It provides $757,000 to improve energy performance for households, including to introduce minimum energy standards for rental properties in 2022-23.

There will be almost $100,000 to help cool the city through the government's living infrastructure plan, which includes increasing Canberra's declining tree cover in residential areas.

More than $1 million will go towards installing electric vehicle charging stations and more than half a million to employ a dedicated climate change community leadership officer.

The government will also spend more than $800,000 to deliver its sustainable energy policy, including a new renewable electricity auction.

"The ACT's 100 per cent renewable electricity achievement highlights how we are a national leader in action against climate change," Climate Change Minister Shane Rattenbury said.

"But this is an ongoing battle and we must continually work to reduce our greenhouse gas emissions to zero, and to adapt to the changing climate.

WorkSafe ACT will receive $8.7 million over four years as part of the mid-year budget. The funding includes more than $700,000 this financial year to hire more inspectors and increase regulatory support staff.

"These extra resources will see the new WorkSafe ACT in the strongest position ever to monitor and enforce compliance with WHS legislation and regulations," Minister for Workplace Safety Suzanne Orr said.

She said the funding would help support the establishment of the new, independent WorkSafe ACT.

The funding announcements came after the government pledged $60 million for health funding to avoid jobs and service cuts last week, but it was not clear where or how the money would be spent.
