employees are calling the contents of the company’s annual environmental report into question, including the retail giant’s claim to have reached its goal to become a 100% renewably powered company seven years ahead of schedule.

The online retail giant published its sixth annual Global sustainability report on Wednesday 10 July, which revealed

had achieved its goal to become a 100% renewably powered company seven years ahead of schedule.

This means all of the electricity the company uses to power its operations, including its datacentres, was balanced out by investments in 513 renewable energy projects around the world during 2023.

“Collectively, our portfolio represents 28 gigawatts (GW) of renewable energy capacity, an increase from 20GW in 2022, the company said,

. “This portfolio [of renewable energy projects] provides carbon-free electricity to the grids in communities where we operate. With this scale, we have been named the world’s largest purchaser of renewable energy for the fourth year in a row.”

directly attribute the 11% year-on-year decrease in its Scope 2 emissions it achieved in 2023 to its investments in renewable power sources. “This decrease resulted from our increased use of electricity from renewable sources, such as wind and onsite solar, as well as from purchasing additional environmental attributes (such as renewable energy credits) to signal our support for renewable energy in the grids where we operate, in line with the expected generation of the projects we have contracted,” it said.

However, the company’s reliance on investing in renewable projects to balance out the use of non-renewable energy sources elsewhere in its business has seen

going public with its pledge to become a net-zero entity by 2040, and has since staged walkouts to induce the company to change the way it works and ensure its operations do not risk contributing towards climate change.

‘Creative accounting’

According to the group,

’s renewable energy milestone has been achieved using “creative accounting” and, despite what the company claims, the way it runs its operations is unsustainable.

“A company that runs millions of diesel truck trips through working class neighbourhoods and playgrounds and has datacentres using more energy than entire cities should not claim it is doing a great job by achieving a 100% renewable goal (using creative accounting),” said a representative from the group, in a statement to Computer Weekly.

“The [AECJ] paper you’re referring [to] has incorrect findings and assumptions, likely because, as its authors admit, it’s based on data and opinion from outside the company.”

The last bit of that statement is a description the members of AECJ would take issue with, given the group’s statement goes on to emphasise that its members’ opinions are based on having inside knowledge of the company’s inner workings.

AWS under scrutiny

, he said the fact the report does not provide a separate breakdown of the greenhouse gas emissions generated solely by its public cloud arm,

Web Services (AWS), is a concern.

The company has produced a summary document of AWS’s contributions to the company’s overall environmental footprint, but it lacks specific details on the Scope 1, Scope 2 and Scope 3 emissions generated solely by AWS.

And for that reason,

’s environmental report (and the accompanying summary of the work underway at AWS to reduce its carbon emissions) is of limited value to IT buyers, said Butcher.

Particularly as the publication of

“AWS numbers are still hidden amidst the corporate

totals,” he said. “These numbers cannot and should not – in my honest opinion – be used to compare against their competitors. They are not granular, nor meaningful.”

Emissions decrease

What the

2023 environmental report does state, however, is that the company’s total carbon emissions decreased by 3% compared with 2022, with the firm reporting an 11% year-on-year reduction in Scope 2 emissions and a further 5% fall in Scope 3 emissions, too. Its Scope 1 emissions, however, increased by 7% over the same *******.

Even so, Butcher’s view is that

’s sole reliance on “market-based methods” when calculating its Scope 2 and Scope 3 GHG emissions does not give an accurate account of the company’s total environmental footprint anyway.

“[Its] Scope 2 [emissions are] market-based and not location-based – and organisations should do both. [If they included] location-based data [its emissions] would be massively, massively higher,” he said.

The company’s Scope 3 emissions are also “spend-based estimates” which, according to Butcher, means there is no way of knowing if this data is correct. “This approach means the data cannot be really used to drive decisions,” he added.

And that’s not the only issue AWS customers have with the company and its approach to Scope 3 emissions.

As previously reported by Computer Weekly, AWS has come in for criticism in the past for the fact that the tool it built and made available to its customers so they could track the carbon emissions generated by their use of its cloud services does not include Scope 3 contributions.

The company previously advised Computer Weekly that this functionality would be added to its Customer Carbon Footprint Tracking Tool in early 2024, but – at the time of writing – no updates to the tool of this nature have been forthcoming.

It is understood the company is in the throes of carrying out the necessary life-cycle assessments required to generate Scope 3 emissions data for incorporation into the Customer Carbon Footprint Tool. But there is no indication as of yet when that work will be complete.

data being made available to AWS customers.

“The AWS Customer Carbon Footprint Tool was embarrassing when it was initially released, and it has made no progress in the years since then,” he wrote. “They’ve told me they have a team working on it, but until something is released, this is a huge gap.

“The [

Computer Weekly asked

for clarity on when the AWS Customer Carbon Footprint Tool might be updated, but the company did not directly answer the question.
