Our service
Our system comes with hundreds of thousands of emissions parameters already pre-integrated. We also deliver to our clients our extensive library of abatement actions, which includes the emissions impact, cost uplift and timing of each action.

During the first phase of work we normally work with a snapshot of a company’s enterprise data. We then combine the various sources of enterprise data and deploy our automated mapping routines to calculate, or validate your own estimates of, emissions. After this, we map these activities and emissions into the various GHG Protocol categories.

We then deploy our databases of abatement actions and levers to generate targets and abatement pathways for each category of emission. The forecasts are fed into regulatory submissions, or into our processes, for validating targets against SBTi pathways. Our flexible data layer can then be built upon and fed into other workflow systems and applications.

Climate change may seem more formidable compared to other challenges companies face, but like any problem, tackling it begins with understanding its dimensions. This means measuring emissions and determining where they come from.

Our industry-leading approach
Most of our clients have already made good progress calculating Scope 1 and 2 emissions – those from a company’s operations and power usage – so our role is usually confined to validating the numbers and supporting with abatement actions, target setting and feeding into SBTi and regulatory reporting.

For Scope 3, we normally play a much more prominent role in helping our clients to calculate the emissions in their complex supply chains and downstream activities

To baseline your Scope 3 emissions according to ISO14064 standards, we have a rigorous process that begins with a pilot designed to minimize work for your internal teams. From there, we build a supplier engagement strategy to improve the accuracy of the data. Key to our approach is the transparency and auditability of both the datasets we use and the way we map them to your inventory. Together we create a baseline that will serve as the foundation for your decarbonisation strategy.

We work with industry experts across Oliver Wyman to deal with the inevitable complexities of large organizations, leveraging our automated toolkits and industry-specific data models.
Automotive. Our automotive emissions models go deep into the automotive supply chain with a strong emphasis on component-level upstream Scope 3 emissions as well as downstream (tailpipe) emissions.

Aviation. Our aviation emissions models include all the major aircraft families and cover upstream and supply-chain emissions, maintenance, and extensive fuel analysis.

Chemicals. Our models calculate emissions from the sourcing, production and transportation of chemicals and associated products. We cover industrial and inorganic chemicals, plastics, materials, synthetics, soap, cleaners, paints and agricultural chemicals.

Financial services. Building on Oliver Wyman's deep expertise in financial services, our models help firms understand and calculate their financed emissions for their portfolio. They also help banks to support their customers to adapt to this changing world.

Food and agriculture. Our food module models emissions from agriculture and land use through to food processing, packaging, and delivery.

Manufacturing. Covering consumer products including white goods and electronics, our models consider the raw materials required, means of production and transportation together with life in service by the consumer.

Media and sport. We model emissions associated with the creation of ads and their placement in the media, as well as evaluating scope 3 for sports clubs and institutions.

Mining and metals. Our materials modules calculate the emissions from the extraction and refinement of materials such as oil, gas, cement, steel, aluminium, and chemicals. These models are also used as inputs into our manufacturing models.

Pharmaceuticals and healthcare. Our pharma models can work from a simple list of drug brand names or a more detailed inventory. Either way, we consider the active and non-active ingredients including packaging and transportation.

Power and utilities. Our power module forecasts the emissions intensity of the national power grids of 167 different countries and can be analyzed at the level of individual power plants.

Textiles and apparel. Our retail models consider the fabrics and packaging materials used by the world's most storied fashion houses and largest high street groups.

Transportation. Broadening our work beyond automotive and aviation, our transportation expertise includes trains, shipping and logistics.

Waste. Our models consider the emissions associated with the various forms of treatment, including incineration, landfill and processes that sequest carbon.
