Issue 264 Climate change mitigation

With the effects of climate change increasingly apparent, the world must reduce, stabilise and extract greenhouse gases a concept known as ‘climate change mitigation’.

This March, ECOS explores a range of mitigation concepts, from methane reductions in mining, gaining public acceptance of new low emission technologies such as hydrogen, and how to ensure consistency of renewable energy supply during extreme weather events.

Science tells us that anthropogenic climate change is in effect. In order to limit the changes to our environments, economies and lifestyles, we must reduce greenhouse gas emissions from a number of sources. This is a huge task, so where should we concentrate efforts and what tools are at our disposal?

To decarbonise our energy systems, CSIRO is looking at the responsible innovation and social acceptance of hydrogen technologies. There are always challenges to the adoption of new technologies. Some of these challenges are technical or economic, but, for successful adoption, there also needs to be social awareness and acceptance.

Three technologies that mitigate methane emissions, either by destroying the gas or capturing it, are gaining the attention of miners seeking to reduce their emissions.
