Countries will need to accelerate the phase-out of coal, curtail deforestation, speed up the switch to electric vehicles, and encourage investment in renewables.
One not-so-obvious area that can play an important role in tackling carbon dioxide emissions is the chemical industry.
In a new Loughborough University video, Professor Jin Xuan, an expert in low carbon processes and the Head of the Department of Chemical Engineering, discusses why countries must turn their focus towards this sector.
“Carbon dioxide emissions from various industrial sources account for 16% of the UK’s total emissions and unfortunately, the chemical sector is one of the highest carbon dioxide emitters among all the UK’s industrial sectors and it is very hard to de-carbonise it”, says Professor Xuan.
“Most of our daily materials and products are essentially made from oil and gas – such as plastic bags – but there are also some not so obvious examples, like my lab coat, which is essentially made from petroleum oil.
“This high reliance on fossil fuels generates serious problems and it means a high amount of carbon is embedded in these products.
“At the end of use, we send these products and materials to the incinerator and all the carbon dioxide is released back to the environment, which causes huge environmental issues and climate change effects.”
Professor Xuan says the solution is a ‘circular economy approach’ and he is the Director of the UKRI Interdisciplinary Centre for Circular Chemical Economy – a new £4.3m centre, involving seven UK universities, that aims to improve the sustainability of the UK’s chemical industry.
The ambition of the Centre is to transform the UK’s £32 billion chemical industry into a fossil-independent circular industry by developing sector-wide solutions for the efficient recycling and recovery of chemical resources, such as olefins.
The Centre will deliver interventions and scientific innovations at all levels, starting from the development of new disruptive technologies, their integration into existing processes and evaluation of whole system impacts, to the identification of non-technical barriers and opportunities, and how they can be overcome/realised.
Of the Centre’s importance, Professor Xuan said: “We need to fully recycle and reuse all the waste and emitted carbon dioxide and use it to make fresh chemicals; I believe only by doing this will the chemical industry survive in this great transition towards net zero.
“Our vision is to use a whole system approach to deliver innovative solutions that can be scaled up and create a circular economy for the UK’s chemical industry.
“We are very proud to be a national leader, bringing together stakeholders – such as business, government, and the public – to enable a great transition towards a circular economy, which we believe will play a role in the net zero future to be outlined at COP26.”
