have-rio+20-commitments-already-been-broken?

Brazil, China and India have the dubious honor of becoming the first nations to directly contradict the pledges made at the Rio+20 summit last month. All 193 member states of the UN signed the declaration in Rio which included: “We recognize that the phase-out of ozone-depleting substances is resulting in a rapid increase in the use and release of high global-warming … [Read more...]
