We can, and must, do more to cut emissions

It’s great to see the Cromwell Pool closed.

That’s to change out the heating system.

They are replacing the LPG system with a new, low-carbon option.

This is just the sort of action needed to reduce greenhouse gas emissions in the region. Industrial heat pools, schools and hospitals largest source of emissions for New Zealand, after agriculture and transport.

A new report this week said coastal areas had less time than expected to deal with sea-level rise.

Experts are now predicting that the next 10 to 20 years could see 30cm of sea-level rise in places such as Wellington and Auckland.

By reducing our emissions here, we contribute to national and international efforts to reduce the impacts of climate change.

In May, the Government will release a plan for the next few years to reduce greenhouse gases in New Zealand.

This plan is the next step in a long process.

There have been consultations and reports, all trying to pin down what is necessary and what is possible.

The necessary part has become very clear.

Last month, the Intergovernmental Panel on Climate Change (IPCC), the international body that reviews the science on climate change, produced another report.

It said again that the world needed to reduce emissions, and emphasised that methods and technologies were available.

Figuring out what changes are possible is key.

This problem is the same economic challenge we always have: how to do more with less.

If you are running a business, you try to reduce your costs but still make the same revenue. Or you try to expand the business while keeping costs under control.

We are constantly told to work smarter not harder. The focus on productivity is really a focus on efficiency.

Time is a resource, money is a resource. We don’t want to waste them.

Reducing emissions is also about efficiency. Fossil fuels are a resource, the environment is a resource. We have discovered that it is dangerous to waste them.

And although an inefficient business can eventually go bankrupt, we probably don’t want to find out what a bankrupt global climate looks like.

So good on the Cromwell Pool for changing its heating.

It’s a great reminder that we all should do better, and that we can.
