An analysis of this year's Budget has found up to 80 percent of new initiatives have negative effects on the climate.
The New Zealand Institute of Economic Research commissioned the paper, and says New Zealand is lagging behind other countries in reviewing the impact of its policies on the environment.
The Institute is calling for standardised reporting on climate in Budget documents and legislative changes to the Public Finance Act.
Dr Murray Petrie peer reviewed the study - he's part of the OECD Expert Group on Green Budgeting.
Petrie spoke to Ingrid Hipkiss.
