A state wanting to free ride with regard to ozone depletion would:
sign an agreement to reduce greenhouse gases but continue to produce such ozone-depleting emissions, while other states decrease their own emissions. sign an agreement to reduce greenhouse gases but reduce emissions only if all other signatories also reduce their emissions. refuse to sign an agreement to reduce greenhouse gases because it would not trust other states to reduce their own emissionin freely reduce emissions without signing any entangling agreements.
