Nature Climate Change, Published online: 11 March 2026; doi:10.1038/s41558-026-02578-0The adoption and effectiveness of carbon pricing are highly reshaped by interactions with other climate mitigation policies. A global comparative assessment of policy synergies and conflicts can guide policymakers in designing policy portfolios that can achieve higher mitigation cost-effectiveness.

abatify summary
Ecosystem Impact
The effectiveness of carbon pricing in preserving biodiversity and carbon sinks is contingent upon complementary land-use and conservation policies; without these synergies, carbon prices alone may lead to unintended land-use changes that disrupt local ecological balances and sequestration potential.
Systemic Reality
Policy interactions shift the risk-return landscape for global markets, where overlapping regulations can either amplify the signal for green investment or create market inefficiencies that distort carbon credit pricing and complicate the alignment of international financial frameworks with net-zero pathways.
