A carbon footprint is defined as:
The total amount of greenhouse gases, and specifically carbon dioxide, produced to directly and indirectly support human activities, usually expressed in (a) , during the period of a year, and they can be associated with an individual, an organization, a product or an event, among others.
Which of these are some of the primary greenhouse gases in Earth's atmosphere? (choose as many answers as appropriate)
CO2
CH4
N2O
H2O
Human activities since the beginning of the Industrial Revolution (around 1750) have produced a 45% increase in the atmospheric concentration of carbon dioxide, from 280 ppm in 1750 to (a) ppm in 2023.
This is a graph of the accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.

This Review has assessed a wide range of evidence on the impacts of climate change and on the economic costs, and has used a number of different techniques to assess costs and risks.
(a)
Humanity is emitting greenhouse gases, changing the climate, and threatening ourselves and other species and future generations in many very dangerous ways.
We use two terms to reflect two different ways of responding to this challenge. Both of which are important.
One term, _______, means to reduce what we're doing that's causing the climate to change. The other term that we use is _______to reduce our vulnerability to the harmful effects of climate change .

This system is a way to compensate for businesses` emissions by funding an equivalent carbon dioxide saving elsewhere. It is used to balance out these emissions by helping to pay for emission savings in other parts of the world.

(a) energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes.
This is organic material such as wood waste, agricultural crops or wastes, and municipal wastes, and it is a renewable source of energy.
Biophilia
Biomass
Biomimicry
Biotin
This renewable energy is generated by converting kinetic energy from water into electrical energy. To harness this power, enormous infrastructures are built to extract maximum power from this renewable emission-free, local resource.

The first global conference on the environment was an international conference convened under United Nations auspices held in 1972. It was the UN's first major conference on international environmental issues, and marked a turning point in the development of international environmental politics. One of the major results of this conference was the creation of the UNEP. Which Conference are we talking about?
Montreal protocol
Rio Earth summit
Kyoto protocol
Stockholm conference
This is the landmark multilateral environmental agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone depleting substances (ODS). When released to the atmosphere, those chemicals damage the stratospheric ozone layer, Earth’s protective shield that protects humans and the environment from harmful levels of ultraviolet radiation from the sun. Adopted in 1987 by all UN Member States.
Kyoto protocol
Montreal protocol
Berlin mandate
Rio Earth summit
This international agreement, which took place in 1992, was the largest environmental conference ever held, attracting over 30,000 people including more than 100 heads of state.
The objectives of the conference were to build upon the hopes and achievements of the Brundtland Report, in order to respond to pressing global environmental problems and to agree major treaties on biodiversity, climate change and forest management. Agenda 21: came from this convention. A non-binding UN resolution that suggests ways for governments and NGOs to promote sustainable development (combat poverty and pollution and conserve natural resources)
Rio Earth Summit
Paris agreement
Kyoto protocol
Berlin mandate
The three treaties from the Rio Earth summit are (write down the acronyms):
1. ___,
2. ___,
3. ___
(a)
1997. This is an international agreement linked to the United Nations Framework Convention on Climate Change (UNFCCC), which commits its Parties by setting internationally mandatory emission reduction targets. It consists in two commitment periods.
Montreal protocol
Kyoto protocol
Rio Earth summit
Paris agreement
Kyoto protocol: During the second commitment period – (2013-2020), Parties committed to reduce GHG emissions by at least (a) % below 1990 levels in the eight-year period from 2013 to 2020.
International agreements: Identify COP21, which took place in 2015. For the first time, this agreement included a specific target for limiting global warming to well below 2°C above the pre-industrial levels of 1750. The ratified countries set their own reduction targets, whereby a review and strengthening of the climate protection efforts was to take place every 5 years. In October 2016, the required number of at least 55 ratified countries, which are responsible for at least 55 % of the global greenhouse gas emissions, was reached, which meant the agreement could enter into force.

Plastics: A number__ inside the recyclability triangle indicates the plastic is polyethylene terephthalate, which is shortened to PET or PETE. This symbol is normally found on bottles for soft drinks and water; salad dressing, peanut butter, and vegetable oil containers; and mouthwash bottles.
PET bottles can be recycled into new containers, pallet straps, paneling, carpet and clothing fibers, and fiberfill for soft furnishings and sleeping bags.

In this system, the consumer products are recycled and used to create a new or different type of product instead of being stored as garbage.
The original raw materials are transformed into useable products repeatedly, which reduces the need to gather new raw materials and reduces the amount of waste that must be disposed of in landfills.

These type of non-renewable resources resulted from the conversion of the energy of the sun into chemical energy, in the form of plant and animal tissues over many millions of years.

This is the European Union's Earth observation programme, looking at our planet and its environment to benefit all European citizens. It offers information services that draw from satellite Earth Observation and in-situ (non-space) data. It consists in 6 satelites or sentinels.
