Research, analysis and innovative thought on options discussed at the international climate negotiations, including detailed modalities of the ambition-raising mechanism under the 2015 Paris Agreement towards the 2/1.5 °C limit.
If the emissions gap is to be closed and the global warming kept below 2/1.5 °C, as the 2015 Paris Agreement aims, raising the ambition on action against climate change is urgent. The next 10 years will show if a transition towards a sustainable, greenhouse gas-free society can be made.The Paris Agreement puts into place some essential elements to ratchet up national ambition towards the 2/1.5 °C limit and net zero emissions in the second half of this century. However, there is much further work to be done on the exact modalities to effectively raise mitigation ambition. We support the successful implementation of the Paris Agreement through research and analysis, in particular modalities of review and the global stocktake, the nature and level of commitment in Nationally Determined Contributions (NDCs), and the possible shape of a long term goal of net zero greenhouse gas emissions at national level.

Global climate action from cities, regions and businesses Aug 2018 - This report is the most comprehensive assessment of non-state actor commitments to reduce greenhouse gases to date. Key results show that action by cities, states, regions and business can go a long way towards meeting the goals of the Paris Climate Agreement, but their actions alone are not enough to hold global temperature increase to well-below 2°C and work towards limiting it to 1.5° C.
