RE:RE:methane news Furthermore, the capture and conversion of landfill gas to RNG can make a significant contribution to reducing the rate of climate change, particularly in the short to medium term, while also promoting sustainable waste management practices and supporting the broader transition towards a low-carbon economy. Essentially, this double impact - directly cutting greenhouse gas output by preventing the release of potent methane emissions, while also enabling a shift away from fossil fuels towards renewable energy - makes landfill gas capture and RNG production a powerful tool in comprehensive strategies to mitigate climate change impacts.
