Greenhouse Gas Emissions
Definition
Gases (primarily carbon dioxide, methane, and nitrous oxide) released by human activities that trap heat in the atmosphere and cause climate change. Major sources include burning fossil fuels for transportation, electricity, and heating; industrial processes; agriculture; and waste decomposition. Cities produce approximately 70% of global greenhouse gas emissions but can reduce emissions through clean energy, efficient buildings, and sustainable transportation.
Louisville Context
Louisville emits approximately 13 million metric tons of CO2 equivalent annually. Transportation accounts for 36%, electricity 31%, and buildings 21%. Per capita emissions are higher than national average due to Kentucky’s coal-heavy electricity grid and Louisville’s sprawling development pattern. LG&E’s coal-fired power plants are the region’s largest single emission source.
Why It Matters
Louisville’s greenhouse gas emissions contribute to global climate change that already affects our community through increased flooding, extreme heat, and severe weather. Reducing emissions saves money through energy efficiency, improves air quality and health, and creates clean energy jobs while addressing the climate crisis.
Dave’s Proposal
Dave will reduce Metro Government’s emissions 50% by 2030 through building efficiency retrofits, renewable energy procurement, and fleet electrification—all funded within the $1.025 billion budget. He’ll advocate for LG&E to accelerate coal plant retirements and renewable energy development, and expand TARC service to reduce transportation emissions.
