Greenhouse Gases
Accounting for and mitigating carbon emissions by applying sector-specific expertise at scales from single buildings to entire regions
Regulatory obligations for greenhouse gases (GHG) are changing rapidly and are increasingly stringent. You may be required to estimate the anticipated carbon footprint for new development or report annual emissions for existing structures.

But positive drivers are also present. You may be wondering if you can save money under cap-and-trade policies. Or you may want to strengthen your organization’s public image as environmental leader and good corporate citizen by reporting and managing carbon emissions.
Our service
We provide either of two compliance services:
- Monitoring/measurements, accounting, and reporting of GHG emissions, emission reductions, and offsets; or
- GHG verification to ISO 14065 (ANAB-Accredited Greenhouse Gas Verification Body - Accreditation #1053).
RWDI is an accredited verification body by the ANSI National Accreditation Board and is accredited to ISO/IEC 17029, Conformity assessment – General principles and requirements for validation and verification bodies. RWDI’s verification process is conducted according to ISO 14064-3:2019, ISO 14065:2020 and ISO 17029:2019.
RWDI is accredited to conduct verification services related to GHG emissions and removals at the organizational level for the following sectors:
- Group 1: General
- Group 2: Manufacturing
- Group 3: Power generation
- Group 4: Mining and mineral production
- Group 6: Metals Production
- Group 7: Chemical production
- Group 8: Oil and gas extraction, production and refining, including petrochemicals
- Group 9: Waste
- Group 10: Agriculture, forestry and other land use
RWDI is also accredited to provide verifications of assertions related to GHG emission reductions and removals at the project level for the following scopes:
- Group 1: GHG emission reductions from fuel combustion
- Group 2: GHG emission reductions from industrial processes (non-combustion, chemical reaction, fugitive and other)
- Group 3: Land Use and Forestry
- Group 4: Carbon Capture and Storage
- Group 5: Livestock
- Group 6: Waste Handling and Disposal
RWDI conducts verifications under the following greenhouse gas reporting programs:
- British Columbia Output-Based Pricing System
- Alberta Technology Innovation and Emissions Reduction (TIER) Regulation including Alberta Emissions Offset Registry
- Saskatchewan Output-Based Pricing System
- Ontario Emissions Performance Standards Program
- Canada Federal Output-Based Pricing System
- Canada Standards Association GHG CleanProjects® Registry
In a complementary service, we can identify GHG credit opportunities and develop strategies to reduce emissions.
Our experts in greenhouse gases are knowledgeable about all aspects of understanding, quantifying, verifying, and mitigating “carbon” emissions. Our team has cross-disciplinary expertise in
- Sector-specific needs (industrial, transportation, oil and gas, waste, commercial, and residential sectors)
- Ambient air quality (generation, dispersion, and mitigation of pollutants)
- Broader implications of climate change
- Energy performance (inter-regional, regional, city, infrastructure, masterplan, and building scales).
We provide extremely thorough, clear and usable GHG documentation. Key to our verification service is a formal management system that ensures consistent and reliable verification. And we’re always glad to answer your questions, to make sure you get the best value from our work.
RWDI also offers several related services that can enhance the value of GHG analyses.
We can help develop solutions to reduce your future carbon footprint. In this role, we draw on RWDI’s experience with evaluating industrial activities, developing emission inventories and analyzing strategies for improving air quality through engineering and process solutions.
