ENVIRONMENT SUBNOTES

_{N/A is used to identify metrics that were not tracked in the specified year.}

_{Due to rounding, the sum of NextEra Energy emissions may not equal the total emissions of Florida Power & Light, NextEra Energy Resources and Gulf Power.}  

_{¹ Includes direct CO2 emissions data for NextEra Energy owned power plant sites as well as joint ownership sites, which were adjusted to account for the Company's ownership share only. Increases in total NextEra Energy emissions and rates are mainly attributed to the acquisition of Gulf Power and NextEra Energy's acquisition of ownership share in natural gas power plants Oleander & Stanton. Increase in FPL’s CO2 emissions is a result of the addition of Okeechobee Clean Energy Center (state-of-the-art natural gas combined cycle power plant) and the additional 2 million MWhs of generation to serve customer load. The decrease in SO2 emissions for NEER is a result of less generation from the Wyman oil-fired power plant in 2019 compared to 2018.}

_{² NextEra Energy conducts business under regulatory regimes that require CO2 rather than CO2e reporting, therefore this report is being made consistent with those requirements. CO2e includes emissions of other greenhouse gases associated with the production of electricity (N2O and CH4) that are insignificant (<0.01%) compared to the numbers reported.}

_{³ Please note that the environmental attributes of NextEra Energy's electric generating facilities have been or likely will be sold or transferred to third parties, who are solely entitled to the reporting rights and ownership of the environmental attributes, such as renewable energy credits, emissions reductions, offsets, allowances and the avoided emission of greenhouse gases.}

_{⁴ Gulf Power purchased additional electricity powered by wind, solar and natural gas to serve customer load. Power delivered to customers in 2020 had a total of 2,319 tons of NOx; 438 tons of SO2 and 5,983,255 tons of CO2. The resulting delivered electricity emissions rates for Gulf Power customers was 0.40 lbs/MWh of NOx, 0.08 lbs/MWh of SO2 and 1,025 lbs/MWh of CO2.}

_{⁵ Water metrics reported reflect use for plant operations, including the addition of Gulf Power facilities in 2019. Metrics for 2016-2018 differ from previously reported metrics. An improved water management accounting system was implemented in 2017 and further improved in 2018 that included refining water use definitions through external benchmarking and more consistently applying them across our fleet. The Company utilizes the World Resources Institute's (WRI) definition for water consumption. According to WRI, water consumption is the portion of water use that is not returned to the original water source after being withdrawn. n 2020, we revised the water balance for one our facilities by recognizing that a potable groundwater withdrawal had previously been classified as a surface water withdrawal. Additionally, a separate groundwater withdrawal for the facility required recategorization from non-potable groundwater to potable groundwater to be consistent with Florida Administrative Code section 62-520.410 (Classification of Ground Water, Usage, Reclassification). These classifications were updated for all reporting years. Note the updated classifications did not impact the value for percent of consumed water.} 

_{⁶ The hazardous waste totals include recycled Universal Wastes which contribute to 93% or more of the total weight.}

_{⁷ 2017 data was based on FPL only and did not include municipal solid waste. In 2018 data gathering was improved to include available waste manifest information for NextEra Energy’s generation, FPL’s power delivery fleet and includes municipal solid waste for Florida-based corporate offices. For our wind fleet, actual waste volume was collected for one half of the 126 sites to generate a per site waste volume average to extrapolate across the remainder of the fleet. This does not include waste associated with repowering of ten wind sites since that waste was handled by a third party. 2019 data also includes newly-acquired Gulf Power generation. Under non-hazardous waste, a significant portion of the 2019 reused/recycled number includes waste associated with plant demolition activities at Martin Terminal, Port of Palm Beach, and Fort Lauderdale plant. 2020 wind fleet data includes actual waste volumes collected from one-third of our 142 sites to generate a per site waste volume average extrapolated across the remainder of the fleet.}  

_{⁸ Significant spills are defined as spills resulting in a notice of violation (non-monetary sanction), penalty or fine. A notice of violation is a notification that a federal, state or local agency believes the recipient committed one or more regulatory violations and provides instructions to the recipient on how to come into compliance.}

_{⁹ Significant violations are defined as violations resulting in a fine of more than $100,000.}
