The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios).

20 % of stations registered concentrations above the EU ozone (O 3 ) target value for the protection of human health. The percentage of the EU-28 urban population exposed to O 3 levels exceeding the WHO AQG value was 96% in 2017—showing scarcely any fluctuation since 2000.

Further, the agency said, technical progress has been made in developing technologies and approaches that can reduce NO x emissions beyond the standards put in place in the 2000 rule. (In the final HD Phase 2 rule, EPA had noted the evidence supporting the need for more stringent national NO x emissions standards.).

The existing US NO x cap-and-trade program lowered 2008 summertime NO x emissions from power plants and large industrial sources 62% compared to year 2000 levels and 75% lower than in 1990, according to a report released by the US Environmental Protection Agency (EPA).

giga tonne carbon dioxide equivalent (GtCO 2 eq) (2.2%) per year from 2000 to 2010 compared to 0.4 GtCO 2 eq (1.3%) per year from 1970 to 2000. Total anthropogenic GHG emissions were the highest in human history from 2000 to 2010 and reached 49 (±4.5) Estimates of the economic costs of mitigation vary widely.

And hydroxyls drive long chains of reactions involving other common gases, including ozone. That’s noteworthy because nitrogen oxides have primarily been associated with ozone formation and warming in the past. Radiative forcing by greenhouse gases from 1750 to 2000. Similar reactions influence the creation of nitrate aerosols.

per year from 2000-2007. For 30 reference glaciers in nine mountain ranges tracked by the World Glacier Monitoring Service, the mean rate of loss since 2000 has roughly doubled since the rate during the previous two decades. Global emissions were growing by 1.1% each year from 1990-1999 and this accelerated to 3.5%
