The researchers argue that if global carbon limits were introduced that would eliminate concerns over the 'rebound effects' so that ICT-enabled efficiencies could be realised without additional carbon costs. The researchers recognise that several of the world's technology giants have made statements on reducing their climate footprint, however they argue that many of these pledges are not ambitious enough and industry self-regulation may not be sufficient to bring about the emissions reductions needed to reach net-zero by 2050.

Clear detail is required on a sector by sector basis of the emissions savings that ICT is expected to deliver, underpinned by transparent evidence that includes all related emissions.

With competing demands on ICT such as workplace communications, leisure, Internet of Things, AI and bitcoin mining, in order to prevent run-away data demand, societies may need to consider prioritising some ICT uses above others.

ICT organisations need to have legally binding net zero targets that also cover their supply chain emissions.

Unprecedented co-ordination across the ICT sector and policy makers is needed to formulate a plan to achieve net zero by 2050.

The researchers point out that to achieve net zero by 2050 - a target the planet needs to meet in order to keep global warming below 1.5☌ - then: Our work tries to shine a bit more light on that important question." But it's relationship to carbon reduction may not be as straightforward as many people assume. Professor Mike Berners-Lee from Small World Consulting said: "We know that ICT has an ever growing role in society and brings efficiencies to almost every corner of the global economy.

This could be partly due to so called 'rebound effects' where increased efficiencies result in increased demand. In addition, ICT has driven wide-ranging efficiency and productivity improvements, but, critically, global greenhouse gas emissions have risen inexorably despite all this. That over the years as ICT has become more efficient, ICT's footprint has taken up a greater proportion of global emissions. However, the researchers argue that historical evidence proves the opposite. It has often been cited, and put into policy calculations, that ICT and computing technologies will lead to greater efficiencies across many other sectors, leading to savings in net greenhouse gas emissions. In their new paper 'The real climate and transformative impact of ICT: A critique of estimates, trends and regulations' published today by the journal Patterns, the researchers looked at two central issues - ICT's own carbon footprint, as well as ICT's impact on the rest of the economy. In addition, the paper warns that new trends in computing and ICT such as big data and AI, the Internet of Things, as well as blockchain and cryptocurrencies, risk driving further substantial growth in ICT's greenhouse gas footprint. Although like for like comparisons are difficult, these figures would suggest ICT has emissions greater than the aviation industry, which are around 2 % of global emissions. The researchers argue ICT's true proportion of global greenhouse gas emissions could be around 2.1-3.9% - though they stress that there are still significant uncertainties around these calculations.

The researchers point out that some of these prior estimates do not account for the full life-cycle and supply chain of ICT products and infrastructure - such as: the energy expended in manufacturing the products and equipment the carbon cost associated with all of their components and the operational carbon footprint of the companies behind them the energy consumed when using the equipment and also their disposal after they have fulfilled their purpose. A team of researchers from Lancaster University and sustainability consultancy Small World Consulting Ltd claim that previous calculations of ICT's share of global greenhouse emissions, estimated at 1.8-2.8%, likely fall short of the sector's real climate impact as they only show a partial picture.
