The meeting, convened at Stanford University and Google's Silicon Valley campus, paired staffers from government agencies and NGOs in the four tropical countries with technical experts from the Amazon Environmental Research Institute (IPAM), the Carnegie Institution for Science, the Forum on Readiness for REDD, Woods Hole Research Center, and Google Earth Outreach. The participants received training to augment existing deforestation, forest degradation and biomass monitoring capabilities, which are highly variable both between countries and within sub-national agencies and jurisdictions.

Deforestation accounts for 10 percent of global carbon emissions, argues new study
(06/21/2012) Tropical deforestation accounted for 10 percent of global carbon dioxide emissions between 2000-2005 — a substantially smaller proportion than previously estimated — argues a new study published in Science. The paper estimates gross carbon emissions from deforestation at 810 million metric tons (with a 90 percent confidence interval of 0.57-1.22 billion tons) per year from 2000-2005, significantly below earlier calculations. Brazil and Indonesia accounted for 55 percent of gross emissions from tropical deforestation during the study period, while dry forests accounted for 40 percent of tropical forest loss but amounted to only 17 percent of emissions.

Palm oil giant making good on forest commitment in Indonesia, finds independent analysis
(05/29/2012) Palm oil giant PT SMART appears to be honoring its commitment to avoid conversion of high carbon forests in Indonesian Borneo, reports a new assessment published by Greenomics, an Indonesian environmental activist group. The report was issued 15 months after PT SMART — a subsidiary of Singapore-based Golden Agri Resources (GAR) and owned by Indonesia's Sinarmas Group — signed a landmark agreement with The Forest Trust (TFT) to spare forests and peatlands that have more than 35 tons of carbon per hectare. The deal came after a damaging Greenpeace campaign, which targeted PT SMART for clearing orangutan habitat in Kalimantan and cost the company millions of dollars in contracts.
Indonesia revises moratorium map; makes contested orangutan forest off-limits
(05/22/2012) Indonesia is making 'encouraging' progress on its push to reduce deforestation by improving governance over its forests and peatlands, but still needs to do more to enforce environmental laws, said the head of the country's Reducing Emissions from Deforestation and Degradation (REDD+) task force speaking at a press conference Monday in Jakarta. Kuntoro Mangkusubroto, Head of the Indonesian President’s Delivery Unit for Development Monitoring and Oversight (UKP4) and Chair of the REDD+ Task Force, said an effort to develop a map of Indonesia's forests and forest concessions has been completed, although the Ministry of Forestry has yet to deliver the map to President Susilo Bambang Yudhoyono, missing last Friday's deadline. The map serves as the basis for a two-year moratorium on new forestry concessions in primary forests and peatlands had been completed.
