Earth Overshoot Day 2021

Earth Overshoot Day 2021 lands on July 29. The news was announced on 04 June by Councillor Susan Aitken, the Leader of Glasgow City Council, on behalf of Global Footprint Network and the Scottish Environment Protection Agency (SEPA).
‘With almost half a year remaining, we will already have used up our quota of the Earth’s biological resources for 2021 by July 29th. If we need reminding that we’re in the grip of a climate and ecological emergency, Earth Overshoot Day is it’, she said.

Deforestation and lockdowns

2021’s Earth Overshoot Day is almost as early as it was in 2019, after being momentarily pushed back in 2020 by the coronavirus pandemic-induced lockdowns.

Notable drivers are the 6.6% carbon footprint increase over last year, as well as the 0.5% decrease in global forest biocapacity due in large part to the spike in Amazon deforestation.

In Brazil alone, 1.1 million hectares were lost in 2020 and estimates for 2021 indicate up to 43% year-over-year increase in deforestation.

‘As the UN Decade of Ecosystems Restoration is launched on World Environment Day, June 05, this data makes abundantly clear that recovery plans in the post-Covid 19 era can only be successful in the long term if they embrace regeneration and ecological resource-efficiency.’

Humans use 1.7 Earths

Each year, Earth Overshoot Day marks the date when humanity has used all the biological resources that Earth regenerates during the entire year.

Humanity currently uses 74% more than what the planet’s ecosystems can regenerate—or ‘1.7 Earths.’

From Earth Overshoot Day until the end of the year, humanity operates on ecological deficit spending.

This spending is currently some of the largest since the world entered into ecological overshoot in the early 1970s, according to the National Footprint & Biocapacity Accounts (NFA) based on UN datasets.

Coal use expected to jump

In 2021 the carbon footprint of transportation remains lower than pre-pandemic levels. CO2 emissions from domestic air travel and road transport are set to remain 5% below 2019 levels, while international aviation is expected to register 33% below, according the International Energy Agency (IEA).

Global energy-related CO2 emissions, on the other hand, are projected to rebound and grow by 4.8% from last year as the economic recovery ignites demand for fossil fuels.

In particular, global coal use is anticipated to jump in 2021 and is estimated to contribute 40% of the total carbon footprint this year.

‘Let Earth Overshoot Day be our call to arms. In November the eyes of the world will be on Glasgow, host of COP26, the climate summit that needs to make the decisions that will deliver our planet on a safer and more sustainable future.

‘We’ve got the opportunity here in Glasgow to show the world what we’re doing, coalescing together as a city to show real change, to respond to the climate and ecological emergency. Let’s put our planet first and let’s #MoveTheDate together.’

Leader of Glasgow City Council

A net-zero revolution

Last year, as the pandemic hit around the world, governments demonstrated they can act swiftly, both in terms of regulations and spending, when they put human lives above all else.

The perfect storm that is brewing, as climate change impacts and biological resource security converge, requires the same level—or higher—of alertness and swift action from decision makers.

‘In November, as a weary world turns its attention to Scotland and COP26, together we can choose one-planet prosperity over one-planet misery. We can and must build from the pandemic – our global ability to plan, to protect and move at pace. Scottish innovation helped lead the Industrial Revolution; in 2021, the Glasgow summit and the future we choose as each community, city, company or country, offers real hope for a new net-zero revolution.’


An opportunity for cities

Through their infrastructure and regulatory powers, cities have significant opportunities to shape their resource efficiency and, with it, their future.

Given their risk exposure, aligning their development plans with what resiliency requires in a world shaped by climate change and biological resource constraints, has become cities’ utmost priority regardless of international agreements.

‘Cities are ideal living laboratories for social and environmental innovation, offering significant learning to create real-world solutions and transformation. And universities have an obligation to act in partnership with their host cities to accelerate progress toward a just and sustainable future.

‘We are working with a people- and place-based approach to deliver positive change for a climate-resilient city whose legacy lasts beyond COP26.’

Director of the University of Glasgow’s Centre for Sustainable Solutions
