COP27 Decarbonization Day

A crucial part of the Paris Agreement is decarbonization. This involves cutting CO2 emissions as much as possible, including in hard to abate sectors. Through policy, technology and nature based solutions decarbonization has been shown to be possible but will require immediate and radical action. November 11 at COP27 is the Decarbonization Day.

Decarbonization, and ultimately reaching net zero emissions is the ultimate goal of climate negotiations and will therefore be a central part of COP27. From the energy transition to digitalization, decarbonization has to be implemented rapidly and in a just manner

Achieving decarbonisation will rely heavily on effective policy instruments whether this be implementing a carbon market or instruments such as Europe’s Carbon Border Adjustment Mechanism. CMCC research on the technical and socioeconomic outcomes of policy instruments used to support the transition to low-carbon economies can also help inform future solutions and gather necessary data on what has been effective and what hasn’t so that we can learn from our mistakes. 

Learning from our successes and failures with the COVID-19 crisis is also critical, both in how lockdowns affected emissions in cities and high-emission sectors such as the agricultural one and the energy sector. This is not only limited to an understanding of carbon dioxide emissions but also includes other harmful gasses such as methane, because net zero goals are about more than just carbon.

Technological solutions will also be central to decarbonization through initiatives such as the digital transformation, which if properly implemented can act as an enabler and not a barrier to decarbonisation, or technologies for carbon capture and sequestration. Yes, because research increasingly indicates that we will have to not only lower emissions as much and as fast as possible but also remove excess carbon that will continue to be emitted into the atmosphere from hard-to-abate sectors.  

Yet, decarbonization is not just about policy and technology it is also about nature and how we can use nature-based solutions as a powerful tool for climate change mitigation.

Decarbonization must go hand in hand with decoupling economic growth from carbon emissions. Although this will be hard, the good news is that global economic growth is already rising faster than CO2 emissions and daunting as the challenge may seem there are examples of recent success. The solar panel revolution shows that we are moving in the right direction and that a low-carbon future is possible and makes financial sense. However, it will require engaging all stakeholders from the public sector to non-state actors.



Climate Science is Not Negotiable

As a record-breaking heatwave hit Europe, UN climate talks were underway in Bonn, Germany. However, things were not running smoothly: in a highly contentious move, a group of oil-producing countries led by Saudi Arabia refused to “welcome” the IPCC Special Report on 1.5C, citing “scientific gaps” in the report and therefore challenging the scientific basis of future decarbonisation plans. In response, the Alliance of Small Island States has voiced their support of the report and denounced the move as a negation of climate science.


Rethinking plastic use to protect the ocean and tackle climate change

Despite the increasing number of policies to reduce disposable plastic items, studies show petrochemicals are becoming the largest drivers of future global demand for oil.


The climate stories stored in trees

What does uncovering the mysteries surrounding sunken ships have in common with understanding our climate? Both involve looking at tree cores and studying the historical archives contained within their inner rings. Dendrochronology, literally the study of tree time, offers a view into the past that provides vital information about our present and future.
