The Office of Energy and Climate Change (OECC) was established in the Treasury Cluster in April 2022.

OECC is led by Acting Deputy Secretary of Energy, Climate Change and Sustainability (ECCS) Andrew Lewis, and Energy Corporation of NSW (EnergyCo) Chief Executive James Hay, who each report to the NSW Treasury Secretary.

One of the central planks of NSW's economic policy agenda is ensuring the state leads the way on climate change and seizes the opportunities from the transformation to a new low-cost, clean energy economy. Establishing OECC within the Treasury Cluster enables the government to harness and leverage synergies and expertise across Treasury – and it opens up exciting new opportunities for Treasury to play a highly influential role in responding to the significant economic and environmental challenges.


The AdaptNSW website has been produced by the NSW Government to inform and empower communities, businesses, households and government to adapt to climate change.

Action by all sectors of society on climate change continues to grow as the effects and risks are becoming more evident, and we are confronted with more extreme weather events.

The AdaptNSW website is a source you can trust, that provides relevant, localised information to keep you informed and help you adapt to climate change.


Climate and Energy Action

The Climate and Energy Action website helps the people of NSW save money and reduce their climate and energy impact.

It provides easy-to-access information and opportunities to support sustainable choices for households, businesses, or communities.

Find out how the NSW Government is leading the way through our policies and actions to: 

  • reduce our emissions to net zero by 2050
  • transform our energy sector and accelerate our renewable energy infrastructure 
  • ensure energy affordability and reliability for the people of NSW.

EnergyCo NSW

EnergyCo is coordinating the development of the first five Renewable Energy Zones (REZs) and critical infrastructure across New South Wales. As the Infrastructure Planner for these REZs, EnergyCo works closely with communities, investors and industry to ensure the REZs are in the long-term interest of energy consumers, local communities and industry in NSW.

EnergyCo’s purpose is to maximise the benefit of the transition to renewable energy across New South Wales.


GreenPower is 100% renewable energy available for households and businesses through most energy retailers in Australia.


NABERS, which stands for the National Australian Built Environment Rating System, is a simple, reliable sustainability rating for the built environment.

Like the efficiency star ratings on fridges or washing machines, NABERS provides a rating from one to six stars for buildings efficiency across energy, water, waste and the indoor environment.

This helps building owners to understand their building’s performance versus other similar buildings, providing a benchmark for progress.
