A POSTnote on digital skills for life will discuss the digital skills required for everyday life and employment, why parts of the population may lack these skills and which groups are most affected. It will consider the impact of the skills shortage on individuals and the economy as well as strategies to improve the population’s digital skills. Provisional start date: January 2021.

Decarbonising the Gas Network (449 KB, PDF)
The Climate Change Act (2008) requires an 80% reduction in greenhouse gas (GHG) emissions relative to 1990 levels by 2050. The UK is on track to meet short-term emissions targets, but is unlikely to meet longer term targets without additional policies. While emissions from electricity production have fallen significantly, there has been much less progress in reducing emissions from heating.
The gas network supplies natural gas to consumers for heat, and could in future supply alternative gases that do not contribute to climate change. This note looks at the prospects for ‘decarbonising’ the gas network, by supplying biomethane and hydrogen in place of natural gas. It covers their production and supply, carbon emissions and costs, and technical and policy challenges.
Key points in this POSTnote include:
- The UK needs new policies on low carbon heating to meet its emissions reductions targets under the Climate Change Act.
- The gas network delivers more than twice the energy of the electricity grid and supplies 23 million consumers. Supplying hydrogen and biomethane in place of natural gas could reduce emissions.
- Biomethane from waste already supplies some gas to the network and could be increased. The amount of available waste material limits future supply potential to 5-20% of current gas demand.
- There is also potential to supply parts of the network with hydrogen in future, but this is reliant on cost reductions, uptake of carbon capture and storage in the UK, and significant changes in network infrastructure.
An update to this note was published on 27 Nov 2017.

Evolving life sciences and agricultural research approaches may have a decreasing need to access physical resources in future, such as plant seeds or viral material. Information and genetic data may be all that is required for commercial exploitation of biological resources. This POSTnote summarises the challenge this creates for international discussions on the governance of genetic resources and the possible options for addressing these.

Plastic packaging waste has become a key consumer concern. In the UK, over 2.2 million tonnes of plastic packaging enter the consumer market each year. Much of this is used in the food sector because plastic packaging is cheap, light to transport, hygienic, and can be used to extend the product’s shelf-life. In the UK around 46% of plastic packaging is collected for recycling, mostly through local authority collections. However several issues with the current systems of plastics recycling persist. This POSTbrief reviews proposals to Defra and HM Treasury to improve plastics recycling in the UK .
