Decline in ocean pH measured at the Aloha station (University of Hawaii) and yearly mean surface seawater pH reported on a global scale (Copernicus Marine Service)

A decline in pH corresponds to an increase in the acidity of ocean water. Data originate from the Aloha station pH time series (adapted from Dore, J.E., et al., 2009, 'Physical and biogeochemical modulation of ocean acidification in the central North Pacific', Proceedings of the National Academy of Sciences of the United States of America 106:12235-12240). Changes here are similar to those that are observed over a shorter time frame in Europe (see here: http://www.climatechange2013.org/images/figures/WGI_AR5_Fig3-18.jpg). In figure, "In situ measurement (Aloha station)" corresponds to data based on in-situ measurements, while "Calculated (Aloha station)" corresponds to calculated data. Global annual average of surface ocean pH from the Copernicus Marine Service, based on a reconstruction method using in situ data and remote sensing data, as well as empirical relationships. Indicator is available at annual resolution, and from the year 1985 onwards. The error on each yearly value varies, and is added to the data file sheet. The estimated yearly uncertainty envelope shown in the figure is defined as the annual mean of pH ± 2 standard deviations, which corresponds to a 95% confidence interval of the mean estimate.

Green bond issuance as a percentage of total bond issuance by all issuers and each type of bond issuer in the EU, 2014-2022

The figure shows the share of green bonds to total bonds issued in the EU and the share of green bonds of total bonds issued in the EU per issuer, such as corporates, governments, supranationals and subnationals.

Population-weighted concentrations (micrograms per cubic meter) of fine particulate matter (PM₂.₅) in the richest and poorest NUTS3 regions in the EU-27, 2007-2020

The figure shows the annual average population weighted concentration of PM₂.₅ in the poorest quintile (upper line) and richest quintile (lower line) of NUTS3 regions in the EU, as measured by Gross Domestic Product (GDP) per capita at purchasing power standard.

Ratio of population-weighted concentrations of PM₂.₅ in EU NUTS3 regions in the most deprived quintile relative to those in the least deprived quintile, 2007-2020

The graph shows the ratio of the annual average population weighted concentration of PM₂.₅ in the poorest quintile divided by that of the richest quintile of NUTS3 regions in the EU, as measured by Gross Domestic Product (GDP) per capita at purchasing power standard, per year.

European city air quality viewer

Policies to reduce air pollution have led to improved air quality in Europe over the last three decades. However, in some European cities air pollution still poses risks to health. You can use the European city air viewer to check how the air quality was in your city over the past two years and to compare it with air quality in other cities across Europe.
