Focus on Arts and Ecology

Purpose of the articles posted in the blog is to share knowledge and occurring events for ecology and biodiversity conservation and protection whereas biology will be human’s security. Remember, these are meant to be conversation starters, not mere broadcasts :) so I kindly request and would vastly prefer that you share your comments and thoughts on the blog-version of this Focus on Arts and Ecology (all its past + present + future).

5 key issues for COP23

Key issues @ COP23 

As climate negotiators meet to discuss the aims and implementation guidelines of the Paris Agreement, SEI researchers have put their heads together to identify some of the key issues for COP23. 
You can find out more about SEI’s participation in COP23 on our digital hub.

Regular updates from the conference will appear on SEI’s twitter feed @SEIclimate.

1.5°C and equity


What is at stake?
To reach the Paris Agreement’s goal of limiting warming to 1.5°C degrees, the global mitigation effort must be fairly distributed among countries. In other words, it must be equitable: countries with higher capacity and responsibility should contribute support to countries with lower capacity.

Who should do what?
Researchers from SEI, the Climate Equity Reference Project and EcoEquity have quantified each country’s range of ‘fair shares’ for mitigation compliant with a 1.5°C limit. They then looked at INDCs – and found that wealthier countries fell far short in their mitigation pledges, while poorer countries collective met their fair share.
The United States, for example, pledges at most only 24% of its ‘fair share’ contribution. For the European Union, that number is 23%. Industrialised countries – who have a higher capacity and higher responsibility – can’t reach their fair share with domestic emissions reductions. To meet their fair-share mitigation effort, they would have to cooperate to achieve mitigation opportunities in other countries.


Negative emissions


What are they?
The Paris Agreement calls for holding global average temperature increase to “well below” 2°C, and to “pursue efforts” to limit the temperature increase to 1.5°C. Given the slow pace of action to date, there is increasing interest in “negative emissions” – measures that remove carbon from the atmosphere – to help make up for lost time.

The most widely discussed options are large-scale afforestation, and bioenergy in combination with carbon capture and storage (BECCS). Landscape restoration – both restoration of closed canopy forests, and “mosaic” restoration of more intensively used landscapes – could also contribute to climate goals. Other ideas, such as direct air capture or ocean fertilization, are more speculative.

Why are negative emissions controversial?
An analysis by SEI has found three significant risks: (i) that negative emission options will not ultimately prove feasible; (ii) that their large-scale deployment involves unacceptable ecological and social impacts; and, (iii) that negative emissions activities prove less effective than hoped, either because they are subsequently reversed by human or natural forces, or because climate change impacts prove irreversible.

Aligning the NDCs and SDGs


What are they?
In September 2015, the UN General Assembly adopted the 17 Sustainable Development Goals. Three months later, the Paris Agreement was adopted, with NDCs as the core element for increasing climate ambition. The SDGs and NDCs are both implemented in a process by which countries set their own priorities and ambitions.
Under the Paris Agreement, more than 150 countries have committed to reducing greenhouse gas emissions in Nationally Determined Contributions (NDCs) that are ambitious and progress over time. But commitment is just the first step; preparing, financing and meeting NDC goals present unique challenges for every country.

Why does alignment matter now?
The NDCs are the most complete set of national pledges ever made to take concrete action under a multilateral agreement. But the aggregate ambition of all the plans needs to rise quickly because it is still indicating a 3°C degree average temperature rise – which can mean a devastating several degrees higher for the most vulnerable areas of the world. What’s more, the policies and interventions set out in NDCs need to be coordinated with the Sustainable Development Goals (SDGs).
Many countries need help to set and achieve goals through analysis, dialogues, capacity building and interactive tools. The NDC Explorer gives policy makers a cross-cutting, birds-eye view of NDCs. Accessible to all, this interactive tool puts NDCs in context, showing how countries are tackling high-emission sectors, adaptation and mitigation. SEI worked with the German Development Institute and the African Centre for Technology Studies to build the database and then analyse ambitions and priorities across countries. Researchers found trends that offer insights on the challenges and opportunities that lay ahead.
  • Many countries, for example, set targets for specific sources of renewable energy. But as few as 4 NDCs include agriculture as a priority area – despite its importance as a source of greenhouse gas emissions.
  • Poorer countries tend to focus more strongly on adaptation. Many developing countries make the implementation of their mitigation target partly or fully conditional upon receiving international support.
The NDC Explorer has now been taken a step further, with the NDC-SDG Connections Tool. This tool shows how joint implementation of the 2030 Agenda and the Paris Agreement can be coordinated to best effect. The tool is based on a comprehensive global analysis of all NDCs, identifying ways joint implementation offers potential synergies.


The Rulebook


What is it?

The ’rulebook’ will set out the rules for effective, equitable implementation of the Paris Agreement.

What's at stake?
The role of non-state actors in designing the rulebook is a hot topic (particularly the enhanced transparency framework, the global stocktake and the implementation and compliance mechanism).
Building trust and confidence in adequate climate action can be supported by rules on transparency and an effective review mechanism. This COP is discussing how the enhanced transparency framework can feed into the Global Stocktake and into the implementation and compliance mechanism.

Facilitative dialogue (Talanoa dialogue)


What is it?

The 2018 Facilitative Dialogue is an intergovernmental forum to focus on immediate solutions to meet the Paris Agreement’s goals and encourage raising ambition in the 163 national plans for climate action (NDCs) that countries have submitted under the agreement. Over the course of next year, it will take stock of progress that has been made and the actions that are still needed to achieve the goals of the Paris Agreement. As the COP22 and COP23 Presidencies have succinctly put it, the Facilitative Dialogue will help to answer: “Where are we?” “Where do we want to go?” And, “How do we get there?”

Why does it matter?
The Facilitative Dialogue will be a dress rehearsal for the first Global Stocktake in 2023, setting important precedents for what is meant by key provisions in the Paris Agreement such as “adequacy and effectiveness”, and “in the light of equity”. It will also provide insight into how to interpret the long-term temperature goals: what does “well below” 2°C mean, and how earnestly must we “pursue efforts” to keep warming below 1.5°C? And, even more importantly, what should these long-term targets mean in terms of our near-term actions?
