Con Edison's Greenhouse Gas Emissions Projections for Rate Years 2022-2025

The New York State Department of Public Service has issued a document detailing Con Edison's response to interrogatories from the Sane Energy Project. In response to question 18, Con Edison provides detailed projections of its total greenhouse gas (GHG) emissions for the rate years 2022-2025. The company's response highlights the importance of understanding the scope of its emissions and the various sources contributing to them.

Key Takeaways:

• Con Edison does not estimate emissions that are upstream of its gas systems, specifically, upstream of the gate stations.
• The company's estimated CO2 emissions from the combustion of natural gas, as presented in its CLCPA Panel's Testimony, have been updated based on more recent data.
• The updated estimate shows the company's current estimate of CO2 emissions based on its Firm Gas Sales Forecast for 2022 to 2025.
• The emissions projections are broken down into two categories: (a) upstream emissions and (b) emissions from combustion, encompassing all gas delivered during the rate years, including gas delivered by infrastructure not currently seeking investment.
• Con Edison's projections aim to provide a comprehensive understanding of the company's GHG emissions footprint.

Statistics:

• Con Edison does not estimate upstream emissions of GHGs.
• The company's estimated CO2 emissions from natural gas combustion for 2022-2025 amount to XXX ton CO2 per year (exact figure not provided in the source).
• The updated estimate in EXHIBIT__(CLCPA-1) reflects a change in the company's emissions projections based on more recent data.
• The projections cover a period of four years (2022-2025) and encompass all gas delivered during this timeframe.
