K-Green Trust (KGT) third-quarter net profit rose 7.4 per cent to $3.8 million, while its revenue rose 0.3 per cent to $17.1 million.

The trust mainly invests in "green" infrastructure assets such as waste management, water treatment and renewable energy.

Revenue from operation and maintenance (O&M) rose 1.9 per cent to $12.8 million in the three months to Sep 30, compared to the same period a year earlier.

This was due to higher output from its Tuas plant and annual adjustments of O&M and power tariffs, to account for changes in the consumer price index and fuel price.
