New Delhi, Oct 27 As intensifying climate impacts across the globe hammer home the message that greenhouse gas emissions must fall rapidly, a new UN Environment Programme (UNEP) report finds that the international community is still falling far short of the Paris goals, with no credible pathway to 1.5 degrees Celsius in place.However, the Emissions Gap Report 2022: The Closing Window Climate crisis calls for rapid transformation of societies finds that urgent sector and system-wide transformations in the electricity supply, industry, transport and buildings sectors, and the food and financial systems would help to avoid climate disaster."This report tells us in cold scientific terms what nature has been telling us, all year, through deadly floods, storms and raging fires: we have to stop filling our atmosphere with greenhouse gases, and stop doing it fast," said Inger Andersen, Executive Director of UNEP."We had our chance to make incremental changes, but that time is over. Only a root-and-branch transformation of our economies and societies can save us from accelerating climate disaster."The report finds that, despite a decision by all countries at the 2021 climate summit in Glasgow, UK (COP26) to strengthen Nationally Determined Contributions (NDCs) and some updates from nations, progress has been woefully inadequate.NDCs submitted this year take only 0.5 gigatonnes of CO2 equivalent, less than one per cent, off projected global emissions in 2030.This lack of progress leaves the world hurtling towards a temperature rise far above the Paris Agreement goal of well below 2 degrees, preferably 1.5 degrees.Unconditional NDCs are estimated to give a 66 per cent chance of limiting global warming to about 2.6 degrees over the century.For conditional NDCs, those that are dependent on external support, this figure is reduced to 2.4 degrees.Current policies alone would lead to a 2.8 degrees hike, highlighting the temperature implications of the gap between promises and action.In the best-case scenario, full implementation of unconditional NDCs and additional net zero emissions commitments point to only a 1.8 degrees Celsius increase, so there is hope.However, this scenario is not currently credible based on the discrepancy between current emissions, short-term NDC targets and long-term net-zero targets.To meet the Paris Agreement goals, the world needs to reduce greenhouse gases by unprecedented levels over the next eight years.Unconditional and conditional NDCs are estimated to reduce global emissions in 2030 by five and 10 per cent respectively, compared with emissions based on policies currently in place.To get on a least-cost pathway to holding global warming to 1.5 degrees Celsius, emissions must fall by 45 per cent over those envisaged under current policies by 2030.For the 2 degrees Celsius target, a 30 per cent cut is needed.Such massive cuts mean that we need a large-scale, rapid and systemic transformation. The report explores how to deliver part of this transformation in key sectors and systems."It is a tall, and some would say impossible, order to reform the global economy and almost halve greenhouse gas emissions by 2030, but we must try," said Andersen."Every fraction of a degree matters: to vulnerable communities, to species and eco-systems, and to every one of us.""Even if we don't meet our 2030 goals, we must strive to get as close as possible to 1.5 degrees C. This means setting up the foundations of a net-zero future one that will allow us to bring down temperature overshoots and deliver many other social and environmental benefits, like clean air, green jobs and universal energy access."The report finds that the transformation towards net-zero greenhouse gas emissions in electricity supply, industry, transportation and buildings is underway, but needs to move much faster.Electricity supply is most advanced, as the costs of renewable electricity have reduced dramatically. However, the pace of change must increase alongside measures to ensure a just transition and universal energy access.For buildings, the best available technologies need to be rapidly applied. For industry and transport, zero emission technology needs to be further developed and deployed.To advance the transformation, all sectors need to avoid lock in of new fossil fuel-intensive infrastructure, advance zero-carbon technology and apply it, and pursue behavioural changes.Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
