Regional Greenhouse Gas Inventory (2005-2015)
Through the establishment of the Southeast Florida Regional Climate Change Compact, Broward, Miami Dade, Monroe, and Palm Beach counties committed to collaborate on strategies to reduce the region’s emissions, including the development of an emissions baseline for Southeast Florida. A regional greenhouse gas emissions (GHG) inventory is integral to developing informed climate change mitigation strategies and monitoring the region’s progress over time.
The Compact’s regional greenhouse gas inventory provides a summary of overall emissions trends from across the four counties. The inventory was conducted as a retrospective of 10 years of community-wide emissions, from 2005 to 2015. The inventory scope was limited to systems at the regional scale, including transportation (on-road transportation, passenger rail, freight rail) and stationary energy from residential, commercial, and industrial buildings. The inventory does not include emissions from wastewater or solid waste. All emissions are either produced from sources located within the regional boundary (Scope 1) or as a result of grid-supplied electricity, heat, or steam consumed within the region (Scope 2).
GHG EMISSIONS BY SECTOR
Within this scope, the regional inventory shows that, on average, transportation accounts for 48% of emissions. The built environment accounts for over half of regional emissions (52%), with 26% of emissions resulting from residential energy consumption and 24% from commercial energy consumption. Industrial energy accounts for a small proportion of regional emissions (1%). Within the transportation sector, on-road transportation (vehicle miles traveled) accounts for the vast majority of emissions.
EMISSIONS BY SECTOR
Overall emissions in these sectors (transportation and stationary energy) decreased between 2005 and 2015 by approximately 10%. While the region’s population has grown 10% over this 10 year period, per capita emissions decreased by 18%, from 9.69 metric tons CO2e per person in 2005 to 7.92 metric tons CO2e per person in 2015. Most of the decrease in overall emissions (84% of reductions) resulted from decreased emissions in stationary energy (residential, commercial, and industrial sectors).
2005-2015 Average (by Sector)
Overall emissions in these sectors (transportation and stationary energy) decreased between 2005 and 2015 by approximately 10%. While the region’s population has grown 10% over this 10 year period, per capita emissions decreased by 18%, from 9.69 metric tons CO2e per person in 2005 to 7.92 metric tons CO2e per person in 2015. Most of the decrease in overall emissions (84% of reductions) resulted from decreased emissions in stationary energy (residential, commercial, and industrial sectors).
REGIONAL PER CAPITA EMISSIONS
Carbon intensity is a measure of how much carbon is emitted for every dollar of gross domestic product produced. Southeast Florida has reduced the GHG emissions required to produce a unit of economic output over this decade. In 2005, $1 million in gross regional product generated 233.7 tons of carbon. In 2015, the same economic output generated 167.5 tons of carbon. This represents a 28.3% decline in emission intensity over 10 years represented by this inventory.
The regional inventory covers a different scope than county and city level inventories, therefore this emissions data may differ from other inventories published in the region. For more detailed accounting of emissions associated with individual counties and cities, please refer to county and city inventory reports.
