Greenhouse Gas Inventories

Greenhouse Gas Inventory

DOEE regularly tracks the District’s greenhouse gas emissions in order to measure our progress towards reducing emissions 50% by 2032 and 100% by 2050. Greenhouse gas inventories identify the major sources of greenhouse gasses and measure how much they pollute. Major sources include energy used by homes and buildings, transportation, and solid waste. We track emissions across the District using the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC), as well as from our own government operations, using the Local Government Operations Protocol (LGO Protocol).

The first District greenhouse gas inventory was completed for 2006. DOEE releases an annual inventory with data available for 2009-2016.

Progress towards Emissions Reduction Goals

The District is on track to meet its ambitious goals to halve emissions by 2032, and to become carbon neutral by 2050. In 2016, the District saw a 28% decrease in citywide emissions compared to the 2006 baseline inventory, as well as a 24% reduction in emissions associated with District Government operations. As of this most recent inventory, DC has met 56% of its 2032 emissions reduction goal, demonstrating strong progress towards our 2050 carbon neutrality goal. However, we still have a long way to go. The District’s Clean Energy DC plan, finalized in 2018, calls for ongoing local action to cut energy use in buildings, shift to clean energy sources, and shift the way we move residents, employees, and goods in and around the city, all of which will be critical to meeting these long-term goals. The District’s annual inventory will continue to record progress as the city begins implementing Clean Energy DC.

Emissions Sources in the District

The District’s greenhouse gas inventory tracks emissions by both source and sector: sources refer to the fuels that produce energy, and sectors are the main energy-consuming areas of the economy. In the District, emissions come from three main sectors: buildings, transportation, and waste. In 2016, buildings continued to be the main driver of citywide emissions (75%) followed by transportation (21%) and waste (4%). Within these sectors, the main sources of emissions are electricity (57%), gasoline (19%) and natural gas (17%).
