Brussels, July 15 : The European Commission has unveiled a comprehensive roadmap for realising the European Union's (EU) ambitious target of reducing its net greenhouse gas emissions by at least 55 per cent by 2030 and to become climate-neutral by 2050. The massive package of legislative updates, dubbed "Fit for 55", was presented by the EU's climate policy chief Frans Timmermans here on Wednesday, who said that the EU aimed to "give humanity a fighting chance", reports Xinhua news agency. "We're going to ask a lot of our citizens. We're also going to ask a lot of our industries, but we do it for a good cause," he told a news conference. The plan is intended to transform the bloc's economy from dependency on fossil fuels to a world of net-zero emissions, which is expected to effectively end new petrol and diesel vehicle sales by 2035. In addition, from 2026, road transport will be covered by emissions trading, putting a price on pollution, stimulating cleaner fuel use and re-investing in clean technologies. "Europe is now the very first continent that presents a comprehensive architecture to meet our climate ambitions," European Commission President Ursula von der Leyen said. "We have the goal, but now we present the roadmap to how we are going to get there," she added. The key proposals include a tax on aviation fuel, a 10-year tax holiday for low-carbon alternatives and a so-called carbon border tariff, which would require manufacturers from outside the EU to pay more for importing materials like steel and concrete. There are also more ambitious targets for expanding renewable energy with the aim of producing 40 per cent of the bloc's energy from wind, wave and solar sources by 2030, as well as a requirement for countries to renovate buildings that are not energy efficient. A new Social Climate Fund will help citizens mitigate the costs for those most exposed to changes to ensure that the transition is fair. It will provide 72.2 billion euros ($85.4 billion) over seven years in funding for the renovation of buildings, access to zero and low-emission mobility, or even income support. The draft proposals still need to be approved by the bloc's 27 member states and the European Parliament. "Change on this scale is never easy, even when it is necessary. And for that reason, there are some who will say we should go slower, we should go lower, we should do less," von der Leyen said. "But when it comes to climate change, doing less or doing nothing literally means changing everything," she said. /IANS
