How Project Affects Greenhouse Gas (GHG) Emissions:

['Replaces/avoids GHGs (e.g., projects that replace sources of GHGs, such as the burning of fossil fuels for electricity, heat, transport, or other energy uses)', 'Reduces GHGs (e.g., projects that reduce sources of GHGs, such as through efficiency or other changes in consumption)']

Impact on Underrepresented Groups:

By hydrogen-proofing and rehabilitating gas pipelines, Arculus will unlock a transition to a low-carbon and low-pollutant gas fuel mix that disproportionately benefits Low Income/Disadvantaged Communities (LIDAC).
Why is this the case? All forecasts expect wealthier and advantaged communities to be the first to electrify, ridding their kitchens and basements of appliances based on natural gas combustion, which produces VOCs and other pollutants demonstrated to contribute to rates of asthma. As wealthier populations electrify, LIDAC homes are expected to continue operating gas appliances such as stoves and water heaters, continuing to suffer from the health effects of indoor combustion of natural gas.
However, as the most technically feasible and cost-effective pipeline adaptation method, Arculus can help the gas supply chain become hydrogen-compatible, which has multiple benefits that disproportionately affect LIDAC populations:
   1. Accelerate the adoption of hydrogen in the gas supply, reducing the level of harmful VOCs generated by natural gas combustion in homes;
   2. Reduce methane emissions from pipeline infrastructure, which tends to be more heavily concentrated adjacent to LIDAC neighborhoods;
   3. Over the long-term, facilitate the reduction of the supply costs of gaseous fuels, disproportionately reducing the economic burdens of gas demand from population yet to electrify their homes.
