When we refer to sustainability in ecology, we describe how biological systems “hold” themselves, serve us as resources, and are produced over time. According to Junk Bunk Ltd, a waste management company in London, the generation of large amounts of non-recyclable waste has an even greater impact on environmental sustainability than in previous years.
The 1987 United Nations Brundtland Commission defined sustainability as “meeting the needs of the present without compromising the ability of future generations to meet their own needs.”
Types of durability
Sustainability requires a common ideal and that is why it is a socio-economic process.
We can say that there are several types of sustainability.
The redistribution of political and economic power ensures that there are stable rules in the country, that we have a secure government and establish a legal framework that guarantees respect for people and the environment.
It fosters solidarity relations between communities and regions, thus improving the quality of life and reducing dependence on communities, thus generating democratic structures.
When we talk about this sustainability, we refer to the ability to generate wealth in equal amounts and appropriate for different social spheres so that populations are fully capable and solvers of their financial problems, which in themselves can increase production and strengthen consumption in monetary production sectors.
Therefore, if sustainability is a balance, this kind of sustainability is a balance between nature and man, a balance that seeks to satisfy current needs without sacrificing future generations.
This type of consistency is the most important and the object of “analysis” in this article.
It refers to nothing more or less than the ability to preserve biological aspects in its productivity and diversity over time. In this way, the conservation of natural resources is achieved.
This sustainability encourages conscious responsibilities for the environment and it makes human development grow by caring for and respecting the environment in which one lives.
Measuring environmental sustainability
Sustainability measures are environmental or other types, they are quantitative measures in the developmental stages able to formulate environmental management methods.
The 3 best measures today are the Environmental Sustainability Index, the Environmental Performance Index and the triple score.
This is a recent index and is a Global Leaders Initiative for Tomorrow environmental task force of the World Economic Forum.
The Environmental Sustainability Index or Environmental Sustainability Index, for ESI, is a hierarchically structured indexed index, which includes 67 weighted Variables of equal weight in total (structured in 5 components, by other consisting of 22 factors).
In this way, ESI combines 22 environmental indicators ranging from air quality, and waste reduction to common international protection.
Grades obtained from each country are divided into 67 more specific subjects, such as measurement of sulfur dioxide in urban air and deaths associated with poor sanitation.
ESI measures five focal points:
- The state of the environmental systems of each country.
- The success was achieved in the task of reducing major problems in environmental systems.
- Progress in protecting citizens from possible environmental damage.
- The social and institutional capacity that each nation has to take action on the environment.
- The level of administration that each country has.
This is an index that, as a mega number aggregation, aims to be “weighted” with GDP and the International Competitiveness Index (ICI), to supplement essential information, to better guide policy-making, policy-making and execution.
The range of environmental variables involved is extremely complete (pollutant concentrations and emissions, water quality and quantity, energy consumption and efficiency, vehicle-exclusive area, agrochemical use, population growth, corruption perception, environmental management, etc.). .) the authors themselves acknowledge that there are very interesting variables about which there is no information.
From the information they share, the first results of this index seem to be consistent with what can be observed in reality, the countries with the best ESI values are countries like Sweden, Canada, Denmark and New Zealand.
Environmental Performance Index
The Environmental Performance Index (EPI) is a method of numerically determining and classifying the environmental performance of a country’s policies.
The variables taken into account for calculating EPI are divided into 2 objectives: ecosystem vitality and environmental health.
Also, environmental health is divided into political categories which are:
- Effects of air quality on health.
- Basic sewers and drinking water.
- Environmental impact on health.
And the vitality of the environment is divided into 5 political categories also which are:
- Productive natural resources.
- Biodiversity and habitat.
- Water resources.
- Effects of air pollution on ecosystems.
- Climate change.
The triple line or triple end is nothing more than a term associated with sustainable business, referring to the performance caused by a company expressed in three dimensions: social, economic and environmental.
Evidence of performance about the triple score is manifested in corporate sustainability or social responsibility ratios.
In addition, in an organisation with good performance in terms of accounting, a triple line would result in maximising its economic benefit and environmental responsibility, as well as minimising or eliminating its negative externalities, emphasising the social responsibility of the organisation to stakeholders, and not just to shareholders.
