FP2030 is a global partnership for family planning. Building on the successes and lessons of FP2020, the family planning community is embarking on a new decade of progress. The FP2030 partnership will preserve and expand on the best of FP2020 but shift the balance of power so that countries are in the lead, decision-making is localized, civil society is a full partner in accountability, and commitments are made and implemented in a culture of transparency. Advocacy and accountability are twin pillars of the FP2030 agenda. Evidence-based advocacy is the engine that drives progress on family planning and makes the partnership’s goals possible; accountability is the backbone that ensures commitments are met. Civil society has a central role to play in both.
