Lesson 1
The Planetary boundary framework: what it is? Give examples of some
planetary boundaries (with explanation, and their status)
A framework that defines the limits within which human activities can affect the
environment without causing long-term harm. Crossing these limits may disrupt the
Earth's ability to self-regulate.
It identifies 9 key Earth system processes that are essential for the planet's stability.
If we cross these boundaries, the risk of severe and irreversible environmental damage
increases.
1. Climate Change
Human activities release too much GHG, especially CO₂. The GHGs trap heat and
this warms the planet and disrupts weather and ecosystems.
→ Boundary is crossed.
2. Biodiversity Loss (Biosphere Integrity)
Too many species are disappearing due to deforestation, pollution, and climate
change. This weakens ecosystems and natural balance.
→ Boundary is crossed.
3. Biogeochemical Flows
The disruption of the natural nutrient cycles of key elements like nitrogen, and
phosphorus through the environment and organisms, which are crucial for
supporting life and maintaining ecosystems. Both the global phosphorus flow into
the ocean and the industrial fixation of nitrogen (extracting nitrogen from the
atmosphere), are disrupting the corresponding nutrient cycles beyond the safe level.
This causes issues such as dead zones in water bodies (eutrophication)
→ Boundary is crossed.
4. Freshwater change
Human impact on freshwater sources such as rivers, lakes, and groundwater for
agriculture and industry disrupts natural water cycles and leads to water scarcity.
Human-induced disturbances of both blue water (e.g. rivers and lakes) and green
water (i.e. soil moisture) have exceeded the safe level.
→ Boundary is crossed.
5. Novel Entities
Introduction of synthetic chemicals and substances like persistent pollutants
(POP), radioactive materials, microplastics, chemicals, and genetically modified
, organisms (GMO) harms the environment and humans
→ Boundary is crossed.
6. Land-System Change
Large-scale deforestation and land conversion reduce the Earth's capacity to store
carbon and support biodiversity.
a. Conversion of natural ecosystems (e.g. forests) to urban/agricultural use.
→ Boundary is crossed.
7. Ocean Acidification
Oceans absorb CO₂, which lowers pH and harms marine ecosystems like corals and
shellfish overall reducing the ocean's efficiency in acting as a carbon sink.
→ Close to being crossed. (crossed according to some recent reports)
8. Atmospheric Aerosol Loading
The rise in airborne particles from human activities or natural sources influences the
climate by altering temperature and precipitation patterns.
Air + Small Particulate Matter = Aerosol.
→ Still within safe space.
9. Stratospheric Ozone Depletion
The ozone layer protects the earth and humans from harmful UV radiation and
certain chemicals cause the ozone layer to disappear, which leads to more UV
radiation reaching the Earth but is currently under control.
→ Within safe space.
Explain what the new EU Circular economy action plan (CEAP 2.0), including
its main objectives
The new EU Circular Economy Action Plan (CEAP 2.0) was adopted in 2020 as one of
the main building blocks of the European Green Deal.
It aims to make the EU economy more sustainable by addressing the entire life cycle of
products, from design and production to consumption, repair, reuse, and recycling.
Main objectives of CEAP 2.0:
1. Make sustainable products the norm in the EU
2. Empower consumers and public buyers (to make better decisions)
3. Focus on the sectors that use most resources and where the potential for
circularity is high such as: electronics and ICT, batteries and vehicles, packaging,
plastics, textiles, construction and buildings, food, water and nutrients
, 4. Ensure less waste is generated
5. Promote circular economy work for people, regions and cities (inclusivity)
6. Lead global efforts on circular economy
Explain what the Sustainable Products Initiative (SPI) is
SPI is a policy initiative launched under CEAP 2.0. Its aim is to make all products on the
EU market more durable, repairable, reusable, recyclable, and energy-efficient,
throughout their entire lifecycle
It set the initiative for the first objective of the CEAP 2.0 (make sustainable products the
norm in the EU)
It shifts sustainability requirements beyond just energy-using products to nearly all types of
goods. The SPI sets the direction for what sustainable products should look like and
introduces new concepts like the Digital Product Passport to increase transparency and
traceability.
Explain what the EU Ecodesign for Sustainable Products Regulation is
(including its aim)
ESPR is the legal tool that puts the SPI into action. It replaces the old Ecodesign Directive
and extends its scope from energy-related products to almost all physical goods (except
food, feed, and medicine).
It allows the EU to set mandatory design rules for products—known as ecodesign
requirements—which can cover:
● Durability, reparability, reusability
● Recyclability and recycled content
● Energy and resource efficiency
● Restrictions on harmful substances
● Clear information on environmental footprint
ESPR ensures that sustainable design becomes a legal obligation, not just a guideline.
part of the EU approach to more environmentally sustainable and circular products.
part of a package of measures to :
● Achieve the aims of the 2020 Circular Economy Action Plan
● fostering the transition to a circular, sustainable, and competitive economy.
● It will also play a central role in developing a strong, well-functioning single market
for sustainable products in the EU.
, Explain what a digital product passport is, including which information it
should contain
A digital product passport is an electronic record that provides detailed information about a
product throughout its lifecycle. It is designed to improve transparency, traceability, and
sustainability in the EU market.
accessible electronically, making it easier for consumers, manufacturers, and authorities to
make more informed decisions related to sustainability, circularity and regulatory
compliance.
It can include
● Product’s technical performance
● Materials and their origins
● Repair activities
● Recycling capabilities
● Lifecycle environmental impact
Explain what the Stockholm convention is and how it works
A UN global treaty that aims to protect human health and the environment from the harmful
effects of persistent organic pollutants (POPs). These are toxic chemicals that remain in
the environment for a long time, accumulate in living organisms, and can travel long
distances and cross international borders, which makes them require an international
regulation system. Aarhus convention and Stockholm convention come into force here.
Under the Stockholm Convention, which currently manages 29 POPs, parties agreed to
adopt a range of control measures to reduce and, where feasible, eliminate the release of
POPs.
The convention works by requiring countries to take measures to eliminate or restrict the
production and use of intentionally produced POPs, with limited exemptions.
● Parties shall prohibit or restrict their production and use, subject to certain
exemptions such as the continued use of DDT.
● Requires parties to restrict trade in such substances.
● For unintentionally produced POPs, the Stockholm Convention requires countries
to develop national action plans to address releases and to apply “Best Available
Techniques” to control them.
● Aims to ensure the sound management of stockpiles and wastes that contain POPs
