Tackling methane emissions now is a must in order to have a chance of limiting global warming to 1.5°C. The Methane Pledge is an international political initiative to reduce methane emissions 30% by 2030, but how likely is this and where would these reductions come from?
The model for Global Responses to Anthropogenic Change in the Environment (GRACE) is a multi-sector, multi-regional, recursively dynamic global computable general equilibrium model (CGE) written in GAMS and based on GTAP database. The initial version of the model was developed at CICERO by Aaheim and Rive (2005) for long-term economic analysis of climate change impacts and greenhouse gas abatement policy. It was designed to allow for additional modules for analysis, including emissions permit trading and climate impacts on economic sectors. Coupled with an atmospheric model, the model can also be used for integrated assessment modelling of the climate and economy. Since then several versions have been developed by updating data and certain modules for various studies. Go back to the general introduction.
Daily global fossil CO2 emissions fell by 17% in early April 2020 compared to 2019 amid coronavirus lockdowns in most countries, with full-year 2020 emissions set to decrease by up to 7% depending on future social distancing.
Global CO2 emissions are projected to rise a low 0.6% in 2019 due to robust growth in natural gas and oil use, and despite a decline in coal consumption. Natural gas has been the dominant driver of global emissions since 2012.
Energy use grew 2.3% in 2018, energy-related CO₂ emissions 1.7%
Norway aims to be at the forefront of both climate policy and petroleum production, while also promoting science-based policy. But what if these concerns don’t mesh?
