RESTCo - Making Waves at CIRSIP 2019 (Remote Energy Security Technologies Collaborative [RESTCo])
Remember, methane has 56 times the warming potential of CO2 (20 year GWP), so it needs to be a focus
for work on mitigating climate change. (You will see lower numbers for CO2 GWP in mainstream media
reports - based on the 100 year GWP value. However, we don't have a century left to act. We have
months, and about a decade to have the turnaround well under way.
From the report:
"According to Royer et al., the highest gas-producing plastic (LPDE in powder format) produced
methane at a rate of 55 nmol per gram per day. Using the estimated 236,000 Mt of standing stock of
sea surface microplastic pollution from the 2015 van Sebille model, there is an annual emissions
rate of 4.74 x 1015 nmol per year. This totals an annual methane production of 76 Mt from the
standing stock of plastic at the sea surface. Applying the 100-year global warming potential of
methane yields annual greenhouse gas emissions of 2,129 Mt CO2e.
"Royer et al. also determined a rate for ethylene in LDPE powder form. Doing the same calculation
for ethylene equates to 51 Mt of annual ethylene production."
For more on plastic pollution, see the RESTCo pages.
In Canada, 60% of all industrial emissions come from the oil and gas sector. Planting trees and allowing them to
grow to maturity is a superb carbon sink. Unfortunately, Canada's forests are now a net carbon emitter due to
forest fires and our unwillingness to deal with the issue pre-emptively. And, our most populous province just
killed its program for planting trees as a carbon sink to pay for corporate tax cuts.
Hmmmm, biodigesters? Landfill methane gas collection?

I present a lot of information in this blog and on this website. If you need some help sorting through the
noise level and getting a forward-looking, proactive approach to climate change for your business, I can do
