GLOBAL warmingCOOLINGBioenergy with carbon capture and storage (BECCS) is a key negative emission technology for climate mitigation. Some countries have made no commitment to carbon neutrality but are viewed as
Fig. 1: Analysis framework linking principles, indicators, and the allocation procedure to estimate fair global warming contributions. Each principle and the corresponding indicators are marked in different colours: pink stands for the principle of equality, light blue for ability to pay, light green...
Equity is a cornerstone of global climate policy, yet differing perspectives mean that international agreement on how to allocate mitigation efforts remains elusive. A rich literature informs this question, but a gap remains in approaches that appropriately consider non-CO2emissions and their warming co...
To stand a chance of limiting global warming to 1.5℃, we have 8 years to almost halve greenhouse gas emissions: 8 years to make the plans, put in place the policies, carry them out and deliver the cuts. The clock is ticking loudly."Emissions fell by about 5. 4% last year during ...
Countries’ nationally determined contributions to mitigate global warming translate to claims of country specific shares of the remaining carbon budget. The remaining global budget is limited by the aim of staying well below 2 °C, however. Here we show how fairness concerns quantitatively condition ...
“Many of us are still waiting for action on loss and damage that we were promised during COP27,” saysFatima Dentonat the United Nations University Institute for Natural Resources in Africa, based in Ghana. “Until we commit to a framework that demands contributions from developed nations,...
The UN Environment Programme (UNEP) said even with new and updated plans and pledges from countries for cutting greenhouse gas emissions in the next decade, the world faces global warming of 2.7 degrees by 2100. The latest climate plans and pledges brought forward by countries to tackle emissions...
Under the Paris Agreement, every country must update its national climate action plan every five years. These NDC plans outline how nations intend to reduce emissions and adapt to climate impacts to limit global warming to 1.5°C above pre-industrial levels. This year’s submissions should...
It requires countries to submit and regularly update their emissions-reduction targets in the form of nationally determined contributions (NDCs). A process called the Global Stocktake (GST) examines countries’ collective progress toward achieving the Paris Agreement goals of limiting warming to well ...
The optimal pooling method is found to reasonably group countries by selecting those with low bilateral correlations or low risk contributions to the overall pool’s risk. Optimal global pooling is found to increase risk diversification of all regional pools, to lower countries’ shares in the pool...
