The Paris Agreement's Article 6.4 Supervisory Body approved two household cooking methodologies: one for more efficient wood and charcoal stoves and another for broader shifts to cleaner, lower-emission cooking. Eligible projects may seek UN-backed carbon credits, but reductions must be real, additional, conservatively calculated, monitored and verified. The body also adopted a reversal-risk tool so biomass savings cannot keep counting after underlying reductions are undone. About 2.1 billion people still rely on open fires or inefficient stoves, placing climate, forests and household air quality inside one financeable evidence chain.
