Greenhouse Gas Emissions

The reduction and management of greenhouse gas emissions forms a key part of WEL’s Sustainability Programme.

By achieving the baseline numbers for our greenhouse gas emission profile, WEL now has an improved understanding of these emission sources. With total WEL emissions (excluding subsidiaries) of 1428 tCO2e (tonnes of CO2 equivalent) this allows us to identify targets within the greenhouse gas reduction plan.

The initial Toitū carbonreduce audit confirmed that more than 85% of WEL emissions come from diesel use in vehicles and generators; and electricity use in the offices and network sites. Addressing these areas for net relative reductions, this year, is a key focus of our greenhouse gas reduction plan.

As part of our pledge to reduce our relative carbon footprint, we’ve become part of the Climate Leaders Coalition. We’ve also committed to the Paris Agreement target of keeping global warming below 2 degrees and further pursue efforts to limit the temperature to 1.5 degrees.

While the greenhouse gas reduction plan specifies targets for efficiencies and economies in operating WEL vehicles, in electricity consumption and in personnel behaviours, other initiatives are being introduced across the business to support WEL’s Sustainability Programme.
