SAN ANTONIO – (April 8, 2021) – Today, the Office of Sustainability reported the results of the City of San Antonio’s 2019 Greenhouse Gas Inventory. As outlined in the SA Climate Ready Climate Action & Adaptation Plan, an inventory is to be completed every two years. The inventory quantifies greenhouse gas emissions generated by the San Antonio community within the municipal boundary and includes emissions from energy usage and supply, water and wastewater operations, transportation, and waste. The City also calculates emissions generated from municipal operations and follows the methodology outlined in the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC).
From the baseline calculated in 2016, total community greenhouse gas emissions decreased by 0.2%, although population, building energy consumed, and transportation-related emissions increased. Total emissions remained relatively steady due to a reduction in CPS Energy’s emissions factor, a factor that converts activity data into emissions data, and carbon intensity of electricity generation, as well as an updated methodology used to calculate landfill and waste emissions. CPS Energy’s emissions factor has been reduced due to a higher mix of renewable energy in their portfolio in addition to the closure of Deely Coal Power Plant Unit in 2018. (An emissions factor is a factor that converts activity data into greenhouse gas emissions data.) On a per capita basis between 2016 and 2019 emissions decreased by 4%, while population increased 4%. This is different from the overall emissions figure as it considers the total population in San Antonio.
On average, total community emissions need to decrease by a net of 4-5% year on year to meet San Antonio’s goal of carbon neutrality by 2050; however, the reduction may not be linear. The SA Climate Ready Climate Action and Adaptation Plan was adopted by City Council on October 17, 2019.
Key findings for the municipal inventory show a decrease of 41%, driven mainly by a methodology change regarding closed landfills that do not report to the EPA, in line with best practice, as well as a decrease in the carbon intensity of CPS Energy’s electricity generation.
The Office of Sustainability has also released the 2019 Municipal Building Energy Benchmarking Report. This report sets an example of transparency and reporting of energy usage in over 300 municipal buildings since 2011. In addition, the Office of Sustainability has summarized key programs, projects and policies related to local climate action in the SA Climate Ready 2020 Annual Report. The Office of Sustainability prioritizes initiatives that advance climate action and adaptation policy, energy efficiency, municipal sustainability, ‘clean and green’ transportation, and education and empowerment.
