There are three main ways New Zealand is responding to climate change - an emissions trading scheme and emissions reduction goals, renewable energy maximisation, and energy efficiency programmes and targets. These responses will be key to achieving our commitments under the Paris Agreement.

The ETS puts a price on carbon emissions, providing an incentive for people to reduce emissions and plant forests to absorb carbon dioxide.
Certain sectors, including the oil and gas industry, are required to purchase 'New Zealand units' to offset their emissions.
An emission unit is one metric tonne of carbon dioxide, or the equivalent of any other greenhouse gas, therefore making businesses pay for their greenhouse gas emissions. This encourages them to reduce emissions through changing their practices or investing in new technology. This is why putting a price on emissions is widely recognised around the world as the best way to lower emissions at least cost.
Forestry owners can sell New Zealand units to emitters, because trees absorb carbon. The price of these New Zealand units is set by the market. This should result in increased incentives to plant forestry.
The ETS now has a 'cap' which is maximum total allowable amount of emissions allowed.

Most of New Zealand’s renewable energy is used for electricity generation. In 2020, a total of 80% of electricity generation came from renewable resources, increasing from 75.1% in 2013.
Unlike many other countries, New Zealand’s electricity generating industry is dominated by renewable energy.
The downside of this success is New Zealand is left with little room to achieve significant emission reductions in the electricity generation industry.

As a country, we use about 2% more energy every year. We could save about 20% of that demand (or $2.4 billion a year) by using energy more efficiently.
