Scientists urge global action after ‘historic’ US climate bill
The Senate of the United States the worlds largest greenhouse gas emitter has passed unprecedented legislation aiming to cut emissions 40 percent by 2030. Scientists welcomed the passing of US President Joe Bidens historic climate bill while calling for other major emitters namely the European Union to follow suit and implement ambitious plans to slash emissions. The bill, which would see an unprecedented $370bn invested in cutting United States emissions 40 percent by 2030, should provide a launch pad for green investment and kick-start a transition towards renewable energy in the worlds largest greenhouse gas emitter. It passed the Senate on Sunday night after months of arduous negotiations and only after a number of tax and energy provisions were tacked on to Bidens original proposal. Michael Pahle, from the Potsdam Institute for Climate Impact Research, said the bill was particularly relevant to EU lawmakers, who he said were on the verge of adopting the worlds most ambitious climate policy in the form of the blocs Fit for 55 plan . The EUs policy can only succeed economically and politically when major emitters and trade partners take similar action, said Pahle. Especially in face of the changing geopolitical landscape, US-EU cooperation is key and the bill an important enabling factor. The EU initiative which envisages a 55-percent emissions fall by 2030 has no set budget as yet. But a recent assessment found member states would need to spend 350 billion euros ($357bn) more each year than they did between 2011-2020 in order to hit the climate and energy targets. Simon Lewis, professor of global change science at University College London, said the US bill showed how lawmakers can advance climate legislation while responding to voters short-term concern over fuel-price inflation. Its really important that the worlds largest economy is investing in climate and doing it as part of a package to generate jobs and a new, cleaner, greener economy, Lewis said. Part of that is a package tackling inflation. I think that shows the world how to get climate policy passed, by hitching it to things that really matter to ordinary people, to make sure its part of an overarching package to make life better for people. The independent Rhodium Group think-tank said the historic and important bill officially the Inflation Reduction Act would reduce US emissions by at least 31 percent by 2040, compared with 2005 levels. However, it said with favourable macroeconomic conditions including increasingly high fossil fuel prices and cheap renewables a 44-percent emissions drop was possible. The cost of living is here partly because we didnt get out of fossil fuels early enough , said Lewis. This bill means that the transition away from fossil fuels is about to speed up. Eric Beinhocker, director of the Institute of New Economic Thinking at the Oxford Martin School, said the US bill would lead to a massive increase in clean technology and would drive the cost of renewables down even further. This is particularly important when the world is suffering not just from the climate effects of fossil fuels but also from their skyrocketing costs, he said. The legislation provides millions to help conserve forests and billions in tax credits to some of the countrys worst-polluting industries to accelerate their transition to greener tech. It almost didnt happen, however, with the bill delayed for months after Democrat Joe Manchin blocked Bidens more expensive Build Back Better infrastructure plan. Pahle said a failure by the US to agree on an ambitious emissions-cutting plan would have been a major drawback on the viability of the Paris Agreement . The 2015 accord enjoins nations to work to limit global temperature rises to well below 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels and envisages a safer 1.5C (2.7F) heating cap. With more than 1.1C of warming so far, Earth is already being buffeted by extreme weather such as drought and storms supercharged by rising temperatures. Although acknowledging the bill represented progress, scientists were quick to stress it was far from perfect. Michael Mann, director of Penn States Center for Science, Sustainability and the Media, said the bills commitment to building new gas pipelines was a step backwards. Its difficult to reconcile a promise to decarbonise our economy with a commitment to new fossil fuel infrastructure, he said. Radhika Khosla, from the University of Oxfords Smith School, said only action on a global scale could achieve the emissions cuts necessary to stave off the worst impacts of global heating. The effects of climate change are being felt by all of us, she said. This summer alone parts of the globe as disparate as China, the UK and Tunisia all saw record-breaking, deadly heatwaves. Lasting change will require ambitious action from all of us as well.
