A briefing prepared for the Bonn Climate Change Conference, from 20-25 October 2014. The Montreal Protocol has resulted in a 98 per cent drop in the production and consumption of ozone-depleting substances (ODS) since 1987, an immense achievement now overshadowed by looming climate threats of hydrofluorocarbons (HFCs)
A report for the 34th meeting of the Open-Ended Working Group of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer.
A briefing to the 19th Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) meeting from 11-22 November 2013 in Warsaw, Poland, arguing that swift, effective and large reductions in greenhouse gases must start now
In a year that has seen concentrations of atmospheric carbon dioxide pass the 400ppm mark and the world’s scientific community issue its starkest warning yet that human activities will result in far-reaching disruption of the climate system, the need to swiftly rein in anthropogenic greenhouse gas emissions is acute
China and India are expected to release vast amounts of hydroflourocarbon-23 (HFC-23) into the atmosphere, causing global greenhouse gas emissions to skyrocket. HFC-23, a by-product of HCFC-22 production, used in air-conditioning and refrigeration, is 14,800 times more damaging to the climate than carbon dioxide
A briefing highlighting an opportunity to maximise the climate benefits of the hydrochlorofluorocarbon (HCFC) phase-out
