问答题

The United States is committing more than $50 million over the next five years to this initiative, and we urge other countries to join us. Our partners have already contributed an additional $10 million, and we’re working to raise more every day with the goal of reaching at least $250 million over 10 years. This is a project that brings, across our government, the experts together, and many of them have long experience in working on clean stoves, but never before have we pulled our resources and our expertise behind a single global campaign, as we are doing today. And never before have we had the range of global partners and coordination that the Alliance for Clean Cookstoves brings with it.
