A new study by ETH Zurich researchers reveals that if Europe fails to immediately invest 302 billion euros in climate-\u200brelevant infrastructure, it will not reach its target of net-\u200bzero greenhouse gas emissions by 2050.<\/p>\n\n\n\n

Both the European Union and Switzerland have set themselves the goal of becoming climate neutral by 2050 and of reducing their greenhouse gas emissions to net zero. To achieve this target, major investments in power generation from renewable energies, electricity grids, storage capacities and other climate-\u200brelevant infrastructure are required. However, it has been unclear until now just how much investment will be necessary over the next 15 years and which areas are the most important.<\/p>\n\n\n\n

This gap in knowledge has now been filled by a meta-\u200bstudy conducted by ETH professor Bjarne Steffen and Lena Klaa\u00dfen, which was recently published in Nature Climate Change<\/em>. The authors conclude that reaching the net-\u200bzero target will be jeopardised if an annual 302 billion euros fail to flow into climate-\u200brelevant infrastructure in Europe over the next two years.<\/p>\n\n\n\n

A third more investment needed<\/h5>\n\n\n\n

‘Investment in green infrastructure needs to urgently increase by 87 billion euros per year compared with the levels of recent years. This is an increase of more than one third,’ explains first author Klaa\u00dfen, who is a doctoral student at ETH Zurich\u2019s Climate Finance and Policy Group. Although the money is readily available \u2013 given the size of the European equity and bond markets \u2013 the main challenge is to put the necessary political policies in place quickly enough to ensure that capital flows into the right projects.<\/p>\n\n\n\n

The ETH researchers built on 56 relevant technology and investment studies from academia, industry and the public sector. They focused on the countries of the EU, but also took into account data on the UK, Norway and Switzerland. The overall European trends are therefore also relevant for Switzerland.<\/p>\n\n\n\n

Three areas are particularly important<\/h5>\n\n\n\n

The most dramatic increase in the need for investment is in power generation from renewable energies. ‘In order to drive forward the decarbonisation of all areas of life, around 75 billion euros needs to be invested in solar and wind power plants in the coming years. This is 24 billion euros more per year than in the recent past,’ adds Steffen.<\/p>\n\n\n\n

The situation is similar in the expansion of distribution networks and the railway. In these areas, too, 40 to 60 per cent additional financial flows are required compared to the 2016 \u20132020 period in order to expand electrification and to shift traffic from road to rail.<\/a><\/p>\n\n\n\n

Ukraine war reinforcing trends<\/h5>\n\n\n\n

According to the authors, the war in Ukraine is reinforcing these trends further: ‘In order to import as little gas as possible from Russia, Europe would have to invest around 10 billion euros more per year in solar energy and wind power. In comparison, significantly less investment \u2013 around 1.5 billion euros per year \u2013 is needed in additional natural gas infrastructure such as LNG terminals,’ says Steffen.<\/p>\n\n\n\n

According to the ETH study, fossil fuels such as coal, oil and gas are likely to tie up less capital in future in Europe. The investment required in conventional power plants in particular is set to fall by 70% within the space of a few years. <\/p>\n\n\n\n

Tailoring regulation to different sectors<\/h5>\n\n\n\n

What can policymakers do to expedite the increase in capital made available for the expansion of green infrastructure? ‘Political measures should be tailored to funding in those sectors where there is the greatest need for investment,’ explains Klaa\u00dfen. This is not a matter of course today, she says. For example, existing regulations in the EU focus on identifying sustainable securities, despite the fact that important climate-\u200brelevant infrastructure is not at all financed via the equity markets. <\/p>\n\n\n\n

The expansion of renewable energies, in contrast, is often made possible by private investors such as pension funds and banks. The public sector should minimise their risk through revenue guarantees and by making approval procedures as quick and predictable as possible. Public investment in new technologies such as CO2 <\/sub>storage can also help to encourage private investors to venture into these areas.<\/p>\n\n\n\n
