Deep Decarbonization Pathways Project (DDPP) Presents Interim Report to UN Secretary-General Ban Ki-Moon
STUDY CHARTS PATH TO LOW CARBON IN MAJOR EMITTING COUNTRIES First Global Cooperative Effort Aims to Support UN Climate Talks "A report for the United Nations released today shows how the major emitting countries can cut their carbon emissions by mid-century in order to prevent dangerous climate change. The report, produced cooperatively by leading research institutes in 15 countries, is the first global cooperative program to identify practical pathways to a low-carbon economy by 2050. The Deep Decarbonization Pathways Project (DDPP) interim report will be presented in a briefing today to UN Secretary-General Ban Ki-Moon, and tomorrow/the day after to the French government, as host of the 2015 United Nations Framework Convention on Climate Change (UNFCCC) climate conference. The interim report supports the UN Climate Summit on September 23, 2014. The full DDPP report will be presented in the spring of 2015."

GR - Refreshing. If only it were practiced. Speaking of which, here's the extent of their negative emissions statement in the full report: "Many low-carbon scenarios, including some in IPCC AR5, project an “overshooting” of the carbon budget in the first half of the 21st century, which must then be offset through net negative emissions in the second half of the century. The popular placeholder for net negative emissions is the integration of biomass energy (BE) with CCS, both as technologies for electricity generation and biofuel production. BECCS combines the dual challenge of large-scale biomass production and large-scale storage of CO2. The feasibility of each component of BECCS is uncertain, and their combination is therefore even less certain at this stage. An alternative approach for net negative emissions would be the direct air capture of CO2 followed by geological storage. Air capture refers to technologies that extract CO2 from the atmosphere at the ambient concentration of CO2 (i.e. 400 ppm). The advantage of direct air capture is that it can be done anywhere without the need for transport of the CO2 to a storage site. A disadvantage is that the process of isolating and removing the CO2 from air at low ambient concentrations is technically challenging, currently expensive, and unproven at scale." GR - Translation: "We're not going to pick winners, but we're going to make the CDR list so small and unlikely that we can ignore it. Meantime, we've picked that winning approach - CO2 emissions reduction - to save the planet." -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
