This award reflects North Sky Capital's work in supporting solutions in waste, green energy, and the decarbonisation of the US economy.

The US impact investor describes 2021 as one of their "best years ever in terms of liquidity and distributions to our investors", with significant new investments alongside new progress on existing projects.

Last year their sustainable infrastructure team worked on investments that supported approximately 1 gigawatts of renewable power generating capacity.

As many landfill sites across the country approach capacity and the associated methane pollution hampers efforts to tackle climate change, North Sky sought to support sustainable infrastructure projects that convert municipal, agricultural, and food waste into renewable natural gas (RNG).

These include Project Golden Bear, a wastewater methane-to-RNG facility in Victorville, California, that is expected to reduce more than 6,000 metric tons of methane.

This is the equivalent of taking more than 30,000 cars off the roads or planting nearly three million trees, according to North Sky.

"We are honoured to be recognised for our sustainable infrastructure efforts, specifically regarding the areas of pollution reduction and waste management," says Scott Barrington, CEO of North Sky Capital. "We see tremendous opportunity to invest in the circular economy over the next several years.

"This series of renewable natural gas projects offers three big potential benefits: preventing methane from entering the atmosphere, resolving local food and dairy-farm waste problems, and providing investors with attractive returns."
