Agnes runs a small-scale biogas plant project in rural Malawi, aimed at reducing methane emissions from agricultural waste. She intends to seek carbon credits under ISO 14064-2:2019. She has successfully quantified the baseline emissions and project emissions, demonstrating a net reduction. However, during the validation process, the validator raises concerns about the additionality of her project. Agnes initially argued that the lack of grid connectivity in the region made her project financially attractive compared to grid electricity. The validator, however, points out that several similar biogas projects have recently been implemented in neighboring districts, some even without carbon financing. Moreover, a new national policy provides subsidies for renewable energy projects in rural areas, including biogas. To robustly demonstrate additionality according to ISO 14064-2:2019, which of the following approaches should Agnes prioritize to address the validator\'s concerns most effectively?
