Sentences with phrase «halocarbon emissions»

Not exact matches

Combustion of coal, oil, and natural gas, and to a lesser extent deforestation, land - cover change, and emissions of halocarbons and other greenhouse gases, are rapidly increasing the atmospheric concentrations of climate - warming gases.

In 1990, emissions of halocarbons and other halogenated compounds occurred almost exclusively in the OECD90 region, which contributed 95 % to the world total (Figure 5 - 19).

Consequently, the most advanced climate models now require, in addition to concentrations or emissions of greenhouse gases (CO2, CH4, N2O and halocarbons), emissions of reactive gases and aerosol precursor compounds (SO2, NOx, VOC, BC, OC and NH3), to model atmospheric chemistry and interactions with the climate system.6 For most variables, a sectoral differentiation would improve the quality of the calculations (e.g. from power plants and agricultural burning).

Complementing these regulations, Canada has published an Environmental Code of Practice outlining best practices to minimize and eliminate emissions of halocarbon refrigerants when operating and servicing refrigeration and air conditioning equipment.

Emissions of the six kinds of air pollutants causing the problem — CO2, methane, black carbon, halocarbons, nitrous oxide, and carbon monoxide, plus VOCs — must all be reduced dramatically.

We validated parameterization of the model diffusivity using CH4 and three halocarbon species (CFC11, CFC113, and CCl4) for which atmospheric histories have been estimated from emission scenarios and real - time measurements (60 — 62).
