TF2: Climate Change and Environment
Climate change is an urgent global challenge. Scientific evidence suggests that man-made greenhouse gas emissions have already contributed to 1 degree Celsius (°C) of global warming above pre-industrial levels over the past 150 years. Global warming is likely to reach 1.5°C above pre-industrial levels between 2030 and 2052 if it continues to increase at the current rate. The Paris Agreement and Sustainable Development Goal (SDG) #13 (Climate Action) recognize the importance of collective mitigation and adaptation actions by developed and developing countries in tackling climate change at various levels.

Since the Paris Agreement came into effect in 2016, Parties to the Agreement have submitted nationally determined contributions (NDCs), setting out their climate mitigation and adaptation ambitions, and have made progress in developing climate policies. The challenge now is to translate these ambitions into actions and raise the ambition of NDCs on a five-year cyclical basis starting from 2020. Importantly, without ratcheting up NDC ambitions, current NDCs will not collectively achieve the Agreement's aim to keep the average global temperature rise to below 2°C above pre-industrial levels, let alone its aspirational target of limiting this rise to 1.5°C.

Indeed, Parties are challenged by their unique socioeconomic and environmental contexts, which necessitate different climate mitigation and adaptation approaches. It is important to acknowledge equity and common but differentiated responsibility as the key drivers of global climate change action. It is also important to recognize the spillover and negative impacts of response measures to climate change on developing countries. These countries – especially those vulnerable to climate change – shall focus on adaptation as a priority and enhance their resilience to climate change impacts. They will also contribute to climate change mitigation if adequate finance, technology and capacity building are provided.

The concept of a circular carbon economy has emerged in the climate policy debate as a way to balance economic development and environmental sustainability. T20 Saudi Arabia presents an opportunity to communicate pressing global issues to the G20. The work of this task force will therefore contribute toward speeding up nations' climate actions while ensuring environmental protection and economic growth.​
