouse gas (GHG) measurement, reduction strategy, and carbon offsetting services to more than one hundred corporate clients across Canada and select international markets. Its core offerings are organized into two pillars: Advisory Services (corporate GHG Inventories covering Scope 1, 2, and 3, GHG Reduction Strategies aligned with the Science Based Targets initiative, Green Event Services, and Custom GHG Measurement) and Carbon Offsets (third-party verified offsets sourced from Canadian and international projects, including forest carbon, landfill gas capture, renewable energy, and clean cookstoves initiatives, plus Renewable Energy Certificates). The company differentiates on methodology rigour — using the GHG Protocol Corporate Standard, ISO 14064-1, and IPCC AR5 global warming potentials — and on its proprietary Carbonzero Registry, which assigns unique serial numbers to retired offsets to prevent double-counting.

The business operates on a sales-led go-to-market motion with two distribution channels: a direct enterprise sales team for consulting engagements and large-volume offset purchases, and a self-service online portal (app.carbonzero.ca) for transactional offset purchases and emissions calculations. Pricing is custom and quote-based for advisory services, while offset revenue is generated per tonne of CO2 equivalent. Carbonzero maintains active accounts on leading voluntary carbon registries (VERRA, Gold Standard, CSA CleanProjects, ACR) and partners with First Nations-led projects such as the Great Bear Forest Carbon Project with Coastal First Nations and the Niagara Escarpment Forest Carbon Project with the Escarpment Biosphere Conservancy. The company is founder/management-led under CEO and President Dan Fraleigh, with no disclosed external institutional investment.

Emerging players

• Pachama: Marketplace and advisory for nature-based carbon credits including forestry and reforestation projects. Comparable in offsetting and forestry project expertise, though tech-driven and US-focused.
• Persefoni: Climate management and accounting platform for enterprises, used for corporate GHG inventories and reduction planning. Overlaps Carbonzero's GHG inventory and strategy services but delivers via SaaS rather than advisory hours.
• Watershed: Enterprise carbon accounting platform providing automated Scope 1-3 measurement and offset purchases. Comparable carbon accounting plus offset integration, but technology-led rather than consulting-led.
• Cloverly: Carbon offset API and platform enabling businesses to calculate and purchase offsets programmatically. Adjacent to Carbonzero's Calculator and offset retail but more developer/API-oriented.
• Greenly: Carbon accounting platform targeting SMBs with automated Scope 1-3 measurement and offset purchasing. Competes with Carbonzero's SME segment via a software model.
