COP15 Biodiversity Agreement: By 2030, Achieving 4 overarching global goals with 23 targets?

After two weeks, the UN Biodiversity Conference ended on 19 December. The so-called COP15 (15th Conference of the Parties to the UN Convention on Biological Diversity), held under the auspices of the United Nations (UNEP – UN Environmental Program) and chaired by China and hosted by Canada, adopted the “Kunming-Montreal Global Biodiversity Framework” (GBF – “Global Nature Agreement”), which contains four goals and 23 targets to be achieved by 2030.

Almost 200 countries were involved in the negotiations. The core of the joint final declaration is formed by the 23 nature conservation goals the global community wants to implement by 2030 to halt the dramatic loss of species and ecosystems. In addition to the financing of the measures, the role of indigenous peoples has also been highlighted: The steps should take into account the rights, traditions and knowledge of these peoples.

The agreement was celebrated as a success, but it is also criticised for being too sketchy and too diffident. The agreement has no legal effect, and it is now up to the participating countries to push for its implementation with appropriate means.

Here is a selection of the agreed targets (the complete declaration can be found here) wich shows that the desired success will only be possible with a joint approach by governments, industry and society.

  1. Effective conservation and management of at least 30% of the world’s lands, inland waters, coastal areas and oceans, with emphasis on areas of particular importance for biodiversity and ecosystem functioning and services. The GBF prioritizes ecologically-representative, well-connected and equitably-governed systems of protected areas and other effective area-based conservation, recognizing indigenous and traditional territories and practices. Currently 17% and 10% of the world’s terrestrial and marine areas respectively are under protection.
  2. Have restoration completed or underway on at least 30% of degraded terrestrial, inland waters, and coastal and marine ecosystems
  3. Reduce to near zero the loss of areas of high biodiversity importance,including ecosystems of high ecological integrity
  4. Cut global food waste in half and significantly reduce over consumption and waste generation
  5. Reduce by half both excess nutrients and the overall risk posed by pesticides and highly hazardous chemicals
  6. Progressively phase out or reform by 2030 subsidies that harm biodiversity by at least $500 billion per year, while scaling up positive incentives for biodiversity’s conservation and sustainable use
  7. Mobilize by 2030 at least $200 billion per year in domestic and international biodiversity-related funding from all sources – public and private
  8. Raise international financial flows from developed to developing countries,in particular least developed countries, small island developing States, and countries with economies in transition, to at least US$ 20 billion per year by 2025, and to at least US$ 30 billion per year by 2030
  9. Prevent the introduction of priority invasive alien species, and reduce by at least half the introduction and establishment of other known or potentially invasive alien species, and eradicate or control invasive alien species on islands and other priority sites
  10. Require large and transnational companies and financial institutions to monitor, assess, and transparently disclose their risks, dependencies and impacts on biodiversity through their operations, supply and value chains and portfolios.

Earth Overshoot Day

Globalisation and the industrial revolution have brought many positive changes for people. Still, dramatic consequences for our planet. Our environment and many ecosystems are heavily polluted by all kinds of contaminants. People are destroying the earth more and more every day, not thinking at all that this is our only earth.

Saving energy while protecting the climate?

The times when climate and environmental protection were always clearly on the “good” side are over. In the real-life implementation, alternative energies collide with nature conservation and species protection, as, e.g. in the case of off-shore wind farms. The discussion about “clean” nuclear energy is also difficult. In general, this means that one must take a closer look, weigh up the (long-term) impacts and evaluate the planned measures accordingly in a comprehensive manner. 

There are also side aspects to consider regarding air quality measurement. It is almost a paradox when air quality is measured by driving vehicles through the city. If the car has an electric drive, this has, at best, a NO2-reducing effect. The fine dust pollution from brake and tyre abrasion remains. And the environmental problems associated with the production of the necessary car batteries are widely known. 

A very topical issue at the moment is energy supply and energy consumption. There are also substantial differences in energy consumption of air quality measurements. The containers that operate the public measurements have an annual energy demand of 3,500 kWh to more than 11,000 kWh, depending on the equipment. This means that even the more economical measuring stations consume more than a typical 2-person household.  

With the Hawa Dawa measuring devices, the energy-consuming conditioning of the air before measuring is taken over by a calibration algorithm through the innovative use of artificial intelligence. This means that the annual energy consumption of our measuring devices is at the level of a standard household freezer – i.e. a fraction of the energy that has to be provided for a measuring station. 

Climate Justice – a topic no longer to be ignored

One of the most urgent aspects of climate action is environmental justice. At the ChangeNOW event in Paris, an entire session was dedicated to the fact that the people, who have the least impact on climate change, are the ones who are impacted the most – as the moderator, Lovelda Vincenzi, put it. The panel‘s discussion was around that the climate urgency is a global crisis, but its effects are not felt evenly around the world. The least polluting populations are the worst affected by climate change. International changemakers and political leaders must protect the rights of the most vulnerable and ensure the burdens of climate change are shared equally and fairly.

Tipping Points in Detail | Melting Ice (Ep 3/3)

We see pictures of emaciated polar bears every day and pity their fate – they are a living example of the sad reality in the Arctic. Yes, we pity them, but we often don’t realise that the melting of Arctic ice is just as damaging to us as it is to them.

Tipping Points in Detail | Ocean Currents (Ep 2/3)

Nature can be imagined like a human body. It is an arbitrarily complex system – everything is interconnected and in constant exchange. If one variable gets out of balance, the whole system can collapse. This is also the case with our oceans, the largest ecosystem covering over 70% of our planet.

Tipping Points in Detail | Amazon Rainforest (Ep 1/3)

We have already reported on tipping points and their properties in a previous blog post. What they are and what significance they already have for our environment. Since we would like to report in more detail about tipping points, we are dedicating a separate series to this topic – “Tipping Points in Detail”. In the first blog post of the 3-part series, we would like to bring you a little closer to the topic of the Amazon Rainforest. In the second part, we will talk about ocean currents and their importance for the animal and plant world and the effects on us humans. In the third and last part of our series, we will highlight the ice melt at the polar ice caps and some local glaciers.

Earth Day 2022 – get active now!

This year’s „Earth Day“, officially named „Mother Earth Day“, is the first one celebrated within the UN Decade on Ecosystem Restoration. Ecosystems support all life on Earth. The healthier our ecosystems are, the healthier the planet – and its people. Restoring our damaged ecosystems will help end poverty, combat climate change and prevent mass extinction. But we will only succeed if everyone plays a part.

We will share a couple of initiatives that try to activate all of us by using new approaches. Read more

Earth Day 2022 – A day for our Earth

For 52 years, Earth Day has been celebrated on 22 April in over 190 countries. The aim of the day is to raise people’s awareness of the importance of the Earth and the ecosystem and the consequences of environmental degradation in all its facets. People should rethink their own behaviour and question their everyday conduct.

Why ground-level ozone air pollution is a risk to food security

According to an IPCC scenario, the concentration of ground-level or tropospheric ozone (O3) may reach 70 ppb in 2050. Then, more than 30% of global cereal acreage could be exposed to significant ozone pollution, which in turn would lead to significantly lower crop yields.

Ground-level or tropospheric ozone (O3) is ingested by plants through their stomata (pores in the epidermis of plants) and has a growth-inhibiting effect: O3 leads to a reduced rate of photosynthesis, increased respiration and accelerated ageing of leaves. O3 also increases the plants’ susceptibility to diseases and other stress factors. O3 is also thought to alter the concentration of nitrogen, carbohydrates and phenols in the leaf and grain.
