Climate action
Today we are seeing climate change in action, increased concentrations of atmospheric greenhouse gases have led to a rise in sea levels, temperatures, and extreme weather patterns. Researchers have acknowledged the pivotal role microorganisms in producing sustainable biofuels, increasing carbon sequestration via soil microbes and reducing methane emissions in landfill sites. Microbial innovation will be vital in moving towards a low carbon economy.
