What does the term "equity approach" refer to in consolidating emissions inventory?

The term "equity approach" in the context of consolidating emissions inventory refers specifically to the practice of assessing emissions based on ownership. This approach recognizes that the responsibility for greenhouse gas emissions can differ based on the ownership structure of assets and operations. By focusing on ownership, this method allocates emissions to the entities that have financial control or equity stake in the operations that generate those emissions.

The equity approach supports a clearer understanding of accountability and impacts, allowing stakeholders to evaluate environmental responsibilities accurately. This is particularly important in corporate environmental reporting, where understanding who is responsible for what emissions can influence corporate policy and sustainability efforts.

In contrast, tracking emissions based on financial contributions or consolidating emissions equally among groups would fail to provide detailed insights into who is truly responsible for emissions related to specific activities. Similarly, focusing only on corporate accountability neglects the broader implications of emissions sources and ownership, potentially obscuring accountability across different entities involved. Thus, the equity approach enhances clarity and fairness in emissions reporting by aligning it with ownership and control.
