Prime net zero ratings | Insight Investment

The Prime net zero ratings aim to categorise corporate and sovereign issuers according to their alignment with achieving net zero by 2050. For corporates, this is based on the materiality of a company’s sector to achieving net zero, and the maturity of the company itself with regard to achieving net zero targets. For sovereigns, this is based on distinguishing between developed economies, and developing and emerging economies; and the maturity of the country’s progress towards achieving net zero.

The five Prime net zero ratings are as follows:

• Not aligned
• Committed
• Aligning
• Aligned
• Achieving

The ratings cover over 13,500 corporate issuers around the world, and 70 sovereign issuers (as at 31 December 2025).

The Prime net zero ratings enable dedicated solutions and portfolios with specific parameters to ensure investments are aligned with net-zero goals, for clients seeking such strategies.

Our portfolio managers and analysts may use the Prime net zero ratings to inform their engagements with corporate and sovereign issuers, in line with commitments set out alongside relevant investment strategies, and Insight’s net-zero ambition.

Insight's mission is to offer investors a different approach to achieving their investment goals; one that prioritises the certainty of meeting their chosen objectives in contrast to a traditional focus on maximising return and minimising volatility.

Climate change is a significant challenge which many investors are seeking to navigate. We aim to be sensitive to the needs of our clients by ensuring that our policies and practices can accommodate a range of investment preferences and customised mandate requirements.
