Scope 1 Emissions

Scope 1 emissions are the direct greenhouse gas emissions released from sources an organisation owns or controls — fuel burned in its own boilers, furnaces and vehicles, together with process and fugitive emissions released at its own sites.

Carbon Accounting

Scope 2 emissions are the indirect greenhouse gas emissions from the electricity, steam, heating and cooling an organisation purchases and consumes — physically released at the point of generation rather than at the organisation's own sites.

Carbon Accounting

Scope 3 Category 15 covers greenhouse gas emissions associated with an organisation's investments, and is the category that dominates the inventory of banks, insurers and asset managers.

Carbon Accounting

Scope 3 Emissions

Scope 3 emissions are the indirect greenhouse gas emissions that occur across an organization's entire value chain — both upstream in the supply chain and downstream through product use and end of life — and typically represent the largest share of a company's total carbon footprint, often exceeding 70% for manufacturing, retail, and financial sector organizations.

Climate Strategy

A Second Party Opinion is an independent assessment of whether a green, social, sustainability or sustainability-linked financing framework aligns with recognised market principles, published before the instrument comes to market.
