Regeneros' ethos and mission is to create a built environment that regenerates the planet, whilst simultaneously promoting the health and wellbeing of occupants and aligning with our customers' core business objectives.

The United Nations had reported as early as 2018 stating that a 2 °C temperature increase would essentially lead to climate change conditions that would seriously affect humanity's living conditions including extreme weather, rising sea levels, flooding and others. Limiting global warming to 1.5 °C compared with 2 °C would reduce these climate change impacts to manageable levels.

The other key finding was that meeting a 1.5 °C (2.7 °F) target is possible but would require "deep emissions reductions" and "rapid, far-reaching and unprecedented changes in all aspects of society." In line with this, the shift from traditional approaches to more progressive ones based not only on sustainability, but on regeneration is critical to maintaining a planetary environment that the human species can survive and thrive in.

At a regional and national level, most nations have duly incorporated sustainability into their future vision, with many including the UK targeting a carbon neutral economy by 2050. Despite these commitments, 2020 tied with 2016 as the hottest year on record, and United Nations' research shows that global investment in fossil fuels continues to be substantially higher than investment in climate change technologies including renewables.
