Silvopasture – continued meat production that produces less emissions
Material Circularity
Billion Tonne Solutions
Nine Planetary Boundaries
Donut Economic Model
Life Cycle Assessment – a systematic process that evaluates the environmental impact of a product, service, or system throughout its entire life cycle. (energy usage → CO2E to calculate)
Product Environmental Footprint
The five tonne lifestyle
The social and environmental impact assessment (SIA and EIA) model is a methodological tool that helps predict the potential consequences of a project or program on the environment and community. – important to consider when
Gold Soil Standard – Catering
BREEAM Certification – Energy consumption within buildings
Material Circularity
Reporting of carbon – Scope 1, 2, and 3
Offsetting – buying into wind farms, solar farms, etc. to offset the amount of energy used
Notes:
Perceptions about Climate Crisis, Carbon Emergency, Climate Change – especially in communications or marketing
Nine Planetary Boundaries
Stratospheric Ozone Depletion – CFCs
Atmospheric Aerosol Loading
Ocean Acidification
Biogeochemical Flows –
Green Water – water in the soil for plants to use
Carbon Sink
Radiative Forcing
Novel Entities – “things created and introduced into the environment by human beings that could have positive or negative disruptive effects on the earth system” – Plastic, etc.
Donut Economic Model
Greenhouse Earth
Troposphere; tropo – to twist, to change; a layer that changes constantly
Greenhouse Gases – 80% is CO2 | Methane, N2O, F-Gases, Ozone, Water Vapour
GWP – Global Warming Potential – how hot can it get? In comparison to CO2
CO2E – E-Equivalent – to have considered other Greenhouses Gasses in the emissions
CO2 E (Gt) – Gt – billion tonnes & gigatonnes
Methane emission sources – landfills, rice production (already produced in a way that is less methanogenic), wetland degradation, enteric fermentation – waste from cows and sheep, fugitive emissions – used by oil and gas industries for technical faults in oil and gas leaks,
methane is stored in the soil, it bubbles up naturally, wetlands
N2O – fertilizer use, fossil fuel combustion
F-Gas – refrigerators, air conditions
5000kg per year, so carbon budget per day =5000/365
Sending emails? – carbon emissions?
