Light green
From ACT Wiki
Sustainability - green strategies, projects and solutions - Loan Market Association (LMA).
'Light' green is a colloquial term, meaning relatively less radical and less ambitious green strategies, projects and solutions, compared with 'dark' green ones.
The Loan Market Association (LMA) defines light green strategies as strategies in which green and sustainability factors are not central to an organisation’s strategy and operations, but rather additions to a strategy that does not have a green and sustainable vision and purpose at its core.
In this context, an example of light green project might be an environmentally friendly one that won’t change the long-term outlook on its own, such as more efficient fossil-fuel infrastructure.
