Gisborne’s emissions on a downward slide

GISBORNE’S emissions profile from Statistics New Zealand shows the region’s total emissions from households and industry are going down.

The data shows that Gisborne’s emissions have decreased from 1460 kilotonnes (kt) of carbon dioxide equivalent (Co2-eq) in 2007, to 1301kt in 2018.

The regional emissions estimates from Statistics NZ are part of the department’s environmental-economic accounting programme.

They are designed to inform on the regional influences of industry-level emissions estimates and are based on the availability of greenhouse gas inventory data which goes up to 2018.

“We are exploring the possibility of producing a quarterly emissions series, but this will not have a regional breakdown,” a Stats NZ spokesperson said.

Gisborne’s primary industry emissions, which in the report include agriculture, forestry, fishing and mining, have decreased from 1262kt to 1106kt.

Emissions from goods-producing industries, which include manufacturing, electricity, gas, water, waste services and construction, have increased from 61kt to 71kt.

Service industry emissions including transport, postal and warehousing have decreased from 51kt to 43kt.

Total emissions from all industries in the region have decreased from 1373kt to 1219kt.

Sources of Co2-eq such as agriculture have declined from 1147kt to 969kt. Energy emissions have increased from 229kt to 237kt.

Industrial processes and product use emissions have increased from 8kt to 14kt and waste emissions have increased from 76kt to 83kt.

Gas emissions, such as carbon dioxide equivalents, carbon dioxide, methane and nitrous oxide have all decreased since 2007, except for fluorinated gases which have doubled from 6kt to 12kt.

The Herald took these statistics to the Gisborne District Council with questions about each of the categories and reasons for the increases and decreases.

“The data is very complex and to give detailed answers we would need to investigate it more thoroughly,” GDC principal scientist Dr Murry Cave said.

“For example, the statistics aggregate forestry, fishing, mining and agriculture as primary industries. But figures for each of those sectors will vary, so it is difficult to get a clear view of the numbers,” Dr Cave said.
