Puerto Rico’s 2019 and 2021 Greenhouse Gas Inventories Report

July 2023

On behalf of the Puerto Rico Department of Natural and Environmental Resources (DNER), AEC staff and partners prepared a report that presents the results for Puerto Rico’s 2019 and 2021 greenhouse gas emission inventories together with 20-year emissions projections under several scenarios and sensitivities. AEC established a methodology for conducting greenhouse gas emission inventories in Puerto Rico, which went through a comprehensive quality assurance and quality control process by an Expert Panel (established for this project and composed of experts in greenhouse gas emissions measurement and Puerto Rico climate and energy issues). Using AEC’s Emissions Measurement Inventory Tool (AEC-EMIT), AEC calculates net greenhouse gas emissions released in Puerto Rico’s seven emitting sectors: (1) Power Supply, (2) Direct Fuel, (3) Industrial Processes and Product Use, (4) Transportation, (5) Agriculture, (6) Forestry and Other Land Use, and (7) Waste Management.

Puerto Rico’s 2019 Climate Change Mitigation, Adaption, and Resiliency Law (i.e., Puerto Rico Act No. 33-2019) measures mandated emission reductions against an estimated 2005 emissions level of 53.3 MMT CO₂e and calls for a 50 percent reduction relative to 2005 emissions by 2025 (26.7 MMT CO₂e). Emission levels achieved in 2021 (34.3 MMT CO₂e) represent a 36 percent reduction in emissions from 2005 levels. With 14 percentage points and 4 years left to go, Puerto Rico must find another 7.7 MMT CO₂e to eliminate. Based on the Business-as-Usual projection in AEC’s analysis, Puerto Rico’s greenhouse gas emission levels will reach their mandated levels (50 percent of 2005 levels, or 26.7 MMT CO₂e) in 2035, 10 years later than the required 2025 target.

Based on the analysis presented in this report, AEC has identified several key recommendations to further facilitate Puerto Rico’s work towards achieving its ambitious and necessary decarbonization goals set out in Puerto Rico’s 2019 Climate Change Mitigation, Adaption, and Resiliency Law, including: (1) better data collection, (2) increased climate progress reporting (3) reprioritization in rebuilding its electric sector, and (4) a new focus in transportation planning.

Comparing Connecticut's Electric Vehicle Charging Program with Others from around the United States

Prepared on behalf of Connecticut Office of Consumer Counsel

Authors: Bryndis Woods, PhD, Sachin Peddada, Jay Bonner, Liz Stanton, PhD

March 2023

On behalf of the Connecticut Office of Consumer Counsel, this Applied Economics Clinic (AEC) white paper reviews the potential for electric vehicle (EV) charging programs to provide net benefits to consumers in Connecticut and fourteen other states. AEC finds that Connecticut’s EV charging programs are well-positioned to provide net benefits to consumers and meet the state’s EV and electric vehicle supply equipment deployment goals. Connecticut stands out as a leader due to the detailed nature of its EV and EV charging deployment goals, the inclusion of alternative rate structures to incentivize public EV charging stations, the availability of incentives to cover up to 100 percent of EV charging “make-ready” costs, and enhanced incentives for underserved communities (inclusive of low-income populations). AEC also finds, however, that Connecticut’s EV charging program could be strengthened by adopting best practices from other states’ programs, such as by setting more ambitious EV and EV charging deployment goals, working to target EV charging in as equitable a fashion as possible, and by offering ongoing incentives for EV charging.
