This plan is based on proposal put forward by the United State Climate Action Partnership (USCAP) http://www.us-cap.org/, a group of 23 large corporations and 5 non-governmental organizations (NGOs).
USCAP's Blueprint for Legislative Action http://www.us-cap.org/blueprint/overview.asp has called on the United States and other leading industrial countries to commit to greenhouse gas (GHG) emission reduction targets of 40 percent by the year 2030 and 80 percent by the year 2050.
USCAP's memorandum on international climate negotiations http://www.us-cap.org/pdf/Climatewire_Article.pdf note the need for ""a flexible
framework recognizing the strong diversity among major economies." It goes on to call for binding absolute economy-wide reduction targets for developed countries while allowing developing countries a range of binding policy commitments taking into account national capacities, circumstances and policy approaches."
Based on these principles, this plan envisions that emission growth in the developing countries will be significantly slower than in the Business as Usual scenario. But 2050 emissions will be 50 percent above 2005 levels for the rapidly developing countries and nearly twice 2005 levels for other developing countries.
USCAP focuses primarily on emission reduction targets, so this plan does not envision significant changes in deforestation or substantial increases in CO2 sequestration throught tree growth.
