Romsey Abbey is a Grade 1 listed building in a largely Romanesque style with origins stretching back over 1.000 years. As such. it is a large space with no insulation and is heated with gas fired boilers that are over 40 years old. Despite its age it remains a vibrant centre of Romsey life (pop.15,000) for worship, cultural and civic events.   It is recognised by the Church of England as one of only 300 English Major Churches which are physically large and of "exceptional architectural and/or historic significance."

Since 2017, the Abbey has had a group of volunteers focussed on reducing the Abbey's environmental impact and on bringing environmental issues to the attention of the congregation. The group's activities were given greater impetus in 2020 when the Church of England General Synod voted for the whole Church of England to achieve net zero carbon by 2030. The vote recognised that the global climate emergency is a crisis for God's creation and unjust to the poor and future generations. This was further reinforced by the (2021 -2023) reports from the United Nations inter-governmental Panel for Climate Change (IPCC) which contained the following words:

"Some future (climate) changes are unavoidable and/or irreversible but can be limited by deep, rapid and sustained global greenhouse gas emissions reduction." (SR SPM B3)
