Chapter 3 - Environmental Factors Flashcards
(104 cards)
Climate Change
(Bonus: 2 Examples)
Changes in the earth’s systems which determine climate, e.g.
* increase in heat-trapping gases in the atmosphere
* change in reflectivity of earth’s surface
Climate Change Mitigation
A set of actions that reduce the earth’s added warming
Examples and Challenges of Climate Change Mitigation Actions
(4 Examples)
- avoid dangerous interference with climate system
- stabilize GHG levels to allow reduction in atmosphere and therefore lower earth’s temperature
- ensure food production is not threatened
- ensure economic development to proceed in sustainable manner
Climate Change Adaption
A set of actions for humans to adapt to warming world, rising seas, droughts, rainfall and storms
Examples of Climate Change Adaption Actions
(7 Examples)
- protecting coastlines and adopting to sea-level rise
- building flood defences
- managing land use and forestry practices
- planning more efficiently for scarce water resources
- developing drought-resilient crops
- protecting energy and public infrastructure
- developing clean cooling systems
Resiliance Measures
Adaption actions that function even though climate is changing
Issues in the Quantification of Losses from Climate Change in the Future
(3 Issues)
- due to discounting (inflation), cash flows in the future have little present value
- Dismal Theorem: no matter how small the probability, if the uncertainty of climate change is large (e.g. civilization collapse) the expected value becomes negative infinity
- negative impacts of climate damages ramp up only gradually, without tipping points, in the estimations
What are the Climate Change estimates of the Intergovernmental Panel on Climate Change (IPCC)?
(3 Estimates)
- human activities caused approx. 1.1°C of global warming (above pre-industrial levels)
- likely to reach 1.5°C by 2040, even under the very low emission scenario
- difference between 1.5°C and 2.0°C by 2100: 400 million fewer people exposed to extreme heatwaves and 10 million fewer people exposed to rising sea levels; arctic and warm water coral reefs mostly disappear at 2.0°C (above pre-industrial levels)
Pressures and Measures on Water as Natural Resource
(3 Examples)
70% of the planet is water, but only 2.5% of it is Fresh Water
* water demand set to increase in all sectors (e.g. agricultural, industrial, energy generation, mineral extraction and cooling)
* currently 2 billion people experience high water stress; 4 billion people experience water scarcity at least one month of the year
* UN’s Sustainability Development Goal 6 (SDG 6) “ensure availability and sustainable management of water and sanitation to all” by 2030
Pressures on Biodiversity as Natural Resource
(5 Examples)
- around 1 million animal and plant species are now threatened with extintion
- humans impacted over 75% of earths land and 66% of oceans
- WWF: world wildlife population dropped 68% since 1970
- 70% of cancer drugs are organic or from organic substances
- biodiversity ecosystem services: food, clean water, genetic resources, flood protection, nutrient cycling, climate regulation, pollination
Pressures on Land Use and Forestry as Natural Resource
(4 Examples)
- impact on natural resources, e.g. water, soil, nutrients, plants, animals
- 30% of worlds land are forests
- forests are vital to convert CO₂ into Oxygen, the older the tree the better the conversion
- from 2001 to 2019: 9.7% decrease in tree cover
Pressures on Marine as Natural Resource
(3 Examples)
- ocean is planets largest CO₂ reservoir (43x more than atmosphere)
- provides: food, shipping ways, mineral mining and oil
- over-fishing is a concern: 33% fish harvested at unsustainable levels; 60% harvested at maximum sustainable levels; 7% harvested below sustainable levels
Effects of Air Pollution
(7 Effects)
- adversely affects environment
- negative impact on human health
- destroys ecosystems
- impacts biodiversity
- reduces crop harvest due to soil acidification
- over 7 million deaths globally each year
- 99% of population living in places where air quality levels were not met
Effects of Water Pollution
(2 Effects)
- contaminents (e.g. chemical or harmful microorganisms, sewage and industrial waste) are introduced into the water
- fines for water pollution are increasing worldwide
Issues with Waste and Waste Management
(3 Issues)
- landfill space limited and charges rising
- recycling practices very uneven between countries
- concern regarding single-use plastics and the damages it does to the ocean
Plastic Strategies for Waste and Waste Management
(2 Strategies)
- UN Environment Assembly: commit to develop international legally binding agreement to end plastic pollution
- European Strategy for Plastics in a Circular Economy: all plastic packaging must be reuseable or recycleable by 2030
Principles of a Circular Economy
(3 Principles)
- design out waste and pollution
- keep product and materials in use
- regenerate natural systems
Circular Economy in 5 key areas can eliminate emissions by half:
(cement, aluminium, steel, plastics, food)
Physical Risks of Climate Change
(2 Risks)
- more frequent or severe weather events, e.g. flooding, droughts, storms
- Insurer are double exposed as events affect real estate in their portfolio and liabilities
Transition Risk of Climate Change for Entities
(3 Risks)
- Policy Risk: e.g. increased emission regulation and environmental standards
- Legal Risk: e.g. lawsuits claiming from entities believed to be liable for the contribution to climate change
- Technology Risk: e.g. low-carbon innovations disrupting established industries
Impacts of an Organisation on Biodiversity
(5 Impacts)
Direct Impact:
* degraded land is converted for production activities
* surface water as supply to fields
Indirect Impact:
* from supply chains (e.g. import fruit and vegetables, produce cotton shirts, sell construction materials, publish books)
Negative Impact:
* degrading quality or quantity of biodiversity
Positive Impact:
* creating a net contribution to quality and quantity of biodiversity
Indirect Impact is difficult to predict and manage, but can be major
Sectors with highest potential Negative Affect to Biodiversity
(6 Sectors)
- agriculture, aquaculture, fisheries, food production
- fast moving consumer goods
- forestry (wood products, paper, fiber, energy)
- pharmaceutical (in some cases)
- tourism and hospitality (in some cases)
- utilities (incl. hydropower or open-cycle power plants with significant thermal discharges)
Potential Environmental Impacts from direct Operations
(8 Impacts)
- Toxic Waste
- Water Pollution
- Loss of Biodiversity
- Deforestation
- Energy Use
- Long-term Damage to Ecosystem
- Water Scarcity
- Hazardous Air Emissions and high GHG Emissions
Supply Chain Sustainability
(2 Points)
To manage ESG impacts and practices for raw materials and components that come from outside the factory gates.
Looking at the broader life cycle of goods and services, particularly with regard to the sourcing of raw materials and components.
Challenges of addressing Climate issues in the Supply Chain
(for 2 Industries)
Industry:
* growing demand for materials with slow adoption of renewable energy and process improvements
Food System:
* require change in food consumption behaviour and food production behaviour, as well as decarbonization of supply chains
