Like many nations, the UK has big gaps between what is actually needed to reach net zero by 2050, what targets and ambitions have actually passed into law, and what policies are actually in place to comply with those laws. The UKâs climate watchdog, the Climate Change Committee (CCC), has issued two reports that measure the UKâs performance and makes recommendations, summarised here by Josh Gabbatiss at Carbon Brief. The first report focuses on … [Read more...]
Residential energy use: âinterventionsâ that alter daily habits vs top-down regulations
Getting people to change their behaviour is part of the net-zero plan, with residential energy consumption at 20% of total energy demand. How big a part can it play, and how quickly? Traditional methods like economic incentives and providing consumers with raw consumption data donât always get the results expected. Here, Elisabetta Cornago at the IEA describes behavioural âinterventionsâ that alter daily habits, are cheaper than large-scale … [Read more...]
18 energy transition scenarios to watch: where they agree and disagree
A wide range of regions, nations and respected organisations have created net-zero strategies and pathways, but on what do they agree and disagree? Dolf Gielen, Asami Miketa, Ricardo Gorini and Pablo Carvajal at IRENA have done a meta-analysis of 18 recent energy transition scenarios to find out. There is consensus over the main strategies: renewable power generation, and the direct and indirect electrification of end-use sectors â these account … [Read more...]
The IEA explains its new âNet-Zero Emissions by 2050â roadmap
Today the IEA publishes its new special report, âNet Zero by 2050: a Roadmap for the Global Energy Sectorâ, its deepest dive so far into whatâs needed for a successful global transition. It analyses the options as well as the socio-economic, behavioural and environmental impacts they will have globally. Here, Laura Cozzi (Chief Energy Modeller) and Timur GĂźl (Head of the Energy Technology Policy Division) at the IEA summarise the key principles … [Read more...]
Energy efficiency is the âfirst fuelâ, making decarbonisation easier for all other sectors
To set up our upcoming online event âChina: Carbon Neutral by 2060 -EFFICIENCY FIRSTâ we look at the profound importance of efficiency to the global energy transition. Energy efficiency is the âfirst fuelâ, meaning success here will make the decarbonisation of all the other sectors and technologies easier, faster and cheaper. Basically, use and waste less energy. Alyssa Fischer at the IEA starts by noting that their Sustainable Development … [Read more...]
How the global âcarbon budgetâ is calculated, and predictions improved
What is the worldâs remaining âcarbon budgetâ? Or, how much more CO2 can the Earth take before we know weâll miss our 1.5oC (and 2oC) goals for 2050. Making those calculations is not easy and IPCC benchmark estimates inevitably include levels of uncertainty in the final answer. Kasia Tokarska at the ETH Zurich Institute and Damon Matthews at Concordia University summarise their research that narrows down that uncertainty, making life a little … [Read more...]
