There is no formal decision yet for the mail to be distributed every other day. But PostNord's calculations show that if the reform is implemented, carbon dioxide emissions will increase.

- With current legislation, when 95 percent of the letters are due within two days, a two-day dividend will mean a certain increase in carbon dioxide emissions, states the company's sustainability manager Sofia Leffler Moberg.

She says that the reason is that Postnord must have more routes in operation than before in order to live up to the current legislation that the letters should arrive within two days.

- Transport by air generates more emissions than transport by car or train.

- None of us at Postnord are satisfied that emissions will increase from any business change, as our goal for all changes is that the climate impact should decrease or at least not increase, says Leffler Moberg.

Secret numbers

However, Postnord does not want to publish any figures showing what "a certain increase in carbon dioxide emissions" means. However, the Group's target is a 40 per cent reduction by 2020 at the Group level. The Swedish part of the company has a goal of reducing emissions by 25,000 tonnes of carbon dioxide in 2019.

Now the company is working on creating a changed postal legislation so that the letters do not have to be delivered within two days. Then fewer routes are required, which means a reduction in emissions.

Dividend decisions are delayed

At the same time, Postnord is secretive about when a formal decision on a so-called two-day distribution will be made.

Group management wants every two-day dividend to be implemented. What's the matter?

- It's a big production device. There may be occasional details. It must take the time it takes because the quality must not suffer, says Henrik Ishihara at PostNord's press service.

Your calculations with regard to the climate issue show that every two-day distribution means a certain increase in the total emissions if you are to follow the law on how to distribute the item urgently. Is that the reason why a decision is delayed?

- I do not want to go into why it is delayed. There are a number of variables to consider, says Henrik Ishihara.

- In our world there is no delay. We continue to work to ensure that every two-day distribution will be introduced without compromising quality.

PostNord's CEO Anne-Marie Goldshol tells SVT that the company will continue to work on the issue and prepare for a test later on.
