(MENAFN - The Conversation) Over the past few years there has been in clean energy investment – while fossil fuel assets are increasingly considered to be . Yet, on February 6, the European Investment Bank, the EU's long-term lending institution, voted to provide a to the controversial Trans Adriatic Pipeline (TAP).

The TAP is the Western part of a larger Southern Gas Corridor proposal that would ultimately connect a large gas field in the Caspian Sea to Italy, crossing through Azerbaijan, Turkey, Greece and Albania. And while gas might be cleaner than coal, it's still a fossil fuel.

So how does the EU's support for this major project fit in with its supposed goal of addressing climate change?

The proposed Trans Adriatic Pipeline will run nearly 900km from Greece to Italy. , Influencing investors

A key problem is the message this sends to the private sector, where renewable energy is increasingly seen as a good investment. Technologies once perceived as too risky and too expensive are now delivering worthwhile returns thanks to reduced costs and breakthroughs in energy storage. The price of electricity generated by solar, wind or hydro is now comparable with the national grid. Over the past decade, investor meetings have shifted from discussing whether the transition to a low carbon economy will start before 2050, to whether it will be completed in the same period.

But there is still not enough money being spent on renewables. While clean energy investment in 2017 , this is far short of what is needed to unlock the technology revolution necessary to tackle climate change. There is clearly a gap between what is required and what is being delivered.

The private sector will continue to invest significant capital into energy projects over the next few decades, so one issue facing policy makers is how to influence investors away from fossil fuels and . To really scale up investment into renewable infrastructure, – which investors .

By funding the Trans Adriatic Pipeline, the EU's investment bank is hardly signalling to the private sector that governments are committed to a green energy transition.

Risky business

If Europe really was to follow through and successfully switch to green energy – and such a transition is partially underway – then the pipeline project may even represent a risk to public finances.

Studies on climate change point to the need for a greater sense of urgency and ambition and, to stay within its 'carbon budget' under current agreed emissions targets, the EU needs to be .

So any large oil and gas infrastructure projects with investment returns beyond 2030 are saddled with risk. In just a decade or two, super-cheap solar and wind power could mean that gas pipelines such as TAP would no longer make financial sense and would become worthless '. Yet TAP backers are touting economic benefits for countries such as extending to 2068 – well beyond the date when Europe must entirely ditch fossil fuels.

The EU's official stance is to hail natural gas as a cleaner 'bridge fuel' between coal and renewables. But and the of methane (the primary constituent of natural gas) means that the Southern Gas Corridor's climate footprint may be . Abundant natural gas is also highly likely to .

For the first decade of this century Europe prided itself on leading the political debate on tackling climate change. Now, it appears to be losing its boldness. To drive through a new technology revolution, the public sector needs to lead from the front and take bold decisions about its energy strategy.

A gas pipeline is not a technology of the future. If California can release describing the importance of considering stranded assets during this energy transition, and New York City can announce plans to , then maybe it is time for the EU to turn off the TAP.
