Climate change scenarios and Technology Transfer Protocols

► Climate policy scenarios are assessed with differentiated commitments in carbon emission control supported by Technology Transfer Protocols. ► Donor countries finance, via carbon-tax revenues, the exports of carbon-free technologies in developing countries helping to get a new international agreement. ► Developing countries experience increased welfare from access to subsidized technology, and profit from the reduction of damages related to climate change and secondary benefits. ► Under Technology Protocols alone and without future commitments by today's developing countries (even under low or zero emissions of Annex B countries) climate damages are unavoidable.
