Figure 4: Ministry for the Environment CO2 equivalent emissions

In 2005/06, the Ministry generated a minimum [Note that while calculated in accordance with international Greenhouse Gas (GHG) accounting protocols, in common with many organisations reporting on their CO2 impact, our CO2 figure represents a minimum only.] of 733.6 tonnes of CO2 equivalent emissions, a six percent increase on the 2004–2005 figure of 691.2 tonnes. The Ministry’s CO2 equivalent emissions per staff person decreased by 4.5 percent, to 2.9 tonnes per staff member from the 2004–2005 emissions of three tonnes.
The increase in total emissions is primarily due to the fact that we can now calculate CO2 emissions from energy use for heating, ventilation and air conditioning (HVAC) in Environment House, where previously we could not measure a significant proportion of our energy use. The increase is due also in part to our increased kilometres travelled in international flights and the addition of a hybrid vehicle to our vehicle fleet.

| 2005/06 | 2004/05 | 2003/04 | 2002/03 | |
|---|---|---|---|---|
| CO2 equivalent emissions per staff member (tonnes) | 2.9 | 3.0 | 3.0 | 2.6 |
| Key targets and commitments | Progress at 30 June 2006 |
|---|---|
| Monitor our CO2 equivalent emissions to understand and report back on the reasons for any fluctuation year to year. | Ongoing: Continue to monitor our CO2 equivalent emissions throughout 2006–2007. |
