The amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide. This is according to the UN’s World Meteorological Organization annual Greenhouse Gas Bulletin.
The amount of CO2 in the atmosphere reached 396.0 parts per million in 2013, the largest annual increase for the period 1984-2013. Atmospheric methane also reached a new high; levels have been steadily increasing since 2007, after a temporary period of levelling off.
The ocean, which absorbs one-fourth of CO2 emissions produced by human activity, has become increasingly acidic; the current rate of ocean acidification is unprecedented at least over the last 300 million years, based on proxy-data from paleo archives.
Public transport sector has the means, and the will, to act on climate
This alarming bulletin has added to the greater urgency for concerted international action against the accelerating and potentially catastrophic effects climate change.
UITP will be present at the UN Climate Summit next week in New York to declare to international governments that public transport has the means, on the ground, of reducing CO2 emissions and ultimately avoiding the fate that awaits the earth if we fail to act.
Public transport is a vital weapon in the fight against climate change. By choosing a low-carbon mobility model and fulfilling our strategy, called PTx2, of doubling the market share of public transport by 2025, we can prevent the emission of 550 million tonnes of carbon dioxide (CO2)equivalent.
