Greenhouse Gas Emissions
Understanding the Goal and Its Data
Complete GHG Emissions by the Energy Sector
Figures 2 & 3: The above pie charts show the contributions of various sources within the energy sector (left) and from various economic sectors that participate in stationary combustion (right). Stationary combustion remains the biggest contributor, with 88% of emissions within this category coming from electric power plants and petroleum refineries.

Power Plant Emissions
Figure 6: The above chart shows self-reported CO2e emissions from 15 large sources in the power sector (power plants) from 2010-2017 in comparison to the 1990 power sector baseline GHG emissions level (line in red).
Note: The 1990 baseline shows emissions from all sources evaluated in the power sector, including large and small emitters. The data from 2010-2017 only shows emission totals from large stationary sources in the power sector emitting 25,000 metric tons of GHG or more per year.

What You Can Do to Reduce Your Carbon Footprint
- Use alternative means of transportation, such as carpooling, biking and riding the bus. Leaving your car at home just two days a week will reduce greenhouse gas emissions by an average of 1,600 pounds per year.
- Under-inflated tires reduce your fuel economy and lead to increased emissions of greenhouse gases and air pollutants.
- Plant trees and vegetation to serve as carbon sinks (which take CO2 out of the atmosphere).
- Reduce electricity usage by turning off lights and appliances and unplugging them when not in use. Even equipment that is off, but still plugged in, draws electricity.
- The Clean Air Branch of the State of Hawaiʻi’s Department of Health has established a Greenhouse Gas Program to combat the threat of climate change and sea level rise. Learn more about the program and Hawaiʻi’s GHG rules here.
- The EPA provides publicly available data to track Hawaiʻi's large stationary source GHG emissions. To check out specific facility information, use its Greenhouse Gases Tool.
