TORONTO, Aug. 1, 2023 – The Earth’s account is once again overdrawn, but rather than money it is natural resources that humanity has used up. Tomorrow is the day that becomes official – – when the Earth is no longer able to renew what humans have used this year.

“During the pandemic when we weren’t using quite as many resources, we actually did better, but now were back to where we started. Seven months into the year and the account is empty,” says , director of the in 91��ɫ’s Faculty of Environmental and Urban Change.

Miller leads a team of researchers and graduate students to produce the  for the , a Canadian not-for-profit organization.

Since 1970, humanity’s Ecological Footprint has overshot the capacity of nature to sustain it. 

Humanity's goal of getting to "net zero emission" will require ending Earth overshoot, he says.

Miller is available to speak with media about Earth Overshoot Day and what it means for Ontario and the rest of Canada. He can also speak about the detailed calculations and what the results mean. He is a member of Ontario’s Biodiversity Council and is the former head economist at the Ministry of Natural Resources.

TORONTO, Aug. 20, 2020 – By Saturday, humanity will have overdrawn its ecological account for the year. Known as , it’s the day when humans will have used as much from the Earth as the planet can renew in a year.  91��ɫ produces the data that informs this calculation.

The good news is that Earth Overshoot Day this year – August 22 – arrives 21 days later than in 2019.  Coronavirus-induced lockdowns around the world have reduced the burning of fossil fuels and reduced wood harvests. Even so, the world will demand more from nature than can be renewed this year.

91��ɫ has partnered with the to calculate the Ecological Footprint and Biocapacity of every nation on the planet.  This data is needed to determine Earth Overshoot Day.

“At a time when the COVID-19 pandemic has shown us the true scale of our global interconnectedness, we have an opportunity to leverage partnership and collaboration to overcome complex global challenges like inequality, COVID-19, and of course, climate change,” says President & Vice-Chancellor Rhonda Lenton. “91��ɫ is proud to provide leadership through an international research collaboration like the Ecological Footprint initiative that helps countries determine whether they are on track to meeting the Sustainable Development Goals, and gives us the data to calculate Earth Overshoot Day.”

Eric Miller leads a team of researchers and graduate students in 91��ɫ’s Faculty of Environmental Studies to produce the for the , a Canadian not-for-profit organization.

Miller and his team measure the carbon footprint, the amount of built-up land or urban sprawl, how much forest is used for timber and paper, how much cropland and pasture is used to produce food and the amount of seafood fished every year.  These all add up to humanity’s Ecological Footprint.

Since 1970, humanity’s Ecological Footprint has overshot the capacity of nature to sustain it.  The resulting ecological debt has been an in the atmosphere and .

“As we emerge from the pandemic, we must rebuild our economies for well-being and sustainability.  We need regenerative economies that use natural resources at rates that can be sustained,” says Miller.

91��ɫ’s measurement of the Ecological Footprint helps to inform individuals, communities, and governments to make better decisions on how to better manage resources, reduce economic risk and improve well-being.

Researchers and students, who work on the accounts at 91��ɫ, are available to discuss the Ecological Footprint or Earth Overshoot Day.
