This is the Committee on Climate Change’s (CCC) tenth statutory Progress Report to Parliament – an important moment to reflect on the UK's achievements in tackling climate change to date. 2018 also marks the tenth year since the Climate Change Act came into force and, with it, the creation of the CCC as an independent statutory adviser.
Executive summary: The future for gas networks is uncertain and contested, mainly due to the carbon dioxide (CO2 ) and methane emissions associated with natural gas systems. Gas networks are used in many countries to deliver natural gas to industrial, commercial and domestic consumers, supplying energy for a range of services, including space heating, water heating and cooking. Existing gas networks are extensive, with an estimated 2.8 million kilometres of gas transport pipelines globally.
