New Zealand Emission Unit Prices in the NZ Emissions Trading Scheme 2010 to date.

Description

This data repository provides a reproducible public domain data series of mean monthly spot prices of the New Zealand emission unit (or "NZU"), the domestic emission unit in the New Zealand emissions trading scheme.

New Zealand has had an emissions trading scheme since 2009. Although private sector carbon brokers display current and some historic trading prices for sales of the NZ emission unit (the "NZU"), there is no public data series of the New Zealand carbon price.

There is a chart of the data at Wikimedia Commons.

Data Preparation

Requirements

Data preparation was performed with the R programming language, R version 3.3.3 (2017-03-06) with the RKWard 0.6.5 IDE running on an i586-pc-linux-gnu (32-bit), Debian GNU/Linux 9 (Stretch) MX-17 operating system on a Dell Inspiron 6000 laptop.

Processing

The raw price data has been manually 'web-scraped' and recorded in the file NZU-weekly-prices-data.csv.

Run the R script NZU-monthly-mean.r from a directory to download and process the raw data into a mean monthly time series. This is then written to a file nzu-month-price.csv.

Data files at Google sheets

1. The raw data: nzu-weekly-prices-data.csv.

2. The edited price data with the addition of a month column: nzu-edited-raw-prices-data.csv.

3. The mean monthly price data: nzu-month-price.csv.

4. The mean weekly price data: weeklymeanprice.csv.
