All GWPs depend on the AGWP for CO2 (the denominator in the definition of the GWP). The AGWP of CO2 again depends on the radiative efficiency for a small perturbation of CO2 from the current level of about 380 ppm.
The species in Table 2.14 are those for which either significant concentrations or large trends in concentrations have been observed or a clear potential for future emissions has been identified. The uncertainties of these direct GWPs are taken to be ±35% for the 5 to 95% (90%) confidence range.

Awad stressed that the government places significant importance on developing an integrated waste management system in the Red Sea Governorate, given its strategic importance as one of Egypt’s leading tourism destinations. She emphasized the need to comply with environmental and technical standards governing sanitary landfills, waste treatment facilities and environmentally sound disposal practices. During the meeting, officials reviewed the current status of waste management operations in Hurghada, including collection, transportation, sorting, recycling and final disposal activities. Discussions also covered the infrastructure upgrades required to improve system efficiency and ensure the proper operation of sanitary landfill facilities. Yasser Abdullah, head of Egypt’s Waste Management Regulatory Authority, presented updates on temporary waste collection and sorting sites and outlined measures to strengthen operational management and oversight. He highlighted the importance of improving monitoring mechanisms for waste handling activities and maximizing the recovery of recyclable materials while reducing informal and unregulated practices.
