What is it about?
Geoscience is the study of the earth – what it is made of, and how natural processes work. There are many ways it can help us reduce our use of carbon – for example, hydropower, which uses the natural flow of water generate electricity, is one of the most common types of renewable energy. Another example is geothermal energy. This is when heat from beneath the earth’s surface is used for heating, cooling, or to generate clean electricity. Geoscience has also helped us develop carbon capture and storage (CCS). This where carbon dioxide is stored underground. This stops it being released into the atmosphere, where it would cause global warming.

Why is it important?
At COP 21 in 2015, 197 countries agreed to limit the increase in global temperatures to less than 2ºC. However, judging by our current pace of progress, we are far from achieving this objective. We need to make more use of geoscientific energies and technologies. This will mean increased demand for geological materials. We need better regulatory and licensing frameworks to manage that demand. KEY TAKEAWAY: Governments and other decision makers need to understand the role geoscientific solutions can play in reducing carbon emissions.

A new ‘green’ coating for flame-retardant wooden buildings
Wood is a more environmentally friendly building material than many alternatives, but fire risk needs to be managed in a way that is also environmentally friendly. This new biogel could be an important part of helping us build more sustainably.
The balloon that can monitor climate change
This new technology will make it easier for scientists to gather more information about greenhouse gases in the atmosphere. This helps us to monitor climate change. The more we know about how gas levels are changing, the more we can be sure of whether our efforts to tackle climate change are working.
Fighting Climate Change: The New Corporate Social Responsibility
Companies and countries are now expected to protect the environment as much as they would protect human rights. They need to be ready to obey new laws in this area.

The arctic climate crisis and its ‘chilling’ implications
The Arctic ice melting crisis is of immense immediate importance and re-quires more than just policy changes. Focused research on unconventional technological solutions to stop the melting is urgently needed.
