Dark green
From ACT Wiki
Sustainability - green strategies, projects and solutions - Loan Market Association (LMA).
'Dark' green is a colloquial term, meaning relatively more radical and far-reaching green strategies, projects and solutions, compared with 'light' green ones.
The Loan Market Association (LMA) defines dark green as referring to projects and solutions that correspond to the long-term vision of a low carbon and climate resilient future.
The LMA defines dark green strategies as strategies in which green and sustainable principles and practices are fully embedded in - and direct - the strategy and operations of an organisation.
