In summary, carbon accounting is the measurement of a company’s Greenhouse Gas (GHG) emissions - that is, the greenhouse gases that are emitted by the company from its activities and operations. We do this in line with the GHG Protocol.

For companies quantifying their emissions for the first time, you’ll be performing a ‘baseline emissions assessment’. This involves identifying and quantifying all of the sources of emissions within your operation, including direct emissions from activities like burning fossil fuels (driving a car), as well as indirect emissions associated with the consumption of electricity, freight of materials, or from the purchase of goods and services you buy.

Sumday is proud of its education first approach.
