What Green Knight does

Green Knight Sustainability Consulting Ltd is a privately-held UK sustainability advisory firm founded in 2017 and headquartered in Bakewell. The company helps organisations across the agri-food sector and allied industries develop and implement ESG strategies, carbon footprinting programmes, lifecycle assessments, double materiality assessments, and sustainability reporting. Its client base spans UK and international manufacturers, retailers, trade bodies, third-sector organisations, utilities, government bodies, and universities, with case-study work covering food and beverage, construction, packaging, infrastructure, agri-feed and education sectors.

The firm's core offerings are organised into four service pillars: sustainability strategy consulting; lifecycle assessment, carbon and net-zero services (built on the market-leading Ecoinvent 3.10 database and ISO/BSI/PAS standards); data, analysis and reporting; and technical support and research (including biodiversity net-gain assessments and CBAM compliance guidance). These advisory services are complemented by a productised training portfolio comprising ISEP-approved Lifecycle Assessment and Double Materiality workshops, in-house group training, and bespoke programmes on topics from net zero and circular economy to systems thinking and the GWP* metric. The team is led by founder Gavin Milligan, a doctorate-level practitioner with over 30 years of operational Board-level and academic experience and UKAS-trained validation credentials.

Green Knight generates revenue entirely through professional services: bespoke consulting engagements priced on a quote basis, scheduled public training workshops at fixed per-delegate prices (£1,200+VAT for LCA, £500+VAT for Double Materiality), in-house group training, and fee-based speaking, chairing, consortium-building and event facilitation. The firm has no external institutional funding, operates without disclosed subsidiaries or acquirer relationships, and reaches clients through direct engagement, professional referrals, academic and trade publications, and speaking engagements at industry conferences and universities.
